Approval of Plans and Specifications and Authorization to Advertise for
Bids for the Fiscal Year 2020-21 Pavement Overlay
Recommended Action
Adopt a resolution approving the plans and specifications, and authorizing the city clerk to
advertise for bids for the fiscal year 2020-21 Pavement Overlay, Capital Improvement Program
Project No. 6001-20OL.
Executive Summary
This Project is part of the City of Carlsbad’s ongoing Pavement Management Program. The
project will overlay the following streets: El Camino Real between Cannon Road and College
Boulevard, El Camino Real between Arenal Road and Levante Street, and Batiquitos Drive
between Poinsettia Lane and Camino De Las Ondas (see location map, Exhibit 2.) Given the City
Council’s authorization, staff will advertise the project for construction bids.
Carlsbad Municipal Code Section 3.28.080(E) requires the City Council to adopt plans and
specifications for all construction projects that are to be formally bid upon when the value
exceeds the $200,000 limit established by the Public Contract Code, including the alternative
provisions of the Uniform Public Construction Cost Accounting Act. The cost of the project is
estimated at $5,205,000, so the project is subject to the requirement.
Staff recommends approval of the plans and specifications, and requests authorization for the
city clerk to advertise for construction bids.
Discussion
The program uses a set of ongoing activities and practices to assess the city’s roadway
pavement conditions. Depending on the pavement conditions, the program uses appropriate
treatment methods to preserve and maintain city streets, enhance safety, improve pavement
conditions and extend the life of the roadway system. The program relies on computerized
pavement condition predictive modeling and analyses, as well as visual observation and
engineering assessment by city staff. Staff also evaluate various maintenance and rehabilitation
options, and select the most appropriate option based on the pavement conditions and how
the work will maximize the value and life of the city’s pavement network.
The pavement maintenance and rehabilitation activities on portions of El Camino Real and
Batiquitos Drive will be accomplished by utilizing a cost-effective, long-lasting and
Sept. 15, 2020 Item #3 Page 1 of 15
environmentally friendly rehabilitation method, referred to as cold in-place recycling. This is a
continuous multistep paving process in which the existing asphalt pavement is removed and
reused using specialized equipment that cold mills the asphalt pavement. It includes removing
the top four inches of the existing asphalt surface and blending the reclaimed material with an
asphalt recycling agent. The blended mix is then redeposited and compacted in-place using
paving equipment. Once the cold in-place recycling is cured, the pavement is overlaid with a
new asphalt surface layer.
As the name implies, this cold process does not require additional heat during the grinding and
construction operations, which means less energy is required to produce the final material.
Cold processing also reduces the initial project, lifecycle and trucking costs, along with
greenhouse gas emissions and other environmental impacts associated with the conventional
rehabilitation options. Additionally, the process can be used to repair relatively deep asphalt
distresses, such as rutting and fatigue cracking that cannot be fixed by a conventional surface
treatment or an overlay.
On top of the cold processed section, the project will add a polymer-modified asphalt concrete
surface layer. This layer includes a warm mix additive, which will assist with pavement
compaction operation and allow for asphalt production and pavement construction at reduced
temperatures. This will result in lower energy consumption, lower quantity of greenhouse gas
emissions and lower lifecycle environmental burden, consistent with the City of Carlsbad’s
Climate Action Plan objectives.
The combination of the cold processing and polymer-modified asphalt concrete with warm mix
additive will provide a more durable pavement material, which is expected to provide increased
resistance to rutting, fatigue cracking and other pavement distresses and extend the life of the
pavement. These pavement improvements will result in enhanced rideability, improved safety,
reduced maintenance and overall lifecycle costs.
In addition to creating a new pavement surface, staff typically reviews and refines, if necessary,
the striping and pavement markings to improve safety for all modes of travel. Typical striping
and pavement marking refinements include adding new bike lanes or enhancing existing bike
lanes, where sufficient space exists. In some cases, traffic calming measures such as narrowing
travel lanes and/or adding pavement legends that provide guidance to the drivers and bicyclists
are implemented.
As part of the project, staff is proposing to narrow the travel lanes in both directions of El
Camino Real between Cannon Road and College Boulevard, and between Arenal Road and
Levante Street, from 12 feet to 11 feet, and add 3-foot-wide striped buffers to the existing 8-
foot-wide Class-II, on-road bike lanes.1 The project will also include adding dashed green
pavement markings at the right-turn lanes vehicle-bike conflict zones. These striping
modifications are intended to improve safety for bicyclists along El Camino Real by providing
greater shy distance between motor vehicles and bicyclists and increasing the visibility of
1 California’s Streets and Highways Code defines a Class II bikeways as those that “provide a restricted right-of-way
designated for the exclusive or semi exclusive use of bicycles with through travel by motor vehicles or pedestrians
prohibited, but with vehicle parking and crossflows by pedestrians and motorists permitted.”
Sept. 15, 2020 Item #3 Page 2 of 15
bicyclists along the corridor. Shy distance is the distance from the edge of the traveled way
beyond which a roadside object will not be perceived as an immediate hazard by the typical
driver to the extent that the driver will react.
Traffic and Mobility Commission recommendation
At its meeting on May 4, 2020, the Traffic and Mobility Commission voted unanimously 7-0 to
support staff’s recommendation to implement the Pavement Management Program – Fiscal
Year 2020-21 Pavement Overlay Project, Capital Improvement Project No. 6001-20OL. The
approved minutes for this meeting are provided in Exhibit 3.
At the time of the Traffic and Mobility Commission meeting, staff had originally intended to
include slurry seal resurfacing on El Camino Real between College Boulevard and Faraday
Avenue as part of this project. After the Traffic and Mobility Commission meeting, staff
determined that the slurry seal resurfacing for this segment would be more cost-effective and
efficient if it was removed from this project and included as part of the upcoming FY 2020-21
Slurry Seal project. Staff is currently working on the FY 2020-21 Slurry Seal project and will
bring it to City Council for approval of plans and specifications, and authorization to bid, later
this year.
Fiscal Analysis
There are sufficient funds available to complete the project. Funding consists of non-
jurisdictional fees (generated from trash haulers), gas tax and TransNet funds. Remaining
program funds will be used on future pavement rehabilitation and resurfacing projects. The
available funds and estimated construction costs are shown in the following table:
PAVEMENT MANAGEMENT PROGRAM, CIP PROJECT NO. 6001
Current appropriation $10,923,694
Current year expenditures/encumbrances $1,295,238
TOTAL AVAILABLE $9,628,456
FY 2020-21 PAVEMENT OVERLAY, CIP PROJECT NO. 6001-20OL
Construction contract (engineer’s estimate) $4,732,000
Construction contingency (estimated) $473,000
Construction management, inspection, and material testing (estimated) $473,000
TOTAL ESTIMATED CONSTRUCTION COSTS $5,678,000
REMAINING BALANCE AFTER CIP No. 6001-20OL $3,950,456
ADDITIONAL APPROPRIATION NEEDED $0
Sept. 15, 2020 Item #3 Page 3 of 15
Next Steps
Given the City Council’s approval, staff will advertise a request for bids to construct the project.
Responses will be evaluated, and the lowest responsive and responsible bidder will be
identified by city staff. Staff will then return to City Council with a recommendation to award
the contract to the identified bidder. This is expected to be in early 2021. The typical time from
authorization to bid to the execution of the construction contract is four to six months. The
construction contract for the project provides for about three months to construct the
improvements.
Environmental Evaluation (CEQA)
The project is exempt from the California Environmental Quality Act per Guidelines Section
15301(c) – minor alteration of existing facilities including streets, sidewalks, gutters and similar
facilities involving negligible or no expansion.
Public Notification
Public notice of this item was posted in accordance with the Ralph M. Brown Act and it was

▫Commissioner Perez inquired about minimizing the railroad operations during construction.
▫Principal Regional Planner SANDAG Culp answered that the railroad operations will continue
during construction with minor alterations.
▫Commissioner Penseyres inquired about the timeframe to fund the project and start
construction.
▫Principal Regional Planner SANDAG Culp explained that SANDAG has a list of projects and
addresses each one based on the phase of development.
▫ Commissioner Linke inquired about the funding of the project for the next phases.
▫Principal Regional Planner SANDAG Culp explaining that there is no additional funds for this
project on SANDAG’s side.
▫Deputy City Manager Gomez explained that there were funds allocated for this initial phase
and used but because of Proposition H requirement (one-million-dollar threshold) the city will
have to go to vote for this project.
▫Commissioner Fowler inquired about the impact of the Del Mar Bluffs Stabilization project on
the Railroad Trench Project.
▫Principal Regional Planner SANDAG Culp said that the Del Mar Bluffs project is at the top five
on the priority list, but the Railroad Trench project will continue to be active on their list.
Rosita Sisson, a Carlsbad resident, send an email with the following question:
Has the City of Carlsbad made a financial commitment to contribute to the trenching project in any of its
phases, including the current phase?
Principal Regional Planner SANDAG Culp said yes, the first phase feasibility studies the city funded part
of it (the economic analysis) and the current phase alternatives analysis was funded 100% by the City of
Carlsbad.
3.MELROSE AT PALOMAR AIRPORT ROAD IMPROVEMENTS– (Staff Contact: Brandon Miles and
Hossein Ajideh, Public Works)
Staff’s Recommendation: Approve staff recommendations
Engineering Manager Ajideh and Associate Engineer Miles presented the Melrose Drive
Improvements at Palomar Airport Road, Capital Improvement Program (CIP) Project No. 6034
(Project) providing operational improvements consistent with the city’s General Plan Mobility
Element. Presentation is on file with the office of the City Clerk.
▫Commissioner Hunter inquired about the possibility to include a left turn bicycle lane, it would
be a pilot program because there are no left turn bike lanes.
▫Engineering Manager Ajideh said that staff can look at the request with the Traffic Division.
▫Commissioner Perez asked if for the future presentations if staff could provide a street view,
virtual view of the layout.
▫Associate Engineer Miles said yes.
▫Commissioner Penseyres inquired about the southbound on Melrose Drive if it is possible to
make the bike lane wider and painted green.
▫Associate Engineer Miles said that staff will work with the Traffic Division to make possible
enhancing the bike lane as requested.
▫Commissioner Penseyres inquired about the northbound on Melrose Drive and the possibility of
having a left turn lane designated for bicycles.
Sept. 15, 2020 Item #3 Page 9 of 15
▫Associate Engineer Miles answered that staff will work with Traffic Division look at the proper
design guidelines on the request.
▫Transportation Director confirmed that staff will look at the proper design guidelines and the
current measure is to paint the bike lane green on conflicting areas.
Motion by Commissioner Hunter seconded by Commissioner Linke to approve staff recommendation to
implement operational improvements on Melrose Drive at Palomar Airport Road CIP Project No. 6034,
including the stripping on northbound Melrose Drive.
Motion carried: 7/0
4.FISCAL YEAR 2020-21 PAVEMENT OVERLAY– (Staff Contact: Emad Elias, Public Works)
Staff’s Recommendation: Approve staff recommendations
Engineering Manager Ajideh and Associate Engineer Elias presented the Pavement Management
Program Implementation - Fiscal Year (FY) 2020-21 Pavement Overlay Project (Project), Capital
Improvement Program (CIP) Project No. 6001-20OL. Presentation is on file with the office of the
City Clerk.
▫ Commissioner Hunter inquired about the future project to add a third lane on El Camino Real
from Jackspar Drive to Sunny Creek Drive and the overlay pavement getting damaged during
construction.
▫ Engineering Manager Ajideh explained that if City Council approves the project to add a third
lane on El Camino Real, staff will revise the roads selected for pavement overlay.
▫Commissioner Penseyres was happy to see dedicated right turn lane because it makes it safer
for cyclists but he pointed out that several intersections do not have dedicated right turn lane and
it makes unsafe for the cyclists.
▫Deputy City Manager Gomez shared with the commissioners that Street Maintenance Division
is now under Transportation Department.
▫Commissioner Linke noted that he submitted questions related to this item and he inquired
about the Pavement Condition Index (PCI) numbers for the three streets.
▫Engineering Manager Ajideh answered that he could share the model numbers of the PCI with
him but overall the range of PCI in those areas are mid to high 60 based on the model.
▫Commissioner Linke is in favor of doing pavement overlays when necessary and improving bike
lanes whenever possible. However, he sees that large proportion of TransNet funds have been
used over the years for these repair projects, which instead could use general funds without
generating a Proposition H election requirement. Therefore, he would like to see the TransNet
funds re-allocated to street improvement projects, like the extension of College Boulevard, which
are more likely to be subject to Proposition H.
▫Engineering Manager Ajideh said that for the next two years staff will not use the TransNet funds
for pavement overlay because of a surplus funds that the city has with Trash Haulers.
▫ Deputy City Manager Gomez mentioned the availability of the SB 1 funds which is relatively new
and will give us an opportunity to review the program’s funding holistically.
▫Chair Gocan observed that the last pavement overlay looked like a paint over the road, over the
cracks and weeds that were growing in the asphalt. She inquired about staff inspecting the job
and doing a quality control.
Sept. 15, 2020 Item #3 Page 10 of 15
Motion by Commissioner Hunter, seconded by Commissioner Penseyres, to approve staff
recommendations to implement the Pavement Management Program - Fiscal Year (FY) 2020-21
Pavement Overlay Project, Capital Improvement Program (CIP) Project No. 6001-20OL
Motion carried: 7/0
Motion by vice-Chair Johnson, seconded by Commissioner Perez to take a five minutes break.
Chair Gocan observed that all the commissioners agreed and no vote was taken.
5.RECTANGULAR RAPID FLASHING BEACONS AT THREE LOCATIONS - (Staff Contact: Edd
Alberto, Public Works)
Staff’s Recommendation: Approve staff recommendations
Associate Engineer Alberto presented the recommendation to install Rectangular Rapid Flashing Beacons (RRFB) at the intersections of Paseo Del Norte/Elder Court, Monroe Street/Magnolia Avenue, and Salk Avenue/Fermi Court. Capital Improvement Program (CIP) Project No. 6070. Presentation is on file with the office of the City Clerk.
▫Commissioner Hunter inquired about the location on Salk Avenue and the reasoning behind the
installation of the RRFB; was it because of the TaylorMade Golf course on one side and the test
range on the other side.
▫ City Traffic Engineer Kim said yes and because of TaylorMade Golf course employee’s request.
▫ Commissioner Perez asked if the RRFB is like the ones installed on Tamarack Avenue.
▫ Associate Engineer Alberto said yes.
▫Commissioner Penseyres inquired about the point system for prioritizing crossing locations that
staff developed. He believes that intersections with a reported pedestrian collision should be on
the top of the list.
▫City Traffic Engineer Kim answered that staff uses the point system from the City of San Diego
Crosswalk Policy and five points were given if there was a pedestrian-related accident at the
intersection.
▫ Vice-chair Johnson inquired about intersection on Salk Avenue/Fermi Court, there are no schools
and very segregated location.
▫City Traffic Engineer Kim said it was related to the speed limit on Salk Avenue and the
TaylorMade Golf course employees request.
▫Chair Gocan explained that the signs are not tall enough and the spacing between the signs
should be bigger to make it more visible.
▫Associate Engineer Alberto said that staff will consider the request and look to the possibility of
making changes.
▫City Traffic Engineer Kim said that the RRFB signs are standardized by the FHWA as an interim
approval granted to California. The city is following the guidelines found in the FHWA interim
approval.
Motion by Commissioner Linke, seconded by Commissioner Hunter to approve staff recommendations to
install Rectangular Rapid Flashing Beacons at the intersections of Paseo Del Norte/Elder Court, Monroe
Street/Magnolia Avenue, and Salk Avenue/Fermi Court. CIP No. 6070.
Motion carried: 7/0
Sept. 15, 2020 Item #3 Page 11 of 15
6.TRAFFIC CALMING ON COLLEGE BOULEVARD - (Staff Contact: John Kim, and Tom Frank,
Public Works) –
Staff’s Recommendation: Approve staff recommendations
City Traffic Engineer Kim and Transportation Director Frank presented the Traffic Calming on
College Boulevard requesting T&MC to support staff’s recommendation provided in the staff
report as Option 1 – Radar Speed Feedback Signs. Presentation is on file with the office of the
City Clerk.
Public comments submitted via email prior to the T&MC meeting:
Calavera Hills Traffic Safety Group, constituted of 21 Carlsbad residents submitted a letter with a
survey results on the Traffic Calming on Carlsbad Boulevard options presented by staff. The
survey shows that Calavera Hills Traffic Safety Group chose Option 1, as recommended by staff.
Letter is on file with the office of the City Clerk.
▫Commissioner Perez agreed that Option 1 is a good option but he believes that the speed limit,
level of congestion and traffic behavior should be taken in consideration to make an informed
decision. College Boulevard is a dynamic road with different speed limits, congestion levels, and
traffic behavior throughout the day due to two schools affecting College Boulevard between
northern city limits and Cannon Road.
▫Commissioner Penseyres does not believe that Option 1 will solve the problem, but it might
only delay the problem temporarily. He is in favor of the Option 1 because it was supported by
the Calavera Hills Traffic Safety Group.
▫Commissioner Linke thanked staff for providing 5 years of collision data where everyone can
see the clusters of collisions close to schools. Commissioner Linke inquired about speed data
available for this area.
▫City Traffic Engineer Kim explained that we have speed survey data on file that was collected
to determine speed limits but those are limited to off-peak hours on a given day. Once the
speed feedback signs are installed, the city can collect data 24 hours a day.
▫Commissioner Linke inquired if the city has data on the efficiency of the speed feedback signs
installed on other areas.
▫City Traffic Engineer Kim answered that most of the speed feedback signs in the city are
located on residential areas and not arterials like College Boulevard. On residential streets,
decreases around 5 mph were observed.
▫Commissioner Linke inquired about installing a restricted “right turn on red” on the
intersection of College Boulevard and Tamarack Avenue.
▫Commissioner Linke showed photos of the southern Tamarack Avenue intersection with
Carlsbad Boulevard during the morning rush hour, highlighting a school crossing guard’s
concerns about (1) conflicts between pedestrians crossing College and vehicles going eastbound
on Tamarack turning left (north) onto College, and (2) conflicts between bicyclists and vehicles
traveling northbound on College.
▫Commissioner Linke expressed concern about the cluster of collisions near the Calavera Hills
schools and expressed support for speed feedback signs as an initial step. He questioned
whether the signs alone would be sufficient to resolve the problem and supported continued
exploration of the feasibility of intersection changes.
▫City Traffic Engineer Kim said that the city is evaluating if “no right turn on red” could be
feasible and if we could restrict the time it would be in operation.
Sept. 15, 2020 Item #3 Page 12 of 15
▫Commissioner Fowler wanted clarification that College Boulevard was built as a major arterial
per standards in the Circulation Element of the previous General Plan.
▫Transportation Director Frank explained that California roads were built primarily for vehicles
and the new Mobility Element calls for revising the roads as Complete Streets and that will be
costly.
▫City Traffic Engineer Kim explained that College Boulevard was built as an arterial based on the
previous General Plan and once the Mobility Element was implemented College Boulevard
continued to be labeled as an arterial.
▫Commissioner Hunter inquired about the speed limit survey data when it was done and what
was the 85th percentile.
▫City Traffic Engineer Kim said that the survey was collected in October of 2018 and the 85th
percentile was 48mph based on 100 vehicles.
Motion by Commissioner Hunter, seconded by Commissioner Linke, to approve staff’s recommendations
to implement Option 1 – Radar Speed Feedback Signs, adding to re-evaluate the item later and collect
speed survey data.
Motion carried: 7/0
Motion by Commissioner Hunter, seconded by Commissioner Fowler to take a five minutes break.
Motion carried: 7/0
7.VEHICLE MILES TRAVELED THRESHOLDS AND SCREENING CRITERIA – (Staff Contact: Jason
Geldert and Jennifer Horodyski, Community and Economic Development)
Staff’s Recommendation: Approve staff recommendations
Engineering Manager Geldert is asking the T&MC to recommend to City Council the adoption of
a resolution to approve citywide the Vehicle Miles Traveled thresholds and screening criteria
pursuant to Senate Bill 743.
▫ Commissioner Linke stated that the City of Carlsbad is approaching build-out and asked what
proportion of development projects, remain to be done that could be subject to the Vehicle
Miles Traveled (VMT) guidelines.
▫Engineering Manager Geldert answered that currently we have 2 or 3 projects that will have to
evaluate VMT, but did not have exact numbers. He estimated that quite a few projects are
expected to be subject to VMT analysis guidelines.
▫Commissioner Linke asked about the following hypothetical scenario: In the area that is mostly
the Village and the Barrio (light blue area shown in the power point), per capita VMT is 85% or
less than the city average so, under the 2,400 ADT threshold, does that mean that anyone could
build a residential area up to 240 single-family homes, or 400 apartments, or a 600-unit
retirement community and not be subject to the VMT analysis?
▫Associate Engineer Horodyski explained that yes, according to the VMT guidelines, if the city
average is more than 15%, the area would not be subject to the VMT guidelines.
▫Commissioner Linke is concerned that a developer could build a 600-unit apartment complex in
one of the light blue zones and be able to say that we are not generating vehicle miles out of
the 600 units as an example.
Sept. 15, 2020 Item #3 Page 13 of 15
▫Engineer Manager Geldert explained that he understands Commissioner Linke concerns and he
agrees that any project based on this example would generate VMT however, the metric that we
are using is an efficiency metric which means that is a VMT per person.
▫Project Manager Cole stated the key here is the efficiency metric uses an existing apartment
complex that on average is generating 15 VMT per person and if another apartment complex is
built nearby the expectation is that it will be like the existing neighbors.
▫Commissioner Linke expressed concern that, with the proposed thresholds, the city would not
be able to compel even relatively large developments to fund any mitigation measures like
transit or other Transportation Demand Management (TDM) measures that could be used to
encourage the new residents to not drive their cars.
▫Commissioner Linke asked if there is anything that has been customized or is unique for the
City of Carlsbad.
▫Associate Engineer Horodyski explained that City of Carlsbad has a couple of thresholds and
screening criteria that are unique, one is the threshold for Office projects and the other is the
Industrial projects.
▫Commissioner Linke inquired about harmonizing CEQA rules/TDM rules/ Growth Management
Program (GMP) rules/VMT and Level of Service (LOS).
▫Associate Engineer Horodyski explained that staff will continue to require both analysis: one for
CEQA one for local Traffic Impact Analysis (TIA) and will combine into one document.
▫Engineering Manager Geldert stated that as a result of harmonizing the documents staff will
develop TIA guidelines, addressing the rules and regulations cited above.
▫Commissioner Perez inquired if the development of Robertson’s Ranch will affect VMT.
▫Director of Traffic Engineering Ruehr answered that for the analysis of this specific commercial
project, Robertson’s Ranch, it is assumed that this development would decrease VMT.
▫Commissioner Penseyres pointed out that one of the areas in the city under development is
around Sage Creek High School and how the VMT would impact the residential development in
the area.

TRAFFIC & MOBILITY COMMISSION COMMENTS:
Commissioner Linke mentioned that the first ad-hoc meeting on the Sustainable Mobility Plan went well
and he is cautiously optimist that they can make it better.
Commissioners Penseyres inquired about having an information on the Multimodal Level of Service, to
better understand how it works.
Transportation Planning and Mobility Manager Schmidt said that it is staff intention to bring it to the
T&MC and give a quick primer on how MMLOS is calculated for bicyclists and pedestrians.
Commissioner Penseyres explained his reasoning behind asking for more frequent street sweeping on a
wider bicycle lane is to address the debris that accumulates on the bicycle lane.
Transportation Director Frank answered that staff will consider his request.

Chair Gocan adjourned the Traffic & Mobility Commission Meeting on May 4, 2020, at 8:01 p.m.

REFERENCES Prior to preparation of the following “Subcontractor Disclosure Form” Bidders are urged to review the definitions in section 1-2 of the General Provisions to this Contract, especially, “Bid”, “Bidder”, “Contract”, “Contractor”, “Contract Price”, “Contract Unit Price”, “Engineer”, “Own Organization”, “Subcontractor”, and “Work”. Bidders are further urged to review sections 2-3 SUBCONTRACTS of the General Provisions. CAUTIONS This form will be used by the Agency to determine the percentage of work that the Bidder proposes to perform. Bidders are cautioned that failure to provide complete and correct information may result in rejection of the bid as non-responsive. Any bid that proposes
performance of more than 50 percent of the work by subcontractors or otherwise to be performed by forces other than the Bidder’s own organization will be rejected as non-responsive. Specialty items of work that may be so designated by the Engineer on the “Contractor’s Proposal” are not
included in computing the percentage of work proposed to be performed by the Bidder. INSTRUCTIONS The Bidder shall set forth the name and location of business of each and every subcontractor whom the Bidder proposes to perform work or labor or render service in or about the work or improvement, and every subcontractor licensed as a contractor by the State of California whom the Bidder proposes to specially fabricate and install any portion of the work or improvement according to detailed drawings contained in the plans and specifications in excess of one-half of one percent (0.5%) of the Bidder’s total bid or, in the case of bids or offers for the construction of streets and highways, including bridges, in excess of one-half of one percent (0.5%) or ten thousand dollars ($10,000) whichever is greater. Said name(s) and location(s) of business of subcontractor(s) shall be set forth and included as an integral part of the bid offer.
The Designation of Subcontractors form must be submitted as a part of the Bidder’s sealed bid. Failure to provide complete and correct information may result in rejection of the bid as non-
responsive. Suppliers of materials from sources outside the limits of work are not subcontractors. The value
of materials and transport of materials from sources outside the limits of work, as shown on the plans, shall be assigned to the Contractor or the Subcontractor as the case may be, that the Bidder proposes as installer of said materials. The value of material incorporated in any
Subcontractor-installed bid item that is supplied by the Bidder shall be included as a part of the work that the Bidder proposes to be performed by the Subcontractor installing said item. When a Subcontractor has a Carlsbad business license, the number must be entered on the proper form. If the Subcontractor does not have a valid business license, enter “NONE” in the appropriate space. When the Bidder proposes using a Subcontractor to construct or install less than 100 percent of a bid item, the Bidder shall attach an explanation sheet to the Designation of Subcontractor form. The explanation sheet shall clearly apprise the City of the specific facts that show the Bidder proposes to perform no less than fifty percent (50%) of the work with its own forces.
Determination of the subcontract amounts for purposes of award of the contract shall be deter- mined by the City Council in conformance with the provisions of the contract documents and the various supplemental provisions. The decision of the City Council shall be final.

SECTION 2 – SCOPE AND CONTROL OF WORK
2-1 AWARD AND EXECUTION OF CONTRACT. Award and execution of Contract will be as provided for in the Specifications, Instruction to Bidders, or Notice Inviting Bids.
2-2 ASSIGNMENT. No Contract or portion thereof may be assigned without consent of the Board, except that the Contractor may assign money due or which will accrue to it under the
Contract. If given written notice, such assignment will be recognized by the Board to the extent permitted by law. Any assignment of money shall be subject to all proper withholdings in favor of the Agency and to all deductions provided for in the Contract. All money withheld, whether
assigned or not, shall be subject to being used by the Agency for completion of the Work, should the Contractor be in default. 2-3 SUBCONTRACTS. 2-3.1 General. Each Bidder shall comply with the Chapter of the Public Contract Code including
Sections 4100 through 4113. The following excerpts or summaries of some of the requirements of this Chapter are included below for information:
The Bidder shall set forth in the Bid, as provided in 4104: “(a) The name and location of the place of business of each subcontractor who will perform work or labor or render service to the prime contractor in or about the construction of the work or improvements, or a subcontractor licensed by the State of California who, under subcontract to the prime contractor, specially fabricates and installs a portion of the work or improvement according to detailed drawings contained in the plans and specifications, in an amount in excess of one-half of 1 percent of the prime contractor’s total bid, or, in the case of bids or offers for the construction of streets or highways, including bridges, in excess of one-half of 1 percent of the prime contractor’s total bid or ten thousand dollars ($10,000),
whichever is greater.” “(b) The portion of the work which will be done by each such subcontractor under
this act. The prime contractor shall list only one subcontractor for each such portion as is defined by the prime contractor in his bid.”
If the Contractor fails to specify a Subcontractor or specifies more than one Subcontractor for the same portion of the work to be performed under the Contract (in excess of one-half of 1 percent of the Contractor’s total Bid), the Contractor shall be qualified to perform that portion itself, and shall perform that portion itself, except as otherwise provided in the Code. As provided in Section 4107, no Contractor whose Bid is accepted shall substitute any person as Subcontractor in place of the Subcontractor listed in the original Bid, except for causes and by procedures established in Section 4107.5. This section provides procedures to correct a clerical error in the listing of a Subcontractor. Section 4110 provides that a Contractor violating any of the provisions of the Chapter violates the
Contract and the Board may exercise the option either to cancel the Contract or assess the
Revised 6/15/2017 Contract No. 6001-20OL Page 55 of 148
Contractor a penalty in an amount of not more than 10 percent of the subcontract involved, after a public hearing.
Should the Contractor fail to adhere to the provisions requiring the Contractor to complete 50 percent of the contract price with its own organization, the Agency may at its sole discretion
elect to cancel the contract or deduct an amount equal to 10 percent of the value of the work performed in excess of 50 percent of the contract price by other than the Contractor’s own organization. The Board shall be the sole body for determination of a violation of these provisions. In any proceedings under this section, the prime contractor shall be entitled to a public hearing before the Board and shall be notified ten (10) days in advance of the time and location of said hearing. The determination of the City Council shall be final. 2-3.2 Additional Responsibility. The Contractor shall give personal attention to the fulfillment of the Contract and shall keep the Work under its control. The Contractor shall perform, with its own organization, Contract work amounting to at least
50 percent of the Contract Price except that any designated “Specialty Items” may be performed by subcontract, and the amount of any such “Specialty Items” so performed may be deducted from the Contract Price before computing the amount required to be performed by the Contractor
with its own organization. “Specialty Items” will be identified by the Agency in the Bid or Proposal. Where an entire item is subcontracted, the value of work subcontracted will be based on the Contract Unit Price. When a portion of an item is subcontracted, the value of work subcontracted
will be based on the estimated percentage of the Contract Unit Price. This will be determined from information submitted by the Contractor, and subject to approval by the Engineer. Before the work of any Subcontractor is started, the Contractor shall submit to the Engineer for approval a written statement showing the work to be subcontracted giving the name and business of each Subcontractor and description and value of each portion of the work to be so subcontracted. 2-3.3 Status of Subcontractors. Subcontractors shall be considered employees of the Contractor, and the Contractor shall be responsible for their work. 2-4 CONTRACT BONDS. Before execution of the Contract, the Bidder shall file surety bonds with the Agency to be approved by the Board in the amounts and for the purposes noted below. Bonds issued by a surety, who is authorized to issue bonds in California, and whose bonding limitation shown in said circular is sufficient to provide bonds in the amount required by
the Contract shall be deemed to be approved unless specifically rejected by the Agency. Bonds from all other sureties shall be accompanied by all of the documents enumerated in Code of Civil Procedure 995.660 (a). The Bidder shall pay all bond premiums, costs, and incidentals. Each bond shall incorporate, by reference, the Contract and be signed by both the Bidder and Surety and the signature of the authorized agent of the Surety shall be notarized. The Contractor shall provide a faithful performance/warranty bond and payment bond (labor and materials bond) for this contract. The faithful performance/warranty bond shall be in a sum not less than one hundred percent of the total amount payable by the terms of this contract. The Contractor shall provide bonds to secure payment of laborers and materials suppliers in a
sum not less than one hundred percent of the total amount payable by the terms of this contract.
Revised 6/15/2017 Contract No. 6001-20OL Page 56 of 148
Both bonds shall extend in full force and effect and be retained by the Agency during this project until they are released according to the provisions of this section.
The faithful performance/warranty bond will be reduced to 25 percent of the original amount 30 days after recordation of the Notice of Completion and will remain in full force and effect for
the one year warranty period and until all warranty repairs are completed to the satisfaction of the Engineer. The bonds to secure payment of laborers and materials suppliers shall be released six months plus 30 days after recordation of the Notice of Completion if all claims have been paid. All bonds are to be placed with a surety insurance carrier admitted and authorized to transact the business of insurance in California and whose assets exceed their liabilities in an amount equal to or in excess of the amount of the bond. The bonds are to contain the following documents:
1) An original, or a certified copy, of the un-revoked appointment, power of attorney, by laws, or other instrument entitling or authorizing the person who executed the bond to do so. 2) A certified copy of the certificate of authority of the insurer issued by the insurance commissioner. If the bid is accepted, the Agency may require a financial statement of the assets and liabilities of the insurer at the end of the quarter calendar year prior to 30 days next preceding the date of the
execution of the bond. The financial statement shall be made by an officer's certificate as defined in Section 173 of the Corporations Code. In the case of a foreign insurer, the financial statement may be verified by the oath of the principal officer or manager residing within the United States.
Should any bond become insufficient, the Contractor shall renew the bond within 10 days after receiving notice from the Agency. Should any Surety at any time be unsatisfactory to the Board, notice will be given the Contractor to that effect. No further payments shall be deemed due or will be made under the contract until a new Surety shall qualify and be accepted by the Board. Changes in the Work or extensions of time, made pursuant to the Contract, shall in no way release the Contractor or Surety from its obligations. Notice of such changes or extensions shall be waived by the Surety.

The Contractor shall
transfer them to the bottom of the trench. 2-10 AUTHORITY OF BOARD AND ENGINEER. The Board has the final authority in all
matters affecting the Work. Within the scope of the Contract, the Engineer has the authority to
enforce compliance with the Plans and Specifications. The Contractor shall promptly comply with instructions from the Engineer or an authorized representative. The decision of the Engineer is final and binding on all questions relating to: quantities; acceptability of material, equipment, or work; execution, progress or sequence of work; and interpretation of the Plans, Specifications, or other drawings. This shall be precedent to any payment under the Contract, unless otherwise ordered by the Board. 2-10.1 Availability of Records, The Contractor shall, at no charge to the Agency, provide copies of all records in the Contractor’s or subcontractor’s possession pertaining to the work that the Engineer may request. 2-10.2 Audit and Inspection, Contractor agrees to maintain and/or make available, to the Engineer, within San Diego County, accurate books and accounting records relative to all its

SECTION 3 – CHANGES IN WORK
3-1 CHANGES REQUESTED BY THE CONTRACTOR. 3-1.1 General. Changes in the Plans and Specifications, requested in writing by the Contractor, which do not materially affect the Work and which are not detrimental to the Work or to the interests of the Agency, may be granted by the Engineer. Nothing herein shall be construed as granting a right to the Contractor to demand acceptance of such changes. 3-1.2 Payment for Changes Requested by the Contractor. If such changes are granted, they shall be made at a reduction in cost or no additional cost to the Agency. 3-2 CHANGES INITIATED BY THE AGENCY. 3-2.1 General. The Agency may change the Plans, Specifications, character of the work, or quantity of work provided the total arithmetic dollar value of all such changes, both additive and deductive, does not exceed 25 percent of the Contract Price. Should it become necessary to exceed this limitation, the change shall be by written Supplemental Agreement between the Contractor and Agency, unless both parties agree to proceed with the change by Change Order. Change Orders shall be in writing and state the dollar value of the change or established method of payment, any adjustment in contract time of completion, and when negotiated prices are involved, shall provide for the Contractor’s signature indicating acceptance. 3-2.2 Payment. 3-2.2.1 Contract Unit Prices. If a change is ordered in an item of work covered by a Contract
Unit Price, and such change does not involve substantial change in character of the work from that shown on the Plans or specified in the Specifications, then an adjustment in payment will be made. This adjustment will be based upon the increase or decrease in quantity and the Contract Unit Price. If the actual quantity of an item of work covered by a Contract Unit Price and constructed in conformance with the Plans and Specifications varies from the Bid quantity by 50 percent or less, payment will be made at the Contract Unit Price. If the actual quantity of said item of work varies from the Bid quantity by more than 50 percent, payment will be made per Section 3-2.2.2 or 3-2.2.3 as appropriate. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does involve a substantial change in the character of the work from that shown on the Plans or specified in the Specifications, an adjustment in payment will be made per Section 3-2.4.
3-2.2.2 Increases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price and constructed in conformance with the Plans and
Specifications, exceed the Bid quantity by more than 50 percent, payment for the quantity in excess of 150 percent of the Bid quantity will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3. The Extra Work per Section 3-3, basis of
Revised 6/15/2017 Contract No. 6001-20OL Page 64 of 148
payment, shall not include fixed costs. Fixed costs shall be deemed to have been recovered by the Contractor through payment for 150 percent of the Bid quantity at the Contract Unit Price. 3-2.2.3 Decreases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price, and constructed in conformance with the Plans and
Specifications, be less than 50 percent of the Bid quantity, an adjustment in payment will not be made unless so requested in writing by the Contractor. If the Contractor so requests, payment will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3; however, in no case will payment be less than would be made for the actual quantity at the Contract Unit Price nor more than would be made for 50 percent of the Bid quantity at the Contract Unit Price. 3-2.3 Stipulated Unit Prices. Stipulated Unit Prices are unit prices established by the Agency in the Contract Documents as distinguished from Contract Unit Prices submitted by the Contractor. Stipulated Unit Prices may be used for the adjustment of Contract changes when so
specified in the Special Provisions. 3-2.4 Agreed Prices. Agreed Prices are prices for new or unforeseen work, or adjustments in
Contract Unit Prices per Section 3-2.2, established by mutual agreement between the Contractor and the Agency. If mutual agreement cannot be reached, the Engineer may direct the Contractor to proceed on the basis of Extra Work in accordance per Section 3-3, except as otherwise
specified in Sections 3-2.2.2 and 3-2.2.3. 3.2.4.1 Schedule of Values. Prior to construction, Contractor shall provide a schedule of values for all lump sum bid items that shall be used for the purpose of progress payments. The prices shall be valid for the purpose of change orders to the project. 3.2.5 Eliminated Items. Should any Bid item be eliminated in its entirety, payment will be made to the Contractor for its actual costs incurred in connection with the eliminated item prior to notification in writing from the Engineer so stating its elimination. If material conforming to the Plans and Specifications is ordered by the Contractor for use in the eliminated item prior to the date of notification of elimination by the Engineer, and if the order for that material cannot be
canceled, payment will be made to the Contractor for the actual cost of the material. In this case, the material shall become the property of the Agency. Payment will be made to the Contractor for its actual costs for any further handling. If the material is returnable, the material shall be returned
and payment will be made to the Contractor for the actual cost of charges made by the supplier for returning the material and for handling by the Contractor. Actual costs, as used herein, shall be computed on the basis of Extra Work per Section 3-3.
3-3 EXTRA WORK. 3-3.1 General. New or unforeseen work will be classified as “extra work” when the Engineer determines that it is not covered by Contract Unit Prices or stipulated unit prices. 3-3.2 Payment. 3-3.2.1 General. When the price for the extra work cannot be agreed upon, the Agency will pay
for the extra work based on the accumulation of costs as provided herein.
Revised 6/15/2017 Contract No. 6001-20OL Page 65 of 148
3-3.2.2 Basis for Establishing Costs.
(a) Labor. The costs of labor will be the actual cost for wages of workers performing the extra work at the time the extra work is done, plus employer payments of payroll taxes, workers compensation insurance, liability insurance, health and welfare, pension, vacation, apprenticeship
funds, and other direct costs, resulting from Federal, State, or local laws, as well as assessments or benefits required by lawful collective bargaining agreements. The use of a labor classification which would increase the extra work cost will not be permitted unless the Contractor establishes the necessity for such additional costs. Labor costs for equipment operators and helpers shall be reported only when such costs are not included in the invoice for equipment rental. The labor cost for foremen shall be proportioned to all of their assigned work and only that applicable to extra work will be paid. Nondirect labor costs, including superintendence, shall be considered part of the markup of Section 3-3.2.3 (a).
(b) Materials. The cost of materials reported shall be at invoice or lowest current price at which such materials are locally available and delivered to the job site in the quantities involved, plus
sales tax, freight, and delivery. The Agency reserves the right to approve materials and sources of supply, or to supply materials
to the Contractor if necessary for the progress of the Work. No markup shall be applied to any material provided by the Agency. (c) Tool and Equipment Rental. No payment will be made for the use of tools which have a replacement value of $200 or less. Regardless of ownership, the rates and right-of-way delay factors to be used in determining rental and delay costs shall be the edition of the, “Labor Surcharge and Equipment Rental Rates” published by CALTRANS, current at the time of the actual use of the tool or equipment. The right-of-way delay factors therein shall be used as multipliers of the rental rates for determining the value of costs for delay to the Contractor and subcontractors, if any. The labor surcharge rates
published therein are not a part of this contract. The rental rates paid shall include the cost of fuel, oil, lubrication, supplies, small tools, necessary
attachments, repairs and maintenance of any kind, depreciation, storage, insurance, and all incidentals. Necessary loading and transportation costs for equipment used on the extra work shall be included.
If equipment is used intermittently and, when not in use, could be returned to its rental source at less expense to the Agency than holding it at the Work site, it shall be returned, unless the Contractor elects to keep it at the Work site, at no expense to the Agency. All equipment shall be acceptable to the Engineer, in good working condition, and suitable for the purpose for which it is to be used. Manufacturer’s ratings and approved modifications shall be used to classify equipment and it shall be powered by a unit of at least the minimum rating recommended by the manufacturer.
Revised 6/15/2017 Contract No. 6001-20OL Page 66 of 148
The reported rental time for equipment already at the Work site shall be the duration of its use on the extra work. This time begins when equipment is first put into actual operation on the extra
work, plus the time required to move it from its previous site and back, or to a closer site. (d) Other Items. The Agency may authorize other items which may be required on the extra
work, including labor, services, material, and equipment. These items must be different in their nature from those required for the Work and be of a type not ordinarily available from the Contractor or Subcontractors. Invoices covering all such items in detail shall be submitted with the request for payment. (e) Invoices. Vendors’ invoices for material, equipment rental and other expenditures shall be submitted with the request for payment. If the request for payment is not substantiated by invoices or other documentation, the Agency may establish the cost of the item involved at the lowest price which was current at the time of the report.
3-3.2.3 Markup. (a) Work by Contractor. The following percentages shall be added to the Contractor's costs
and shall constitute the markup for all overhead and profits: 1) Labor .............................................. 20
2) Materials ......................................... 15
3) Equipment Rental ........................... 15
4) Other Items and Expenditures ........ 15
To the sum of the costs and markups provided for in this section, 1 percent shall be added as compensation for bonding. (b) Work by Subcontractor. When all or any part of the extra work is performed by a Subcontractor, the markup established in Section 3-3.2.3(a) shall be applied to the Subcontractor's actual cost of such work. A markup of 10 percent on the first $5,000 of the subcontracted portion of the extra work and a markup of 5 percent on work added in excess of $5,000 of the subcontracted portion of the extra work may be added by the Contractor. 3-3.3 Daily Reports by Contractor. When the price for the extra work cannot be agreed upon, the Contractor shall submit a daily report to the Engineer on forms approved by the Agency.
Included are applicable delivery tickets, listing all labor, materials, and equipment involved for that day, and other services and expenditures when authorized. Payment for extra work will not be made until such time that the Contractor submits completed daily reports and all supporting
documents to the Engineer. Failure to submit the daily report by the close of the next working day may waive any rights for that day. An attempt shall be made to reconcile the report daily, and it shall be signed by the Engineer and the Contractor. In the event of disagreement, pertinent notes shall be entered by each party to explain points which cannot be resolved immediately. Each party shall retain a signed copy of the report. Reports by Subcontractors or others shall be submitted through the Contractor. The report shall:
1. Show names of workers, classifications, and hours worked.
Revised 6/15/2017 Contract No. 6001-20OL Page 67 of 148
2. Describe and list quantities of materials used.
3. Show type of equipment, size, identification number, and hours of operation, including
loading and transportation, if applicable.
4. Describe other services and expenditures in such detail as the Agency may require.
3-4 CHANGED CONDITIONS. The Contractor shall promptly notify the Engineer of the following Work site conditions (hereinafter called changed conditions), in writing, upon their discovery and before they are disturbed:
1. Subsurface or latent physical conditions differing materially from those represented in the Contract;
2. Unknown physical conditions of an unusual nature differing materially from those ordinarily encountered and generally recognized as inherent in work of the character being performed; and
3. Material differing from that represented in the Contract which the Contractor believes
may be hazardous waste, as defined in Section 25117 of the Health and Safety Code, that is required to be removed to a Class I, Class II, or Class III disposal site in accordance with provisions of existing law.
The Engineer will promptly investigate conditions which appear to be changed conditions. If the Engineer determines that conditions are changed conditions and they will materially affect performance time, the Contractor, upon submitting a written request, will be granted an extension of time subject to the provisions of 6-6. If the Engineer determines that the conditions do not justify an adjustment in compensation, the Contractor will be notified in writing. This notice will also advise the Contractor of its obligation to
notify the Engineer in writing if the Contractor disagrees. The Contractor’s failure to give notice of changed conditions promptly upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith. The Contractor shall not be entitled to the payment of any additional compensation for any act, or
failure to act, by the Engineer, including failure or refusal to issue a change order, or for the happening of any event, thing, occurrence, or other cause, unless the Contractor shall have first given the Engineer due written notice of potential claim as hereinafter specified. Compliance with this section shall not be required as a prerequisite to notice provisions in Section 6-7.3 Contract Time Accounting, nor to any claim that is based on differences in measurement or errors of computation as to contract quantities. The written notice of potential claim for changed conditions shall be submitted by the Contractor to the Engineer upon their discovery and prior to the time that the Contractor performs the work giving rise to the potential claim. The Contractor’s failure to give written notice of potential claim for changed conditions to the agency upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith.
The Contractor shall provide the City with a written document containing a description of the particular circumstances giving rise to the potential claim, the reasons for which the Contractor believes additional compensation may be due and nature of any and all costs involved within 20
working days of the date of service of the written notice of potential claim for changed conditions. Verbal notifications are disallowed.
Revised 6/15/2017 Contract No. 6001-20OL Page 68 of 148
The potential claim shall include the following certification relative to the California False Claims
Act, Government Code Sections 12650-12655. “The undersigned certifies that the above statements are made in full cognizance of the California
False Claims Act, Government Code Sections 12650-12655. The undersigned further understands and agrees that this potential claim, unless resolved, must be restated as a claim in response to the City’s proposed final estimate in order for it to be further considered.” By: Title: Date: Company Name: The Contractor’s estimate of costs may be updated when actual costs are known. The Contractor shall submit substantiation of its actual costs to the Engineer within 20 working days after the affected work is completed. Failure to do so shall be sufficient cause for denial of any claim subsequently filed on the basis of said notice of potential claim.
It is the intention of this section that differences between the parties arising under and by virtue of the contract be brought to the attention of the Engineer at the earliest possible time in order
that such matters be settled, if possible, or other appropriate action promptly taken. 3-5 DISPUTED WORK. The Contractor shall give the agency written notice of potential claim
prior to commencing any disputed work. Failure to give said notice shall constitute a waiver of all claims in connection therewith. If the contractor and the agency are unable to reach agreement on disputed work, the Agency may direct the contractor to proceed with the work. Prior to proceeding with dispute resolution pursuant to Public Contract Code provisions specified hereinafter, the contractor shall attempt to resolve all disputes informally through the following
dispute resolution chain of command:
1. Project Inspector 2. Construction Manager 3. Deputy City Engineer, Construction Management & Inspection 4. City Engineer 5. City Manager
The Contractor shall submit a complete report within 20 working days after completion of the disputed work stating its position on the claim, the contractual basis for the claim, along with all documentation supporting the costs and all other evidentiary materials. At each level of claim or appeal of claim the City will, within 10 working days of receipt of said claim or appeal of claim, review the Contractor’s report and respond with a position, request additional information or request that the Contractor meet and present its report. When additional information or a meeting is requested the City will provide its position within 10 working days of receipt of said additional information or Contractor’s presentation of its report. The Contractor may appeal each level’s position up to the City Manager after which the Contractor may proceed under the provisions of the Public Contract Code.

Quality of work shall be in accordance with the generally accepted standards. Material and work quality shall be subject to the Engineer’s approval. Materials and work quality not conforming to the requirements of the Specifications shall be considered defective and will be subject to rejection. Defective work or material, whether in place or not, shall be removed immediately from the site by the Contractor, at its expense, when so directed by the Engineer. If the Contractor fails to replace any defective or damaged work or material after reasonable
notice, the Engineer may cause such work or materials to be replaced. The replacement expense will be deducted from the amount to be paid to the Contractor.
Used or secondhand materials, parts, and equipment may be used only if permitted by the Specifications. 4-1.2 Protection of Work and Materials. The Contractor shall provide and maintain storage facilities and employ such measures as will preserve the specified quality and fitness of materials to be used in the Work. Stored materials shall be reasonably accessible for inspection. The Contractor shall also adequately protect new and existing work and all items of equipment for the duration of the Contract. The Contractor shall not, without the Agency’s consent, assign, sell, mortgage, hypothecate, or remove equipment or materials which have been installed or delivered and which may be necessary for the completion of the Contract. 4-1.3 Inspection Requirements.
4-1.3.1 General. Unless otherwise specified, inspection is required at the source for such typical materials and fabricated items as bituminous paving mixtures, structural concrete, metal
fabrication, metal casting, welding, concrete pipe manufacture, protective coating application, and similar shop or plant operations.
Steel pipe in sizes less than 18 inches and vitrified clay and cast iron pipe in all sizes are acceptable upon certification as to compliance with the Specifications, subject to sampling and testing by the Agency. Standard items of equipment such as electric motors, conveyors, elevators, plumbing fixtures, etc., are subject to inspection at the job site only. Special items of equipment such as designed electrical panel boards, large pumps, sewage plant equipment, etc., are subject to inspection at the source, normally only for performance testing. The Specifications may require inspection at the source for other items not typical of those listed in this section. The Contractor shall provide the Engineer free and safe access to any and all parts of work at any time. Such free and safe access shall include means of safe access and egress, ventilation, lighting, shoring, dewatering and all elements pertaining to the safety of persons as contained in
Revised 6/15/2017 Contract No. 6001-20OL Page 75 of 148
the State of California, California Code of Regulations, Title 8, Industrial Relations, Chapter 4, Division of Industrial Safety, Subchapter 4, Construction Safety Orders and such other safety
regulations as may apply. Contractor shall furnish Engineer with such information as may be necessary to keep the Engineer fully informed regarding progress and manner of work and character of materials. Inspection or testing of the whole or any portion of the work or materials
incorporated in the work shall not relieve Contractor from any obligation to fulfill this Contract. 4-1.3.2 Inspection of Materials Not Locally Produced. When the Contractor intends to purchase materials, fabricated products, or equipment from sources located more than 50 miles outside the geographical limits of the Agency, an inspector or accredited testing laboratory (approved by the Engineer), shall be engaged by the Contractor at its expense, to inspect the materials, equipment or process. This approval shall be obtained before producing any material or equipment. The inspector or representative of the testing laboratory shall judge the materials by the requirements of the Plans and Specifications. The Contractor shall forward reports required by the Engineer. No material or equipment shall be shipped nor shall any processing, fabrication or treatment of such materials be done without proper inspection by the approved agent. Approval
by said agent shall not relieve the Contractor of responsibility for complying with the Contract requirements. 4-1.3.3 Inspection by the Agency. The Agency will provide all inspection and testing laboratory services within 50 miles of the geographical limits of the Agency. For private contracts, all costs of inspection at the source, including salaries and mileage costs, shall be paid by the permittee.
4-1.4 Test of Material. Before incorporation in the Work, the Contractor shall submit samples of materials, as the Engineer may require, at no cost to the Agency. The Contractor, at its expense, shall deliver the materials for testing to the place and at the time designated by the Engineer. Unless otherwise provided, all initial testing will be performed under the direction of the Engineer, and at no expense to the Contractor. If the Contractor is to provide and pay for testing, it will be stated in the Specifications. For private contracts, the testing expense shall be borne by the permittee. The Contractor shall notify the Engineer in writing, at least 15 days in advance, of its intention to use materials for which tests are specified, to allow sufficient time to perform the tests. The notice
shall name the proposed supplier and source of material. If the notice of intent to use is sent before the materials are available for testing or inspection or
is sent so far in advance that the materials on hand at the time will not last but will be replaced by a new lot prior to use on the Work, it will be the Contractor’s responsibility to renotify the Engineer when samples which are representative may be obtained.
Except as specified in these Provisions, the Agency will bear the cost of testing of locally produced materials and/or on-site workmanship where the results of such tests meet or exceed the requirements indicated in the Standard Specifications, Technical Specification, and any Supplemental Provisions. The cost of all other tests shall be borne by the Contractor. At the option of the Engineer, the source of supply of each of the materials shall be approved by the Engineer before the delivery is started. All materials proposed for use may be inspected or tested at any time during their preparation and use. If, after incorporating such materials into the Work, it is found that sources of supply that have been approved do not furnish a uniform product, or if the product from any source proves unacceptable at any time, the Contractor shall furnish
approved material from other approved sources. If any product proves unacceptable after
Revised 6/15/2017 Contract No. 6001-20OL Page 76 of 148
improper storage, handling or for any other reason it shall be rejected, not incorporated into the work and shall be removed from the project site all at the Contractor’s expense.
Compaction or any tests may be made by the Engineer and all costs for tests that meet or exceed the requirements of the specifications shall be borne by the Agency. Said tests may be made at
any place along the work as deemed necessary by the Engineer. The costs of any retests made necessary by noncompliance with the specifications shall be borne by the Contractor.
If the Contractor chooses to dispute the Agency’s test results, the Contractor shall conduct
additional testing of their own, at no additional cost to the Agency. The additional testing shall be done by a third-party certified testing lab agreed upon by the Agency and the Contractor, and at project locations selected by the Agency. Testing and sampling shall be conducted in the presence of the Engineer or designee.
4-1.5 Certification. The Engineer may waive materials testing requirements of the Specifications and accept the manufacturer’s written certification that the materials to be supplied meet those requirements. Material test data may be required as part of the certification.
4-1.6 Trade Names or Equals. The Contractor may supply any of the materials specified or offer an equivalent. The Engineer shall determine whether the material offered is equivalent to that specified. Adequate time shall be allowed for the Engineer to make this determination.
Whenever any particular material, process, or equipment is indicated by patent, proprietary or brand name, or by name of manufacturer, such wording is used for the purpose of facilitating its
description and shall be deemed to be followed by the words or equal. A listing of materials is not intended to be comprehensive, or in order of preference. The Contractor may offer any material, process, or equipment considered to be equivalent to that indicated. The substantiation
of offers shall be submitted as provided in the contract documents. If the Contractor wishes to use any different products, materials or methods other than those specified in this contract, the Contractor shall submit those in a Request for Information (RFI) form for consideration by the City during the advertisement period only. If the Contractor wishes to use any different products, materials or methods after the contract has been awarded, the City has sole discretion whether to consider them. The Contractor shall, at its expense, furnish data concerning items offered by it as equivalent to those specified. The Contractor shall have the
material tested as required by the Engineer to determine that the quality, strength, physical, chemical, or other characteristics, including durability, finish, efficiency, dimensions, service, and suitability are such that the item will fulfill its intended function.
Test methods shall be subject to the approval of the Engineer. Test results shall be reported promptly to the Engineer, who will evaluate the results and determine if the substitute item is
equivalent. The Engineer’s findings shall be final. Installation and use of a substitute item shall not be made until approved by the Engineer. If a substitute offered by the Contractor is not found to be equal to the specified material, the Contractor shall furnish and install the specified material. The specified Contract completion time shall not be affected by any circumstance developing from the provisions of this section.
Revised 6/15/2017 Contract No. 6001-20OL Page 77 of 148
The Contractor is responsible for the satisfactory performance of substituted items. If, in the sole opinion of the Engineer, the substitution is determined to be unsatisfactory in performance,
appearance, durability, compatibility with associated items, availability of repair parts and suitability of application the Contractor shall remove the substituted item and replace it with the originally specified item at no cost to the Agency.
4-1.7 Weighing and Metering Equipment. All scales and metering equipment used for proportioning materials shall be inspected for accuracy and certified within the past 12 months by the State of California Bureau of Weights and Measures, by the County Director or Sealer of Weights and Measures, or by a scale mechanic registered with or licensed by the County. The accuracy of the work of a scale service agency, except as stated herein, shall meet the standards of the California Business and Professions Code and the California Code of Regulations pertaining to weighing devices. A certificate of compliance shall be presented, prior to operation, to the Engineer for approval and shall be renewed whenever required by the Engineer at no cost to the Agency.
All scales shall be arranged so they may be read easily from the operator’s platform or area. They shall indicate the true net weight without the application of any factor. The figures of the scales
shall be clearly legible. Scales shall be accurate to within 1 percent when tested with the plant shut down. Weighing equipment shall be so insulated against vibration or moving of other operating equipment in the plant area that the error in weighing with the entire plant running will
not exceed 2 percent for any setting nor 1.5 percent for any batch. 4-1.8 Calibration of Testing Equipment. Testing equipment, such as, but not limited to pressure gages, metering devices, hydraulic systems, force (load) measuring instruments, and strain-measuring devices shall be calibrated by a testing agency acceptable to the Engineer at intervals not to exceed 12 months and following repairs, modification, or relocation of the equipment. Calibration certificates shall be provided when requested by the Engineer. 4-1.9 Construction Materials Dispute Resolution (Soils, Rock Materials, Concrete, Mortar and Related Materials, Masonry Materials, Bituminous Materials, Rock Products, and Modified Asphalts). In the interest of safety and public value, whenever credible evidence arises
to contradict the test values of materials, the Agency and the Contractor will initiate an immediate and cooperative investigation. Test values of materials are results of the materials’ tests, as defined by these Specifications or by the special provisions, required to accept the Work. Credible
evidence is process observations or test values gathered using industry accepted practices. A contradiction exists whenever test values or process observations of the same or similar materials are diverse enough such that the work acceptance or performance becomes suspect. The
investigation shall allow access to all test results, procedures, and facilities relevant to the disputed work and consider all available information and, when necessary, gather new and additional information in an attempt to determine the validity, the cause, and if necessary, the remedy to the contradiction. If the cooperative investigation reaches any resolution mechanism acceptable to both the Agency and the Contractor, the contradiction shall be considered resolved and the cooperative investigation concluded. Whenever the cooperative investigation is unable to reach resolution, the investigation may then either conclude without resolution or continue by written notification of one party to the other requesting the implementation of a resolution process by committee. The continuance of the investigation shall be contingent upon recipient’s agreement and acknowledged in writing within 3 calendar days after receiving a request. Without acknowledgement, the investigation shall conclude without resolution. The committee shall
consist of three State of California Registered Civil Engineers. Within 7 calendar days after the
Revised 6/15/2017 Contract No. 6001-20OL Page 78 of 148
written request notification, the Agency and the Contractor will each select one engineer. Within 14 calendar days of the written request notification, the two selected engineers will select a third
engineer. The goal in selection of the third member is to complement the professional experience of the first two engineers. Should the two engineers fail to select the third engineer, the Agency and the Contractor shall each propose 2 engineers to be the third member within 21 calendar
days after the written request notification. The first two engineers previously selected shall then select one of the four proposed engineers in a blind draw. The committee shall be a continuance of the cooperative investigation and will re-consider all available information and if necessary gather new and additional information to determine the validity, the cause, and if necessary, the remedy to the contradiction. The committee will focus upon the performance adequacy of the material(s) using standard engineering principles and practices and to ensure public value, the committee may provide engineering recommendations as necessary. Unless otherwise agreed, the committee will have 30 calendar days from its formation to complete their review and submit their findings. The final resolution of the committee shall be by majority opinion, in writing, stamped and signed. Should the final resolution not be unanimous, the dissenter may attach a written, stamped, and signed minority opinion. Once started, the resolution process by committee shall
continue to full conclusion unless: 1. Within 7 days of the formation of the committee, the Agency and the Contractor reach an
acceptable resolution mechanism; or
2. Within 14 days of the formation of the committee, the initiating party withdraws its written notification and agrees to bear all investigative related costs thus far incurred; or
3. At any point by the mutual agreement of the Agency and the Contractor. Unless otherwise agreed, the Contractor shall bear and maintain a record for all the investigative costs until resolution. Should the investigation discover assignable causes for the contradiction, the
assignable party, the Agency or the Contractor, shall bear all costs associated with the investigation. Should assignable causes for the contradiction extended to both parties, the investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation substantiate a contradiction without assignable cause, the investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation be unable to substantiate a contradiction, the initiator of the investigation shall bear all investigative costs. All claim notification requirements of the contract pertaining to the contradiction shall be suspended until the investigation is concluded. 4-2 MATERIALS TRANSPORTATION, HANDLING AND STORAGE. The Contractor
shall order, purchase, transport, coordinate delivery, accept delivery, confirm the quantity and
quality received, prepare storage area(s), store, handle, protect, move, relocate, remove and dispose excess of all materials used to accomplish the Work. Materials shall be delivered to the site of the work only during working hours, as defined in Section 6-7.2, and shall be accompanied by bills of lading that shall clearly state for each delivery: the name of the Contractor as consignee, the project name and number, address of delivery and name of consignor and a description of the material(s) shipped. Prior to storage of any materials which have been shipped to or by the Contractor to any location within the Agency’s boundaries the Contractor shall provide the Engineer a copy of lease agreements for each property where such materials are stored. The lease agreement shall clearly state the term of the lease, the description of materials allowed to be stored and shall provide for the removal of the materials and restoration of the storage site within the time allowed for the Work. All such storage shall conform to all laws and ordinances
that may pertain to the materials stored and to preparation of the storage site and the location of the site on which the materials are stored. Loss, damage or deterioration of all stored materials
Revised 6/15/2017 Contract No. 6001-20OL Page 79 of 148
shall be the Contractor’s responsibility. Conformance to the requirements of this section, both within and outside the limits of work are a part of the Work. The Engineer shall have the right to
verify the suitability of materials and their proper storage at any time during the Work.
Revised 6/15/2017 Contract No. 6001-20OL Page 80 of 148
SECTION 5 – UTILITIES
5-1 LOCATION. The Agency and affected utility companies have, by a search of known records, endeavored to locate and indicate on the Plans, all utilities which exist within the limits
of the work. However, the accuracy and/or completeness of the nature, size and/or location of utilities indicated on the Plans is not guaranteed. Where underground main distribution conduits such as water, gas, sewer, electric power, telephone, or cable television are shown on the Plans, the Contractor shall assume that every property parcel will be served by a service connection for each type of utility. As provided in Section 4216 of the California Government Code, at least 2 working days prior to commencing any excavation, the Contractor shall contact the regional notification center (Underground Service Alert of Southern California) and obtain an inquiry identification number.
The California Department of Transportation is not required by Section 4216 to become a member of the regional notification center. The Contractor shall contact it for location of its subsurface installations.
The Contractor shall determine the location and depth of all utilities, including service connections, which have been marked by the respective owners and which may affect or be affected by its
operations. If no pay item is provided in the Contract for this work, full compensation for such work shall be considered as included in the prices bid for other items of work. 5-2 PROTECTION. The Contractor shall not interrupt the service function or disturb the support of any utility without authority from the owner or order from the Agency. All valves, switches, vaults, and meters shall be maintained readily accessible for emergency shutoff.
Where protection is required to ensure support of utilities located as shown on the Plans or in accordance with Section 5-1, the Contractor shall, unless otherwise provided, furnish and place
the necessary protection at its expense. Upon learning of the existence and location of any utility omitted from or shown incorrectly on the Plans, the Contractor shall immediately notify the Engineer in writing. When authorized by the Engineer, support or protection of the utility will be paid for as provided in Section 3-2.2.3 or 3-3. The Contractor shall immediately notify the Engineer and the utility owner if any utility is disturbed or damaged. The Contractor shall bear the costs of repair or replacement of any utility damaged if located as noted in Section 5-1. When placing concrete around or contiguous to any non-metallic utility installation, the Contractor
shall at its expense:
1. Furnish and install a 2 inch cushion of expansion joint material or other similar resilient material; or
2. Provide a sleeve or other opening which will result in a 2 inch minimum-clear annular space between the concrete and the utility; or 3. Provide other acceptable means to prevent embedment in or bonding to the concrete.
Revised 6/15/2017 Contract No. 6001-20OL Page 81 of 148
Where concrete is used for backfill or for structures which would result in embedment, or partial embedment, of a metallic utility installation; or where the coating, bedding or other cathodic
protection system is exposed or damaged by the Contractor’s operations, the Contractor shall notify the Engineer and arrange to secure the advice of the affected utility owner regarding the procedures required to maintain or restore the integrity of the system.
5-3 REMOVAL. Unless otherwise specified, the Contractor shall remove all interfering portions of utilities shown on the Plans or indicated in the Bid documents as “abandoned” or “to
be abandoned in place”. Before starting removal operations, the Contractor shall ascertain from the Agency whether the abandonment is complete, and the costs involved in the removal and disposal shall be included in the Bid for the items of work necessitating such removals.
5-4 RELOCATION. When feasible, the owners responsible for utilities within the area affected by the Work will complete their necessary installations, relocations, repairs, or
replacements before commencement of work by the Contractor. When the Plans or Specifications indicate that a utility installation is to be relocated, altered, or constructed by others, the Agency will conduct all negotiations with the owners and work will be done at no cost to the Contractor, except for manhole frame and cover sets to be brought to grade as provided in the Standard Specifications for Public Works Construction, Section 301-1.6, 2012 Edition, and the supplements thereto. Utilities which are relocated in order to avoid interference shall be protected in their
position and the cost of such protection shall be included in the Bid for the items of work necessitating such relocation.
After award of the Contract, portions of utilities which are found to interfere with the Work will be relocated, altered or reconstructed by the owners, or the Engineer may order changes in the Work to avoid interference. Such changes will be paid for in accordance with Section 3-2.
When the Plans or Specifications provide for the Contractor to alter, relocate, or reconstruct a utility, all costs for such work shall be included in the Bid for the items of work necessitating such work. Temporary or permanent relocation or alteration of utilities requested by the Contractor for its convenience shall be its responsibility and it shall make all arrangements and bear all costs. The utility owner will relocate service connections as necessary within the limits of the Work or within temporary construction or slope easements. When directed by the Engineer, the Contractor shall arrange for the relocation of service connections as necessary between the meter and property line, or between a meter and the limits of temporary construction or slope easements. The relocation of such service connections will be paid for in accordance with provisions of
Section 3-3. Payment will include the restoration of all existing improvements which may be affected thereby. The Contractor may agree with the owner of any utility to disconnect and reconnect interfering service connections. The Agency will not be involved in any such agreement. In conformance with Section 5-6 the Contractor shall coordinate the work with utility agencies and companies. Prior to the installation of any and all utility structures within the limits of work by any
utility agency or company, or its contractor, the Contractor shall place all curb or curb and gutter that is a part of the work and adjacent to the location where such utility structures are shown on the plans and are noted as being located, relocated or are otherwise shown as installed by others. In order to minimize delays to the Contractor caused by the failure of other parties to relocate utilities that interfere with the construction, the Contractor, upon the Engineer’s approval, may be permitted to temporarily omit the portion of work affected by the utility. If such temporary omission is approved by the Engineer the Contractor shall place survey or other physical control markers sufficient to locate the curb or curb and gutter to the satisfaction of the utility agency or company.
Revised 6/15/2017 Contract No. 6001-20OL Page 82 of 148
Such temporary omission shall be for the Contractor’s convenience and no additional compensation will be allowed therefore or for additional work, materials or delay associated with
the temporary omission. The portion thus omitted shall be constructed by the Contractor immediately following the relocation of the utility involved unless otherwise directed by the Engineer.
5-5 DELAYS. The Contractor shall notify the Engineer of its construction schedule insofar as it affects the protection, removal, or relocation of utilities. Said notification shall be included as a
part of the construction schedule required in Section 6-1. The Contractor shall notify the Engineer in writing of any subsequent changes in the construction schedule which will affect the time available for protection, removal, or relocation of utilities.
The Contractor will not be entitled to damages or additional payment for delays attributable to utility relocations or alterations if correctly located, noted, and completed in accordance with
Section 5-1. The Contractor may be given an extension of time for unforeseen delays attributable to
unreasonably protracted interference by utilities in performing work correctly shown on the Plans. The Agency will assume responsibility for the timely removal, relocation, or protection of existing main or trunkline utility facilities within the area affected by the Work if such utilities are not identified in the Contract Documents. The Contractor will not be assessed liquidated damages for any delay caused by failure of Agency to provide for the timely removal, relocation, or protection of such existing facilities.
If the Contractor sustains loss due to delays attributable to interferences, relocations, or alterations not covered by Section 5-1, which could not have been avoided by the judicious handling of forces, equipment, or plant, there shall be paid to the Contractor such amount as the
Engineer may find to be fair and reasonable compensation for such part of the Contractor’s actual loss as was unavoidable and the Contractor may be granted an extension of time. 5-6 COOPERATION. When necessary, the Contractor shall so conduct its operations as to permit access to the Work site and provide time for utility work to be accomplished during the progress of the Work.
Revised 6/15/2017 Contract No. 6001-20OL Page 83 of 148
SECTION 6 – PROSECUTION, PROGRESS AND ACCEPTANCE OF THE WORK
6-1 CONSTRUCTION SCHEDULE AND COMMENCEMENT OF WORK. Except as otherwise provided herein and unless otherwise prohibited by permits from other agencies as may
be required by law the Contractor shall begin work within seven (7) calendar days after receipt of the "Notice to Proceed". 6-1.1 Preconstruction Meeting. After, or upon, notification of contract award, the Engineer will set the time and location for the Preconstruction Meeting. Attendance of the Contractor’s management personnel responsible for the management, administration, and execution of the
project is mandatory for the meeting to be convened. Failure of the Contractor to have the Contractor’s responsible project personnel attend the Preconstruction Meeting will be grounds for default by Contractor per Section 6-4. No separate payment will be made for the Contractor’s attendance at the meeting. The notice to proceed will only be issued on or after the completion of the Preconstruction Meeting. A technical representative for the Warm Mix Asphalt (WMA) additive technology must attend the Preconstruction Meeting.
6-1.1.1 Baseline Construction Schedule Submittal. The Contractor shall submit the Baseline Construction Schedule per the submittal requirements of Section 2-5.3. The submittal of the
Baseline Construction Schedule shall include each item and element of Sections 6-1.2 through 6-1.2.9 and shall be on hard (paper) copy and electronic media conforming to Section 6-1.3.3 Electronic Media. 6-1.2 Preparation and Review of the Baseline Construction Schedule. The Contractor shall prepare the Baseline Construction Schedule as a Critical Path Method (CPM) Schedule in the precedence diagram method (activity-on-node) format. The Baseline Construction Schedule shall depict a workable plan showing the sequence, duration, and interdependence of all activities required to represent the complete performance of all project work as well as periods where work is precluded. The Baseline Construction Schedule shall begin with the projected date of issuance of the notice to proceed and conclude with the date of final completion per the contract duration. The Baseline Construction Schedule shall include detail of all project phasing, staging, and sequencing, including all milestones necessary to define beginning and ending of each phase or stage.
6-1.2.1 Time-Scaled Network Diagram. As a part of the Baseline Construction Schedule the Contractor shall prepare and submit to the Engineer a complete time-scaled network diagram
showing all of the activities, logic relationships, and milestones comprising the schedule. 6-1.2.2 Tabular Listing. As a part of the Baseline Construction Schedule the Contractor shall
prepare and submit to the Engineer a tabular listing of all of the activities, showing for each activity the identification number, the description, the duration, the early start, the early finish, the late start, the late finish, the total float, and all predecessor and successor activities for the activity described. 6-1.2.3 Bar Chart. As a part of the Baseline Construction Schedule the Contractor shall prepare and submit to the Engineer a chart showing individual tasks and their durations arranged with the
Revised 6/15/2017 Contract No. 6001-20OL Page 84 of 148
tasks on the vertical axis and duration on the horizontal axis. The bar chart shall use differing texture patterns or distinctive line types to show the critical path. 6-1.2.5 Schedule Activities. Except for submittal activities, activity durations shall not be shorter than 1 working day nor longer than 15 working days, unless specifically and individually allowed
by the Engineer. The Baseline Construction Schedule shall include between 100 and 500 activities, including submittals, interfaces between utility companies and other agencies, project milestones and equipment and material deliveries. The number of activities will be sufficient, in the judgment of the Engineer, to communicate the Contractor’s plan for project execution, to accurately describe the project work, and to allow monitoring and evaluation of progress and of time impacts. Each activity’s description shall accurately define the work planned for the activity and each activity shall have recognizable beginning and end points. 6-1.2.6 Float. Float or slack time within the schedule is available without charge or compensation to whatever party or contingency first exhausts it.
6-1.2.7 Restraints to Activities. Any submittals, utility interfaces, or any furnishing of Agency supplied materials, equipment, or services, which may impact any activity’s construction shall be shown as a restraint to those activities. Time periods to accommodate the review and correction
of submittals shall be included in the schedule. 6-1.2.8 Late Completion. A Baseline Construction Schedule showing a project duration longer
than the specified contract duration will not be acceptable and will be grounds for determination of default by Contractor, per Section 6-4. 6-1.2.9 Early Completion. The Baseline Construction Schedule will show the Contractor’s plan to support and maintain the project for the entire contractual time span of the project. Should the Contractor propose a project duration shorter than contract duration, a complete Baseline Construction Schedule must be submitted, reflecting the shorter duration, in complete accordance with all schedule requirements of Section 6-1. The Engineer may choose to accept the Contractor’s proposal of a project duration shorter than the duration specified; provided the Agency is satisfied the shortened Baseline Construction Schedule is reasonable and the Agency and all other entities, public and private, which interface with the project are able to support the
provisions of the shortened Baseline Construction Schedule. The Agency’s acceptance of a shortened duration project will be confirmed through the execution of a contract change order revising the project duration and implementing all contractual requirements including liquidated
damages in accordance with the revised duration. 6-1.2.10 Engineer’s Review. The Construction Schedule is subject to the review of the Engineer.
The Engineer’s determination that the Baseline Construction Schedule proposed by the Contractor complies with the requirements of these supplemental provisions shall be a condition precedent to issuance of the Notice to Proceed by the Engineer. If the Engineer determines that the Construction Schedule does not meet the requirements of these specifications the Contractor shall correct the Construction Schedule to meet these specifications and resubmit it to the Engineer. Failure of the Contractor to obtain the Engineer’s determination that the initial Construction Schedule proposed by the Contractor complies with the requirements of these supplemental provisions within thirty (30) working days after the date of the Preconstruction Meeting shall be grounds for termination of the contract per Section 6-4. Days used by the Engineer to review the initial Construction Schedule will not be included in the 30 working days.
Revised 6/15/2017 Contract No. 6001-20OL Page 85 of 148
The Engineer will review and return to the Contractor, with any comments, the Baseline Construction Schedule within 15 working days of submittal. The Baseline Construction Schedule
will be returned marked as per Sections 6-1.2.10.1 through 6-1.2.10.3. 6-1.2.10.1 “Accepted.” The Contractor may proceed with the project work upon issuance of the
Notice to Proceed, and will receive payment for the schedule in accordance with Section 6-1.8.1. 6-1.2.10.2 “Accepted with Comments.” The Contractor may proceed with the project work upon issuance of the Notice to Proceed. The Contractor must resubmit the schedule incorporating the comments prior to receipt of payment per Section 6-1.8.1. 6-1.2.10.3 “Not Accepted.” The Contractor must resubmit the schedule incorporating the corrections and changes of the comments prior to receipt of payment per Section 6-1.8.1. The Notice to Proceed will not be issued by the Engineer if the changes of the comments are not submitted as required hereinbefore and marked “Accepted” or “Accepted with Comments” by the Engineer. The Contractor, at the sole option of the Engineer, may be considered as having
defaulted the contract under the provisions of Section 6-4 DEFAULT BY CONTRACTOR if the changes of the comments are not submitted as required hereinbefore and marked “Accepted” by the Engineer.
6-1.3 Preparation of Schedule Updates and Revisions. The Contractor shall meet with the Engineer during the last week of each month to agree upon each activity’s schedule status and
shall submit monthly updates of the Baseline Construction Schedule confirming the agreements no later than the fifth working day of the following month. The monthly update will be submitted on hard (paper) copy and electronic media conforming to Section 6-1.3.3 Electronic Media per the submittal requirements of Section 2-5.3 and will include each item and element of Sections 6-1.2 through 6-1.2.9 and 6-1.3.1 through 6-1.3.7. 6-1.3.1 Actual Activity Dates. The actual dates each activity was started and/or completed during the month. After first reporting an actual date, the Contractor shall not change that actual date in later updates without specific notification to the Engineer with the update. 6-1.3.2 Activity Percent Complete. For each activity underway at the end of the month, the
Contractor shall report the percentage determined by the Engineer as complete for the activity. 6-1.3.3 Electronic Media. The schedule data disk shall be a CD-ROM, labeled with the project
name and number, the Contractor’s name and the date of preparation of the schedule data disk. The schedule data disk shall be readable by the software specified in Section 6-1.2.4 “Schedule Software” and shall be free of file locking, encryption or any other protocol that would impede full
access of all data stored on it. 6-1.3.4 List of Changes. A list of all changes made to the activities or to the interconnecting logic, with an explanation for each change. 6-1.3.5 Change Orders. Each monthly update will include the addition of the network revisions reflecting the change orders approved in the previous month. The network revisions will be as agreed upon during the review and acceptance of the Contractor’s change orders. 6-1.3.6 Bar Chart. Each monthly update will include a chart showing individual tasks and their durations arranged with the tasks on the vertical axis and duration on the horizontal axis. The bar
chart shall use differing texture patterns or distinctive line types to show the critical path.
Revised 6/15/2017 Contract No. 6001-20OL Page 86 of 148
6-1.4 Engineer’s Review of Updated Construction Schedule. The Engineer will review and
return the Updated Construction Schedule to the Contractor, with any comments, within 5 working days of submittal. The Updated Construction Schedule will be returned marked as per Sections 6-1.4.1 through 6-1.4.3. Any Updated Construction Schedule marked “Accepted with Comments”
or “Not Accepted” by the Engineer will be returned to the Contractor for correction. Upon resubmittal the Engineer will review and return the resubmitted Updated Construction Schedule to the Contractor, with any comments, within 5 working days. Failure of the Contractor to submit a monthly updated construction schedule will invoke the same consequences as the Engineer returning a monthly updated construction schedule marked “Not Accepted”. 6-1.4.1 “Accepted.” The Contractor may proceed with the project work and will receive payment for the schedule in accordance with Section 6-1.8.2. 6-1.4.2 “Accepted with Comments.” The Contractor may proceed with the project work. The Contractor must resubmit the Updated Construction Schedule to the Engineer incorporating the
corrections and changes noted in the Engineer’s comments prior to receipt of payment per Section 6-1.8.2. 6-1.4.3 “Not Accepted.” The Contractor must resubmit the Updated Construction Schedule to the Engineer incorporating the corrections and changes noted in the Engineer’s comments prior to receipt of payment per Section 6-1.8.2. The Contractor, at the sole option of the Engineer, may
be considered as having defaulted the contract under the provisions of Section 6-4 DEFAULT BY CONTRACTOR if the changes of the comments are not submitted and marked “Accepted” by the Engineer before the last day of the month in which the Updated Construction Schedule is due. If the Contractor fails to submit the corrected Updated Construction Schedule as required herein the Contractor may elect to proceed with the project at its own risk. Should the Contractor elect not to proceed with the project, any resulting delay, impact, or disruption to the project will be the Contractor’s responsibility. 6-1.5 Late Completion or Milestone Dates. Should the Schedule Update indicate a completion or contractually required milestone date later than the properly adjusted contract or milestone duration, the Agency may withhold Liquidated Damages for the number of days late. Should a
subsequent “Accepted” Schedule Update remove all or a portion of the delay, all or the allocated portion of the previously held Liquidated Damages shall be released in the monthly payment to the Contractor immediately following the “Accepted” schedule.
6-1.6 Interim Revisions. Should the actual or projected progress of the work become substantially different from that depicted in the Project Schedule, independently of and prior to the
next monthly update, the Contractor will submit a revised Baseline Construction Schedule, with a list and explanation of each change made to the schedule. The Revised Construction Schedule will be submitted per the submittal requirements of Section 2-5.3 and per the schedule review and acceptance requirements of Section 6-1, including but not limited to the acceptance and payment provisions. As used in this section “substantially different” means a time variance greater than 5 percent of the number of days of duration for the project. 6-1.7 Final Schedule Update. The Contractor shall prepare and submit a final schedule update when one hundred percent of the construction work is completed. The Contractor’s Final Schedule Update must accurately represent the actual dates for all activities. The final schedule update shall be prepared and reviewed per Sections 6-1.3 Preparation of Schedule Updates and
Revisions and 6-1. 4 Engineer’s Review of Updated Construction Schedule. Acceptance of the
Revised 6/15/2017 Contract No. 6001-20OL Page 87 of 148
final schedule update is required for completion of the project and release of any and all funds retained per Section 9-3.2.
6-1.8 Measurement and Payment of Construction Schedule. The Contractor’s preparation, revision and maintenance of the Construction Schedule are incidental to the work and no separate
payment will be made therefore. 6-2 PROSECUTION OF WORK. To minimize public inconvenience and possible hazard
and to restore street and other work areas to their original condition and state of usefulness as soon as practicable, the Contractor shall diligently prosecute the Work to completion. If the Engineer determines that the Contractor is failing to prosecute the Work to the proper extent, the
Contractor shall, upon orders from the Engineer, immediately take steps to remedy the situation. All costs of prosecuting the Work as described herein shall be included in the Contractor’s Bid. Should the Contractor fail to take the necessary steps to fully accomplish said purposes, after
orders of the Engineer, the Engineer may suspend the work in whole or part, until the Contractor takes said steps.
As soon as possible under the provisions of the Specifications, the Contractor shall backfill all excavations and restore to usefulness all improvements existing prior to the start of the Work. If Work is suspended through no fault of the Agency, all expenses and losses incurred by the Contractor during such suspensions shall be borne by the Contractor. If the Contractor fails to properly provide for public safety, traffic, and protection of the Work during periods of suspension, the Agency may elect to do so, and deduct the cost thereof from monies due the Contractor. Such actions will not relieve the Contractor from liability.
6-2.1 Order of Work. The work to be done shall consist of furnishing all labor, equipment and materials, and performing all operations necessary to complete the Project Work as shown on the
Project Plans and as specified in the Specifications. 6-2.3 Project Meetings. The Engineer will establish the time and location of Project Meetings whenever necessary. The Contractor’s Representative shall attend each Project Meeting. The Project Representative shall be the individual determined under Section 7-6, “The Contractor’s
Representative”. No separate payment for attendance of the Contractor, the Contractor’s Representative or any other employee or subcontractor or subcontractor’s employee at these meetings will be made.
6-3 SUSPENSION OF WORK. 6-3.1 General. The Work may be suspended in whole or in part when determined by the Engineer that the suspension is necessary in the interest of the Agency. The Contractor shall comply immediately with any written order of the Engineer. Such suspension shall be without
liability to the Contractor on the part of the Agency except as otherwise specified in Section 6-6.3. 6-3.2 Archaeological and Paleontological Discoveries. If discovery is made of items of archaeological or paleontological interest, the Contractor shall immediately cease excavation in the area of discovery and shall not continue until ordered by the Engineer. When resumed, excavation operations within the area of discovery shall be as directed by the Engineer.
Discoveries which may be encountered may include, but not be limited to, dwelling sites, stone implements or other artifacts, animal bones, human bones, and fossils.
Revised 6/15/2017 Contract No. 6001-20OL Page 88 of 148
The Contractor shall be entitled to an extension of time and compensation in accordance with the
provisions of Section 6-6. 6-4 DEFAULT BY CONTRACTOR. If the Contractor fails to begin delivery of material and
equipment, to commence the Work within the time specified, to maintain the rate of delivery of material, to execute the Work in the manner and at such locations as specified, or fails to maintain the Work schedule which will insure the Agency’s interest, or, if the Contractor is not carrying out
the intent of the Contract, the Agency may serve written notice upon the Contractor and the Surety on its Faithful Performance Bond demanding satisfactory compliance with the Contract.
The Contract may be canceled by the Board without liability for damage, when in the Board’s opinion the Contractor is not complying in good faith, has become insolvent, or has assigned or subcontracted any part of the Work without the Board’s consent. In the event of such cancellation,
the Contractor will be paid the actual amount due based on Contract Unit Prices or lump sums bid and the quantity of the Work completed at the time of cancellation, less damages caused to the Agency by acts of the Contractor. The Contractor, in having tendered a Bid, shall be deemed
to have waived any and all claims for damages because of cancellation of Contract for any such reason. If the Agency declares the Contract canceled for any of the above reasons, written notice to that effect shall be served upon the Surety. The Surety shall, within five (5) days, assume control and perform the Work as successor to the Contractor. If the Surety assumes any part of the Work, it shall take the Contractor’s place in all respects for that part and shall be paid by the Agency for all work performed by it in accordance with the Contract. If the Surety assumes the entire Contract, all money due the Contractor at the time of
its default shall be payable to the Surety as the Work progresses, subject to the terms of the Contract.
If the Surety does not assume control and perform the Work within 5 days after receiving notice of cancellation, or fails to continue to comply, the Agency may exclude the Surety from the premises. The Agency may then take possession of all material and equipment and complete the
Work by Agency forces, by letting the unfinished Work to another Contractor, or by a combination of such methods. In any event, the cost of completing the Work shall be charged against the Contractor and its Surety and may be deducted from any money due or becoming due from the Agency. If the sums due under the Contract are insufficient for completion, the Contractor or Surety shall pay to the Agency within 5 days after the completion, all costs in excess of the sums due. The provisions of this section shall be in addition to all other rights and remedies available to the Agency under law. 6-5 TERMINATION OF CONTRACT. The Board may terminate the Contract at its own
discretion or when conditions encountered during the Work make it impossible or impracticable
to proceed, or when the Agency is prevented from proceeding with the Contract by act of God, by law, or by official action of a public authority. 6-6 DELAYS AND EXTENSIONS OF TIME. 6-6.1 General. If delays are caused by unforeseen events beyond the control of the Contractor,
such delays will entitle the Contractor to an extension of time as provided herein, but the
Revised 6/15/2017 Contract No. 6001-20OL Page 89 of 148
Contractor will not be entitled to damages or additional payment due to such delays, except as provided in 6-6.3. Such unforeseen events may include: war, government regulations, labor
disputes, strikes, fires, floods, adverse weather or elements necessitating cessation of work, inability to obtain materials, labor or equipment, required extra work, or other specific events as may be further described in the Specifications.
No extension of time will be granted for a delay caused by the Contractor’s inability to obtain materials unless the Contractor furnishes to the Engineer documentary proof. The proof must be provided in a timely manner in accordance with the sequence of the Contractor’s operations and the approved construction schedule. If delays beyond the Contractor’s control are caused by events other than those mentioned above, the Engineer may deem an extension of time to be in the best interests of the Agency. The Contractor will not be entitled to damages or additional payment due to such delays, except as provided in Section 6-6.3.
If delays beyond the Contractor’s control are caused solely by action or inaction by the Agency, such delays will entitle the Contractor to an extension of time as provided in Section 6-6.2. 6-6.2 Extensions of Time. Extensions of time, when granted, will be based upon the effect of delays to the Work. They will not be granted for noncontrolling delays to minor portions of the Work unless it can be shown that such delays did or will delay the progress of the Work.
6-6.3 Payment for Delays to Contractor. The Contractor will be compensated for damages incurred due to delays for which the Agency is responsible. Such actual costs will be determined by the Engineer. The Agency will not be liable for damages which the Contractor could have avoided by any reasonable means, such as judicious handling of forces, equipment, or plant. The determination of what damages the Contractor could have avoided will be made by the Engineer. 6-6.4 Written Notice and Report. The Contractor shall provide written notice to the Engineer within two hours of the beginning of any period that the Contractor has placed any workers or equipment on standby for any reason that the Contractor has determined to be caused by the Agency or by any organization that the Agency may otherwise be obligated by. The Contractor
shall provide continuing daily written notice to the Engineer, each working day, throughout the duration of such period of delay. The initial and continuing written notices shall include the classification of each workman and supervisor and the make and model of each piece of
equipment placed on standby, the cumulative duration of the standby, the Contractor’s opinion of the cause of the delay and a cogent explanation of why the Contractor could not avoid the delay by reasonable means. Should the Contractor fail to provide the notice(s) required by this section
the Contractor agrees that no delay has occurred and that it will not submit any claim(s) therefore. 6-7 TIME OF COMPLETION.
6-7.1 General. The Contractor shall complete the Work within the time set forth in the Contract. The Contractor shall complete each portion of the Work within such time as set forth in the Contract for such portion. The time of completion of the Contract shall be expressed working days. The Contractor shall diligently prosecute the work to completion within seventy (70) working days after the starting date specified in the Notice to Proceed.
Revised 6/15/2017 Contract No. 6001-20OL Page 90 of 148
6-7.2 Working Day. A working day is any day within the period between the start of the Contract time as defined in Section 6-1 and the date provided for completion, or upon field acceptance by
the Engineer for all work provided for in the Contract, whichever occurs first, other than: 1. Saturday,
2. Sunday, 3. any day designated as a holiday by the Agency, 4. any other day designated as a holiday in a Master Labor Agreement entered into by the Contractor or on behalf of the Contractor as an eligible member of a contractor association, 5. any day the Contractor is prevented from working at the beginning of the workday for cause as defined in Section 6-6.1, 6. any day the Contractor is prevented from working during the first 5 hours with at least 60 percent of the normal work force for cause as defined in Section 6-6.1. Unless superseded by the above paragraph or the approved Traffic Control Plan, the normal hours of work shall be between the hours of 8:30 a.m. and 3:30 p.m. on Mondays through Friday, excluding Agency holidays. The Contractor shall obtain the written approval of the Engineer if the Contractor desires to work outside said hours, night work, or at any time during weekends and/or holidays. This written permission must be obtained at least 48 hours prior to such work. The
Engineer may approve work outside the hours and/or days stated herein when, in his/her sole opinion, such work conducted by the Contractor is beneficial to the best interests of the Agency. The Contractor shall pay the inspection costs of such work. The Contractor shall submit a
schedule including a daily work plan to the Engineer reflecting the specified working hours and approved traffic control plan.
The Contractor shall incorporate the dates, areas and types of work prohibited in this section in the Construction Schedule required by Section 6.1. No additional payment, adjustment of bid prices or adjustment of contract time of completion will be allowed as a consequence of the prohibition of work being performed within the dates, areas and/or types of work prohibited in this section. 6-7.3 Contract Time Accounting. The Engineer will make a daily determination of each working day to be charged against the Contract time. These determinations will be discussed and the Contractor will be furnished a periodic statement showing allowable number of working days of Contract time, as adjusted, at the beginning of the reporting period. The statement will also indicate the number of working days charged during the reporting period and the number of
working days of Contract time remaining. If the Contractor does not agree with the statement, it shall file a written protest within 15 days after receipt, setting forth the facts of the protest. Otherwise, the statement will be deemed to have been accepted.
6-8 COMPLETION, ACCEPTANCE, AND WARRANTY. The Work will be inspected by the Engineer for acceptance upon receipt of the Contractor’s written assertion that the Work has been completed. The Engineer will not accept the Work or any portion of the Work before all of the Work is completed and all outstanding deficiencies that may exist are corrected by the Contractor and the Engineer is satisfied that all the materials and workmanship, and all other features of the Work, meet the requirements of all of the specifications for the Work. Use, temporary, interim or
permanent, of all, or portions of, the Work does not constitute acceptance of the Work. If, in the Engineer’s judgment, the Work has been completed and is ready for acceptance the Engineer will so certify to the Board. Upon such certification by the Engineer the Board may accept the
Revised 6/15/2017 Contract No. 6001-20OL Page 91 of 148
completed Work. Upon the Board’s acceptance of the Work the Engineer will cause a “Notice of Completion” to be filed in the office of the San Diego County Recorder. The date of recordation
shall be the date of completion of the Work. All work shall be warranted for one (1) year after recordation of the "Notice of Completion" and
any faulty work or materials discovered during the warranty period shall be repaired or replaced by the Contractor, at its expense. Twenty-five percent of the faithful performance bond shall be retained as a warranty bond for the one year warranty period. The Contractor shall replace or repair any such defective work in a manner satisfactory to the Engineer, after notice to do so from the Engineer, and within the time specified in the notice. If the Contractor fails to make such replacement or repairs within the time specified in the notice, the Agency may perform this work and the Contractor’s sureties shall be liable for the cost thereof. 6-9 LIQUIDATED DAMAGES. Failure of the Contractor to complete the Work within the
time allowed will result in damages being sustained by the Agency. For each consecutive calendar day in excess of the time specified for completion of Work, as adjusted in accordance with Section 6-6, the Contractor shall pay the Agency, or have withheld monies due it, the sum of one thousand
two hundred and fifty dollars ($1,250). Such sum is liquidated damages and shall not be construed as a penalty and may be deducted from payments due the Contractor if such delay occurs. Execution of the Contract shall constitute agreement by the Agency and Contractor that one thousand two hundred and fifty dollars ($1,250) per day is the minimum value of costs and actual damaged caused by the Contractor to complete the Work within the allotted time.

No compensation will be allowed for disposing of rejected or excess material. Payment for work performed or materials furnished under an Assessment Act Contract will be made as provided in particular proceedings or legislative act under which such contract was awarded. Whenever any portion of the Work is performed by the Agency at the Contractor’s request, the
cost thereof shall be charged against the Contractor, and may be deducted from any amount due or becoming due from the Agency.
Whenever immediate action is required to prevent injury, death, or property damage, and precautions which are the Contractor’s responsibility have not been taken and are not reasonably expected to be taken, the Agency may, after reasonable attempt to notify the Contractor, cause
such precautions to be taken and shall charge the cost thereof against the Contractor, or may deduct such cost from any amount due or becoming due from the Agency. Agency action or inaction under such circumstances shall not be construed as relieving the Contractor or its Surety from liability. Payment shall not relieve the Contractor from its obligations under the Contract; nor shall such payment be construed to be acceptance of any of the Work. Payment shall not be construed as the transfer of ownership of any equipment or materials to the Agency. Responsibility of ownership shall remain with the Contractor who shall be obligated to store any fully or partially completed work or structure for which payment has been made; or replace any materials or equipment required to be provided under the Contract which may be damaged, lost, stolen or
otherwise degraded in any way prior to acceptance of the Work, except as provided in Section 6-10.

If, within the time fixed by law, a properly executed notice to stop payment is filed with the Agency, due to the Contractor’s failure to pay for labor or materials used in the Work, all money due for such labor or materials will be withheld from payment to the Contractor in accordance with applicable laws. At the expiration of 35 days from the date of acceptance of the Work by the Board, or as prescribed by law, the amount deducted from the final estimate and retained by the Agency will be paid to the Contractor except such amounts as are required by law to be withheld by properly executed and filed notices to stop payment, or as may be authorized by the Contract to be further retained. 9-3.2 Partial and Final Payment. The Engineer will, after award of Contract, establish a closure
date for the purpose of making monthly progress payments. The Contractor may request in writing
Revised 6/15/2017 Contract No. 6001-20OL Page 106 of 148
that such monthly closure date be changed. The Engineer may approve such request when it is compatible with the Agency’s payment procedure.
Each month, the Engineer will make an approximate measurement of the work performed to the closure date as basis for making monthly progress payments. The estimated value will be based
on contract unit prices, completed change order work and as provided for in Section 9-2 of these General Provisions. Progress payments shall be made no later than thirty (30) calendar days after the closure date. Five (5) working days following the closure date, the Engineer shall complete the detailed progress pay estimate and submit it to the Contractor for the Contractor’s information. Should the Contractor assert that additional payment is due, the Contractor shall within ten (10) days of receipt of the progress estimate, submit a supplemental payment request to the Engineer with adequate justification supporting the amount of supplemental payment request. Upon receipt of the supplemental payment request, the Engineer shall, as soon as practicable after receipt, determine whether the supplemental payment request is a proper payment request. If the Engineer determines that the supplemental payment request is not proper, then the request shall be returned to the Contractor as soon as practicable, but not later than seven (7) days after
receipt. The returned request shall be accompanied by a document setting forth in writing the reasons why the supplemental payment request was not proper. In conformance with Public Contract Code Section 20104.50, the City shall make payments within thirty (30) days after receipt
of an undisputed and properly submitted supplemental payment request from the Contractor. If payment of the undisputed supplemental payment request is not made within thirty (30) days after receipt by the Engineer, then the City shall pay interest to the Contractor equivalent to the legal
rate set forth in subdivision (a) of Section 685.010 of the Code of Civil Procedure. From each progress estimate, 5 percent will be deducted and retained by the Agency, and the remainder less the amount of all previous payments will be paid. After 50 percent of the Work has been completed and if progress on the Work is satisfactory, the deduction to be made from remaining progress estimates and from the final estimate may be limited to $500 or 5 percent of the first half of total Contract amount, whichever is greater. No progress payment made to the Contractor or its sureties will constitute a waiver of the liquidated damages under 6-9.
As provided in Section 22300 of the California Public Contract Code, the Contractor may substitute securities for any monies withheld by the Agency to ensure performance under the Contract.
After final inspection, the Engineer will make a Final Payment Estimate and process a corresponding payment. This estimate will be in writing and shall be for the total amount owed the
Contractor as determined by the Engineer and shall be itemized by the contract bid item and change order item with quantities and payment amounts and shall show all deductions made or to be made for prior payments and amounts to be deducted under provisions of the contract. All prior estimates and progress payments shall be subject to correction in the Final Payment Estimate. The Contractor shall have 30 calendar days from receipt of the Final Payment Estimate to make written statement disputing any bid item or change order item quantity or payment amount. The Contractor shall provide all documentation at the time of submitting the statement supporting its position.

(Contractor’s License Number)
(Date)
As part of the City of Carlsbad’s ongoing program to maintain our roadways, streets in your neighborhood are scheduled for resurfacing in the coming weeks. The resurfacing work will
require traffic control to be put in place in those areas. The work will take place between the hours
of 8:30 a.m. and approximately 3:30 p.m., or until the traffic control devices are removed.
Residents located on the streets scheduled for resurfacing will be notified 72 hours in advance of
the work. Look for a brightly colored 3 ½” x 8 ½” card attached to your doorknob. You will also notice temporary “no parking” signs on your street with a specific “no parking” date written on it.
PLEASE NOTE: weather conditions and other factors outside our control can sometimes cause
work to be rescheduled at the last minute. If this happens, we will notify you as soon as possible
of the new date.
To prepare for this road work, we are asking neighbors to help. Here’s how:
• Park your car outside the area of work unless you plan to leave before 8 a.m. the morning
the work starts. Watch for “no parking” signs.
• Park your car in your driveway or garage (off the street) if you aren’t going to need it
between 8:30 a.m. and 3:30 p.m.
• Avoid walking, biking and skate boarding on new roads until construction signs are
removed.
• Please keep kids and pets off the new roadway on the day of the resurfacing.
• Do not walk on the newly resurfaced street or you may get black residue on the bottom of your shoes. The residue may damage or mark surfaces and be very difficult to remove.
• Please try to keep the work area and new road dry until construction signs are removed. Monitor sprinklers, hoses and other water sources around your home.
• Please note that mail could be delayed on the day of the resurfacing if your postal carrier cannot reach your mailbox.
• Work will be coordinated with trash pick-up.
• If you have a special concern or need reasonable accommodations, please call the City
of Carlsbad at 760-602-2780.
(Contractor Name) will be performing the resurfacing work for the city. You may call a contractor
representative at (XXX) XXX-XXXX for more information about the project and to answer questions. For a map of all streets scheduled for resurfacing throughout the city, please visit the

903-1.8 Production and Placement. 903-1.8.1 General. CIRACP operations shall neither start nor be performed during wet conditions, or if rain or cold conditions (less than 50°F) are forecast within a 48-hour period by the National Weather Service for the most representative and nearest location listed where the CIR is to begin
and end. The forecast ambient temperature shall be a minimum of 60°F and rising throughout the recycling operation until initial compaction and protection operations have been completed for that Day’s run. CIRACP operations shall cease if the actual ambient temperature drops below 60°F any time after an initial 3-hour window following start-up. CIRACP operations shall be completed at least 2 hours before sunset. CIRACP damaged by inclement weather shall be replaced by the Contractor at the Contractor’s expense as directed by the Engineer. The Contractor shall ensure that cold milling does not result in gaps of pavement which has not been recycled result along longitudinal edges nor in wedges created by the entry of the cold milling drum into the existing pavement. Longitudinal joints between successive cuts shall overlap a minimum of 4 inches.
903-1.8.2 Sequence of Work. The general sequence of work for production of CIRACP shall be as follows:
a) Surface Preparation. b) Milling, crushing, and sizing.
c) Mixing and proportioning. d) Spreading and initial compaction. e) Test Strip. f) Fog seal coat and sand cover. g) Curing and protection. h) Supplemental compaction. 903-1.8.3 Pre-Paving Conference. A minimum of 5 Working Days prior to the scheduled start of CIRACP placement and production, the Engineer will arrange a meeting with the Contractor’s Representative, the Contractor’s paving foreman, the CIRACP subcontractor, materials suppliers, and representatives of the Agency. The following will be discussed:
a) CIRACP placement plan. b) Equipment.
c) Rate of delivery/placement. d) Agency inspection. e) Traffic control.

Revised 6/15/2017 Contract No. 6001-20OL Page 142 of 148
903-1.8.5 Cold Milling, Crushing, and Screening. The RAP shall be processed to 1-inch maximum size and be free of dirt, base, concrete or other deleterious materials.
Residual materials that cannot be completely removed from the processed RAP may be incorporated into the recycled mix upon approval of the Engineer after demonstration by the
Contractor that such materials will not adversely affect the performance, appearance, or strength of the CIRACP. The existing pavement shall be cold milled to the depth shown on the Plans. 903-1.8.6 Mixing and Proportioning. Using a mass flow centrifugal type meter, the Contractor shall measure and weigh the emulsified recycling agent, and the cement or lime to be added into the RAP. The Contractor shall compare the amount of each additive against the amount reported in the approved CIRACP mix design or the adjusted amount approved by the Engineer. Each mixing and proportioning unit shall be calibrated in accordance with California Test 109. Water may be added by the milling machine to facilitate uniform mixing of the emulsified recycling agent and the RAP. Water added shall be measured and the rate of added water shall be between 0.5 and 5.0 percent of water added by weight of the recycled pavement mixture in accordance with
the approved CIRACP mix design. The quantity of residual asphalt in the recycling agent incorporated into the final recycled pavement mixture shall not vary due to the addition of water. 903-1.8.7 Mixing and Spreading Cement and Lime. 903-1.8.7.1 General. Proportioning of cement or lime slurry may be accomplished by either
continuous mixing or batch mixing. Cement or lime slurry may be added directly to the pugmill or may be sprayed over the cutting teeth of the milling machine at a rate specified in the approved CIRACP mix design. The Contractor shall provide the Engineer with daily batch logs. Dry cement may be spread upon the existing asphalt concrete surface ahead of the recycling train at the rate specified in the CIRACP mix design. If cement is spread ahead of the milling operation, the distance between the spreader and the recycling equipment shall be reduced as necessary to prevent being blown off the surface during windy days. In no case, shall additives be allowed to remain exposed at the end of the Day. No traffic other than the recycling equipment shall be allowed to pass over the spread additive until the recycling operation is complete. 903-1.8.7.2 Proportioning Cement or Lime Slurry. a) Continuous Mixing Proportioning. The proportioning device must determine the exact
ratio of water to dry lime or cement at each production rate. Rate-of-flow indicators and totalizers for like materials must be accurate within 0.5 percent of each other. The following method shall be used:
1) A belt scale shall be used to weigh cement or dry lime. When the belt scale operates between 30 percent and 100 percent of production capacity, the average difference between the indicated material weight and the actual material weight shall not exceed 0.5 percent of the actual material weight for 3 individual runs. For any of the 3 individual runs, the indicated material weight shall not vary from the actual material weight by more than one percent of the actual material weight. Tests for belt scale accuracy must be for at least 0.5 tons of cement or lime. Actual material mass shall be weighed on a certified scale. 2) A meter shall be used to measure water in the slurry. When the meter operates
between 50 percent and 100 percent of production capacity, the average difference
Revised 6/15/2017 Contract No. 6001-20OL Page 143 of 148
between the indicated water weight and the actual water weight shall not exceed one percent of the actual weight for 3 individual runs. Tests for water meter accuracy must
be for at least 300 gallons of water. Actual mass shall be weighed on a certified scale. 3) Meters and scales used shall be equipped with rate-of-flow indicators that show the
delivery rates of cement or lime and water and resettable totalizers that indicate the total amounts of cement or lime and water introduced into the slurry storage tank. Individual feeds for water and cement or lime shall be equipped with no-flow devices that stop slurry production when either of the individual ingredients is not being delivered to the slurry storage tank. b) Batch Mixing Proportioning. For batch-type proportioning for slurry production, the following method shall be used: 1) Cement or dry lime shall be weighed with a certified scale.
2) Water meter shall be equipped with a resettable totalizer. If an automatic controller is used to batch the cement or lime it shall also control the water proportioning. If an automatic controller is used to proportion the water the indicated draft of the water
must be within one percent of its total draft weight. The water meter shall be tested for accuracy at least as often as 300 gallons of water used.
3) When the meter operates between 50 percent and 100 percent of production capacity, the average difference between the indicated water weight and the actual water weight shall not exceed one percent of the actual water weight for 3 individual runs. 903-1.8.8 Spreading. The CIRACP mixture shall not be placed in a windrow, it shall be deposited directly into the hopper of the track paver or into a surge volume/remix material transfer vehicle (MTV). Immediately upon completion of the mixing and proportioning of the CIRACP mixture, the mixture shall be spread in one continuous pass without segregation to the lines and grades shown on the Plans. The wings of the track paver shall be emptied regularly to minimize segregation as well as to prevent buildup. Handwork of CIRACP shall be minimized while spreading. Based on the ambient temperatures, weather conditions, and type of emulsified recycling agent
used, the Contractor shall determine and record the time intervals between spreading and compacting of the CIRACP. The final time interval shall be recorded in the daily quality control documents. 903-1.9 Compaction. 903-1.9.1 General. Upon completion of the spreading operations, the CIRACP shall be graded and compacted to the depth, lines and grades shown on the Plans. Areas inaccessible to rollers shall be compacted to the required density by other equipment approved by the Engineer. 903-1.9.2 Initial Compaction and Initial In-Place Density. Initial compaction operations shall start no more than 15 minutes behind the track paver unless otherwise approved or directed by the Engineer. Compacting of the CIRACP shall follow the rolling pattern established on the test strip and verified by the Engineer.
Revised 6/15/2017 Contract No. 6001-20OL Page 144 of 148
Rolling shall be performed in a manner that results in starting and stopping taking place on previously compacted material.
The CIRACP mat shall be continuously observed during compaction. If moisture cracking occurs under the vibratory compaction mode, the vibrators shall be turned off and static rolling only
performed. If moisture cracking continues under static steel drum rolling, compaction shall cease, the mat allowed to further cure in order for additional moisture to escape, and pneumatic-tired rolling commenced, followed by steel drum rolling to iron out irregularities. This procedure shall be followed until there is no longer any displacement of the mat produced by rolling. The selected rolling pattern shall be followed unless changes in the CIRACP mixture or placement conditions occur and a new rolling pattern is established. Rolling that causes cracking, major displacement and/or any other type of pavement distress shall be discontinued until such time as the problem can be resolved. Discontinuation and commencement of rolling operations shall be at the discretion of the Engineer.
The Contractor shall ensure that aggregate from the CIRACP mixture does not stick to the drums or wheels of the rollers. Water shall be uniformly applied to the wheels and drums, along with mechanical means to keep aggregate from sticking. Sufficient water shall be applied to keep
rollers and tires clean, but not so much that water pools or ponds on the recycled surface. The final compacted surface of the CIRACP mixture shall be free of ruts, bumps, indentations,
raveling, irregularities, or segregation. The smoothness of the finished surface shall be checked regularly during placement using a 12-foot long straightedge. The smoothness shall not vary more than 3/8 inch from a 12-foot straightedge placed on the surface. Areas that vary from the lower edge by more than 0.01 foot when the straight edge is laid parallel with the centerline, or more than 0.02 foot when the straightedge is laid perpendicular to the centerline and extended from edge to edge of a traffic lane, shall be corrected by reworking, re-compaction, or removal and replacement. The correction method chosen by the Contractor must be approved by the Engineer before starting any corrective work. Corrected areas must be uniform rectangles with edges that are parallel to the nearest AC pavement edge or lane line; or perpendicular to the pavement centerline.
903-1.10 Test Strip. 903-1.10.1 General. A test strip of a single lane width and a minimum of 1,500 feet in length located within the limits of the CIRACP work shall be constructed on the first Working Day of CIRACP operations. The test strip section shall:
a) Demonstrate that the equipment, materials, processes, and proposed job mix formula (mix design) is capable of producing and constructing a CIRACP that conforms to the requirements of these Specifications; b) Establish the optimal rates for emulsified recycling agents, additives, and water recommended for the reclaimed asphalt pavement; c) Determine the effect on the CIRACP mixture at various forward speed rates, drum rotation rates of the cold milling or mixing equipment; and
Revised 6/15/2017 Contract No. 6001-20OL Page 145 of 148
d) Establish the sequence and manner of rolling necessary to achieve the maximum obtainable density using a compaction rolling pattern developed in the field by the
Contractor and reviewed by the Engineer. A rolling pattern for compaction shall be defined as that which produces no increase in density on successive nuclear density tests for any additional passes of the compaction equipment once the maximum density pattern has
been identified (“breakover point”). The Contractor shall prepare a rolling vs. density chart that shows the progress of densification from initial lay down through maximum obtainable density at the “break over point.” e) The Contractor shall determine relative compaction on the quantity within the test strip by nuclear gauge density (ASTM D2950). If the relative compaction within the test strip does not meet the density requirements, the Contractor shall construct additional test strips as necessary to determine the maximum density obtainable. Upon completion of the test strip, the Contractor shall provide a report to the Engineer with the following information:
f) Length, width, and depth of milling and calculated weight in tons of material processed.
g) Weight of emulsified recycling agent added in tons. h) Percentage of added emulsified recycling agent in the CIRACP mixture by weight.
i) Percentage of recycling additive in the CIRACP mixture by weight. j) Maximum particle size of the RAP before the addition of the emulsified recycling agent. k) Maximum obtainable density used for relative compaction calculation. l) Nuclear gauge in-place density and relative compaction at 10 random locations. m) A rolling vs. density chart that shows the progress of compaction from initial laydown through maximum obtainable density at the “break over point”.
n) Ambient and compacted recycled pavement surface temperatures.
o) Maximum theoretical density determined in accordance with California Test 309 and void ratio (Report Only). 903-10.2 Approval. CIRACP work shall proceed upon the approval of the test strip by the Engineer. Test strips that fail, or do not demonstrate or fulfill the requirements shall be re-worked, re-compacted, or removed and replaced. The Contractor shall determine the corrective actions to be taken, discuss the adjustments or changes with the Engineer, and obtain approval from the Engineer before proceeding. If adjustments are made, the Contractor shall construct a new test strip to define the maximum density. The Contractor shall use the same equipment, materials, and construction methods for the remainder of CIR operations, unless adjustments are made by the Contractor and approved by the Engineer.
Revised 6/15/2017 Contract No. 6001-20OL Page 146 of 148
903-1.11 Fog Seal Coat and Sand Cover. After initial compaction has been achieved, and prior to opening the CIRACP to traffic, the Contractor shall apply a fog seal coat to the CIRACP surface
which shall be composed of emulsified asphalt diluted with water at a ratio not to exceed 1:1 unless otherwise approved by the Engineer. The application rate of the fog seal coat shall be between 0.08 and 0.12 gallon per square yard. Immediately following application of the fog seal,
the CIRACP surface shall be covered with sand at a rate of 1.0 to 2.0 pounds per square yard. The exact rate will be determined by the Contractor. Excess sand shall be removed from the CIRACP surface by sweeping. The Contractor shall not start fog seal activities when precipitation is forecasted during the application and curing period. The Contractor shall cover drainage inlets and manholes during the application of seal coat, tack coat, slurry seal or fog seal. The Contractor shall submit a 1/2 gal sample of the emulsified asphalt in a plastic container. The Contractor shall take the sample from the distributor truck spray bar at midload. The Contractor shall apply the fog seal coat when the ambient air temperature is above 40°F.
The Contractor shall apply sand immediately after the emulsified asphalt application. Sand must comply with the material specifications for fine aggregate in accordance with section 200-1.5.3 of
the SSPWC. Sand must not include organic material or clay. 903-1.12 Curing, Protection, and Maintenance. CIRACP shall cure in-place until supplemental
compaction may commence as determined in accordance with the following: a) Prior to the start of cold milling, record the moisture content of the existing asphalt concrete
every 2,500 feet of each lane to be recycled using a nuclear gauge. Mark the adjacent
curb or shoulder where each reading was taken.
b) During recycling, calculate the percentage of hydrocarbons in the moisture content for
each location where a reading was taken by logging the percentage of engineered
emulsion used in the CIR mixture and subtracting out the percentage of water in the
engineered emulsion.
c) After a minimum of 3 Days without rainfall, record the moisture content of the CIRACP at
each marked location using the same nuclear gauge.
d) If the reading obtained in “c” above is less than the sum of the following, supplemental
compaction may commence:
• Moisture content percentage recorded in “a” above plus the percentage of
hydrocarbons in the moisture content determined in “b” above, plus 2 percent.
e) Supplemental compaction may commence after 10 Days without rainfall.
The Contractor shall protect and maintain the CIRACP free from nuisance water, other deleterious substances, and/or any other damage. Damaged areas shall be excavated to the depth directed
by the Engineer and/or filled and compacted with new C2-PG 64-10 asphalt concrete conforming to 203-6. Damaged areas shall be repaired and loose particles on the surface removed by sweeping prior to the placement of the asphalt concrete surface course or seal coat.
Revised 6/15/2017 Contract No. 6001-20OL Page 147 of 148
903-1.13 Supplemental Compaction. Supplemental compaction shall be conducted after the CIRACP has cured and prior to any smoothness testing or placement of a new asphalt concrete
surface course. The Contractor shall construct a test strip on the first Day of supplemental compaction operations.
The test strip shall be a single lane in width and at least 1,500 feet in length. The test strip must demonstrate the sequence and methods of rolling necessary to determine the maximum obtainable density. A rolling pattern for compaction shall be defined as that which produces no increase in density on successive nuclear density tests for any additional passes of the compaction equipment once the maximum density pattern has been identified (“break over point”). For each Lot, compaction testing at 10 random locations shall be conducted and the in-place density and relative compaction obtained. The relative compaction of the Lot using the average of the in-place density of the 10 locations and the maximum obtainable density from the supplemental compaction test strip shall be determined and recorded.
Relative compaction of each of the 10 individual locations shall be greater than or equal to 95 percent and less than or equal to 105 percent of the maximum obtainable density obtained in the test strip. Relative compaction of the Lot must be greater than or equal to 97 percent and less
than or equal to 103 percent of the maximum obtainable density obtained in the test strip. Nuclear density testing shall be repeated throughout the time final compaction is being completed to verify that the final compaction is being achieved. Care shall be taken not to over compact the CIRACP.
The Contractor’s qualified technician shall be on site and observing all final compaction efforts, monitoring density gauge readings, and approving areas as they reach maximum density. For each Lot, the Contractor shall measure or calculate and record the following information: a) Length and width. b) Maximum theoretical density used for compaction calculation. c) Nuclear gauge in-place density and relative compaction at 10 random locations.
d) Relative compaction for the Lot. e) Ambient temperature and surface temperature of compacted CIRACP.
f) Average in-place density and relative compaction.
If the relative compaction does not meet requirements, the Contractor shall construct additional test strips as necessary to determine the maximum obtainable density for the in-place CIRACP. The Contractor shall measure or calculate and record the following information: g) Length and width of CIR surface processed. h) Maximum obtainable density. i) Nuclear gauge in-place density and relative compaction at 10 random locations.
Revised 6/15/2017 Contract No. 6001-20OL Page 148 of 148
j) A rolling vs. density chart that shows the progress of densification from initial laydown through maximum obtainable density at the “break over point”.
k) Ambient and compacted recycled pavement surface temperatures.
Upon approval of the test strip by the Engineer, the supplemental compaction may begin. Compaction shall cease if the equipment and process fail to meet the requirements for a test strip. If the test strip fails, the Contractor shall re-work, re-compact, or remove and replace the test strip and discuss and document corrective actions to be taken with the Engineer before proceeding. 903-1.14 Measurement. CIRACP will be measured by the square yard of finished surface for each thickness shown on the Plans. CIRACP outside the limits shown on the Plans will not be measured for payment. Test strips conforming to the requirements of these Specifications will be included in the quantity measured for payment. Emulsified recycling agent will be measured by the ton. The quantity in the Bid is based on a
content of 3 percent. The basis of payment shall be the net weight of emulsified recycling agent used to produce CIRACP complete in-place. The Contractor shall furnish the Engineer with certified weighmaster certificates showing the weight of each load delivered to the Work site and
the weight remaining on the Work site after completion. Payment will be made for the difference between the weight delivered to the Work site and the weight of emulsified recycling agent remaining on the Work site after completion of CIRACP. The provisions of 3-2.2.2 and 3-2.2.3 of
