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
Contractor a penalty in an amount of not more than 10 percent of the subcontract involved, after
a public hearing.
Docusign Envelope ID: B14EDC88-8F56-8759-82FE-7A8A6097C802
Revised 6/12/18 Contract No. 5503-28 Page 24 of 96
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.
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.

Revised 6/12/18 Contract No. 5503-28 Page 25 of 96
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.

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
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.

Revised 6/12/18 Contract No. 5503-28 Page 36 of 96
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 6/12/18 Contract No. 5503-28 Page 37 of 96
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.
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.

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

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

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.

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.

hereinafter, the contractor shall attempt to resolve all disputes informally through the following
dispute resolution chain of command:

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
Docusign Envelope ID: B14EDC88-8F56-8759-82FE-7A8A6097C802

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 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.
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.
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.
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.
Docusign Envelope ID: B14EDC88-8F56-8759-82FE-7A8A6097C802
Revised 6/12/18 Contract No. 5503-28 Page 49 of 96
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
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
Docusign Envelope ID: B14EDC88-8F56-8759-82FE-7A8A6097C802
Revised 6/12/18 Contract No. 5503-28 Page 50 of 96
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
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.

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.
Docusign Envelope ID: B14EDC88-8F56-8759-82FE-7A8A6097C802
Revised 6/12/18 Contract No. 5503-28 Page 52 of 96
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. 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.
Such temporary omission shall be for the Contractor’s convenience and no additional
Docusign Envelope ID: B14EDC88-8F56-8759-82FE-7A8A6097C802
Revised 6/12/18 Contract No. 5503-28 Page 53 of 96
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. Cooperation with CMWD and City staff will be required for all work affecting
existing utility systems or facilities and prior to water utility shutdowns, sewer bypass operations,
testing and inspections, and project completion.

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 one (1) calendar day after receipt of the
"Notice to Proceed".
6-1.1 Pre-Construction 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.
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
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.
Docusign Envelope ID: B14EDC88-8F56-8759-82FE-7A8A6097C802
Revised 6/12/18 Contract No. 5503-28 Page 55 of 96
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.
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.

Revised 6/12/18 Contract No. 5503-28 Page 57 of 96
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
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.
6-3 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.
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
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.

Revised 6/12/18 Contract No. 5503-28 Page 60 of 96
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.

Contractor is beneficial to the best interests of the Agency. The Contractor shall pay the inspection
costs of such work.
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.
Contractor is hereby advised that the Engineer will possibly require after hours and weekend work
on an interim basis to accomplish the work.
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
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.

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. Liquidated Damages shall not be assessed by the Agency.
6-10 USE OF IMPROVEMENT DURING CONSTRUCTION. The Agency reserves the right to
take over and utilize all or part of any completed facility or appurtenance. The Contractor will be
notified in writing in advance of such action. Such action by the Agency will relieve the Contractor
of responsibility for injury or damage to said completed portions of the improvement resulting from
use by public traffic or from the action of the elements or from any other cause, except Contractor
operations or negligence. The Contractor will not be required to reclean such portions of the
improvement before field acceptance, except for cleanup made necessary by its operations.
Nothing in this section shall be construed as relieving the Contractor from full responsibility for
correcting defective work or materials.

completed facility or appurtenance, the Agency will assume the responsibility and liability for injury
to persons or property resulting from the utilization of the facility or appurtenance so placed into

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, 10 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 10 percent of
the first half of total Contract amount, whichever is greater.
