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 perfor-mance 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 Cali-fornia 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 Subcon-tractor-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.
Revised 6/12/18 Contract No. 6071 Page 26 of 212
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. Contractor is prohibited from performing any work on this project with a subcontractor who is
ineligible to perform work on a public works project pursuant to Labor Code Sections 1771.1 or 1777.7.

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 as-
signed 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), which-
ever 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.
Revised 6/15/17 Contract No. 6071 Page 58 of 212
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 Con-
tractor 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 proceed-ings 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 deter-mination 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 subcon-tracted.
2-3.3 Status of Subcontractors. Subcontractors shall be considered employees of the Con-tractor, 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 Con-
tract 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 Proce-dure 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 6/15/17 Contract No. 6071 Page 59 of 212
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 commis-sioner. 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. 2-5 PLANS AND SPECIFICATIONS. 2-5.1 General.

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 inter-ests 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 Con-
tractor 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 in-volved, 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 con-formance 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 cov-ered 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 per-cent 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 6/15/17 Contract No. 6071 Page 70 of 212
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 Specifica-tions, 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 Con-
tract 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 Contrac-tor. 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 spec-ified 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 notifi-
cation 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 6/15/17 Contract No. 6071 Page 71 of 212
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 com-pensation 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 equip-ment 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 Sec-tion 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” pub-lished 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 inci-dentals. 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 Con-tractor 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 rec-ommended by the manufacturer.
Revised 6/15/17 Contract No. 6071 Page 72 of 212
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 Con-tractor 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 Sub-
contractor, 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 subcon-
tracted 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 doc-uments 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.
2. Describe and list quantities of materials used.
Revised 6/15/17 Contract No. 6071 Page 73 of 212
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 fol-lowing 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 per-
formed; 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 perfor-mance 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 hap-pening 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 par-ticular 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 6/15/17 Contract No. 6071 Page 74 of 212
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 under-
stands 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 re-
quest 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.
Revised 6/15/17 Contract No. 6071 Page 75 of 212
The authority within the dispute resolution chain of command is limited to recommending a reso-lution to a claim to the City Manager. Actual approval of the claim is subject to the change order
provisions in the contract. All claims by the -Contractor shall be resolved in accordance with Public Contract Code section
9204, which is set forth below: 9204. (a) The Legislature finds and declares that it is in the best interests of the state and its

(B) The claimant shall furnish reasonable documentation to support the claim. (C) If the public entity needs approval from its governing body to provide the claimant a written statement identifying the disputed portion and the undisputed portion of the claim, and the gov-
erning body does not meet within the 45 days or within the mutually agreed to extension of time following receipt of a claim sent by registered mail or certified mail, return receipt requested, the public entity shall have up to three days following the next duly publicly noticed meeting of the governing body after the 45-day period, or extension, expires to provide the claimant a written statement identifying the disputed portion and the undisputed portion.

shall select a mediator and those mediators shall select a qualified neutral third party to mediate with regard to the disputed portion of the claim. Each party shall bear the fees and costs charged by its respective mediator in connection with the selection of the neutral mediator. If mediation is unsuccessful, the parts of the claim remaining in dispute shall be subject to applicable procedures outside this section.

Any mediation utilized shall conform to the timeframes in this section. (D) Unless otherwise agreed to by the public entity and the contractor in writing, the mediation conducted pursuant to this section shall excuse any further obligation under Section 20104.4 to mediate after litigation has been commenced. (E) This section does not preclude a public entity from requiring arbitration of disputes under pri-vate arbitration or the Public Works Contract Arbitration Program, if mediation under this section
does not resolve the parties’ dispute. (3) Failure by the public entity to respond to a claim from a contractor within the time periods described in this subdivision or to otherwise meet the time requirements of this section shall result
in the claim being deemed rejected in its entirety. A claim that is denied by reason of the public entity’s failure to have responded to a claim, or its failure to otherwise meet the time requirements
Revised 6/15/17 Contract No. 6071 Page 77 of 212
of this section, shall not constitute an adverse finding with regard to the merits of the claim or the responsibility or qualifications of the claimant.
(4) Amounts not paid in a timely manner as required by this section shall bear interest at 7 percent per annum. (5) If a subcontractor or a lower tier subcontractor lacks legal standing to assert a claim against a
public entity because privity of contract does not exist, the contractor may present to the public entity a claim on behalf of a subcontractor or lower tier subcontractor. A subcontractor may re-quest in writing, either on his or her own behalf or on behalf of a lower tier subcontractor, that the
contractor present a claim for work which was performed by the subcontractor or by a lower tier subcontractor on behalf of the subcontractor. The subcontractor requesting that the claim be pre-sented to the public entity shall furnish reasonable documentation to support the claim. Within 45 days of receipt of this written request, the contractor shall notify the subcontractor in writing as to whether the contractor presented the claim to the public entity and, if the original contractor did not present the claim, provide the subcontractor with a statement of the reasons for not having
done so. (e) The text of this section or a summary of it shall be set forth in the plans or specifications for any public works project that may give rise to a claim under this section. (f) A waiver of the rights granted by this section is void and contrary to public policy, provided, however, that (1) upon receipt of a claim, the parties may mutually agree to waive, in writing, mediation and proceed directly to the commencement of a civil action or binding arbitration, as applicable; and (2) a public entity may prescribe reasonable change order, claim, and dispute resolution procedures and requirements in addition to the provisions of this section, so long as the contractual provisions do not conflict with or otherwise impair the timeframes and procedures
set forth in this section. (g) This section applies to contracts entered into on or after January 1, 2017.

tractual obligations.

SECTION 4 – CONTROL OF MATERIALS 4-1 MATERIALS AND WORKMANSHIP. 4-1.1. General. All materials, parts, and equipment furnished by the Contractor in the Work shall be new, high grade, and free from defects. Quality of work shall be in accordance with the gener-ally 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 con-
sidered 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 di-rected by the Engineer.
If the Contractor fails to replace any defective or damaged work or material after reasonable no-tice, 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 Spec-
ifications. 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 Con-tractor 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 neces-sary 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 fabrica-tion, 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 accepta-ble 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 in-spection 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 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
Revised 6/15/17 Contract No. 6071 Page 81 of 212
regulations as may apply. Contractor shall furnish Engineer with such information as may be nec-essary 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 pur-chase 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 (ap-
proved 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 ex-pense, 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 require-ments 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 im-proper 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.
Revised 6/15/17 Contract No. 6071 Page 82 of 212
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 nec-essary by noncompliance with the specifications shall be borne by the Contractor.
4-1.5 Certification. The Engineer may waive materials testing requirements of the Specifica-tions 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 durabil-ity, 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, ap-pearance, 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 propor-
tioning 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.
Revised 6/15/17 Contract No. 6071 Page 83 of 212
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 Regula-
tions 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 oper-ating 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 pres-
sure 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. Cal-ibration 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 Mod-ified 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 de-fined 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 inves-
tigation 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 in-formation 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 co-operative 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 acknowl-edgement, 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 re-quest 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
Revised 6/15/17 Contract No. 6071 Page 84 of 212
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 inves-tigation 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 pertain-ing 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 Engi-neer 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.
Revised 6/15/17 Contract No. 6071 Page 85 of 212
SECTION 5 – UTILITIES 5-1 LOCATION. The Agency and affected utility companies have, by a search of known rec-ords, 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 utili-ties indicated on the Plans is not guaranteed. Where underground main distribution conduits such as water, gas, sewer, electric power, tele-phone, 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 (Under-ground 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 sup-port 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 6/15/17 Contract No. 6071 Page 86 of 212
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 pro-tection 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 proce-
dures required to maintain or restore the integrity of the system. 5-3 REMOVAL. Unless otherwise specified, the Contractor shall remove all interfering por-
tions 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. Add the following: 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 Con-tractor 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 compensation will be allowed therefor 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 avail-able 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 Sec-tion 5-1.
The Contractor may be given an extension of time for unforeseen delays attributable to unrea-sonably 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 iden-tified 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 altera-tions 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
Revised 6/15/17 Contract No. 6071 Page 87 of 212
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 6/15/17 Contract No. 6071 Page 88 of 212
SECTION 6 – PROSECUTION, PROGRESS, AND ACCEPTANCE OF THE WORK 6-1 CONSTRUCTION SCHEDULE AND COMMENCEMENT OF WORK. Except as other-
wise provided herein and unless otherwise prohibited by permits from other agencies as may be required by law the Contractor shall begin work within 30 calendar days 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 man-agement 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 precon-struction 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 Base-line 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 re-quired 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 se-
quencing, 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.
Revised 6/15/17 Contract No. 6071 Page 89 of 212
6-1.2.4 Schedule Software. The Contractor shall use commercially available software equal to the Windows 2000 compatible “Suretrak” program by Primavera or “Project” program by Microsoft
Corporation to prepare the Baseline Construction Schedule and all updates thereto. The Contrac-tor shall submit to the Agency a CD-ROM data disk with all network information contained thereon, in a format readable by a Microsoft Windows 2000 system. The Agency will use a “Suretrak”,
“Project” or equal software program for review of the Contractor’s schedule. Should the Contractor elect to use a scheduling program other than the “Suretrak” program by Primavera or “Project” program by Microsoft Corporation the Contractor shall provide the Engineer three copies of the
substituted program that are fully licensed to the Agency and 32 class hours of on-site training by the program publisher for up to eight Agency staff members. The classes shall be presented on Mondays through Thursdays, inclusive, between the hours of 8:00 a.m. and 5:00 p.m. The on-site training shall be held at 1635 Faraday Avenue, Carlsbad, California. The dates and times of the on-site training shall be submitted to the Engineer for approval five working days before the start of the on-site training. The on-site training shall be completed prior to the submittal of the first
Baseline Construction Schedule. 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 activi-ties, 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 ac-curately 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 Con-struction 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 Contrac-tor’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 du-ration 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.
Revised 6/15/17 Contract No. 6071 Page 90 of 212
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 Contrac-
tor 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 Engi-neer. 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 pro-
visions 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 Construc-tion 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 cor-rections 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 dur-ing 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.
Revised 6/15/17 Contract No. 6071 Page 91 of 212
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. 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 resub-mittal 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 re-turning 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 Sec-
tion 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 substan-tially 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
Revised 6/15/17 Contract No. 6071 Page 92 of 212
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 Sched-
ule 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 Revi-sions 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. The work includes removing existing asphalt, base, sidewalk, curb, gutter, driveways, and landscaping behind the sidewalk; installing new as-phalt, base, sidewalk, curb, gutter, driveways; grind and overlay of asphalt, traffic signal, and restriping. 6-2.3 Project Meetings. The Engineer will establish the time and location of regular Project Meetings. The Contractor’s Representative shall attend each Project Meeting.

6-3 SUSPENSION OF WORK.
6-3.1 General. The Work may be suspended in whole or in part when determined by the Engi-neer 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 ar-
chaeological 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.

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.

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 Con-tractor 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.

Agency under law. 6-5 TERMINATION OF CONTRACT. The Board may terminate the Contract at its own dis-
cretion 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 Contrac-tor 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 Con-tractor 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.

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 com-
pleted 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 perma-
nent, 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 com-pleted 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.

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 $500. 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 $500 per day is the minimum value of costs and actual damages caused by the Contractor to complete the Work within the allotted time. Any progress payments made after the specified completion date shall not constitute a waiver of this paragraph or of any damages. 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 im-provement 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.
In the event the Agency exercises its right to place into service and utilize all or part of any com-pleted 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 service, except for any such injury to persons or property caused by any willful or negligent act or omission by the Contractor, Subcontractor, their officers, employees, or agents.

Revised 6/15/17 Contract No. 6071 Page 106 of 212
traffic pattern for the area and is no longer required for the direction of public traffic. When tem-porary pavement delineation is required to be removed, all lines and marks used to establish the
alignment of the temporary pavement delineation shall be removed. 7-10.3.6 Preparation of New, or Modifications and Additions to Existing, Traffic Control Plan Sheets. If no traffic control plans (TCP) or Traffic Control Staging plans (TCP) are included in the project plans, or if the Contractor elects to modify TCP included in the project plans, the Contractor shall have such new or modified TCP prepared and submitted as a part of the Work
for any and all construction activities that are located within the traveled way. The Contractor shall have TCP prepared and submitted as a part of the Work for any construction activities that are a part of this project that are not included in the project plans. The Contractor must submit the TCP for the Engineer’s review in conformance with the requirements of Section 2-5.3, et seq. and obtain the Engineer’s approval of the TCP prior to implementing them. The minimum 20-day re-view period specified in Section 2-5.3.1 for shop drawings and submittals shall pertain to each
submittal of TCP, new, modified or added to, for the Engineer’s review. New or revised TCP sub-mittals shall include all TCP needed for the entire duration of the Work. Each phase of the TCP shall be shown in sufficient scale and detail to show the lane widths, transition lengths, curve radii, stationing of features affecting the traffic control plan and the methodology proposed to transition to the subsequent TCP phase. When the vertical alignment of the traveled surface differs from the finished pavement elevation vertical curves must also be shown. Such modifications, supple-ments and/or new design of TCP shall meet the requirements of the Engineer and the latest California Manual on Uniform Traffic Control Devices as published by CALTRANS. Such modifi-cation, addition, supplement, and/or new design of TCP shall be prepared by a registered professional engineer appropriately registered in the State of California. The Engineer shall be the sole judge of the suitability and quality of any such modifications, supplements, and/or new
designs to TCP. The Engineer may approve any such modifications, supplements, and/or new designs to the TCP when, in the Engineer’s sole opinion, such modifications, supplements, and/or new designs to the TCP prepared by the registered professional engineer retained by the Con-
tractor will be beneficial to the best interests of the Agency. Such modification, addition, supplement, and/or new design shall not be implemented and no work shall be commenced that is contingent on such approval until the changed TCP are approved by the Engineer. The prepa-
ration of such modification, addition, supplement, and/or new designs of TCP shall not presuppose their approval or obligate the Agency in any fashion. Submittal and review require-ments for such modifications, supplements, and/or new designs to TCP shall conform to the requirements of Section 2-5.3 Shop Drawings and Submittals. 7-10.3.7 Payment. The Contractor shall provide traffic control at the contract lump sum price bid.

Revised 6/15/17 Contract No. 6071 Page 111 of 212
SECTION 9 – MEASUREMENT AND PAYMENT 9-1 MEASUREMENT OF QUANTITIES FOR UNIT PRICE WORK. 9-1.1 General. Unless otherwise specified, quantities of work shall be determined from meas-urements or dimensions in horizontal planes. However, linear quantities of pipe, piling, fencing and timber shall be considered as being the true length measured along longitudinal axis. Unless otherwise provided in Specifications, volumetric quantities shall be the product of the
mean area of vertical or horizontal sections and the intervening horizontal or vertical dimension. The planimeter shall be considered an instrument of precision adapted to measurement of all areas.
9-1.2 Methods of Measurement. Materials and items of work which are to be paid for on basis of measurement shall be measured in accordance with methods stipulated in the particular sec-
tions involved. 9-1.3 Certified Weights. When payment is to be made on the basis of weight, the weighing

The Contractor shall furnish the Engineer with dupli-cate licensed weighmaster’s certificates showing actual net weights. The Agency will accept the certificates as evidence of weights delivered. 9-1.4 Units of Measurement. The system of measure for this contract shall be the U.S. Standard Measures. 9-2 LUMP SUM WORK. Items for which quantities are indicated “Lump Sum”, “L.S.”, or “Job”, shall be paid for at the price indicated in the Bid. Such payment shall be full compensation for the items of work and all work appurtenant thereto.
When required by the Specifications or requested by the Engineer, the Contractor shall submit to the Engineer within 15 days after award of Contract, a detailed schedule in triplicate, to be used
only as a basis for determining progress payments on a lump sum contract or designated lump sum bid item. This schedule shall equal the lump sum bid and shall be in such form and sufficiently detailed as to satisfy the Engineer that it correctly represents a reasonable apportionment of the
lump sum. 9-3 PAYMENT 9-3.1 General. The quantities listed in the Bid schedule will not govern final payment. Payment to the Contractor will be made only for actual quantities of Contract items constructed in accord-ance with the Plans and Specifications. Upon completion of construction, if the actual quantities show either an increase or decrease from the quantities given in the Bid schedule, the Contract Unit Prices will prevail subject to the provisions of Section 3-2.2.1. The unit and lump sum prices to be paid shall be full compensation for the items of work and all appurtenant work, including furnishing all materials, labor, equipment, tools, and incidentals. Payment will not be made for materials wasted or disposed of in a manner not called for under
the Contract. This includes rejected material not unloaded from vehicles, material rejected after it
Revised 6/15/17 Contract No. 6071 Page 112 of 212
has been placed, and material placed outside of the Plan lines. 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 precau-tions 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 owner-ship 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 equip-ment 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. Guarantee periods shall not be affected by any payment but shall commence on the date of re-cordation of the “Notice of Completion.”
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 appli-cable laws. At the expiration of 35 days from the date of acceptance of the Work by the Board, or as pre-
scribed 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 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.
Revised 6/15/17 Contract No. 6071 Page 113 of 212
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 Engi-
neer 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 pay-ment 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 re-maining 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 liqui-dated damages under 6-9. As provided in Section 22300 of the California Public Contract Code, the Contractor may substi-
tute 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 corre-
sponding 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 Esti-mate. 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. Should the Contractor fail to submit the statement and supporting documentation within
the time specified, the Contractor acknowledges that full and final payment has been made for all contract bid items and change order items. If the Contractor submits a written statement with documentation in the aforementioned time, the Engineer will review the disputed item within 30 calendar days and make any appropriate adjust-ments on the Final Payment. Remaining disputed quantities or amounts not approved by the
Engineer will be subject to resolution as specified in Section 3-5, Disputed Work. The written statement filed by the Contractor shall be in sufficient detail to enable the Engineer to
ascertain the basis and amount of said disputed items. The Engineer will consider the merits of the Contractor’s claims. It will be the responsibility of the Contractor to furnish within a reasonable time such further information and details as may be required by the Engineer to determine the
Revised 6/15/17 Contract No. 6071 Page 114 of 212
facts or contentions involved in its claims. Failure to submit such information and details will be sufficient cause for denying payment for the disputed items.
9-3.2.1 Payment for Claims. Except for those final payment items disputed in the written state-ment required in Section 9-3.2 all claims of any dollar amount shall be submitted in a written
statement by the Contractor no later than the date of receipt of the final payment estimate. Those final payment items disputed in the written statement required in Section 9-3.2 shall be submitted no later than 30 days after receipt of the Final Payment estimate. No claim will be considered that
was not included in this written statement, nor will any claim be allowed for which written notice or protest is required under any provision of this contract including Sections 3-4 Changed Condi-tions, 3-5 Disputed Work, 6-6.3 Payment for Delays to Contractor, 6-6.4 Written Notice and Report, or 6-7.3 Contract Time Accounting, unless the Contractor has complied with notice or protest requirements.
The claims filed by the Contractor shall be in sufficient detail to enable the Engineer to ascertain the basis and amount of said claims. The Engineer will consider and determine the Contractor’s claims and it will be the responsibility of the Contractor to furnish within a reasonable time such further information and details as may be required by the Engineer to determine the facts or con-tentions involved in its claims. Failure to submit such information and details will be sufficient cause for denying the claims. Payment for claims shall be processed within 30 calendar days of their resolution for those claims approved by the Engineer. The Contractor shall proceed with informal dispute resolution under Section 3-5, Disputed Work, for those claims remaining in dispute. 9-3.3 Delivered Materials. When provided for in the Specifications, and subject to the limitation and conditions therein, the cost of materials and equipment delivered but not incorporated into the Work will be included in the progress estimate.

DAYS = total number of 24 hour periods during which the plates will be utilized at the site being considered.
WEEKEND = total number of Saturdays, Sundays and holidays that the plates will be utilized at the site being considered. NIGHTS = total number of overnight periods that the plates will be in place, exclusive
of Saturday, Sunday and holiday nights. WEATHER = total number of 24-hour periods that the plates will be utilized at the site being considered when the possibility of rain exceeds 40 percent.
SPEED = the design speed in kilometers per hour or miles per hour, as applicable in the formulae above, of the street where the plates are to be installed. This number shall not be reduced for construction zone speed reductions. SLOPE = the quotient of the vertical differential divided by the horizontal distance. The vertical and horizontal dimensions shall be measured at the locations spanning a distance of 15 m (50’) up and downstream of the position of the
proposed steel plate bridging. LANES = the number of lanes where plates will be used. When the computed value of the plate score exceeds 50, steel plate bridging shall not be used unless, and at the sole discretion of the Engineer, the Engineer determines that no alternative method of construction is possible in lieu of using steel plate bridging or that other overriding considerations make the use of steel plate bridging acceptable. Alternatives considered to bridg-ing shall include, but not be limited to, detouring traffic, construction detour routes, tunneling, boring and other methods of trenchless construction. Unless specifically noted in the provisions of the Engineer's approval, the use of steel plate bridging at each location so approved shall not exceed four (4) consecutive working days in any given week.

Project Description
Describe project intent, existing/proposed drainage patterns, net increase in impervious area, and green
street performance strategies.
If the project consists entirely of “routine maintenance” activities as outlined in Table 1-2 of the County BMPDM (i.e. road resurfacing, utility trenching, etc), clearly state so and provide a thorough description of
these activities. Routine maintenance projects are not required to complete the rest of this SWQMP form. The project proposes to remove the existing pedestrian island on the southwest corner of the intersection,
lengthen the dedicated right-turn lane on eastbound El Camino Real to southbound College Boulevard, and
relocate the traffic signal. Impervious areas include the concrete medians, sidewalks, and curb ramps, and
asphalt pavement. Pervious areas include landscaping and bio-swale areas. The curb inlet located after the
right turn onto southbound College Blvd will be replaced in kind. Prior to the curb inlet, the project proposes
bio-swales along the curb and gutter that will collect runoff traveling north on College Blvd.
The existing impervious area is 11,050 sqft (0.25 Ac)
The proposed impervious area is 9,050 sqft (0.21 Ac)
The project proposes a 2,000 sqft (0.05 Ac) net decrease in impervious area at El Camino Real and College
Boulevard. DMA 100 drains to BMP 100, which is a bio-swale area. BMP is located at the southwest corner
of the intersection. The surface types draining into this BMP include concrete hardscape and asphalt paving.
While not all new impervious area within DMA 100 enters BMP 100, the BMP has been sized to treat an
equivalent DCV of DMA 100. This is a common practice for Green Streets projects, which typically are
constrained in terms of available area to locate BMPs. BMPs will utilize retention and infiltration. The
measured infiltration rate of existing onsite soils was found to be 0.8 inches/hour, which reduces to 0.4
inches/hour design infiltration rate. Refer to the BMP calculations in Attachment 1d. BMP 100, which is a bio-
swale, serves as retention area by bioretention. The BMP is located between the curb & gutter and the
proposed sidewalk on the southwest corner of the intersection. The surface type draining into this BMP
includes the proposed asphalt paving and concrete hardscapes (DMA 100). Runoff not retained in the BMP
will travel via curb and gutter and will enter the storm drain system through the relocated curb inlet.

STORM WATER STANDARDS
QUESTIONNAIRE
E-34
INSTRUCTIONS:
To address post-development pollutants that may be generated from development projects, the city requires that new development and significant redevelopment priority projects incorporate Permanent Storm Water Best Management
Practices (BMPs) into the project design per Carlsbad BMP Design Manual (BMP Manual). To view the BMP Manual, refer to the Engineering Standards (Volume 5).
This questionnaire must be completed by the applicant in advance of submitting for a development application (subdivision, discretionary permits and/or construction permits). The results of the questionnaire determine the level of
storm water standards that must be applied to a proposed development or redevelopment project. Depending on the outcome, your project will either be subject to ‘STANDARD PROJECT’ requirements or be subject to ‘PRIORITY DEVELOPMENT PROJECT’ (PDP) requirements. Your responses to the questionnaire represent an initial assessment of the proposed project conditions and impacts. City staff has responsibility for making the final assessment after submission of the development application. If staff
determines that the questionnaire was incorrectly filled out and is subject to more stringent storm water standards than initially assessed by you, this will result in the return of the development application as incomplete. In this case, please
make the changes to the questionnaire and resubmit to the city. If you are unsure about the meaning of a question or need help in determining how to respond to one or more of the
questions, please seek assistance from Land Development Engineering staff.
A completed and signed questionnaire must be submitted with each development project application. Only one completed and signed questionnaire is required when multiple development applications for the same project are
submitted concurrently.

1. INTRODUCTION
This report presents the results of geotechnical investigation SCST, Inc. (SCST) performed for the
El Camino Real and College Boulevard Intersection Improvements project located in the City of
Carlsbad, California. Additionally, a preliminary infiltration feasibility study was performed as part of
our investigation.
1.1 SITE AND PROJECT DESCRIPTION
The project alignment is located on the southwest corner of the El Camino Real and College
Boulevard intersection. The general project location is shown on the site vicinity map
(Figure 1). At the project site, El Camino Real exists as a major six-lane road with a raised
median, dedicated single left- and right-turn lanes, and bike lanes on either side. A raised
pedestrian island separates the eastbound turn lane to College Boulevard from southbound
College Boulevard. The site drainage is gently towards the northwest, away from the
shoulder.
We understand that the proposed improvements will consist of the removal of the existing
pedestrian island, construction of a right-turn-only lane on eastbound El Camino Real to
southbound College Boulevard, relocation of a traffic signal, and construction of a small
retaining wall. The turn lane will encroach into existing shoulder. Additionally, stormwater
BMP facilities will be constructed at the project site.
1.2 SCOPE OF WORK
The purpose of our geotechnical investigation was to assess the existing geotechnical
conditions at the site and provide conclusions and recommendations for the design and
construction of the project. The scope of work performed by SCST consisted of the
following:
• Marking the core locations for DigAlert purposes
• Preparing an encroachment permit application, traffic control plans, and submitting a
no-fee traffic control permit application to the City
• Coring the existing pavement and sampling subgrade at three locations to
approximately six feet below existing pavement surface to allow logging and
sampling of subgrade materials for examination and laboratory testing. Backfilling
test pits and patching core holes with rapid set concrete after obtaining soil samples
• Performing a borehole percolation test to evaluate infiltration characteristics
• Performing laboratory testing of selected soil samples to determine pertinent
classification and engineering properties of the subgrade material

• Preparing this illustrated report presenting the conclusions and recommendations of
the geotechnical investigation
2. FIELD EXPLORATION
Our subsurface exploration was conducted on October 4, 2017 and consisted of coring the existing
pavement at three (3) locations and excavating the subsurface materials to between approximately
2½ to 6 feet below the existing pavement surface. Additionally, we constructed a percolation test
boring to a depth of approximately 5 feet below the existing surface outside of the existing
pavement. An SCST engineer logged and sampled the materials encountered in the borings in
accordance with the Unified Soil Classification System (USCS). Disturbed bulk samples were
obtained from the borings and then transported to our accredited, in-house geotechnical laboratory
for testing. Logs of the borings are presented in Appendix I and the USCS is presented on Figure I-
1. The approximate locations of the borings are presented on the subsurface investigation map
(Figure 2).
The borings were backfilled with dry concrete mix, and the pavements were patched with Caltrans
approved, high strength, rapid set concrete.
3. LABORATORY TESTING
Selected samples obtained from the borings were tested to evaluate pertinent classification and
engineering properties and enable development of geotechnical conclusions. Laboratory testing of
representative soil samples included:
• Atterberg limits (ASTM D)
• Grain size distribution (ASTM D422)
• Resistance (R) value (California Test 301)
• pH & resistivity (Cal 643, ASTM G51)
• Soluble chlorides (Cal 422)
• Soluble sulfate (Cal 417)
Brief descriptions of the laboratory test procedures and the test results are presented in Appendix
III.
4. FINDINGS
4.1 SURFACE AND SUBSURFACE CONDITIONS
Based on exploratory borings, the existing AC thickness is between approximately 8 and 8½
inches. The AC pavement was underlain by between approximately 16 and 24 inches of
Michael Baker International, Inc. October 27, 2017 El Camino Real and College Boulevard Intersection Improvements SCST No. 170364P4-1

aggregate base (AB) material. The subgrade material encountered consisted of moist,
medium dense, well-graded sand, and medium stiff clay. The subsurface materials were
generally consistent along the project alignment.
Table 1 summarizes the details of boring locations, existing structural pavement section
composition, and subgrade soil classification. Groundwater or caving was not encountered
in the borings during our investigation.

4.2 IN SITU INFILTRATION TESTING
Our in situ infiltration testing was performed on October 5, 2017 and consisted of constant
head, borehole percolation testing at a depth of approximately 5 feet below the existing
surface, in general accordance with the San Diego Regional BMP Design Manual and
County of San Diego On Site Sewage Disposal Manual. The testing was performed by an
SCST engineer following a pre-soak period. Table 2 presents the tested infiltration rates.
The results of the percolation testing are presented in Appendix III.
Table 2 Results of In situ Borehole Percolation Testing
5. CONCLUSIONS AND RECOMMENDATIONS
The proposed improvements are considered feasible from a geotechnical standpoint. Although
not encountered, the main geotechnical consideration affecting the planned construction of the
improvements is the potential for overly moist, pumping subgrade conditions. Site preparation
will need to be performed to prepare the subgrade for the proposed improvements.

5.1 SITE PREPARATION
Site preparation should begin with the removal of existing pavements and associated
improvements, landscaping, and debris. The debris and unsuitable material generated
during removals should be exported and disposed of in accordance with applicable
regulations. Underground utilities located within the proposed limits of the construction
should be removed or abandoned, capped off, or relocated so as not to interfere with
earthwork operations. If appropriate, abandoned pipelines can be filled with grout or slurry
as recommended by and observed by the geotechnical engineer.
5.2 SUBGRADE PREPARATION
The subgrade should be evaluated by the geotechnical engineer. Unless otherwise
recommended, the top 12 inches of subgrade should be scarified, moisture conditioned to
near optimum moisture content, and compacted to at least 95 percent relative compaction.
Soft or yielding areas should be removed to expose competent material and replaced with
compacted fill or aggregate base. Stabilization may also be recommended.
5.3 NEW STRUCTURAL PAVEMENT SECTIONS
El Camino Real is striped with three traveled lanes and bike lanes in each direction with a
raised median and a posted speed limit of 55 miles per hour. The average daily traffic (ADT)
volumes exceed 35,000. Peak-hour volumes from eastbound ECR to southbound College
Boulevard are approximately 500 vehicles during the morning commute. These volumes are
estimated to translate to a Traffic Index (TI) of approximately 11.
SCST used the Caltrans Highway Design Manual pavement design procedures and
methods to assist in evaluating appropriate structural pavement sections. Based on the
tested R-value and assumed Traffic Index (TI) values, preliminary flexible asphalt concrete
and rigid Portland cement concrete (PCC) pavement sections for 20-year life cycles are
presented in Table 3.

Aggregate base and asphalt concrete should conform to the Caltrans Standard
Specifications or the “Greenbook” and should be moisture conditioned to near optimum
moisture content and compacted to at least 95 percent relative compaction. Aggregate base
should have an R-value of not less than 78. The materials and methods of construction
should conform to good engineering practices and the local minimum standards.
5.4 RETAINING WALLS
Foundations
Retaining walls can be supported on shallow spread footings. Spread footings should
extend at least 12 inches below lowest adjacent finished grade. Footing bottoms should rest
on competent material. A minimum width of 24 inches is recommended for continuous
footings. An allowable bearing capacity of 2,000 pounds per square foot (psf) can be used.
The allowable bearing capacity can be increased by 500 psf for each foot of depth below
the minimum and 250 psf for each foot of width beyond the minimum up to a maximum of
3,000 psf. The bearing value can be increased by ⅓ when considering short-term loads,
including wind or seismic forces.
Earth Pressures
The at-rest earth pressure for the design of restrained earth retaining structures with level
backfills can be taken as equivalent to the pressure of a fluid weighing 60 pounds per cubic
foot (pcf). The active earth pressure for the design of unrestrained earth retaining structures
with level backfills can be taken as equivalent to the pressure of a fluid weighing 40 pcf. The
above values assume a granular and drained backfill condition. An additional 20 pcf should
be added to these values for walls with a 2:1 (horizontal: vertical) sloping backfill. An
increase in earth pressure equivalent to an additional 2 feet of retained soil can be used to
account for surcharge loads from light traffic.
Lateral loads will be resisted by friction between the bottoms of footings and passive
pressure on the faces of footings and other structural elements below grade. An allowable
coefficient of friction of 0.30 can be used. Passive pressure can be computed using an
allowable lateral pressure of 250 psf per foot of depth below the ground surface for level
ground conditions. Reductions for sloping ground should be made.
The passive pressure can be increased by ⅓ when considering the total of all loads,
including wind or seismic forces. The upper 1 foot of soil should not be relied on for passive
support unless the ground is covered with pavements or slabs.
Michael Baker International, Inc. October 27, 2017 El Camino Real and College Boulevard Intersection Improvements SCST No. 170364P4-1
Carlsbad, California Page 6
Wall Drainage
Retaining walls should be designed to resist hydrostatic pressures or be provided with a
backdrain to reduce the accumulation of hydrostatic pressures. Backdrains may consist of a
2-foot-wide zone of ¾-inch crushed rock. The backdrain should be separated from the
adjacent soils using a non-woven filter fabric, such as Mirafi 140N or equivalent. Weep
holes should be provided, or a perforated pipe (Schedule 40 PVC) should be installed at the
base of the backdrain and sloped to discharge to a suitable storm drain facility. As an
alternative, a geocomposite drainage system such as Miradrain 6000 or equivalent placed
behind the wall and connected to a suitable storm drain facility can be used. The project
architect should provide waterproofing specifications and details. Figure 3 shows typical
conventional retaining wall backdrain details.
5.5 SOIL CORROSIVITY
Representative samples of the onsite soils were tested to evaluate corrosion potential. The
test results are presented in Appendix II. The project design engineer can use the sulfate
results in conjunction with ACI 318 to specify the water/cement ratio, compressive strength
and cementitious material types for concrete exposed to soil. A corrosion engineer should
be contacted to provide specific corrosion control recommendations.
5.6 STORMWATER BMP DESIGN
Evaluation of stormwater infiltration feasibility was performed in general accordance with the
San Diego Regional BMP Design Manual. The tested infiltration rates indicate relatively
favorable conditions for the design and construction of the proposed BMP facilities.
However, due to the clayey nature of the subgrade materials, and the anticipated heavy
demand on the pavements, BMP facilities adjacent to the roadway are anticipated to
contribute to increased maintenance and reduced roadway life.
6. GEOTECHNICAL ENGINEERING DURING CONSTRUCTION
SCST should observe pavement construction and perform appropriate laboratory tests to evaluate
the degree of compaction achieved and material characteristics. In the event unusual or
unanticipated conditions are encountered, the presence of the geotechnical engineer during
construction will enable modification of the pavement section findings or the development of
additional findings on a timely basis.
7. LIMITATIONS
SCST should be advised of changes in the project scope so that the findings can be evaluated with
respect to the revised plans. The findings in this report are valid as of the date of this report.
Michael Baker International, Inc. October 27, 2017 El Camino Real and College Boulevard Intersection Improvements SCST No. 170364P4-1
Carlsbad, California Page 7
Changes in the condition of the runway can, however, occur with the passage of time, whether they
are due to natural processes or work in this or adjacent areas. In addition, changes in the standards
of practice and government regulations can occur. Thus, the findings in this report could be
invalidated wholly or in part by changes beyond our control. This report should not be relied upon
after a period of two years without a review by us verifying the suitability of the findings to site
conditions at that time.
In the performance of our professional services, we comply with that level of care and skill ordinarily
exercised by members of our profession currently practicing under similar conditions and in the
same locality. The client recognizes that subsurface conditions may vary from those encountered at
the exploratory locations and that our data, interpretations, and findings are based solely on the
information obtained by us. We will be responsible for those data, interpretations, and findings, but
will not be responsible for interpretations by others of the information developed. Our services
consist of professional consultation and observation only, and no warranty of any kind whatsoever,
express or implied, is made or intended about the work performed or to be performed by us, or by
our proposal for consulting or other services, or by our furnishing of oral or written reports or
findings.

PREFORMED THERMOPLASTIC PAVEMENT MATERIAL
1. USE: A durable, high skid and slip resistant, pavement marking material suitable for use as bike lane, bike path, bus lane, roadway, intersection, airport, commercial or private pavement delineation and markings. For use on asphalt or portland cement concrete pavement surfaces. 1.1. The material must be a resilient emerald green color preformed thermoplastic product which contains a minimum of thirty percent (30%) intermixed anti-skid/anti-slip elements with a hardness range of 7-9 (Mohs scale), and where the top surface contains anti-skid/anti-slip elements with a hardness of 9 (Mohs scale).
1.2. The material shall be resistant to the detrimental effects of motor fuels, antifreeze, lubricants, hydraulic fluids, etc. 1.3. The material shall be capable of being applied on bituminous and/or portland cement concrete pavements by the use of a handheld heat torch, and/or infrared heater.
1.4. The material shall be capable of being applied to asphalt and portland cement concrete surfaces without preheating the application surface to a specific temperature.
1.5. The material shall be capable of conforming to pavement contours, breaks and faults through the action of traffic at normal pavement temperatures.
1.6. The material is typically supplied in segments measuring 2 ft. x 3 ft. (.61 m x .915 m). 1.7. The material shall be capable of being applied in temperatures down to 45ºF (7.2ºC) without any special storage, preheating or treatment of the material before application. 1.8. The material shall contain heating indicators evenly distributed on the surface that shall act as visual cues during
both the application process and post-application. 1.9. If required, white, retroreflective and skid resistant preformed thermoplastic symbols and/or word legends may be incorporated into the skid/slip resistant material background in an interconnected fashion, such that the two materials shall be factory assembled together and applied as a single layer. 2. MANUFACTURING LOCATION, CONTROL AND ISO CERTIFICATION: The marking material must be
produced in the United States, and the manufacturer must be ISO 9001:2008 certified for design, development and manufacturing of preformed thermoplastic pavement markings, and provide proof of current certification.
3.
