At the option of the City, either the insurer shall reduce or eliminate such deductibles or self-insurance retention as respects the City, its officers, officials, employees and volunteers, or the Contractor shall provide a financial guarantee satisfactory to the City guaranteeing payment of losses and related investigations, claim administration and defense expenses.

d. Other Insurance Provisions – The general liability and automobile liability

policies are to contain, or be endorsed to contain, the following provisions:

1) The City, its officers, officials, employees, and volunteers are to be covered as insureds on the CGL and automobile liability policies with respect to liability arising out of work or operations performed by or on behalf of the Contractor including materials, parts, or equipment furnished in connection with such work or operations and automobiles owned, leased, hired, or borrowed by or on behalf of the Contractor. General liability coverage can be provided in the form of an endorsement to the Contractor’s insurance (at least as broad as ISO Form CG 20 10, 11 85 or both CG 20 10 and CG 23 37 forms if later revisions are used).

2) For any claims related to this project, the Contractor’s insurance

coverage shall be primary insurance as respects the City, its officers, officials, employees, and volunteers. Any insurance or self-insurance maintained by the City, its officers, officials, employees or volunteers shall be excess of the Contractor’s insurance and shall not contribute with it.


3) Each insurance policy required by this clause shall provide that coverage shall not be canceled, except after 30 days prior written notice has been provided to the City or 10 days prior written notice for non-payment of premium.

e. Acceptability of Insurer – Insurance is to be placed with insurers with a current A.M. Best rating of no less than A:VII unless otherwise acceptable to the City. Exception may be made for the State Compensation Insurance Fund when not specifically rated.

f. Verification of Coverage – Contractor shall furnish the City with original certificates and amendatory endorsements, or copies of the applicable insurance language, effecting coverage required by this contract. All certificates and endorsements are to be received and approved by the City before work commences. However, failure to obtain the required documents prior to the work beginning shall not waive the Contractor’s obligation to provide them. The Entity reserves the right to require complete, certified copies of all required insurance policies, including endorsements, required by these specifications, at any time.

g. Subcontractors – Contractor shall require and verify that all subcontractors

maintain insurance meeting all the requirements stated herein.

h. Waiver of Subrogation – Contractor hereby agrees to waive rights of subrogation which any insurer of Contractor may acquire from Contractor by virtue of the payment of any loss. Contractor agrees to obtain any endorsement that may be necessary to affect this waiver of subrogation.

The Workers’ Compensation policy shall be endorsed with a waiver of subrogation

in favor of the City for all work performed by the Contractor, its employees, agents and subcontractors.

If the Contractor fails to maintain any insurance as required by this section, the City

of Yuba City may take out such insurance to cover any damages for which the City of Yuba City might be held liable on account of the operations under this contract, and deduct and retain the amount of the premiums for such insurance from any sums due the Contractor under the contract. Nothing herein contained shall be construed as limiting in any way the extent to which the Contractor may be held responsible for payment of damages resulting from his operations, or those of any subcontractor under him. Maintenance of proper insurance coverage is a material element of the contract and failure to maintain or renew coverage or to provide evidence of renewal may be treated by the City as a material breach of contract.

4.6 No Personal Liability – Neither the Mayor, the Council, the Engineer, nor any other officer or authorized assistant or agent shall be personally responsible for any liability arising under the contract.

4.7 Responsibility of City – The City shall not be held responsible for the care or

protection of any materials or parts of the work prior to final acceptance, except as expressly provided in these Special Provisions.


4.8 Domestic Materials – Only such materials shall be used in the performance of this

contract as conform to the requirements of Chapter 4 of Division 5 of Title 1 of Government Code of the State of California except as otherwise provided in certain treaties and general trade agreements of the United States.

4.9 Apprenticeship Requirements – Attention is directed to the provisions in Sections 1777.5, 1777.6 and 1777.7 of the Labor Code concerning the employment of apprentices by the Contractor or any subcontractor under him.

Section 1777.5, as amended in 1989, requires the Contractor or subcontractor employing tradesmen in any apprenticeable occupation to apply to the joint apprenticeship committee nearest the site of the public works project and which administers the apprenticeship program in that trade for a certificate of approval. The certificate will fix the ratio of apprentices to journeymen that will be used in the performance of the contract to be not less than one to five hours except:

a. When employment in the area of coverage by the joint apprenticeship committee has exceed an average of fifteen percent (15%) in the ninety (90) days prior to the request for certificate; or

b. When the number of apprentices in training in the area exceeds a ratio of

one to five (1:5); or c. When the trade can show that it is replacing at least 1/30 of its membership

through apprenticeship training on an annual basis statewide or locally; or d. When the contractor provides evidence that he employs registered

apprentices on all of his contracts on an annual average of not less than one apprentice to eight journeymen; or

e. When a joint apprenticeship committee submits an application to DAS for

an alternative ratio based on a 1:5 daily worker count if the hourly ratio is not feasible for that particular craft or trade.

In addition to the above exceptions, contracts of specialty contractors not bidding

through a general contractor and involving less than twenty (20) working days or Thirty Thousand Dollars ($30,000) are exempt from the provisions of Section 1777.5. This is the same exemption that applies to contracts of general contractors. However, a subcontractor bidding through a general contractor must comply with Section 1777.5 no matter how small the subcontract if the contract between the general contractor and the awarding body is covered by Section 1777.5.

Effective January 1, 1990, the Contractor must promptly provide certain contract award information to the joint apprenticeship committee of the apprenticeable craft or trade in the area of the site of the public work. This contract award information must include an estimate of the journeymen hours required, the number of apprentices to be employed, and the approximate date of apprentice employment.


The Contractor is required to make contributions to local funds established for the

administration of apprenticeship programs or to the California Apprenticeship Council if he employs registered apprentices or journeymen in any apprenticeable trade on such contracts and if other Contractors on the public works site are making such contributions.

Noncompliance by the Contractor and subcontractor under him with the requirements of Sections 1777.5 and 1777.6 shall result in denial of right to bid on contracts and civil penalties as more particularly set forth in Section 1777.7.

Information relative to apprenticeship standards, wage schedules and other

requirements may be obtained from the Director of Industrial Relations, ex-officio the Administrator of Apprenticeship, San Francisco, California, or from the Division of Apprenticeship Standards and its branch offices.

4.10 Subcontracting – Attention is directed to the provisions in Section 8-1.01, “Subcontracting” of the Standard Specifications. The “Subletting and Subcontracting Fair Practices Act” (Public Contract Code Section 4100 through and including 4114, inclusive) shall apply to the work the subject of this invitation. Said Act requires subcontractors, if used for such work, to be listed and identified in the prime contractor’s proposal. It further prohibits the substitution of subcontractors, except as therein specifically authorized (Section 4107 and 4107.5); said Act provides that if the prime contractor fails to specify a subcontractor or specifies more than one subcontractor for the same portion of the work to be performed, in excess of one-half of one percent of the prime contractor’s total bid, under those circumstances, it shall be presumed that the prime contractor agrees that he is fully qualified to perform the work himself and that he shall perform the work himself. Each bidder shall, with respect to the work the subject of this invitation, list in his proposal:

a. The name and location of the place of business of each subcontractor who will perform work or labor or render services 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 one percent of the prime contractor’s total bid.

b. The portion of the work which will be done by each such subcontractor.

One subcontractor shall be listed for each such portion. Pursuant to the provisions in Section 1777.1 of the Labor Code, the Labor

Commissioner publishes and distributes a list of contractor ineligible to perform work as a subcontractor on a public works project. This list of debarred contractors is available from the Department of Industrial Relations web site at

http://www.dir.ca.gov/dlse/debar.html

4.11 Differing Site Conditions


a. During the progress of the work, the Contractor shall immediately, and before the following conditions are disturbed, notify the Engineer, in writing, of any:

1) Material that 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;

2) Subsurface or latent physical conditions at the site differing from

those indicated; 3) Unknown physical conditions at the site differing from and

generally recognized as inherent in work of the character provided for in the contract.

b. Upon written notification, the Engineer will promptly investigate the

conditions, and if the Engineer finds that the conditions do materially differ or do involve hazardous waste and cause a decrease or increase in the Contractor’s cost of or time required for performance of any part of the work, an adjustment, excluding loss of anticipated profits, will be made and the contract modified in writing accordingly.

In the event that a dispute arises whether the conditions materially differ, or

involve hazardous waste, or cause a decrease or increase in the Contractor’s cost of or time required for performance of any part of the work, the Contractor shall not be excused from any scheduled completion date provided for by the contract, but shall proceed with all work to be performed under the contract. The Contractor shall retain any and all rights provided either by contract or by law which pertain to the resolution of disputes and protests between the contracting parties.

4.12 Working Hour Restrictions – Eight (8) hours of labor is a legal day’s work. Any

worker’s time of service is restricted to eight (8) hours during any calendar day and forty (40) hours during a calendar week, unless overtime compensation is paid at not less than one and one-half times the basic rate of pay. The Contractor shall pay a penalty of Twenty-five Dollars ($25) for each day a worker is employed in violation of these provisions.

4.13 Examination and Audit – Notwithstanding any other provision of law, every contract involving the expenditure of public funds in excess of Ten Thousand Dollars ($10,000) entered into by any State agency, board, commission, or department, or by any other public entity, including a City, County, or District, shall be subject to the examination and audit of the State Auditor, at the request of the public entity or as part of any audit of the public entity, for a period of three (3) years after final payment under the contract. Contractor shall also be subject to examination and audit for the same time period.

4.14 Equal Opportunity Clause – During the performance of this contract, the contractor agrees as follows:


a. The contractor will not discriminate against any employee or applicant for employment because of race, color, religion, sex, or national origin. The contractor will take affirmative action to ensure that applicants are employed, and that employees are treated during employment without regard to their race, color, religion, sex, or national origin. Such action shall include, but not be limited to, the following: employment, upgrading, demotion or transfer; recruitment or recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and selection for training, including apprenticeship. The contractor agrees to post in conspicuous places, available to employees and applicants for employment, notices to be provided setting forth the provisions of this nondiscrimination clause.

b. The contractor will, in all solicitations or advertisements for employees placed by or on behalf of the contractor, state that all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, or national origin.

c. The contractor will send to each labor union or representative of workers with which the contractor has a collective bargaining agreement or other contract or understanding, a notice to be provided advising the said labor union or workers' representatives of the contractor's commitments under this section, and shall post copies of the notice in conspicuous places available to employees and applicants for employment.

d. The contractor will comply with all provisions of Executive Order 11246 of September 24, 1965, and of the rules, regulations, and relevant orders of the Secretary of Labor.

e. The contractor will furnish all information and reports required by Executive Order 11246 of September 24, 1965, and by rules, regulations, and orders of the Secretary of Labor, or pursuant thereto, and will permit access to its books, records, and accounts by the administering agency and the Secretary of Labor for purposes of investigation to ascertain compliance with such rules, regulations, and orders.

f. In the event of the contractor's noncompliance with the discrimination clauses of this contract or with any of the said rules, regulations, or orders, this contract may be canceled, terminated, or suspended in whole or in part and the contractor may be declared ineligible for further government contracts or Federally assisted construction contracts in accordance with procedures authorized in Executive Order 11246 of September 24, 1965, and such other sanctions may be imposed and remedies invoked as provided in Executive Order 11246 of September 24, 1965, or by rules, regulations, or orders of the Secretary of Labor, or as otherwise provided by law.

g. The contractor will include the portion of the sentence immediately preceding paragraph (1) and the provisions of paragraphs (1) through (7) in every subcontract or purchase order unless exempted by rules, regulations, or orders of the Secretary of Labor issued pursuant to Section 504 of Executive Order 11246 of September 24, 1965, so that such provisions will be binding upon each subcontractor or vendor. The contractor will take such action with respect to any subcontract or purchase order as the


administering agency may direct as a means of enforcing such provisions, including sanctions for noncompliance; provided, however, that in the event a contractor becomes involved in, or is threatened with, litigation with a subcontractor or vendor as a result of such direction by the administering agency, the contractor may request the United States to enter into such litigation to protect the interests of the United States.

SECTION 5 WATER AND DUST CONTROL

5.1 Water – The Contractor is responsible for finding his own water source. No water connection is available onsite. Obtaining the water source shall be the Contractors responsibility. Water is available from Linda County Water District and it is the contractor’s responsibility to negotiate cost and use of metered water from hydrants with Linda County Water District. 5.2 Dust Control – Dust control measures shall be taken in conformance to Section 14-9.03 of the Standard Specifications. Contractor shall water the construction site at sufficient intervals to preclude the nuisance of dust caused by the Contractor’s operations and/or wind and traffic, at no additional compensation.

SECTION 6 PROGRESS OF THE WORK, LIQUIDATED

DAMAGES, AND CONTRACT TIME

6.1 Prosecution of Work – The City will issue a Notice to Proceed to the Contractor after the contracts have been fully executed. The Contractor shall diligently prosecute the work to completion before the expiration of the number of working days provided herein. 6.2 Liquidated Damages – Should the Contractor fail to complete all work under the contract within the time provided therefor, he shall pay to the City the sum of Eight Thousand Dollars ($8,000) for each calendar day delay in finishing the work beyond such contract period, all in accordance with Section 8-1.10 of the Standard Specifications. The City may deduct such payment from the amounts due the Contractor under the contract. 6.3 Time for Completion – All work under this contract shall be completed within a maximum of forty-five (45) working days from the date stated in the Notice to Proceed as the date to start work. No work shall be allowed after October 31, 2020 at the project site.

6.4 Extension of Contract Time

a. If the Contractor finds it impossible, for reasons beyond his control, to complete the work within the contract time as specified or as extended in accordance with the provisions of this subsection, he may, at any time prior to the expiration of the contract


time, as extended, make a written request to the Engineer for an extension of time, setting forth therein the complete facts which he believes will justify the granting of such request.

The Contractor’s pleas that insufficient time was originally specified shall

not constitute a valid reason for extension of contract time. If the Engineer determines that the prosecution of the work was delayed or hampered by conditions beyond the control and without the fault of the Contractor, he may extend the time for completion in such amount as conditions may justify. Such extended time for completion shall then be in full force and effect the same as though it were the original time for completion.

Suspension of work by the Engineer, or extension of the contract time, shall

not constitute grounds for any claims by the Contractor for damages or extra compensation, but the period of such suspensions or extensions shall be taken into consideration in determining the time for completion, as herein provided. When final acceptance has been duly made by the Engineer, as prescribed in Section 3.4, the daily time charge will cease.

b. Any dispute hereunder shall be considered pursuant to the Standard Specifications, and the Contractor shall give immediate notice to the Engineer, along with all pertinent facts relative to such dispute.

6.5 Right-of-Way Delays – The City has scheduled relocation of public utilities to provide for little or no delay to the contractor. It is anticipated that utility companies may be engaged in relocation work immediately prior to Contractor’s work on the project. Some coordination of scheduling between the Contractor and the utility company may be necessary to minimize or eliminate delays to the Contractor. If the Contractor is unavoidably delayed because of the City’s failure to clear right-of-way, no contract time will be charged during such delay period. No direct compensation will be made for such delay. 6.6 Force Account Payment – The added markup of Labor, Materials, and Equipment Rental as listed in Sections 9-1.04B, “Labor,” 9-1.04C, “Materials,” and 9-1.04D, “Equipment Rental,” are amended as follows: To the total of the direct costs there will be added a markup of 15 percent to the cost of labor, 12 percent to the cost of materials and 12 percent to the equipment rental.

6.7 Pre-construction Conference – Prior to the issuance of the Notice to Proceed, a pre-construction conference will be held at the office of the Director of Public Works for the purpose of discussing with the Contractor the scope of work, contract drawings, specifications, existing conditions, materials to be ordered, equipment to be used, and all essential matters pertaining to the prosecution and the satisfactory completion of the project as required. The Contractor shall provide the following items at the pre-construction conference:

Schedule Material Submittals Door Hangers / Public Notice


The Contractor’s representatives at this conference shall include all major

superintendents for the work and may include major subcontractors.

SECTION 7 PAYMENT

7.1 General – Payment will be made on the basis of the unit prices bid for the various

items of work and the quantities of such items completed, and measured in accordance with these Special Provisions.

The prices bid for the various items of work, as listed on the bid schedule, shall be full compensation for furnishing all labor, tools, equipment, materials, and services required by the Plans, these Special Provisions, and the Standard Specifications, to provide a complete work serviceable in all respects. Unless otherwise noted on the plans or specified in these Special Provisions, no additional compensation will be made for incidental work identified in the Plans, these Special Provisions, or the Standard Specifications. Compensation for such incidental work shall be considered included in the price or prices bid, for various related items of work, in the bid schedule.

7.2 Progress Payments – The City will make monthly progress payments to the Contractor for the work under the contract. Such progress payments are not intended to imply acceptance of the work completed or to be accurate as to the quantities of work indicated, but to provide the Contractor with operating capital reasonably consistent with the amount of work completed and materials supplied.

The amounts of such progress payments will be based on the Engineer’s Estimate of the quantities or portions of the work completed at the time of preparation of such estimate.

Upon Contractor’s submittal of documentation of the amounts paid for acceptable materials furnished at the site, but not yet installed, the cost of such materials will be compensated in the progress payments, to a maximum of fifty percent (50%) of the associated bid price.

A retention of five percent (5%) of the total value of the work completed to date will be made from the amount due on each progress payment for partial security for fulfillment of the contract. At the Contractor’s request and at his expense, he may offer to substitute securities within the meaning of Section 22300 of the Public Contract Code in an amount equivalent to the amount withheld, to wit, bank or savings and loan certificates of deposit. This option is available to the Contractor as provided by Section 22300 of the Public Contract Code and must be initiated by him by request and at his sole cost and expense, and upon such request, City shall permit the substitution of securities equivalent to the amount withheld to ensure satisfactory completion and fulfillment of the contract. Contractor shall remain the beneficial owner of any securities substituted for monies withheld and shall receive any interest thereon during the period of retention. Such securities shall be released to Contractor upon satisfactory completion of the contract, to wit, thirty-five (35) days from and after the Notice of Completion.


The securities deposited by Contractor as substitution for funds withheld shall be deposited with City pursuant to the provisions of Section 22300 of the Public Contract Code and shall be ultimately released at the conclusion and satisfactory completion of the contract as herein provided for.

7.3 Final Payment – The Engineer will, after completion of the work, make a final estimate of the amount of work done thereunder, and the value of such work, and the City will pay the entire sum so found to be due after deducting therefrom all previous payments and all amounts to be kept and all amounts to be retained under the provisions of the contract. All prior partial estimates and payments shall be subject to correction in the final pay estimate and payment. The final payment will not be due and payable until the expiration of thirty-five (35) days from the date of recordation of the notice of acceptance of completion in the Office of the County Recorder of Sutter County.

It is mutually agreed between the parties to the contract that no payments made under the contract shall be conclusive evidence of the performance of the contract, either wholly or in part, against any claim of the City, and no payment shall be construed to be acceptance of any defective work or improper material.

7.4 Resolution of Claims – This section is intended to comply with Article 1.5 (commencing with Section 20104) of Chapter 1 of Part 3 of Division 2 of the Public Contract Code and shall apply to all claims by the Contractor against the City in any amount arising out of or relating to the contract.

Claims filed by the Contractor shall be in writing and shall be in sufficient detail to enable the Engineer to ascertain the basis and amount of said claims. Claims must be filed on or before the date of Final Payment. Nothing herein is intended to extend the time limit or supersede notice requirements otherwise provided by the Contract for the filing of claims. Claims submitted by the Contractor shall be accompanied by a notarized certificate containing the following language:

For claims over Fifty Thousand Dollars ($50,000), the Engineer shall respond in writing to all written claims within sixty (60) days of receipt of the claim, or may request, in writing, within thirty (30) days of receipt of the claim, any additional documentation supporting the claim or relating to defenses to the claim the City may have. The Engineer’s written response to the claim, as further documented, shall be submitted to the Contractor within thirty (30) days after receipt of the further documentation, or within a period of time no greater than that taken by the Contractor in producing the additional information or requested documentation, whichever is greater. If the Contractor disputes the Engineer’s written response, or if the Engineer fails to respond within the time prescribed, the Contractor may notify the Engineer, in writing, either within fifteen (15) days of receipt of Engineer’s response or within fifteen (15) days of the Engineer’s failure to respond within the time prescribed, respectively, and demand in writing an informal conference to meet and confer for settlement of the issues in dispute. Upon such written demand, City shall schedule a meet and confer conference within thirty (30) days for settlement of the dispute.

If following the meet and confer conference, the claim or any portion remains in dispute, the Contractor may file a claim pursuant to Chapter 1 (commencing with Section 900) and Chapter 2 (commencing with Section 910) of Part 3 of Divisions 3.6 of Title 1 of the Government Code. For purposes of those provisions, the running of the period of time within which a claim must be filed shall be tolled from the time the Contractor initially submits the written claim pursuant the section until the time the claim is denied, including any period of time utilized by the meet and confer conference.

As provided by Public Contract Code Section 20104.4, the following procedures are established for all civil actions filed to resolve claims subject to this section:

a. Within sixty (60) days, but no earlier than thirty (30) days, following the filing or responsive pleadings, the court shall submit the matter to nonbinding mediation unless waived by mutual stipulation of both parties. The mediation process shall provide for the election within fifteen (15) days by both parties of a disinterested third person as


mediator, shall be commenced within thirty (30) days of the submittal, and shall be concluded within fifteen (15) days from the commencement of the mediation unless a time requirement is extended upon a good cause showing to the Court.
