Engineer's Estimate of Costs: $ 2,249,400

(F) Final Pay Quantities - See Section 9-1.02C, “Final Pay Item Quantities,” of the

Standard Specifications.

(Note: Gaps in section numbering, above, indicate the Section is blank or does not apply.)

The foregoing quantities are approximate only, being given as a basis for the comparison of bids, and the County of San Mateo does not, expressly or by implication, agree that the actual amount of work will correspond herewith, but reserves the right to increase or decrease the amount of any class or portion of the work, or to omit any portion of the work, as may be deemed necessary or expedient by the Engineer.

Payment to the Contractor for materials furnished and work completed shall be made by the County in accordance with Section 9 of the "Special Provisions" portion of these Contract Documents. Pursuant to Section 22300 of the Public Contract Code, Contractor may, upon his request and at Contractor's expense, substitute equivalent securities for any moneys retained from such payment for the fulfillment of the Contract.

Pursuant to Section 1773 of the California Labor Code, prevailing wage rates in the County have been established by the California Department of

Industrial Relations, and copies are available in the office of the Director of Public

Works. Said prevailing wage rates shall be made available to any interested party on request, and the successful Bidder shall post a copy of the wage rates at the job site. The Contractor’s attention is directed to Section 7-1.02K(2), “Wages,” of the Standard Specifications and the Federal Requirements section of these

Special Provisions. More specifically, reference is made to section FR-2, “Federal

Wage Rates (North County)”.

Additionally:

a. When applicable, both Contractor and Subcontractor hereby agree to pay not less than prevailing rates of wages and be responsible for compliance with all the provisions of the California Labor Code, Article 2-

Wages, Chapter 1, Part 7, Division 2, Section 1770 et seq and Section 1810 et seq. A copy of the prevailing wage scale established by the Department of Industrial Relations is on file in the office of the Director of Public Works, and available at www.dir.ca.gov/DLSR or by phone at 415-703-4774.

California Labor Code Section 1776(a) requires each contractor and subcontractor keep accurate payroll records of trades workers on all public works projects and to submit copies of certified payroll records upon request.

b. Pursuant to State Senate Bill SB 854 (Stat. 2014, chapter 28), effective January 1, 2015:

i. No contractor or subcontractor may be listed on a bid proposal for a public works project unless registered with the Department of

Industrial Relations pursuant to Labor Code section 1725.5 [with limited exceptions from this requirement for bid purposes only under

Labor Code section 1771.1(a)].

ii. No contractor or subcontractor may be awarded a contract for public work on a public works project unless registered with the

Department of Industrial Relations pursuant to Labor Code section

1725.5.

iii. This project is subject to compliance monitoring and enforcement by the Department of Industrial Relations.

Attention is directed to the Federal minimum wage rate requirements in the

Contract documents for this Project. If there is a difference between the minimum wage rates predetermined by the Secretary of Labor and the general prevailing wage rates determined by the Director of the California Department of Industrial Relations for similar classifications of labor, the Contractor and subcontractors shall pay not less than the higher wage rate. The Department will not accept lower State wage rates not specifically included in the Federal minimum wage determinations. This includes

"helper" (or other classifications based on hours of experience) or any other classification not appearing in the Federal wage determinations. Where Federal wage determinations do not contain the State wage rate determination otherwise available for use by the Contractor and subcontractors, the Contractor and subcontractors shall pay not less than the Federal minimum wage rate, which most closely approximates the duties of the employees in question.

Anyone with knowledge of possible bid rigging, bidder collusion, or other fraudulent activities should use the hotline provided below to report these activities.

Reference is made to Section 2-1.50, Bid Rigging,” of the Standard Specifications, which states: “The U.S. Department of Transportation (DOT) provides a toll-free hotline service to report bid rigging activities. Use the hotline to report bid rigging, bidder collusion, or other fraudulent activities. The hotline number is (800)-424-9071. The service is available 24 hours 7 days a week and is confidential and anonymous. The hotline is part of the DOT’s effort to identify and investigate highway construction contract fraud and abuse and is operated under the direction of the DOT Inspector

General.”

Wage rates for overtime shall be paid at not less than one and one-half (1-1/2) times the above rates. Wage rates for Sundays and holidays shall be paid at not less than two (2) times the above rates.

The holidays upon which such rates shall be paid shall be all holidays recognized in the collective bargaining agreement applicable to the particular craft, classification, or type of worker employed on the Project.

It is the policy of the County that Contractors on public projects employ their workers and craftsmen from the local labor market whenever possible. "Local Labor

Market" is defined as the labor market within the geographical confines of the County of

San Mateo, State of California. Consistent with this policy, the Contractor is requested to employ craftsmen and other workers from the local labor market whenever possible to do so.

Each bidder shall submit with the bid, Certificates of Compliance and Intent on a form provided in the "Proposal" section of these Contract Documents, a certificate that bidder is in compliance with the provisions of Title VII of the Civil Rights Act of 1964, the

California Fair Employment and Housing Act and any other federal, State and local laws and regulations relating to equal employment opportunity. With the execution of said certificates, bidder also agrees that bidder will maintain or develop and implement, during the course of the work concerned, a program of hiring and employment, conducted without regard to race, religion, color, national origin, ancestry, sexual orientation, or sex of the applicants. With this certification, bidder shall submit any and all information that may be required by the County in connection with the particular project.

Each bidder is hereby notified of Section 9204 and Section 20104 et seq. of the

Public Contract Code as those Sections (attached hereto as Appendix E) relate to resolution of construction claims, and to Section 3186 of the Civil Code, as amended

January 1, 1999 with regard to stop notices and public entity’s rights to retain monies in order to provide for that entity’s reasonable cost of litigation. The bidder is further notified that all provisions of Section 9204 and Section 20104 et seq. of the Public

Contract Code and Section 3186 of the Civil Code, as outlined above shall be considered as incorporated into and become an integral part of these specifications.

C licenses that are applicable for the majority of the work at the time this contract is awarded. No Contract will be awarded to a Bidder who is not licensed as required by laws of the State of California.
