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

Payment to the Contractor for materials furnished and work completed shall be
8

NC. E5103
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)].
9

NC. E5103
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
