9. The time of completion for this contract shall be seventy-five (75) working days, beginning from

11. The right is reserved, as the interest of the City may require, to reject any or all bids, to waive any

informality in bids, or in the case of a single bid being received to extend the acceptance date by

up to thirty (30) days with notice. The City of San Mateo is a charter City and any contract entered

to the requirements of Section 4104 of the Public Contract Code, or engage in the performance of

any contract for public work, as defined in this chapter, unless currently registered and qualified

to perform public work pursuant to Section 1725.5. It is not a violation of this section for an

unregistered contractor to submit a bid that is authorized by Section 7029.1 of the Business and

Professions Code or by Section 10164 or 20103.5 of the Public Contract Code, provided the

contractor is registered to perform public work pursuant to Section 1725.5 at the time the contract

is awarded. This project is subject to compliance monitoring and enforcement by the Department

of Industrial Relations.

No contractor or subcontractor may be listed on a bid proposal for a public works project and

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. This project is subject to compliance monitoring and enforcement by the

Department of Industrial Relations. As an additional requirement, Assembly Bill 219 adds

Section 1720.9 to the Labor Code. This bill expands the definition of public works under the

California Prevailing Wage Law and is a requirement for this project. For reference, please

see:

https://www.dir.ca.gov/ConcreteDeliveryPrevailingWage/AB_219_Fact_Sheet.html

In general, the prevailing wage scale, as determined by the Director of Industrial Relations of the

State of California, in force on the day this bid was announced or determined by the administrator

of the Wage and Hour Division, U.S. Department of Labor, in force on the day bids are opened,

whichever is higher, will be the minimum paid to all craftsmen and laborers working on this

project. In some cases, prevailing wage determinations have either a single asterisk (*) or double

asterisks (**) after the expiration date in effect on the date of advertisement for bids.

In cases where the prevailing wage determinations have a single asterisk (*) after the expiration

date which are in effect on the date of advertisement for bids, such determinations remain in

effect for the life of the project. Prevailing wage determinations which have double asterisks (**)

after the expiration date indicate that the basic hourly wage rate, overtime, and holiday pay rates,

and employer payments to be paid for work performed after this date have been predetermined.

If work is extended past this date, the new rate must be paid and should be incorporated in

contracts the Contractor enters into.

Pursuant to Section 1773 of the Labor Code, the general prevailing wage rates in the county, or

counties, in which the work is to be done have been determined by the Director of the California

Department of Industrial Relations. The wages as set forth in the General Prevailing Wage Rates

for this project will be posted at the job site. It is understood that it is the responsibility of the

bidder to determine the correct scale. The City will keep a copy of the wage scale in the City

Clerk’s office for the convenience of bidders. The State Prevailing Wage Rates may also be

obtained from the California Department of Industrial Relations internet website at

http://www.dir.ca.gov. Any errors or defects in the materials in the City Clerk’s office will not

excuse a bidder’s failure to comply with actual scale then in force.

13. The U.S. Department of Transportation (DOT) provides a toll-free “hotline” service to report bid

rigging activities. Bid rigging activities can be reported Mondays through Fridays between 8:00

AM and 5:00 PM, Eastern Time, telephone number 1-800-424-9071. Anyone with knowledge of

possible bid rigging, bidder collusion, or other fraudulent activities should use the “hotline” to

report these activities. The “hotline” is part of DOT’s continuing efforts to identify and

investigate the highway construction contract fraud and abuse and is operated under the direction

of the DOT Inspector General. All information will be treated confidentially and caller

anonymity will be respected.

Said City Representative shall report the results of the bidding to the City Council at a later date,

at which time the City Council may award the contract to the lowest responsible bidder as so

reported; or as the City's interest may dictate, City Council may exercise its right to modify the

award or to reject any or all bids.

14. The lowest responsible bidder shall submit all required insurance and signed agreements within

five (5) business days after bid opening.

15. To ensure performance, City reserves the right to retain five percent (5%) of the contract price for

35 days after it records the Notice of Completion. However, pursuant to the Public Contracts

Code Section 22300, Contractor may substitute securities for said five percent (5%) retention or

request the City make payments of retentions earned directly to an escrow agent at Contractor’s

expense. The provisions of the Public Contracts Code Section 22300 are hereby expressly made a

part of the contract.

16. The work performed as part of this contract is subject to the restrictions and requirements of any

and all federal, state and San Mateo County Health Orders (collectively “Health Orders”) in

effect during the contract period, which may be changed by such government agencies without

notice. Bidders shall refer to the latest San Mateo County Health Order, and any of its established

construction safety protocols for construction projects.
