existence of any and all addenda.

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

to waive any informality in bids, and to accept, modify, or reject any items of the bid,

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 into is subject to the provisions of the City of San Mateo Charter, which may

supersede certain provisions of the Public Contract Code and other provision of state

law.

13. A contractor or subcontractor shall not be qualified to bid on, be listed in a bid proposal,

subject 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 20183.5

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/

Per Labor Code Section 20103.5, a contractor can register at any time prior to bid

award 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 1725.15. This project is subject to compliance

monitoring and enforcement by the Department of Industrial Relations.

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.

14. 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.

15. 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 City's interest may dictate. The City Council

may exercise its right to modify the award or to reject any or all bids. Any protests to

award of contract shall follow the procedures outlined in City Council Resolution

No. 61, dated June 7, 2004.

16. 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, Bidder may substitute securities

for said five percent (5%) retention or request that City make payments of retentions

earned directly to an escrow agent at Bidder’s expense. The provisions of the Public

Contracts Code Section 22300 are hereby expressly made a part of the contract.

17. The lowest responsible bidder shall submit all required insurance, bonds and signed

agreements within ten (10) days after bid opening.
