Relations. These wages are set forth in the General Prevailing Wage Rates for this project, available at the Glenn
County Public Works Agency and available from the California Department of Industrial Relations' Internet web
site at http://www.dir.ca.gov.
The Federal minimum wage rates for this project as predetermined by the United States Secretary of Labor are

necessary, will be issued to holders of the contract documents. Future effective general prevailing wage rates
which have been predetermined and are on file with the California Department of Industrial Relations are

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 County 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.

Works/PublicWorks.html for more information. No contract will be entered into without proof of the contractor's
and subcontractors' current registration with the Department of Industrial Relations to perform public work. If
awarded a contract, the bidder and its subcontractors, of any tier, shall maintain active registration with the
Department of Industrial Relations for the duration of the project.
This project is subject to compliance monitoring and enforcement by the Department of Industrial Relations. Each

(5) days of the award.

Code, Section 313 and the regulations adopted pursuant thereto.
PAYMENT RETENTION: Upon the Contractor's request, the County will make payment of funds withheld from
