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. 
The County of San Joaquin, hereby notifies all Bidders that it will affirmatively ensure that in any contract entered into pursuant to  this advertisement, minority business enterprises will be afforded full opportunity to submit bids in response to this invitation and will  not be discriminated against on the grounds of race, color, sex or national origin in consideration for an award. 
This project is subject to compliance monitoring and enforcement by the Department of Industrial Relations. Pursuant to Section 1773 of the Labor Code, the general prevailing wage rates in the County in which the work is to be done  
have been determined by the Director of the California Department of Industrial Relations. These wages are set forth in the General  Prevailing Wage Rates for this project are available from the California Department of Industrial Relations' Internet web site at Director's  General Prevailing Wage Determinations (ca.gov). The Federal minimum wage rates for this project as predetermined by the United  States Secretary of Labor are available from the Department of Labor's internet web site at https://sam.gov/. Addenda to modify the  Federal minimum wage rates, if necessary, will be issued to holders of "Bid and Contract" books. Future effective general prevailing  wage rates, which have been predetermined and are on file with the California Department of Industrial Relations are referenced but  not printed in the general prevailing wage rates.   
Attention is directed to the Federal minimum wage requirements in Section 7-1.02K(2),”Wages,” of this book. 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  will 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 will pay not  less than the Federal minimum wage rate which most closely approximates the duties of the employees in question.
