Informal Bidders List "UPCCAA"

San Joaquin County has adopted the Uniform Public Construction Cost Accounting Act (UPCCAA) and invites all interested California licensed contractors to submit their company for inclusion on the County's Informal Bidding Contractors List for each respective calendar year.

Per California Public Contract Code 22032, any Public Works Project that is estimated to be below $200,000 is subject to the Informal Bidding Procedures set forth by the State of California Uniform Construction Cost Accounting Commission. All trade categories are subject to Informal Bidding Procedures. Contractors that are interested in being on the Informal Bidding Contractors List are required to have a current license and are subject to verification through the Contractors State License Board.

Department of Labor Relations - Prevailing Wage Rates:

In accordance with the provisions of Labor Code Sections 1770 through 1781, the general prevailing rate of wages, as determined by the Director of the Department of Industrial Relations (DIR), shall be paid to all trades performing work under an awarded Contract. The work is subject to compliance monitoring and enforcement by the Department of Industrial Relations.

No contractor or subcontractor may be awarded a contract, on a public works project, on or after April 1, 2015, unless registered with the Department of Industrial relations pursuant to Labor Code section 1725.5. Additionally on or after January 1, 2016, contractor and subcontractor shall be required to furnish electronic certified payroll record to the Labor Commissioner for all public works projects, new or ongoing.

Additional information about these requirements, SB 854, and the new public works program regarding compliance monitoring, administration, and enforcement of prevailing wage law is available on the DIR's website at: Department of Industrial Relations - Director's General Prevailing Wage Determinations and Department of Industrial Relations - Public Works
