SB 854 Notice: County public works projects are subject to compliance monitoring and enforcement by the Department of Industrial Relations (DIR) in accordance with Labor Code Section 1771.4(a)(1). As part of this program, Contractors and Subcontractors on Public Works Projects are required to be registered with DIR in accordance with Labor Code Section 1725.5. Unregistered contractors are not qualified to bid on, be listed in a bid proposal, listed as a Subcontractor, or engage in the performance of any Public Works Contract, all as more particularly described in Labor Code Section 1771.1(a). The prime Contractor shall be required to post the job site with all notices required by regulations per Labor Code Section 1771.4(a)(2), whether or not the County also posts.

Labor Code Compliance: Contractor shall comply with the provisions of the Labor Code requiring the payment of prevailing wages on public works, commencing with Section 1720. In accordance with Labor Code, Section 1775, the Contractor shall forfeit an amount, as determined by the Labor Commissioner, for each worker paid less than the applicable prevailing wage rate for the work or craft in which that worker is employed for any work done under Contract by Contractor or by any Subcontractor. Contractor agrees to pay the difference between the prevailing wage rate and amount paid to each worker in accordance with Labor Code, Section 1775 (a)(2)(E).

Pursuant to Labor Code, Section 1770, the Director of the Department of Industrial Relations has ascertained the general prevailing rate of per diem wages and a general prevailing rate for legal holiday and overtime work for each craft required for execution of the Contract.

In accordance with Labor Code, Section 1773.2, copies of the prevailing rate of per diem wages are on file and can be viewed during normal business hours at the County Department of Purchasing and Contracting, located at 5560 Overland Avenue, Suite 270, San Diego, CA 92123-1294.

Wage rates set forth are the minimum that may be paid by the Contractor. Nothing herein shall be construed as preventing the Contractor from paying more than the minimum rates set. No extra compensation whatsoever will be allowed by the County due to the inability of the Contractor to hire labor at minimum rates, nor for necessity for payment by the Contractor of subsistence, travel time, overtime, or other added compensations, all of which possibilities are elements to be considered and ascertained to the Contractor’s own satisfaction in preparing its Proposal.

If it becomes necessary to employ crafts other than those listed in the General Prevailing Wage Rate, the Contractor shall obtain a wage rate determination. The rates thus determined shall be applicable as minimum from the time of initial employment. The Contractor shall be responsible for paying the applicable rate.

The Contractor and each Subcontractor shall keep and make available accurate payroll record in accordance with Labor Code, Section 1771.4(a)(3) and Section 1776. The record shall contain the names, addresses, social security numbers, work classifications, straight time and overtime hours worked each day and week, and the actual per diem wages paid to each journeyman, apprentice, worker, or other employee employed by the Contractor and/or Subcontractor in connection with the Work. Payroll records shall be certified and shall be on forms provided by the Division of Labor Standards Enforcement, or shall contain the same information as those forms. A copy of all payrolls shall be submitted weekly to the Engineer in accordance with Section 7-1.01A(3) “Payroll Records” of the Standard Specifications. The Contractor’s and Subcontractor's certified payroll records shall be available for inspection at the principal office of the Contractor, or at the job site should the principal office be located outside of San Diego County.
