Public Works

Public works refers to construction, alteration, demolition, installation, or repair work (including maintenance) done under contract and paid by public funds. Public works projects do not include those done by a public agency with its own employees.

With minor exceptions, all workers employed on public works projects must be paid the prevailing wage determined by the Director of the Department of Industrial Relations according to the type of work and location. The prevailing wage rates are usually based on rates specified in collective bargaining agreements.

The application also provides agencies that administer public works programs with a searchable database of qualified contractors.
