Prevailing Wage Act

Requires contractor and subcontractor to pay laborers, workers and mechanics employed on public works projects, no less than the general prevailing rate of wages (consisting of hourly cash wages plus fringe benefits) for work of similar character in the locality where the work is performed. Violators must pay workers the difference between the wage paid and the prevailing wage, and are subject to penalties and punitive damages. A contractor or subcontractor found to have violated the Act on two occasions in a five year period may be barred from public works projects for four years.
Contractors are required to post prevailing wage rates at job sites.
