The Illinois Prevailing Wage Act (820 ILCS 130) requires contractors and subcontractors to pay laborers, workers and mechanics employed on public works construction projects no less than the general prevailing wage rates for work performed in the same county. The rates, which are determined by the Illinois Department of Labor, are published for each specific construction trade in all 102 counties in the state. The rates consist of hourly cash wages plus fringe benefits to the employee. The prevailing wage law sets uniform pay rates for workers employed on public works construction projects, making contractors’ labor costs predictable and identical as they develop their bids. This ensures that contractors compete on the basis of project management skill, safety and efficiency rather than driving down worker pay.
