Illinois enforces a demanding prevailing wage regime on public works, and civil construction in the state carries Illinois Prevailing Wage Act rates and electronic certified payroll. A contractor that prices standard labor on Illinois civil work loses margin.
What Illinois prevailing wage requires
The Illinois Prevailing Wage Act requires contractors on public works, including roadway, bridge, and utility construction, to pay locally set prevailing wages and fringe benefits by classification and to file certified payroll with the Illinois Department of Labor through its electronic system. Rates are set by county and updated regularly, and federal aid civil work adds Davis Bacon in parallel. The wage obligation applies across Illinois civil work.
Why the wage burden is easy to miss
The applicable rates and the certified payroll filing requirement sit in the solicitation and Illinois law, not the title, and federal aid projects layer Davis Bacon on top. A contractor that carries standard labor rates, or misses the electronic certified payroll obligation, finds the margin gone after award.
