Illinois enforces one of the more demanding state prevailing wage regimes in the country, and public building work in the state carries Illinois Prevailing Wage Act rates and certified payroll. A general contractor that prices standard labor on an Illinois public job loses the margin it expected.
What the Illinois Prevailing Wage Act requires
The Illinois Prevailing Wage Act requires contractors on public works 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. The rates are set by county and updated regularly. State agency work posts through Illinois systems while local governments post separately, and the wage obligation applies across public building work.
Why Illinois prevailing wage gets priced wrong
The applicable wage rates and the certified payroll filing requirement sit in the solicitation and Illinois law, not the title. A contractor reading scope can carry standard labor rates and miss the Illinois prevailing wage burden and the electronic certified payroll obligation, then find the margin gone after award.
