2018 Prevailing Wage Rates

The rate schedules linked to on this page contain the prevailing wage rates required to be paid for work performed on or after August 15, 2018 on public works projects in each County. Pursuant to 820 ILCS 130/4, public bodies in each County that have active public works projects are responsible for notifying all contractors and subcontractors working on those public works projects of the change (if any) to rates that were previously in effect. The failure of a public body to provide such notice does not relieve contractors or subcontractors of their obligations under the Prevailing Wage Act, including the duty to pay the relevant prevailing wage in effect at the time work subject to the Act is performed.
