Prevailing Wage The District's obligations under M.C.L. 480.1101, et seq. include ensuring the following:

● Contractor shall determine the prevailing rates of wages and fringe benefits for all classes of construction mechanics called for in the contract.

● A schedule of these rates shall be made part of the contract for work to be performed and shall be printed on the bidding forms.

● Every contractor and subcontractor must fulfill its obligations under the statute relating to prevailing wage.

● The contract must contain the statutory language providing that construction mechanics are intended beneficiaries of the contractual prevailing wage, fringe benefit, and non-discrimination, non-retaliation requirements, and provide that any construction mechanic aggrieved by the failure of a contractor or subcontractor to pay prevailing wages or benefits as specified in the contract or retaliation associated therewith, may bring an action in a court of competent jurisdiction against the contractor or subcontractor for damages or injunctive relief along with other remedies prescribed by statute.

● The Contractor shall provide the District certified payroll records and other records required by law.

Contracts on State Projects which contain provisions regarding payment of prevailing wages as determined by the United States Secretary of Labor or which contain minimum wage schedules which are the same as prevailing wages in the Locality as determined by collective bargaining agreements or understandings between bona fide organizations of Construction Mechanics and their employers are exempt from the above requirements.
