In all cases where the commission has established a prevailing rate of wages, the contract executed between any state agency and the successful bidder or highway contractors shall contain a provision requiring the successful bidder and all of the successful bidder's subcontractors to pay the rate of wages so established. The successful bidder or highway contractors and all subcontractors shall strictly comply with these provisions of the contract.
