 As part of the US Department of Labor ’ s ( DOL ) governmentwide implementation of the Davis @-@ Bacon Act , federal regulations require that all laborers and mechanics who work for a contractor or subcontractor on federally financed construction contracts over $ 2 @,@ 000 must be paid wages not less than those the DOL established for the project location ( i.e. , the prevailing wage ) . This Compliance Requirement was created to assure that recipients oblige contractors to comply with the Davis @-@ Bacon Act , by including in their construction contracts with a contractor or subcontractor a clause or requirement to comply with the Davis @-@ Bacon Act and the DOL regulations . The clause should also include a requirement for the contractor or subcontractor to submit to the recipient weekly ( e.g. , for each week in which any contract work is performed ) a copy of the construction payroll accompanied by statement of compliance . This report is commonly referred to as “ certified payrolls ” , and is often done using Optional Form WH @-@ 347 ( OMB No. 1215 @-@ 0149 ) , a standard form pre @-@ designed by the OMB .
