The Davis-Bacon Act requires companies working on federal government construction projects to pay their laborers and mechanics at least the prevailing wages and benefits as determined by the Department of Labor. Compliance with this law mandates the use of certified payroll, a system for contractors to submit weekly wage reports to demonstrate they are fulfilling the wage requirements set forth for each project. This act applies to all contractors and subcontractors working on federally funded or assisted contracts in excess of $2,000 for the construction, alteration, or repair of public buildings or public works.
