Which Act requires that the prevailing wage rate and benefits for all federal government construction projects be consistent with federally established mandated rates?

The Davis-Bacon Act is the correct answer because it specifically mandates that contractors and subcontractors engaged in federal construction projects pay their workers the prevailing wage rates and benefits that are determined by the U.S. Department of Labor. This act was enacted to ensure that wages paid on federal construction projects are commensurate with local wage standards, thereby preventing under-bidding by contractors who might otherwise pay below-market wages.

In contrast, the Occupational Safety and Health Act focuses primarily on workplace safety and health standards, ensuring that working conditions are safe and healthy for all employees. The Fair Labor Standards Act addresses wage and hour laws, including the minimum wage and overtime pay, but does not specifically regulate prevailing wage rates for federal construction projects. The Wage and Hour Law, while related to labor regulations more broadly, does not specifically pertain to the requirements set forth in the Davis-Bacon Act regarding federal construction wages. Thus, the focus of the Davis-Bacon Act makes it the most applicable and correct choice in this context.
