A prevailing wage affidavit is a form often requested by the owner of a project from the prime contractor or subcontractors. This form states that all labor, through a particular time period (typically the pay period), has been paid in full by the prime contractor and/or his subcontractors, at the hourly rate mandated by the wage authority. The wage authority is often the state or federal government. The wage rates are constantly changing and increasing.  This form is typically only required on publicly funded projects. The Davis Bacon Act is an example of a federal law passed requiring that all workers on a project that’s being state/federally funded must be paid at least the minimum based on their trade, the bare labor rate, and the labor burden rates. This form is typically requested with progress pay applications for the work covering the pay period being applied for and owners will hold payments until all forms are received.
