8+ Free Davis-Bacon Fringe Benefit Calculator Worksheet Templates

A structured document facilitates the computation of supplemental compensation amounts for employees working on federally funded construction projects. These projects are governed by prevailing wage laws. The document typically includes sections for listing employee names, hours worked, and the specific benefits provided, such as health insurance, retirement plans, and vacation pay. Each benefit’s hourly equivalent value is calculated and aggregated to determine the total hourly fringe benefit contribution for each employee. For example, if an employee works 40 hours in a week and receives $200 in health insurance benefits, the hourly equivalent is $5.00, which is then added to other benefit values.

The utilization of such a document ensures compliance with regulations mandating that contractors provide a combination of wages and benefits that meet or exceed the predetermined prevailing wage rate for a specific job classification. It provides a clear, auditable record of benefit contributions, mitigating the risk of wage violations and potential penalties. Historically, enforcing prevailing wage requirements has sought to protect local labor standards and ensure fair compensation for construction workers on public projects, thereby preventing a race to the bottom in wages and benefits.
