The Davis-Bacon Act requires contractors on federal construction projects to pay workers prevailing wage rates determined by the Department of Labor. Understanding Davis-Bacon requirements is essential for any contractor pursuing federal work—non-compliance can result in contract termination, debarment, and significant financial penalties.

Why Davis-Bacon Matters

The law ensures federal construction spending supports local wage standards rather than depressing market rates through low-bid competition.

What is the Davis-Bacon Act?

The Davis-Bacon Act (1931) requires contractors and subcontractors on federally-funded construction projects exceeding $2,000 to pay workers the locally prevailing wage rates for their craft.

Key Requirements
  • Wage Rates: Pay at least prevailing rate per classification
  • Fringe Benefits: Pay required fringe (or cash equivalent)
  • Certified Payroll: Submit weekly certified reports
  • Posting: Display wage determination at site
  • Apprentices: Only registered at approved ratios
When It Applies
  • • Federal building construction
  • • Military facilities
  • • Veterans Administration projects
  • • Federal highway (FHWA) projects
  • • Federal transit (FTA) projects
  • • HUD and EPA funded projects

Threshold: Contracts exceeding $2,000

When Davis-Bacon Does NOT Apply
  • • Contracts under $2,000
  • • Supply contracts without construction
  • • Most state/local work without federal funding
  • • Private projects without federal involvement
  • • Maintenance work (some circumstances)
  • • Emergency repairs (limited exceptions)

Frequently Asked Questions

How do I find the prevailing wage rate for my project?

The applicable wage determination is included in contract/bid documents. You can also search SAM.gov for wage determinations by location and project type. Always use the determination specified in the contract.

Can I pay workers above prevailing wage?

Yes. Prevailing wage is a minimum requirement. Paying above prevailing rates is always compliant. Many contractors pay above prevailing to attract quality workers.

How does overtime work with prevailing wage?

Overtime (hours over 40/week) must be paid at 1.5x the basic hourly rate plus the full fringe benefit amount (straight time). Example: If basic rate is $40 and fringe is $15, overtime is $60 + $15 = $75/hour.

What if my subcontractor violates Davis-Bacon?

Prime contractors are responsible for subcontractor compliance. Include compliance requirements in subcontracts, collect and review certified payrolls, and address violations immediately. You may be liable for subcontractor violations.

How long must I keep Davis-Bacon records?

Maintain all payroll records, including certified payrolls, time cards, and pay documentation, for 3 years after project completion.

Conclusion

Davis-Bacon compliance is essential for contractors pursuing federal construction opportunities. Understanding wage determinations, certified payroll requirements, and classification rules helps you bid accurately and execute projects without compliance risk.

While Davis-Bacon adds administrative requirements, federal projects offer stable funding, reliable payment, and consistent opportunity pipelines for qualified contractors.
