What is Davis-Bacon?
The Davis-Bacon Act of 1931 is a federal law requiring contractors and subcontractors on federally-funded construction projects to pay workers no less than the locally prevailing wages and fringe benefits for corresponding work on similar projects in the area.
The Act's purpose is twofold: protecting local wage standards from being undercut by contractors importing lower-wage labor, and ensuring federal construction dollars support fair compensation for workers.
Key Davis-Bacon Provisions
Prevailing Wages: Contractors must pay workers at least the wage rates listed in the applicable wage determination for their job classification.
Fringe Benefits: In addition to wages, contractors must provide fringe benefits (health insurance, retirement, vacation) at specified rates—or pay the cash equivalent.
Certified Payroll: Contractors must submit weekly certified payroll reports documenting wages paid, work classifications, and hours worked.
Posting Requirements: Wage determinations must be posted at the job site where workers can see them.
Recordkeeping: Contractors must maintain payroll records for three years after project completion.
When Does Davis-Bacon Apply?
Davis-Bacon applies to federal construction contracts and federally-assisted construction exceeding $2,000. This includes:
Direct Federal Projects
- Construction, alteration, or repair of federal buildings
- Military base construction
- Federal courthouse construction
- National park facilities
- Federal highway construction
Federally-Assisted Projects
Over 60 federal laws extend Davis-Bacon requirements to projects receiving federal assistance:
- Highway Projects: Federal-Aid Highway Act requires Davis-Bacon on federally-funded highway construction
- Housing Projects: HUD-funded affordable housing and community development
- Airport Projects: FAA-funded airport construction and modernization
- Water/Wastewater: EPA-funded water infrastructure projects

- Highway and bridge repair
- Public transit modernization
- Water infrastructure
- Broadband deployment
- Electric vehicle charging infrastructure
- Clean energy projects
Understanding Wage Determinations
Wage determinations specify minimum hourly wage rates and fringe benefit requirements for specific job classifications in specific geographic areas.
How to Find Wage Determinations
The Department of Labor maintains wage determinations at SAM.gov (formerly WDOL.gov). To find the applicable wage determination:
- Navigate to SAM.gov → Wage Determinations
- Search by state and county
- Select construction type (Building, Heavy, Highway, Residential)
- Review classifications and rates
Construction Types
Building Construction: Commercial buildings, schools, hospitals, offices
Heavy Construction: Utilities, water/sewer systems, dams, large structures
Highway Construction: Roads, bridges, tunnels, airport runways
Residential Construction: Housing projects of four stories or less
Reading Wage Determinations
Each wage determination lists:
| Column | Description | |--------|-------------| | Classification | Job title (Carpenter, Electrician, Laborer) | | Basic Hourly Rate | Minimum cash wage required | | Fringe Benefits | Required fringe benefit value | | Total | Combined minimum compensation |
Example:
- Electrician: $42.50/hour basic rate + $18.75 fringe = $61.25 total
- Laborer: $28.00/hour basic rate + $12.50 fringe = $40.50 total
Fringe Benefit Options
Contractors can satisfy fringe benefit requirements through:
- Bona fide benefits: Health insurance, retirement plans, vacation pay
- Cash equivalent: Pay fringe amount as additional wages
- Combination: Mix of benefits and cash
Most contractors find paying cash equivalents simpler for compliance purposes.
Certified Payroll Requirements
Weekly Certified Payroll (WH-347)
Contractors must submit weekly certified payroll reports using Form WH-347 or equivalent. Reports must include:
- Contractor/subcontractor name and address
- Project name and location
- Week ending date
- Employee name, address, last four digits of SSN
- Work classification
- Hours worked each day
- Total hours
- Rate of pay (basic + fringe)
- Gross wages
- Deductions
- Net wages
Certification Statement
Each payroll must include a signed Statement of Compliance certifying:
- Classifications are accurate
- Wages paid meet or exceed prevailing rates
- No unauthorized deductions were made
- Apprentices are properly registered
Knowingly submitting false certifications is a federal crime under 18 U.S.C. § 1001.
Submission Requirements
- Submit payrolls weekly, typically within 7 days
- Prime contractors must collect and submit subcontractor payrolls
- Many agencies accept electronic submissions through systems like LCPtracker
Recordkeeping
Maintain certified payroll records for three years after project completion. Records must include:
- Time cards/daily reports
- Payroll journals
- Cancelled checks or payment records
- Fringe benefit documentation
- Apprenticeship certifications
Common Compliance Mistakes
Misclassification of Workers
Using incorrect job classifications is the most common Davis-Bacon violation. Examples:
Wrong: Paying a worker performing carpenter duties at laborer rates Right: Pay workers based on actual work performed, not job titles
Workers performing duties of multiple classifications during a workweek must be paid the highest applicable rate for all hours, unless accurate time records show hours in each classification.
Apprentice Violations
Apprentices must be:
- Registered with DOL-approved programs
- Working under a journeyworker (ratios vary by trade)
- Paid the percentage of journeyworker rate specified in their agreement
Unregistered apprentices must be paid full journeyworker rates.
Inadequate Recordkeeping
Keep complete records supporting every payroll submission:
- Daily sign-in sheets
- Foreman daily reports documenting work activities
- Employee acknowledgment of wages received
- Fringe benefit plan documentation
Late Payroll Submissions
Submit payrolls weekly without exception. Late submissions trigger agency inquiries and can indicate broader compliance problems.
Failing to Post Wage Determinations
Post the applicable wage determination and WH-1321 poster (Employee Rights under Davis-Bacon) at the job site where workers can see them.
Best Practices for Compliance
Before Bidding
- Review wage determination: Ensure you're pricing the correct determination
- Verify classifications: Confirm all needed trades are covered
- Calculate fully loaded rates: Include fringes in your labor estimates
- Check for modifications: Wage determinations are updated periodically
During Construction
- Train supervisors: Ensure field staff understand classification requirements
- Document daily: Accurate daily reports prevent end-of-project disputes
- Review timely: Catch errors before payroll submission
- Communicate with subs: Ensure subcontractor compliance
Audit Preparation
- Organize records: Maintain files by pay period and employee
- Reconcile regularly: Match payroll records to daily reports
- Self-audit: Conduct periodic internal compliance reviews
- Respond promptly: Address agency inquiries immediately

Frequently Asked Questions
What is the Davis-Bacon Act in simple terms?
The Davis-Bacon Act is a federal law requiring contractors on government construction projects over $2,000 to pay workers at least the local prevailing wage rates. It ensures federal construction dollars support fair wages rather than driving down local pay standards.
Contractors must pay both a basic hourly wage and fringe benefits (or cash equivalent) as specified in wage determinations issued by the Department of Labor for each job classification and geographic area.
How do I find prevailing wage rates for my project?
Find prevailing wage rates at SAM.gov (Wage Determinations section). Search by state, county, and construction type (building, heavy, highway, or residential). The applicable wage determination should also be included in your contract documents.
If the determination changes after contract award, the original determination typically remains in effect for the contract duration. However, verify with the contracting agency, as some modifications may apply.
What happens if I violate Davis-Bacon requirements?
Davis-Bacon violations can result in:
- Wage restitution: Back pay for affected workers, potentially including liquidated damages
- Contract termination: The government may terminate the contract
- Debarment: Contractors can be barred from federal contracts for up to three years
- Criminal penalties: Willful violations and false certifications can result in criminal prosecution
Even unintentional violations require wage restitution. Maintain robust compliance programs to prevent problems before they occur.
Do Davis-Bacon wages include overtime?
Yes, Davis-Bacon wages must be paid for overtime hours, but there's no federal requirement for overtime premium. However, the Contract Work Hours and Safety Standards Act requires time-and-a-half for hours over 40 per week on federal contracts.
Calculate overtime using the basic rate (not including fringe benefits) multiplied by 1.5, then add the full fringe benefit rate. For example:
- Basic rate: $40/hour
- Overtime base: $40 × 1.5 = $60/hour
- Plus fringe: $60 + $15 = $75/hour total overtime rate
What is certified payroll?
Certified payroll is a weekly report (typically Form WH-347) documenting wages paid to each worker on a Davis-Bacon covered project. The report includes employee names, classifications, hours worked, wages paid, and deductions.
Each report includes a signed Statement of Compliance certifying accuracy. Prime contractors must collect and submit certified payrolls from all subcontractors working on the project.
Are all federal projects covered by Davis-Bacon?
Most federal construction projects over $2,000 are covered, but some exemptions exist:
- Service contracts: Covered by Service Contract Act instead
- Maintenance contracts: May not be covered depending on scope
- Supply contracts: Davis-Bacon covers construction only
Additionally, over 60 federal assistance programs extend Davis-Bacon to state and local projects receiving federal funds. Verify coverage in your specific contract documents.
How do fringe benefits work under Davis-Bacon?
Contractors must provide fringe benefits (or cash equivalent) at rates specified in the wage determination. Options include:
- Bona fide benefit plans: Health insurance, retirement contributions, vacation pay meeting DOL requirements
- Cash payment: Pay the fringe amount as additional taxable wages
- Combination: Mix of benefits and cash totaling the required amount
Many contractors pay cash equivalents because it's simpler to document and audit. If using benefit plans, ensure they qualify as bona fide under DOL regulations.
What records must I keep for Davis-Bacon?
Maintain the following records for three years after project completion:
- Certified payroll reports (WH-347 or equivalent)
- Time cards and daily attendance records
- Daily reports documenting work activities
- Cancelled checks or direct deposit records
- Fringe benefit plan documentation
- Apprenticeship registration certificates
- Employee acknowledgment of wages
Organize records by pay period for easy retrieval during audits.
