Contractors pursuing federally funded infrastructure work must navigate a complex web of wage and labor standards, chief among them the Davis-Bacon Act (DBA). With the Bipartisan Infrastructure Law (BIL) channeling unprecedented funding into roads, bridges, water systems, and energy projects, the overwhelming majority of these investments fall under DBA protections. Understanding how to comply is essential for any contractor bidding on these projects.

Understanding the Davis-Bacon Act and Its Role Under the BIL
Enacted ninety years ago, the Davis-Bacon Act requires that workers on federally funded or assisted construction contracts receive locally prevailing wages and fringe benefits. The law applies to contracts exceeding $2,000 and is administered through a wage survey process managed by the U.S. Department of Labor (DOL)s Wage and Hour Division (WHD). Currently, the DBA covers approximately $217 billion in federally assisted construction spending each year, providing minimum wage protections for roughly 1.2 million workers across the country.
How the BIL Expands Davis-Bacon Coverage
The Bipartisan Infrastructure Law applies Davis-Bacon labor standards to federally funded or assisted construction projects through three distinct mechanisms:
- Adding Funding to Existing Programs: The BIL increases appropriations for programs already covered by a Davis-Bacon Related Act, such as the Infrastructure for Rebuilding America (INFRA) program and the Drinking Water and Clean Water State Revolving Loan Funds.
- New Programs Under Existing Acts: The law creates new programs, such as the Bridge Investment Program and the Airport Terminal Improvement Program, that fall under the umbrella of existing Davis-Bacon Related Acts.
- Express Provisions in New Programs: The BIL includes provisions that explicitly subject all construction projects receiving funding under particular programs to Davis-Bacon requirements. For example, construction projects assisted by funding under Division D (Energy) are subject to DBA standards.
This three-pronged approach means that contractors working on everything from highway resurfacing to electric vehicle charging infrastructure and clean water projects must comply with prevailing wage requirements. For those overseeing quality assurance on these sites, understanding Construction Site Quality Control and Inspection Methods for regulatory conformance is equally important.
Key Compliance Requirements for Contractors and Subcontractors
Contractors performing work on Davis-Bacon covered projects under the BIL must meet a series of specific obligations. Failure to comply can result in withheld payments, debarment from future federal contracts, and back-wage liability.
Wage Determination and Classification
The foundation of DBA compliance is the wage determination, a document issued by the WHD that lists the prevailing wage rates and fringe benefits for each labor classification in a given geographic area. These determinations are accessible through sam.gov. Contractors must identify the correct wage determination by considering:
- Project Location: Where the work is physically performed determines which wage determination applies.
- Type of Construction: The DOL distinguishes between building, residential, highway, and heavy construction categories, each with its own wage determination.
- Labor Classifications: Workers must be classified according to the work they actually perform, and each classification carries a specific wage rate.
If a worker performs tasks in more than one labor classification during a workweek, the contractor must pay either the highest applicable wage rate for all hours worked or apply different wage rates based on the actual hours worked in each classification. Maintaining accurate records of hours by classification is critical.
Certified Payroll Reporting
Certified payroll reports are the primary mechanism for demonstrating compliance on Davis-Bacon projects. Contractors must submit these reports weekly, within seven days of the payroll date for each workweek. A compliant certified payroll includes:
- Employee name and identifying number
- Classification and hourly wage rate for each worker
- Total hours worked each day and each week
- Gross wages earned
- Fringe benefit contributions made on behalf of each worker
- Deductions and net wages paid
The Standard Form 1444 (SF-1444) and WH-347 are common certified payroll forms accepted by federal contracting agencies. Prime contractors must also ensure that the Davis-Bacon labor standards clauses and applicable wage determinations are incorporated into all subcontracts.
Posting Requirements
Contractors must post the Employee Rights under the Davis-Bacon Act poster and the applicable wage determination at the worksite in a location that is prominent and easily accessible to all workers. This requirement ensures transparency and allows workers to verify they are receiving the correct pay for their classification.
Five Essential Compliance Principles from the Department of Labor
The DOLs Wage and Hour Division has outlined five critical principles that every contractor should understand before bidding on or commencing work under BIL-funded projects. These principles form the operational backbone of Davis-Bacon compliance.
| Principle | Key Requirement | Action Needed |
|---|---|---|
| 1. DBA Applies to Most Federal Construction | Local prevailing wages required on most federal and federally funded contracts | Verify DBA coverage for every project before bidding |
| 2. DBA Projects Require DBA Wages | Workers must receive no less than locally prevailing wages for each classification | Obtain and review the correct wage determination at sam.gov |
| 3. Know the Wages Owed | Pay no less than wages and fringe benefits listed on wage determination | Understand project location, construction type, and labor classifications |
| 4. Certified Payroll Ensures Accuracy | Weekly certified payroll reports verify proper wage payments | Submit SF-1444 or WH-347 within seven days of each payroll date |
| 5. Workers Have Enforcement Rights | Workers can contact the Contracting Officer or WHD with wage concerns | Keep required posters visible and respond promptly to inquiries |
Following these principles protects both contractors and workers. For projects involving environmental compliance, also review Tmdl Compliance for Builders Stormwater Regulations Clean Water standards that may apply to BIL-funded water infrastructure work.
Navigating Compliance Challenges and Enforcement
With the BIL bringing many new contractors and funding recipients under DBA requirements for the first time, the WHD has emphasized both education and enforcement as pillars of its compliance strategy.
Common Compliance Pitfalls
Contractors new to Davis-Bacon work frequently encounter several recurring issues:
- Misclassification of Workers: Assigning workers to a lower-paid classification than the work they actually perform is the most common violation. A laborer performing carpentry work must be paid the carpenter rate, not the laborer rate.
- Incorrect Wage Determination: Using the wrong wage determination for the project location or construction type leads to underpayment. Always verify the determination on sam.gov at the time of bid and again at contract award.
- Late or Incomplete Certified Payrolls: Missing the seven-day submission window or submitting forms with incomplete information can trigger audits and payment withholding.
- Fringe Benefit Accounting Errors: Failing to properly calculate or document bona fide fringe benefit contributions is a frequent source of non-compliance findings.
- Subcontractor Oversight Failures: Prime contractors are ultimately responsible for ensuring all subcontractors comply. Include DBA clauses in every subcontract and verify certified payrolls from lower-tier contractors.
Enforcement and Resources
The WHD has made clear that vigorous enforcement will accompany the BILs historic investment. The agencys enforcement toolkit includes investigating complaints, conducting random compliance checks, withholding contract payments, and debarring contractors from future federal work. The DOL also partners with other federal agencies to share data and coordinate enforcement actions.
To support compliance, the WHD offers annual seminars, online training, and virtual outreach sessions for employers, employees, unions, and other stakeholders. The agency can answer questions or take complaints in over 200 languages. Contractors with questions about prevailing wage determinations or specific project requirements should contact the WHD directly or reach out to the federal agency funding the project.
The Biden administration has also introduced complementary initiatives, including the Good Jobs Initiative, which provides information to improve job quality across the private sector, and an executive order raising the contractor minimum wage to $15 per hour. Enhanced interagency cooperation aims to protect workers from illegal retaliation when they exercise their labor rights. For contractors managing worksite conditions, understanding Open Space Requirements for Ventilation in Buildings Ensuring healthy environments remains relevant across project types.
Developing a Compliance Program
Given the scope of BIL spending and the WHDs enforcement posture, contractors should consider establishing a formal Davis-Bacon compliance program. Key elements include:
- Designating a compliance officer responsible for wage determination review, certified payroll filing, and subcontractor oversight
- Implementing timekeeping systems that track hours by labor classification and project
- Conducting internal audits of payroll records before submission to contracting agencies
- Providing training for project managers, foremen, and payroll staff on DBA requirements
- Maintaining organized records for a minimum of three years after project completion, as required by DOL regulations
A proactive compliance program not only reduces the risk of violations but also strengthens a contractors position when competing for BIL-funded work. Many federal and state agencies now evaluate past compliance history as part of the contractor qualification process.
The Bipartisan Infrastructure Law represents once-in-a-generation investment in Americas infrastructure, and with it comes responsibility to ensure workers are paid fairly for their labor. Contractors who invest the time to understand Davis-Bacon requirements, build robust compliance systems, and stay current with DOL guidance will be well positioned to succeed in the expanding federal infrastructure market. The stakes are high, but the tools and resources are available for those who take compliance seriously.
