If your company takes federal construction work, the Davis-Bacon Act shapes how you pay your crew and what you report every week. In plain terms, it requires contractors and subcontractors on federally funded construction to pay workers at least the local prevailing wage, including fringe benefits. A whole family of laws known as the Related Acts extends that same requirement to most federally assisted projects, from highways to water treatment plants.
The stakes are real. Get it right and you can bid federal work with confidence and keep your crew paid correctly. Get it wrong and you are looking at back wages, withheld payments, and in serious cases, debarment from future federal contracts.
This guide walks through the whole picture: what the act is, the Related Acts and other laws that travel with it, who has to comply, what you owe and report, the penalties for falling short, the state versions you also have to watch, and what the 2023 rule update changed for everyone working federal jobs today.

What is the Davis-Bacon Act?
The Davis-Bacon Act is a 1931 federal law that requires contractors and subcontractors on federally funded or federally assisted construction projects to pay their laborers and mechanics at least the locally prevailing wage and fringe benefits.
It was passed during the Great Depression for a straightforward reason: to keep contractors from winning federal bids by undercutting local wage standards. Nearly a century later, that purpose still holds.
Here is what it covers:
- Threshold and scope. The act applies to federal contracts over $2,000 for the construction, alteration, or repair of public buildings or public works. That includes painting and decorating, not just new builds.
- Prevailing wage. This is the combination of a basic hourly rate and fringe benefits, listed in the wage determination that applies to your contract. It is owed for all hours worked on the site of the work.
- How you can pay it. You can meet the obligation entirely in cash wages, through bona fide fringe benefits, or with a combination of the two.
The "prevailing" wage is the rate that prevails for a given type of work in a given area, set by the U.S. Department of Labor. We will come back to how that rate is calculated, because the 2023 rule changed it.
What Are the Davis-Bacon Related Acts?
The Davis-Bacon Related Acts are the roughly 60 to 70 federal statutes that extend Davis-Bacon prevailing wage standards to construction funded or assisted through grants, loans, loan guarantees, and insurance. In other words, when federal dollars reach a construction project through one of these programs, Davis-Bacon labor standards usually come along with them.
Recognizable examples include:
- The Federal-Aid Highway Acts, for road and bridge construction
- The Housing and Community Development Act, for HUD-funded projects
- The Federal Water Pollution Control Act (the Clean Water Act), for wastewater treatment facilities
- Airport and airway development funding, for aviation construction
- Copeland "Anti-Kickback" Act, Bars a contractor or subcontractor from pressuring a worker to give back any part of the pay they have earned.
The practical takeaway: it is usually the type of federal funding, not the type of work, that determines which act applies to your contract. When in doubt, check the act cited in your contract documents.
Other Federal Labor Laws That Travel With Davis-Bacon
A handful of other laws often come up on the same projects. These are not technically Related Acts, but you will run into them, so it helps to know what each one does:
- Contract Work Hours and Safety Standards Act (CWHSSA). Requires overtime at one and a half times the basic rate for hours over 40 in a week on covered contracts, a requirement commonly tied to contracts over $100,000.
- Walsh-Healey Public Contracts Act. Sets wage, hour, and safety standards for federal contracts over $15,000 to manufacture or supply goods.
- McNamara-O'Hara Service Contract Act. The service-work counterpart to Davis-Bacon, requiring prevailing wages and fringe benefits on federal service contracts over $2,500.
There are also federal executive orders covering contractor minimum wage and paid sick leave. These are contractor labor standards that sit alongside Davis-Bacon rather than being part of the Related Acts themselves, so treat them as separate obligations to confirm for your specific contract.
Who Has to Comply?
Compliance falls on contractors and subcontractors performing covered work on federal or federally assisted construction projects, at every tier of the job. The laborers and mechanics doing manual or physical work on-site are covered, while professionals, administrative staff, and certain supervisors are exempt. For the full breakdown, see our guide to who is and isn't covered by the Davis-Bacon Act.
Davis-Bacon Payment and Reporting Requirements
Once you know a project is covered, the day-to-day obligations are fairly clear:
- Pay the prevailing wage, base rate plus fringe, for all hours worked on-site.
- Pay your workers weekly.
- Submit weekly certified payroll on Form WH-347, with a signed Statement of Compliance.
- Record each worker's name, job classification, hourly rate, hours worked, and the amounts actually paid.
- On contracts over $100,000, pay CWHSSA overtime at one and a half times the basic rate for hours over 40 per week.
- Post the applicable wage determination and the Davis-Bacon poster at the jobsite where workers can see them.
Apprentices and trainees enrolled in a registered Department of Labor program can be paid the program's rates rather than the full prevailing wage, but they still have to appear on your weekly report.
None of these steps is complicated on its own. The difficulty is doing all of them accurately, every week, across every worker and every sub.
Penalties for Non-Compliance
When violations are found, the consequences add up quickly. Depending on the severity, a contractor can face:
- Back wages owed to underpaid workers
- Withholding of contract payments, and cross-withholding from your other federal contracts
- Contract termination
- Debarment from federal contracts for up to three years
- Criminal exposure for willful falsification of payroll records
You do have a path to challenge findings. Contractors can contest a violation before an Administrative Law Judge, then appeal to the Department's Administrative Review Board, and ultimately to the federal courts. That said, the cleaner route is to classify workers and file reports correctly the first time, because fixing a violation after the fact almost always costs more than preventing one.
State "Little Davis-Bacon" Acts
Federal law is not the whole story. More than 30 states have their own prevailing wage laws, often called "Little Davis-Bacon" acts, that apply to state-funded projects. Each state sets its own thresholds, rates, and rules.
The part that matters most on the ground: when a project carries both federal and state funding, you have to comply with both sets of requirements, and where they differ, the more stringent one usually wins. In practice, that often means paying the higher of the two wage rates. Our state-by-state prevailing wage resource breaks down the rules where you work.
How the Law Changed: The 2023 Final Rule
For years, contractors heard that big changes to Davis-Bacon were coming. They arrived. In 2023, the Department of Labor finalized the first comprehensive update to Davis-Bacon in roughly 40 years, and it took effect on October 23, 2023. Here is what actually changed, without the political noise.
- Prevailing wages are calculated differently now. The rule restored the older "three-step" method, including what is known as the 30% rule. When no single wage rate is paid to a majority of workers in a classification, a rate paid to at least 30% of them is treated as prevailing. Only when neither of those applies does the weighted average kick in. This is the change earlier coverage described as merely proposed, and it tends to push wage determinations higher in many areas.
- Modern construction is clearly covered. The update modernized the definitions so that work like installing solar panels, wind turbines, broadband, and electric vehicle chargers falls squarely within Davis-Bacon.
- Enforcement got stronger. The rule added anti-retaliation protections and "make-whole" relief for workers, such as back pay and reinstatement.
- Primes are on the hook for subs. Under the new flow-down and cross-withholding provisions, prime contractors can be held liable for back wages owed by their subcontractors. That makes monitoring your entire contractor chain a genuine responsibility, not a formality.
- Wage-setting is more flexible. The Department can now adopt qualifying state and local wage rates and issue multi-county determinations, with more frequent updates so rates do not go stale.
A few provisions are currently on hold. A June 2024 nationwide court injunction paused several pieces of the rule, including the narrowed material-supplier and delivery-driver definitions and the "operation of law" provision. Because that status can change, confirm where things stand before relying on any of the paused provisions on an active project.
One more piece of context. Infrastructure funding from laws like the IIJA, the IRA, and the CHIPS Act has pushed a wave of new work under Davis-Bacon. More projects carry these obligations now than did a few years ago, which means these rule changes reach more contractors than ever.

FAQs
They are the roughly 60 to 70 federal statutes that extend Davis-Bacon standards to federally assisted construction, including highway, HUD housing, water, and airport projects.
Davis-Bacon is the federal prevailing wage law. Most states also have their own prevailing wage laws that work alongside it.
It restored the three-step "30% rule" for setting prevailing wage, expanded coverage to modern construction like solar and EV chargers, strengthened enforcement, and made prime contractors liable for subcontractor violations.
When no wage rate is paid to a majority of workers in a classification, a rate paid to at least 30% of them becomes the prevailing wage. If that cannot be met either, the weighted average is used.
