The Davis-Bacon Act is the law that sets minimum wages on federal construction. If you're bidding, working on, or subcontracted to a federally funded project, you're subject to it. There's no small-contractor exemption. There's no "I didn't know" defense.
Here's what it is, when it applies, what it requires, and what happens when you don't follow it.
That's the whole thing in one paragraph. The rest of this page is the details.
The Davis-Bacon Act was signed in 1931 by Herbert Hoover. It's named after Senator James Davis (PA) and Representative Robert Bacon (NY).
The backstory: during the Depression, contractors would underbid each other on federal projects by bringing in cheaper out-of-state labor. Local workers got priced out of work in their own communities. The law was designed to stop that — contractors have to pay local prevailing wages, so they can't win bids by importing underpaid workers.
The law has been amended several times since 1931, most significantly with the Copeland "Anti-Kickback" Act (1934), the Contract Work Hours and Safety Standards Act (1962), and the major 2023 DOL regulatory overhaul that updated how prevailing wages are calculated.
Whether you agree with the policy or not, it's been the law for nearly a century. Federal construction doesn't happen without it.
Three conditions trigger Davis-Bacon. If all three are met, you're in.
Watch out for pass-through subs
If you're a sub to a sub to a sub on a federal project, Davis-Bacon still applies to you. Coverage flows down the contract chain. Check your subcontract for the Davis-Bacon clause — it's always there on federal work.
Four things you have to do on every Davis-Bacon project.
The DOL's Wage and Hour Division conducts wage surveys by county and project type. Contractors and unions submit data showing what they actually paid on recent projects. DOL analyzes it and publishes the prevailing rate for each classification.
Here's the methodology in brief:
The original Davis-Bacon Act covers direct federal contracts. But Congress has passed 60+ other statutes that extend prevailing wage requirements to federally-assisted projects — things Congress wanted built with federal money but administered through grants, loans, or guarantees rather than direct contracts.
These are the Davis-Bacon Related Acts. If you're on any of these, the same prevailing wage, certified payroll, and recordkeeping rules apply.
Common DBRAs you'll see:
If your contract references 40 U.S.C. Chapter 31 or includes a "Davis-Bacon clause," DBRA applies. When in doubt, ask your contracting officer.
Davis-Bacon enforcement is serious. The DOL Wage and Hour Division has broad investigative authority and works closely with contracting agencies. Consequences scale with the violation.
Ten years ago, Davis-Bacon compliance meant spreadsheets, binders, and calling the DOL to ask questions. Today, most mid-sized contractors use a stack of tools to stay compliant without burning out their office staff.
CertifiedPayrollPro integrates with common payroll providers, validates wage rates automatically, stores everything for audit retrieval, and uses Lydia (our AI compliance assistant) to catch issues before submission. That's the modern stack.
It's a federal law that requires contractors on federally funded construction projects to pay workers a minimum wage rate set by the DOL for that area. The goal is to stop contractors from winning bids by underpaying local workers.
Davis-Bacon applies to federal construction contracts over $2,000. That threshold hasn't changed since 1935. Basically every real federal construction project triggers it.
The U.S. Department of Labor's Wage and Hour Division (WHD). They investigate complaints, conduct audits, and can assess back wages, penalties, and debarment. Contracting agencies (GSA, Army Corps, HUD, etc.) also monitor compliance on their projects.
The original Davis-Bacon Act covers direct federal construction. Davis-Bacon Related Acts (DBRAs) are 60+ separate federal statutes that extend prevailing wage requirements to federally-assisted projects — things funded by federal grants, loans, or guarantees. HUD, DOT, EPA, and others all administer DBRAs.
No. You can pay the base hourly rate in cash plus fringe benefits into approved plans (health insurance, pension, apprenticeship). Or you can pay everything in cash. As long as the total meets the wage determination, you're compliant.
A DOL-published list of minimum wage rates for each labor classification (Carpenter, Electrician, Laborer, etc.) in a specific county and project type (building, heavy, highway, residential). Your contract is tied to a specific WD number. You can look them up on SAM.gov.
The DOL assesses back wages for every hour underpaid. They can also withhold contract payments to cover it, assess liquidated damages for overtime violations, and debar you from federal work for 3 years. Willful violations can trigger criminal referral.
Yes. Weekly WH-347 certified payroll reports are mandatory on every federal construction contract subject to Davis-Bacon. No exceptions. Miss the weekly deadline and the contracting agency can withhold progress payments.
No. State prevailing wage laws (sometimes called 'little Davis-Bacon' laws) are separate. California DIR, New York DOL, Illinois IDOL, and others publish their own rates — often higher than federal. If a project is both federal and state, you pay the higher of the two for each classification.
Minimum 3 years after the project is completed. That includes timecards, certified payrolls, paystubs, wage determinations, and subcontractor payroll records. Some states require longer — California requires 3 years from project acceptance.
CertifiedPayrollPro validates every worker's pay against the wage determination, generates compliant WH-347s, and keeps a 3-year audit trail automatically.
