Compliance Guide
Davis-Bacon, Explained and Administered
The Davis-Bacon Act of 1931 and its Related Acts (DBA/DBRA) require contractors on covered federal and federally assisted construction to pay at least the locally prevailing wages and fringe benefits the U.S. Department of Labor determines. This page explains how that machinery actually works — for owners, for workers, and for the people auditing the money — with links to every primary source. It is what Nevantin runs in-house on covered work.
The Basics
| Statute | Davis-Bacon Act of 1931, 40 U.S.C. §3141 et seq.; roughly 70 "Related Acts" extend it to federally assisted programs — including BEAD broadband and much IIJA-funded utility work |
|---|---|
| Coverage trigger | Federal construction contracts over $2,000, and assisted construction under a Related Act — see DOL WHD's construction contracts page |
| The wage floor | The wage determination attached to the contract: DOL-published minimum rates and fringes per labor classification, per county, per construction type |
| The proof | Form WH-347 certified payroll, submitted weekly with a signed Statement of Compliance — false statements are prosecutable |
| Deductions | The Copeland "Anti-Kickback" Act (29 CFR Part 3) polices what may be withheld from covered workers' pay |
| The rulebook | 29 CFR Part 5 — the operative regulations, substantially updated by DOL's 2023 modernization rule |
| Enforcement | U.S. Department of Labor, Wage and Hour Division; remedies run from back wages through contract withholding to debarment |
How a Covered Job Actually Runs
The wage determination attaches at award
The contracting agency incorporates the current SAM.gov wage determination for the place and type of construction. That document — not the contractor's judgment — sets the minimum hourly rate and fringe for every classification on the job.
Every worker is classified against it
Workers are matched to the determination's labor classifications by the work they actually perform. When a needed classification doesn't exist, the contractor requests a conformance (Standard Form 1444) through the agency to DOL — before the work, not after.
Fringes are paid in cash or bona fide plans
The fringe component may be paid as cash on the check or as contributions to bona fide benefit plans — and the split is reported line by line. DOL Fact Sheet #66 is the concise official summary of these obligations.
Apprentices work within registered-program ratios
Apprentices may be paid their program's schedule below journey rates only while enrolled in a program registered with DOL's Office of Apprenticeship or a state agency (see apprenticeship.gov) and employed within its ratio; outside those bounds, journey wages are owed.
Certified payroll goes in weekly
Each week the contractor submits WH-347 (or its equivalent) with a signed Statement of Compliance covering every covered worker, classification, hours, rate, fringes, and deductions. Primes collect and review their subcontractors' payrolls — the obligation flows down every tier, and the prime answers for all of them.
Posting and records complete the loop
The wage determination and the DOL "Employee Rights" poster (WH-1321) go up at the site; payroll records are retained and open to the agency and DOL. On audit, the records are the compliance.
Where You Fit
Project owners & grant recipients
Your funding agreement almost certainly flows Davis-Bacon down to every construction contract. Your exposure is your contractor's paperwork: weekly certified payrolls, correct classifications, conformances filed before disputed work.
- Verify the wage determination in your contract matches SAM.gov current
- Require payroll submission as a pay-app condition
- On BEAD money, see our BEAD guide for the full stack
Workers & apprentices
On a covered job you are owed at least the posted determination's rate and fringe for your classification — check the poster on site, and check your stub against it.
- Look up rates yourself at sam.gov/wage-determinations
- Apprentice rates are only legal within a registered program and its ratio
- Complaints go to DOL Wage and Hour — retaliation is prohibited
Lenders, investors & administrators
Davis-Bacon failures convert into withheld contract funds, back-wage liability, and debarment — which is to say, schedule and repayment risk. Underwrite the compliance machinery, not the assurance.
- The operative rules: 29 CFR Part 5
- DOL's Prevailing Wage Resource Book is the audit-grade reference
- Ask any contractor to show a real WH-347 package, not a policy statement
What Nevantin Runs
Nevantin Services administers Davis-Bacon compliance in-house on covered work as standard mobilization, not an add-on: WH-347 certified payroll weekly from the first payroll of the job, wage determinations applied per contract, classification and conformance handling, fringe reporting line by line, apprentices within registered-program ratios, site postings, and retained records organized for the agency's auditor.
On jobs where we are prime, subcontractor certified payrolls are collected and reviewed before submission — because the flow-down makes them ours to answer for. The same machinery carries IRA Prevailing Wage & Apprenticeship work and BEAD-funded builds.
