What happens during a DOL prevailing wage audit is that the Department of Labor reviews your certified payroll, worker classifications, wage rates, and supporting documentation to confirm compliance with the Davis-Bacon Act.
For construction payroll teams, this directly impacts compliance risk, project timelines, and cost exposure. Even small mistakes can lead to back wage payments, penalties, or delays. Audits often happen with little warning and focus heavily on documentation accuracy and consistency.
Understanding the audit process helps your team stay prepared, reduce risk, and respond quickly when records are requested.

A DOL prevailing wage audit is typically triggered by worker complaints, random selection, prior violations, or inconsistencies in certified payroll reports.
You must provide certified payroll reports, timecards, wage determinations, employee classifications, fringe benefit records, and proof of wage payments.
The Department of Labor generally reviews records going back up to three years, depending on the scope of the investigation.
If violations are found, the DOL may require back wage payments, impose penalties, and in serious cases, pursue debarment from future federal contracts.
