What is prevailing wage in construction?

Prevailing wage is the minimum hourly wage and fringe benefit package that must be paid to laborers and mechanics on covered public construction projects, based on the rates paid for similar work in the area.

Prevailing wage is a pay floor for public construction. When a job is covered, each worker must be paid at least the published rate for their classification and county, including fringe benefits. The rates come from a wage determination attached to the contract. At the federal level, the rule comes from the Davis-Bacon Act. Many states and some cities have their own prevailing wage laws for state and local public work, with their own rates, thresholds, and forms.

For a contractor, prevailing wage changes three things: how you price labor, how you run payroll, and how much paperwork goes to the agency every week.

Federal rules in brief

  • Coverage: the Davis-Bacon Act covers federal or District of Columbia contracts over $2,000 for construction, alteration, or repair of public buildings or public works, including painting and decorating.
  • Related Acts: the same requirements extend to many projects funded with federal grants, loans, loan guarantees, or insurance.
  • Wages and fringes: workers must get at least the prevailing wage and fringe benefits for their classification. The total can be paid all in cash or as cash plus bona fide fringe benefits.
  • Hours covered: prevailing wages, including fringes, apply to all hours worked on site.
  • Payroll reporting: contractors submit weekly certified payroll to the contracting agency.
  • Posting: the wage determination and the Davis-Bacon poster (WH-1321) must be posted at the site where workers can see them.
  • Overtime: on prime contracts over $100,000, the Contract Work Hours and Safety Standards Act requires 1.5 times the basic rate for hours over 40 in a workweek.

A worked example

Say an electrical sub is bidding a federally funded water treatment plant. To keep the math simple, assume the wage determination in the bid documents lists $40.00 base plus $20.00 fringe per hour for electricians in that county (made-up numbers; real rates vary by area and change over time). The sub normally pays its electricians $36.00 an hour, and its health and retirement plans cost $12.00 per hour worked.

To comply, the sub raises base pay by $4.00 to $40.00 and pays the $8.00 gap between its $12.00 of fringes and the required $20.00 in cash on each check. That is $12.00 more per hour before burden. That $12.00, plus the payroll taxes and labor burden on the added cash wages, has to be in the bid. A sub that prices the job at its normal shop rate will lose money on every hour.

Common mistakes

  1. Using the wrong wage determination. The one in the contract controls, not the latest one online.
  2. Misclassifying workers. A laborer doing electrician work must be paid as an electrician for those hours.
  3. Taking fringe credit for benefits that do not qualify or are not paid on all hours.
  4. Late or incomplete certified payroll, which can hold up payment to the whole job.
  5. Ignoring state rules. A state-funded job may carry state prevailing wage requirements even with no federal money.

Frequently asked questions

Who sets prevailing wage rates?

For federal projects, the U.S. Department of Labor issues wage determinations by area and classification. State prevailing wage rates are set by the state labor agency under state law.

Does prevailing wage apply to private jobs?

Generally no. It applies to covered public projects and to some privately run projects that receive government funding. Check the contract and the funding source.

Can fringe benefits be paid as cash?

Yes. Under Davis-Bacon, the prevailing wage and fringe can be met with cash wages, bona fide fringe benefits, or a combination.

How often is certified payroll due on federal jobs?

Weekly, submitted to the contracting agency, typically through the prime contractor.
