TL;DR

Prevailing wage is the minimum rate that contractors and subcontractors must pay workers on federally funded construction and service projects - set by the Department of Labor and designed to prevent federal contracts from undercutting local wage standards.

What Prevailing Wage Means

The US government spends hundreds of billions of dollars each year on contracts, and prevailing wage laws determine the floor for what workers on those contracts get paid. The concept has two primary statutory expressions: the Davis-Bacon Act for construction projects and the Service Contract Act (now the Service Contract Labor Standards) for service contracts.

The Davis-Bacon Act, passed in 1931, requires that contractors on federally funded or federally assisted construction projects pay workers the "prevailing wage" for the locality - defined as the wage paid to the majority of workers in a particular trade in a specific geographic area. The Department of Labor determines prevailing wage rates through periodic wage surveys. These rates are published in wage determinations and incorporated into federal contracts as mandatory terms.

The Service Contract Act covers contracts primarily for services - janitorial, food service, security, IT support, and similar work performed at federal facilities. It operates on the same principle: workers must receive at least the local prevailing wage for their job classification.

Wage determinations are specific: a journeyman electrician on a federal construction project in Los Angeles has a different prevailing wage than one in rural Mississippi. The rates include both base wages and fringe benefits - health insurance, retirement contributions, and other benefits count toward meeting the prevailing wage requirement, which means a contractor offering rich benefits can pay a slightly lower base wage and still comply.

Violations can result in debarment from future federal contracts, back pay to workers, and contract termination. The enforcement mechanism includes contractor-submitted certified payrolls that contracting officers review.

Why It Matters for Recruitment

If your organization is a federal contractor or subcontractor, or you are recruiting for one, prevailing wage is not background knowledge - it is a core constraint in how roles are structured, budgeted, and filled. Misclassifying a worker into the wrong job classification (and therefore paying the wrong prevailing wage rate) is a common source of compliance failures and subsequent debarment actions.

For recruiters working in federal contracting environments, prevailing wage determines what you can offer candidates. You cannot negotiate below the wage determination for a covered role, and candidates who expect market rates need to understand how their compensation is structured (base plus fringe). The classification system matters - a computer systems analyst and a general IT support technician have different wage determinations, and the distinction is not always obvious from a job description.

State prevailing wage laws add another layer. Most states have their own prevailing wage statutes covering state-funded projects. Some mirror federal requirements; others are stricter. California's prevailing wage law, for example, applies to a broader range of project types and uses different rate-setting methodology than Davis-Bacon.

Executive Order 13658 (2014) and subsequent executive orders have periodically raised the minimum wage floor for federal contractors above the federal statutory minimum wage, adding another variable that affects what contractors must pay and therefore what recruiters can offer.

In Practice

A mid-size facilities management company wins a five-year federal contract to provide janitorial and food service work at a government campus in Virginia. The contract is covered by the Service Contract Act. Before posting any jobs, their HR team must pull the wage determination for Fairfax County, Virginia, covering the relevant job classifications.

The wage determination specifies that janitors must be paid $18.75 per hour plus $5.36 in fringe benefits. The company's standard janitorial wage is $16.50 per hour with a health insurance contribution worth $3.00 per hour. Both the wage and the fringe fall short of the prevailing wage requirement.

They adjust: raise the base to $18.75 and restructure the benefits contribution to meet the $5.36 fringe requirement. Total labor cost per janitor increases by $4.61 per hour - a number that was supposed to have been factored into the contract bid. It was not. The resulting margin compression costs the company $280,000 over the contract's first year.

The lesson is straightforward: prevailing wage rates must be pulled and modeled before the bid goes in, not after the contract is won.
