Prevailing Wage Isn't an Average. It's the Rate Most Electricians Get Paid.

If you have bid or worked a publicly funded commercial job, you have seen a wage determination attached to the front of the contract documents: a sheet listing an hourly rate and a separate fringe amount for "Electrician" in one particular county. The question most electricians ask the first time they see it is where that number came from. It is not a survey average of what everybody in town makes, and it is not the local union scale copied over. It is the output of a specific legal test.

The Davis-Bacon Act requires contractors and subcontractors on federally funded or federally assisted construction contracts over $2,000 to pay no less than the locally prevailing wages and fringe benefits for similar work in the area. The Department of Labor's Wage and Hour Division decides what prevailing means using a three-step hierarchy. If more than 50 percent of the electricians on similar projects in the area are paid the same rate, that rate prevails. If no rate holds a majority, the rate paid to the greatest number prevails, provided that group is at least 30 percent of those employed. Only when neither threshold is met does the determination fall back to a weighted average.

Area means the city, town, county, or other civil subdivision where the work is performed, so one contractor can owe two different electrician rates on jobs forty miles apart. The determination that applies is the one in effect when the contract is awarded, and it generally stays fixed for the life of that contract. If a job needs a classification the determination does not list, the contractor has to request a conformance from the Wage and Hour Division, which checks whether the work is already covered by a listed classification, whether the proposed classification matches area practice, and whether the proposed rate bears a reasonable relationship to the rest of the sheet. That review generally takes about 30 days.

The rate arrives in two pieces, and both are owed. The base is cash in the check. The fringe figure covers irrevocable contributions to a bona fide benefit fund, such as health insurance, pension, or vacation. Legally required payments like Social Security and workers' compensation do not count toward it. Apprentices may be paid below the journey-level rate only if they are registered in a Department of Labor approved program and kept within that program's approved ratio. An unregistered helper, or an apprentice beyond the allowed ratio, owes the full electrician rate for every hour worked.

The common misconception is that prevailing wage is union scale under another name. The two often land close, because the majority test tends to pick up a negotiated rate wherever organized contractors do most of the area's work. But the test is arithmetic, not affiliation, and in some counties the majority rate is an open-shop rate. The second misconception is that prevailing wage follows large projects. It follows public money. A privately financed data center owes no federal prevailing wage unless federal funding or assistance attaches to it.

If you are weighing a prevailing wage job against private commercial work, compare base plus fringe against the private package in full rather than the base rate alone. For how those numbers compare across markets and experience levels, see the AmpScouts Commercial Electrician Salary Guide.
