Davis-Bacon Wages, Explained Without the Legal Fog

If you do federal construction, you will hit Davis-Bacon, and it will cost you money if you don't understand it up front. So let me strip the legal fog off it.

Davis-Bacon is simple at its core: on federal construction jobs, the government doesn't let you pay whatever the market will bear. It publishes a wage determination for the job — what each classification of worker, the carpenters, the electricians, the laborers, has to be paid, including fringe benefits. You can't pay less, even if you can find people who'd work for less. It's the federal government setting the floor, and the floor is usually close to, or above, union scale.

The mistake I see over and over is contractors finding out about Davis-Bacon after they've already priced the job with their normal labor rates. The wage rates are in the solicitation. Read them before you bid, not after. The clauses are there, the wage determination is attached, and the Department of Labor will be checking. When a contractor tells me they lost money on their first federal job, almost always the story includes the sentence, I didn't know they had to pay themselves the Davis-Bacon wages.

Then there's the paperwork, and this is the part nobody warns you about: certified payroll. Every week, on the right form, you report what every worker on the job was paid, in the correct classification, with the right fringe numbers. And you don't just keep it in a drawer — it gets submitted to the government, and your subcontractors have to do it too. If a sub's certified payroll is wrong or late, it's your problem, because the government holds you responsible for the whole job's compliance.

How do you not lose money to Davis-Bacon? Three habits. First, price every classification at the wage determination rate, plus your real burden, before you ever add your margin. Second, make certified payroll a weekly routine, not a scramble — the day your first payroll runs, the process is in place, because a late certified payroll is a compliance finding waiting to happen. Third, educate your crew leads: when a worker does more than one kind of work, the time has to be split by classification. Guessing at classifications is how innocent contractors end up owing back wages.

None of this is optional, and none of it is secret. It's in the solicitation, and it's enforced by the Department of Labor. The contractors who do well with Davis-Bacon aren't the ones with clever accountants. They're the ones who read the wage determination on day one and built it into the price on day two.
