The Davis-Bacon Act applies to contracts over $2,000 to which the federal government or the District of Columbia is a party, for the construction, alteration or repair of public buildings or public works. The Related Acts extend the same requirement to construction that is federally assisted through grants, loans or guarantees, which is how most state and local projects end up covered. Within a covered project, every laborer and mechanic performing work on the site is covered — including subcontractors' employees and working owners — regardless of the size of any individual subcontract.
The federal contract test
Davis-Bacon coverage under the Act itself needs three things: a contract in excess of $2,000, the federal government or District of Columbia as a party, and construction, alteration or repair of a public building or public work.
The $2,000 threshold applies to the prime contract, not to individual subcontracts. Once the prime is covered, a $600 subcontract on that project is covered too.
Federally assisted projects: the Related Acts
Most covered projects are not direct federal contracts. Dozens of statutes — the Related Acts — attach Davis-Bacon requirements to construction funded through federal grants, loans, loan guarantees and insurance. Housing, transportation, water infrastructure, energy and broadband programs all carry them.
This is why a city water treatment upgrade or a school built with federal assistance can be a Davis-Bacon job even though the contract is with a local authority. Recent infrastructure and clean energy legislation expanded the set of programs that carry these requirements substantially.
Which workers are covered
| Role | Covered? |
|---|---|
| Laborers and mechanics on the site of the work | Yes — this is the core coverage. |
| Subcontractors' employees at any tier | Yes. |
| Working owners and owner-operators | Yes, for the hours they perform covered manual work. |
| Apprentices and trainees | Yes, at program rates only if registered in an approved program. |
| Truck drivers | For time spent on the site of the work. Delivery-only drivers from a material supplier are generally not covered. |
| Salaried supervisors and executives | Not for supervisory time. Covered for any substantial manual work they perform. |
| Office and administrative staff off site | No. |
| Material suppliers who do no site work | No. |
The "site of the work" boundary
Coverage is geographic as well as contractual. The site of the work is the physical place the building or work will remain, plus adjacent or nearby dedicated facilities set up specifically for the project — a batch plant, borrow pit or tool yard established for that job and near it.
A permanent commercial facility that serves the general public is not the site of the work, even if it supplies the project. That is the line that separates a covered on-site truck driver from an uncovered material delivery.
Coverage now attaches by operation of law
Under the Department of Labor's 2023 final rule, effective 23 October 2023, Davis-Bacon contract clauses and the applicable wage determination are incorporated into covered contracts by operation of law — that is, they apply even if the contracting agency left them out of the contract document.
The practical consequence is that "the clause was not in our contract" stopped being a defence. If the project is covered, the obligation exists.
State and local layers
Federal coverage is only one layer. Roughly thirty states plus the District of Columbia have their own prevailing wage laws applying to state-funded public works, with their own thresholds, their own rate schedules and their own reporting systems. Some cities and counties add a third layer.
Where more than one applies, the general rule is that the higher rate governs and both sets of reporting obligations stand. Complying with the federal determination does not discharge a state filing requirement.
Frequently asked questions
Does the $2,000 threshold apply to my subcontract?
No. The threshold applies to the prime contract. If the prime contract is covered, subcontracts of any size on that project are covered.
Are truck drivers covered by Davis-Bacon?
Drivers are covered for time spent on the site of the work — hauling within the site, or more than incidental time on it. Drivers from a material supplier who deliver and leave are generally not covered. The distinction is time on site, not who employs the driver.
I own the company and I work on the tools. Do I have to pay myself prevailing wage?
Working owners are laborers and mechanics for the hours they perform covered manual work, and those hours belong on the certified payroll. Ownership is not an exemption.
Does Davis-Bacon apply to purely private projects?
No. It applies to federal contracts and to federally assisted construction. A privately financed project with no federal funding and no state prevailing wage law is not covered — but check whether federal assistance reaches the project indirectly through a grant or guaranteed loan.
