Kentucky Public Works Contractor Rules and Prevailing Wage

Kentucky public works contracting operates under a distinct regulatory framework that separates government-funded construction from private sector work in both bidding requirements and wage obligations. Contractors performing work on state-funded infrastructure, public buildings, and municipal projects must satisfy procurement, licensing, and labor compensation standards that do not apply to private residential or commercial jobs. Understanding where these obligations begin — and where they end — is essential for any contractor seeking to participate in Kentucky's government construction market.

Definition and scope

Public works contracting in Kentucky refers to construction, alteration, repair, or maintenance performed on projects funded in whole or in part by state, county, or municipal government appropriations. The Kentucky Finance and Administration Cabinet oversees capital construction procurement for state-funded projects, while individual counties and municipalities administer their own public procurement processes subject to Kentucky Revised Statutes (KRS) Chapter 45A, the Kentucky Model Procurement Code (Kentucky Legislature, KRS Chapter 45A).

Scope coverage: This page addresses Kentucky state law obligations for contractors on publicly funded projects within Kentucky's geographic jurisdiction.

Scope limitations: Federal-aid projects — including federally funded highway construction administered through the Kentucky Transportation Cabinet — trigger federal Davis-Bacon Act prevailing wage requirements rather than, or in addition to, state provisions. Projects funded exclusively with private capital are not covered by public works bidding or wage rules, even when the owner is a nonprofit or quasi-public entity. Work performed in neighboring states (Tennessee, Virginia, West Virginia, Ohio, Indiana, Missouri) falls outside this page's scope entirely.

For broader classification context, the Kentucky Contractor License Types page identifies which license categories are eligible for public work.

How it works

Competitive bidding requirements

KRS Chapter 45A requires that state agency construction contracts exceeding $30,000 be awarded through competitive sealed bidding (Kentucky Finance and Administration Cabinet). Contractors must submit sealed bids that include:

1. A completed bid form specifying unit prices or lump-sum totals.
2. Proof of applicable licensure from the Kentucky Department of Housing, Buildings and Construction (/kentucky-department-of-housing-buildings-construction).
3. A bid bond, typically 5% of the total bid amount, issued by a surety licensed in Kentucky.
4. Evidence of workers' compensation insurance meeting KRS 342 requirements (/kentucky-contractor-workers-compensation-requirements).

Awards go to the lowest responsive, responsible bidder. "Responsive" means the bid conforms materially to solicitation requirements; "responsible" means the contractor has demonstrated financial capacity, technical expertise, and satisfactory prior performance.

Prevailing wage

Kentucky maintained a state prevailing wage law — the Kentucky Prevailing Wage Act — under KRS 337.505 through 337.550 for decades. In 2017, the Kentucky General Assembly repealed those statutes, eliminating the state-level prevailing wage mandate for most public construction work (Kentucky Legislature, 2017 HB 3). As a result, no state-administered wage schedule applies to the majority of Kentucky public works projects funded solely by state or local appropriations.

Critical contrast — state vs. federal funding:

Contractors bidding on federally assisted projects must obtain applicable wage determinations from the U.S. Department of Labor Wage and Hour Division and post wage determinations at the job site. Violations carry back-pay liability and potential debarment from future federal contract work.

Common scenarios

State highway resurfacing contract: A contractor awarded a Kentucky Transportation Cabinet paving contract funded through the Federal Highway Administration must comply with Davis-Bacon wage rates. The Transportation Cabinet issues bid packages that include the applicable federal wage determination as an exhibit.

County courthouse renovation: A county-funded renovation project with no federal dollars involved falls under county procurement rules and KRS 424.260 (public notice requirements) but carries no mandatory wage floor under current Kentucky law. The Kentucky Contractor Bid and Contract Requirements page addresses contract formation obligations.

Municipal water system expansion: If the project uses EPA Clean Water State Revolving Fund money, Davis-Bacon related act wage requirements attach even though the contracting entity is a local utility authority.

Subcontractor participation: Prime contractors on public projects remain responsible for their subcontractors' compliance with bid terms, insurance requirements, and any applicable wage obligations. The relationship between prime and sub on public projects is addressed further at Kentucky General Contractor vs Subcontractor.

Decision boundaries

The threshold questions that determine a contractor's obligations on any Kentucky project:

• Is the project funded by federal dollars, state dollars, or local dollars — or a combination? Federal funding triggers Davis-Bacon; state or local funding alone does not trigger a wage floor under current Kentucky law.
• Does the project value exceed $30,000? Below that threshold, state agency contracts may use simplified acquisition procedures rather than competitive sealed bidding.
• Is the contractor properly licensed for the work type? Electrical, plumbing, HVAC, and other specialty work on public projects requires the same trade-specific licenses required on private work — see Kentucky Electrical Contractor Licensing and Kentucky Plumbing Contractor Licensing.
• Are there local procurement ordinances that impose additional requirements? Louisville Metro Government and Lexington-Fayette Urban County Government each maintain procurement regulations that may exceed state minimums.
