Missouri prevailing wage law requires contractors on public construction projects over $75,000 to pay each worker at least the hourly rate set for that worker’s trade and county in the state’s Annual Wage Order, counting both cash wages and fringe benefits. The rules sit in Sections 290.210 through 290.340 of the Revised Statutes, with the compliance mechanics in 8 CSR 30-3. Underpayment carries daily fines, exposes the contractor to a worker lawsuit for double the shortfall, and can lead to debarment from public work.
When the Law Applies
The prevailing wage obligation starts when either the engineer’s estimate or the accepted bid for a project exceeds $75,000, measured across the entire project scope rather than any single contractor’s share.1Missouri Revisor of Statutes. Missouri Code 290.230 – Prevailing Wage Rates Required on Construction of Public Works A public body cannot slice a project into smaller contracts to stay under the threshold. If a change order pushes a sub-threshold project over $75,000 mid-stream, prevailing wage applies only to the portion of work above that line.
Covered work includes construction, reconstruction, enlargement, alteration, painting, decorating, and major repair of fixed works built for public use or paid for with public funds. Routine maintenance is excluded.1Missouri Revisor of Statutes. Missouri Code 290.230 – Prevailing Wage Rates Required on Construction of Public Works Replacing a full roof will usually qualify as construction; patching a small section may be maintenance. The classification often decides whether the wage obligation attaches at all.
A “public body” is the state of Missouri or any officer, board, commission, political subdivision, or institution supported in whole or in part by public funds.2Missouri Revisor of Statutes. Missouri Code 290.210 – Definitions School districts, counties, state universities, and municipal authorities all qualify. If taxpayer dollars pay for the construction and the contract clears the threshold, assume the law applies.
How the Required Rate Is Set
The Missouri Department of Labor and Industrial Relations issues a final Annual Wage Order by July 1 each year. It lists the prevailing hourly rate for every occupational title in every county, drawn from actual wages paid in that county’s construction market.3Missouri Department of Labor and Industrial Relations. Missouri Prevailing Wage Law and Resources The applicable schedule is attached to the project specifications so every bidder prices the job against the same wage floor.4Missouri Revisor of Statutes. Missouri Code 290.250 – Determination of Prevailing Rates of Wages You can look up the current order for any county through the department’s online tool.5Missouri Department of Labor and Industrial Relations. Annual Wage Order Look-Up
Each rate has two parts: a basic hourly cash wage and a fringe benefit rate. Added together, they are the total prevailing hourly rate the contractor must meet.
What Counts as Fringe
Fringe includes the employer’s voluntary contributions to health insurance, pension and retirement plans, life and disability insurance, vacation and holiday pay, apprenticeship training funds, and similar legitimate benefit programs.6Missouri Revisor of Statutes. Missouri Code 290.210 – Definitions Payments already required by other law — Social Security taxes, workers’ compensation premiums — do not count toward the fringe obligation.
Contractors have flexibility in how they hit the total. They can provide actual benefits, pay the whole amount in cash, or combine the two, so long as the sum reaches the prevailing rate for that trade and county.6Missouri Revisor of Statutes. Missouri Code 290.210 – Definitions If the benefit package falls short of the listed fringe rate, the difference must be paid to the worker in cash. Most underpayment problems hide here: the base wage looks right, but the fringe doesn’t add up.
Apprentices on Public Works
Registered apprentices can be paid a reduced rate, but Section 290.235 caps the ratio at one apprentice per journeyman, per contractor, per trade on a given project. Any excess apprentices must be paid at the full journeyman rate.7Missouri Department of Transportation. 110.3 Prevailing Wages and Records (Guidance for Sec 110.3)
The contractor must keep written proof of each apprentice’s enrollment in a registered program, including the apprentice’s name, the program they belong to, and the percentage of prevailing wage they are entitled to receive. Without that documentation, the worker has to be classified and paid as a journeyman.
Posting, Records, and Certified Payroll
Before work begins, pull the Annual Wage Order for the project’s county and trades, and post physical copies of the applicable rates at the job site where workers can see them. That posting is what lets every worker check pay against the required rate.
Payroll is kept on Form LS-57, the Contractor’s Payroll Records form issued by the Department of Labor.8Missouri Department of Labor and Industrial Relations. Missouri Department of Labor Contractors Payroll Form (LS-57) For each worker it captures name and address, occupational title and classification (journeyman, entry-level, or registered apprentice), hourly rate, daily and weekly hours, deductions, and actual wages paid.9Missouri Secretary of State. 8 CSR 30-3.010 – Prevailing Wage Certified copies go to the public body overseeing the project every month, and the records must be available at all times for inspection by the Department of Labor.
At the end of the job, Section 290.290 requires the contractor to file a sworn affidavit of compliance confirming that every worker was paid at or above the prevailing rate throughout the project. Final payment is not released until that affidavit is filed.
Penalties and Worker Remedies
Enforcement runs through several tracks at once: administrative fines, withheld payments, private lawsuits, and debarment.
Daily Fines
A contractor can be fined $100 per day for each worker paid below the required rate. The Department of Labor must investigate the complaint, notify the employer of its findings, and issue a formal notice of penalty before the fine becomes due. The contractor then has 45 days from that notice before the penalty is payable.4Missouri Revisor of Statutes. Missouri Code 290.250 – Determination of Prevailing Rates of Wages
Withheld Payments
The public body awarding the contract has its own duty. When it finds violations, it must withhold from contractor payments all sums owed as a result of the underpayment, and report the violation to the Division of Labor Standards.9Missouri Secretary of State. 8 CSR 30-3.010 – Prevailing Wage
Worker Lawsuits for Double Damages
Any worker paid less than the prevailing rate can sue for double the difference between what they received and what the contract required, plus reasonable attorney fees as determined by the court. The statute treats the claim as a suit for wages, giving the judgment the same priority and enforcement power as other wage judgments.10Associated Builders and Contractors. Missouri Revised Statutes – Section 290.300 A worker does not have to wait for the Department of Labor to act before filing.
Debarment
Contractors prosecuted and convicted of violating the prevailing wage law are placed on a debarment list maintained by the Department of Labor.11Missouri Department of Labor and Industrial Relations. Contractor Debarment List Debarment blocks the firm from bidding on any public works project in the state for the length of the penalty.
Filing a Complaint as a Worker
Workers who believe they are being paid under the prevailing rate file through the Division of Labor Standards using Form PW-6.12Missouri Department of Labor and Industrial Relations. Prevailing Wage Complaint Form (PW-6) The department investigates and determines whether a violation occurred. Keep your own records of hours worked, pay received, and the project name; that documentation strengthens both the complaint and any lawsuit you decide to file.
