Prevailing Wage Requirements in Missouri: Government Contract Rules

The Davis-Bacon Act, codified at 40 U.S.C. § 3141 et seq., requires contractors and subcontractors on federally funded construction projects to pay workers not less than the prevailing wage as determined by the U.S. Department of Labor (DOL). The Act covers projects receiving federal assistance over $2,000, including highways, buildings, and public works. Covered employers must pay all workers on the project the prevailing wage rate for their trade in the project location, regardless of the worker's union status or individual employment agreement.

Prevailing wage under federal law includes both the base hourly rate and fringe benefits (health insurance, pension contributions, paid leave). The DOL publishes prevailing wage rates by state, county, and occupational classification. Employers must maintain detailed payroll records and post wage notices on job sites. Violations can result in wage deductions, withheld payments, debarment from federal contracts, and civil liability. The DOL's Wage and Hour Division enforces Davis-Bacon requirements.

Federally funded projects include not only direct federal construction but also projects receiving federal grants, loans, loan guarantees, or other financial assistance. This includes work funded through transportation grants, HUD funding, and infrastructure programs. Employers have affirmative obligations to ensure all workers receive prevailing wages and may not require workers to rebate portions of prevailing wages.

Missouri Revised Statutes section 290.210 et seq. establishes the state prevailing wage law, which applies specifically to public works projects funded or paid for in whole or in part by the state of Missouri or any political subdivision (counties, cities, school districts, and other public entities). The Missouri Department of Labor and Industrial Relations (DOLIR) is responsible for determining and publishing prevailing wage rates for each county and occupational classification.

Unlike some states, Missouri's prevailing wage law is narrower in scope than federal law and covers only state and locally funded projects, not all construction. The state does not have an independent wage threshold requirement; instead, all public works projects receiving any public funding are covered. Contractors and subcontractors must pay at least the prevailing wage rate published by DOLIR for the county where work is performed. These rates include both base hourly wages and fringe benefits (health insurance, pension, vacation, holidays, and other benefits as specified in the rate schedule).

Missouri law covers all workers on public works projects, including apprentices and trainees, though apprentices may be paid a reduced rate if they are registered in an approved apprenticeship program. Unlike some states, Missouri does not require prevailing wage on all public employee wages or salaries; the requirement applies primarily to construction and related trades.

Remedies under Missouri law include wage deductions from payments due to the contractor, contract termination for non-compliance, debarment from future public projects, and civil penalties. Workers may pursue claims through the DOLIR or through private action. The state allows prevailing wage claims to be brought by workers, employee organizations, and the state itself. Penalties include unpaid wages with interest, liquidated damages, and attorney's fees in some cases.

Missouri prevailing wage law contains several important exceptions and limitations. The law does not apply to private construction projects, even if performed on public property or for public benefit; it applies only when the project is funded or paid for by the government. Projects funded entirely by private sources are exempt, even if they benefit the public or are located on public land.

Small projects may have reduced compliance burdens. While Missouri law does not establish a cost threshold below which prevailing wage does not apply, individual agencies may have purchasing thresholds that exempt very small maintenance or repair work. However, these exemptions are narrow and agency-specific.

Apprentices and learners may be paid less than the full prevailing wage if they are registered in an approved apprenticeship program recognized by the Department of Labor. The apprentice rate is typically 50-75% of the journeyperson prevailing wage rate. Employers must maintain apprenticeship documentation to claim this exception.

Federal prevailing wage law contains additional exceptions for small projects (under $2,000), certain utility work, and emergency repairs, but these do not reduce Missouri state law obligations. When both federal and state law apply, the higher prevailing wage rate controls. Workers employed in a supervisory capacity may not be entitled to prevailing wage if they are classified as bona fide supervisors, though this exception is strictly construed.

Missouri prevailing wage law does not apply to work performed by employees of the public entity itself on their own projects; however, many public entities contract out work, bringing the project within prevailing wage requirements. The law also does not apply to employees of suppliers or manufacturers providing materials to a public works project, only to workers actually performing work on the project site.

Step 1: Document all wages and hours. Keep detailed payroll records showing the date, hours worked, hourly rate paid, and fringe benefits provided for each worker. Retain invoices, timecards, and payment records. Take photographs or notes of work performed. Document the prevailing wage rate that was applicable (print the DOLIR rate schedule for your county and trade). If you believe prevailing wage was not paid, gather your own pay stubs, W-2 forms, and any communications from your employer about wages.

Step 2: File an internal complaint or demand. First, raise the issue directly with your employer or project manager in writing, requesting payment of any unpaid prevailing wage and asking for a detailed explanation of the wage calculation. Keep a copy of this communication. Many employers will correct underpayment voluntarily to avoid further action. Request a written response within 10 business days. Document the employer's response or refusal.

Step 3: File a complaint with the Missouri Department of Labor and Industrial Relations. Visit the DOLIR Prevailing Wage Division online at https://labor.mo.gov/dls/pwork or call (573) 751-2675. You can file a complaint online or by mail. Include your name, employer name, project name and location, dates of work, wages paid, and the applicable prevailing wage rate. Attach copies of payroll records, pay stubs, timecards, and your wage calculation showing the shortfall. There is no filing fee. You may also file a federal Davis-Bacon complaint with the U.S. Department of Labor Wage and Hour Division if the project was federally funded; visit https://www.dol.gov/agencies/whd/prevailing-wage.

Step 4: Understand the investigation process. The DOLIR will investigate your complaint by contacting the contractor and public entity funding the project. The investigation typically takes 30-60 days. The agency will review payroll records, prevailing wage rate schedules, and project documentation. You will be contacted for additional information if needed. The agency may conduct an on-site investigation or records audit. Once investigation is complete, the DOLIR will notify you of findings and any remedies ordered.

Step 5: Pursue legal remedies if necessary. If the DOLIR finds a violation, it may order the contractor to pay unpaid wages with interest and penalties. If the contractor refuses to comply, you may file a civil action in Missouri state court to recover unpaid wages. Consult an employment attorney licensed in Missouri if the amount owed is significant (over $1,000) or if the employer retaliated against you for filing a complaint. Many employment attorneys offer free initial consultations and may handle the case on a contingency basis (paid from recovered wages).
