Missouri's Public Works Regulations

Missouri has both state and federal regulations governing prevailing wages for public works projects:

  • State Law: The Missouri Prevailing Wage Law (RSMo Chapter 290.210 to 290.340) requires contractors and subcontractors on state and local public works projects to pay workers at least the prevailing wage rates set by the Missouri Department of Labor and Industrial Relations (DOLIR), administered by the Division of Labor Standards (DLS). Rates are set per county and per occupational title through the annual wage survey process.
  • Federal Law: For federally funded or federally assisted projects, contractors must comply with the federal Davis-Bacon Act, which mandates payment of prevailing wages set by the U.S. Department of Labor.

Definition of "Public Works" in Missouri

In Missouri, public works refers to construction, reconstruction, improvement, enlargement, alteration, painting, or major repair work financed in whole or in part by public funds. Public works projects can include:

  • Roads, highways, and bridges
  • Public schools, government buildings, and other public infrastructure
  • Water and sewage systems
  • Airports, transit facilities, and other public infrastructure
  • Federally assisted energy projects, including solar, wind, broadband, and EV charging stations

Key point: The Missouri Prevailing Wage Law applies to public works projects costing more than $75,000, while the Davis-Bacon Act applies to federal or federally assisted construction contracts of $2,000 or more.

Missouri Prevailing Wage Determinations: State and Federal Requirements

Missouri Prevailing Wage Law

  • The Division of Labor Standards (DLS), within DOLIR, sets Missouri's prevailing wage rates by county and by occupational title (HB 1729 consolidated occupational categories down to 20).
  • Draft rates are filed with the Missouri Secretary of State by March 10, and the final Annual Wage Order is published by July 1 each year.
  • Public bodies must request the applicable Annual Wage Order at least 10 calendar days before advertising the bid (8 CSR 30-3.010).

Federal Davis-Bacon Act (DBA)

  • Applies to federal or federally assisted construction contracts of $2,000 or more.
  • Contractors must pay no less than the locally prevailing wages and fringe benefits as determined by the U.S. Department of Labor, published on SAM.gov.

Components of Wage Determinations

Both state and federal wage determinations in Missouri include:

  • Basic Hourly Rate: The minimum wage rate paid directly to workers for every hour worked.
  • Fringe Benefits: Health insurance, retirement, paid leave, or other benefits paid on top of the basic rate.
  • Total Hourly Rate: The sum of the basic hourly rate and fringe benefits.

If no fringe benefits are provided, the contractor must pay the full total hourly rate as cash directly to the worker.

Compliance for Contractors and Subcontractors

For both state-funded and federally funded public works projects in Missouri, contractors and subcontractors must adhere to the following compliance guidelines:

Determine Applicable Wage Rates

Determine Applicable Wage Rates

For federal projects, pull the applicable wage determination from SAM.gov. For state projects, use the Annual Wage Order issued by the Missouri Division of Labor Standards.

Submit Certified Payroll Reports

Submit Certified Payroll Reports

For federal projects, submit Form WH-347 weekly to the contracting agency. For Missouri public works projects, submit certified copies of payrolls monthly to the contracting public body (8 CSR 30-3.010), and file a signed Affidavit of Compliance with the public body at project completion before final payment is released (RSMo 290.290).

Handle Fringe Benefits

Handle Fringe Benefits

Pay every worker the correct prevailing wage for their occupational title, including basic hourly rate plus fringe benefits. If no fringe benefits are provided, pay the equivalent value as additional cash on top of the basic rate.

Maintain Accurate Records

Maintain Accurate Records

Keep payroll records, classifications, hours, wages, and fringe benefits for at least one year following project completion under Missouri law (RSMo 290.290). Federal Davis-Bacon recordkeeping runs for three years and includes worker contact information on DOL request. Records must be available for inspection by the Missouri Division of Labor Standards, the contracting public body, or the U.S. Department of Labor.

Penalties for Non-Compliance

Failure to comply with prevailing wage laws in Missouri can result in:

  • Back Wages owed to underpaid workers

  • Civil Fines assessed by the Division of Labor Standards

  • Criminal Prosecution for falsification of wage submissions

  • A worker's Right of Action for double the difference between wages paid and the prevailing rate, plus reasonable attorney's fees 

  • Debarment from bidding on future public works contracts for repeated or willful violations

  • Withholding of Payment until a satisfactory Affidavit of Compliance is filed

Unique Aspects of Missouri's Prevailing Wage System

Unique Aspects of Missouri's Prevailing Wage System

  • Local Wage Determination: Missouri's system determines prevailing wages based on surveys within each county rather than applying a single statewide rate. This means wage rates can vary significantly depending on the local market rates in each county.
  • Public Works Threshold: In Missouri, the prevailing wage requirement only applies to public works projects that exceed a specific threshold value. Projects below this threshold are exempt, allowing smaller projects to be completed without meeting prevailing wage requirements.
  • Annual Wage Order Cycle: Draft rates are filed with the Secretary of State by March 10, and the final Annual Wage Order is published by July 1 each year, with a 30-day objection window after filing with the Secretary of State.
  • Monthly Certified Payroll to the Public Body: Contractors file monthly with the awarding public body under 8 CSR 30-3.010, plus a final Affidavit of Compliance before final payment under RSMo 290.290.

Missouri Prevailing Wage FAQs

Does Missouri have a state-specific prevailing wage law?

Yes. The Missouri Prevailing Wage Law requires contractors on state and local public works projects costing more than $75,000 to pay workers the prevailing wage rates set by the Missouri Division of Labor Standards within DOLIR. For federally funded projects, the Davis-Bacon Act applies separately at a $2,000 threshold.

How are prevailing wage rates determined in Missouri?

For state-funded projects, the Missouri Division of Labor Standards sets prevailing wage rates by county and by occupational title through annual wage surveys. Draft rates are filed with the Secretary of State by March 10, and the final Annual Wage Order is published by July 1 each year. For federally funded projects, the U.S. Department of Labor sets rates published on SAM.gov, and contractors apply the determination in effect ten days before bid opening.

What are the penalties for non-compliance with prevailing wage laws in Missouri?

Penalties include back wages, civil fines from the Division of Labor Standards, a worker's right of action for double the difference between wages paid and the prevailing rate plus reasonable attorney's fees (RSMo 290.300), withholding of final payment until a satisfactory Affidavit of Compliance is filed, and debarment from future public works contracts for repeated or willful violations. Federal Davis-Bacon penalties layer on top when federal funds are involved.

How are fringe benefits handled under prevailing wage laws in Missouri?

Contractors must provide bona fide fringe benefits such as health insurance, retirement, or paid leave, or pay the equivalent value as additional cash on top of the basic hourly rate. Total compensation must equal at least the basic rate plus the fringe rate listed on the applicable Annual Wage Order or SAM.gov determination. If no fringe benefits are provided, the full total hourly rate must be paid as cash directly to the worker.
