Prevailing Wage Guide on Public Works Contracts


The Montana Prevailing Wage Law requires the prevailing wage rates established by the Montana Department of Labor & Industry be paid on public works contracts. The intent of the law is to:

  • protect local labor markets,
  • maintain the general welfare of Montana workers on public works projects,
  • eliminate wage cutting as a method of competing for public contracts,
  • maintain wages and rates paid on public works at a level to attract highly skilled laborers performing quality workmanship, and
  • prevent the rate of wages from adversely affecting the equal opportunity of Montana contractors to bid on public works.
