The Minnesota Department of Labor and Industry (DLI) conducts an annual voluntary survey of contractors in construction to determine state prevailing-wage rates for commercial, highway/heavy and residential construction projects in Minnesota.

How to participate

Important survey dates

  • The notification period for the 2024 prevailing-wage survey was open from April 1, 2024, to May 31, 2024. The survey notification period is now closed.

  • Surveys can be submitted for the 2025 prevailing-wage survey.

Survey tips (surveys can be submitted throughout the year)

  • Workers can be reported more than once, but only once for each project.

  • Workers reported on a survey must have worked at least eight hours on the project.

  • Where a worker performs work in more than one class of labor on a project, the worker shall be placed in the class in which the person worked the greatest number of hours.

  • Highway/heavy project data may only be reported if the cost of the project is $25,000 or more.

  • Commercial or residential project data may only be reported if the total cost of each project is $2,500 or more. Commercial construction includes apartment complexes and residential structures of three units or more. Residential construction applies to single-family and two-family homes.

  • Review classification titles to ensure correct reporting. For equipment operators, use the classification code under the highway/heavy list 302-397 or under the commercial or residential list 501-550; for paving and grading equipment for all types of construction, use the highway/heavy list 302-397. The classification list is available from the Office of the Revisor of Statutes website at 5200.1100, Minnesota Administrative Rules.
