On Montana public works in each of these 21 counties, a millwright must be paid at least $68.97 an hour: a $45.26 base wage plus $23.71 in benefits. DLI prints no total, so $68.97 is our sum of the two.

Davis-Bacon millwright rates in these counties
The counties share DLI's rates, but not always the same federal wage determination. Montana's law doesn't apply where federal law sets the rate, so a Davis-Bacon job uses the federal schedule (DLI FAQ).

When this rate changes
- Montana rates lock when the bid specifications are advertised, so a later revision doesn't change an advertised project (ARM 24.17.127; section E of each 2026 schedule). Contracts of more than 30 months add 3% a year (MCA 18-2-417).
- DLI sets rates once a year and revises them mid-year when needed. The 2026 rates were revised effective April 25, 2026; the 2027 drafts are out for comment until November 15, 2026 (DLI rates page).
