The base wage is the taxable hourly wage. DLI prints the benefits as one hourly figure, not itemized; it can go to health, pension, vacation and training plans, or be paid as cash where the state allows.

| Fringe benefits (one figure, not itemized) | $16.79 |
| Base + benefits (our sum; DLI prints no total) | $49.13 |
When does this rate change?
- 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).

Davis-Bacon operating engineer rate in Petroleum County
Federally funded or assisted construction here uses the U.S. Department of Labor's wage determinations. Montana's law doesn't apply where federal law sets the rate, so a Davis-Bacon job uses the federal schedule (DLI FAQ).
We don't put a federal figure next to DLI's here, because the federal determinations split this trade into groups that don't line up with DLI's. The federal rows for this trade are below; match the classification to the work.
