On Oregon public works in each of these 36 counties, an insulator must be paid at least $90.94 an hour: a $64.37 base wage plus $26.57 in fringe. BOLI prints no total, so $90.94 is our sum of the two.
BOLI book of September 3, 2026 with the October 5, 2026 amendment; this rate, effective September 3, 2026. A project generally uses the rates in effect when its bid specifications were first advertised, for the whole project (OAR 839-025-0020). Checked against oregon.gov on October 25, 2026.
Base wage and fringe benefits: $64.37 + $26.57
The base wage is the taxable hourly wage. BOLI prints the fringe 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.
| Base wage (taxable) | $64.37 |
| Fringe benefits (one figure, not itemized) | $26.57 |
| Base + fringe (our sum; BOLI prints no total) | $90.94 |
When does this rate change?
- A project uses the rates in effect when its bid specifications were first advertised, and a later book or amendment doesn't change it (OAR 839-025-0020(6)).
- BOLI updates rates about quarterly, by book or amendment. This page uses the September 3, 2026 book with the October 5, 2026 amendment, for projects first advertised from October 5, 2026 (BOLI rates).
Davis-Bacon insulator rates in these counties
The counties share BOLI's rates, but not always the same federal wage determination. On projects that are also federal, Oregon requires the higher of the state and the federal rate, and the specifications must contain both (ORS 279C.830, 279C.838).
