L&I published this rate on August 1, 2025 and it took effect August 31, 2025. L&I hasn't changed it since, so it is still current in period 2026-2. Checked against L&I's wage lookup on October 24, 2026.

Base wage and fringe benefits: $62.02 + $25.77

The wage is the taxable hourly rate. The other lines are what Washington law calls "usual benefits": contributions to health, pension, vacation and holiday, apprenticeship and similar plans. A contractor that doesn't provide a benefit pays its value as wages instead (RCW 39.12.010).

Base wage (taxable)	$62.02
Health and welfare	$15.54
Pension	$7.92
Training	$1.20
Other benefits	$1.11
Total straight-time hourly rate	$87.79

Set from: collective bargaining agreement, Master Agreement 2022-2026 Western Insulation Contractors Assoc. of Oregon & Washington Inc. Portland, Oregon & International Association of Heat & Frost Insulators & Allied Workers Local Union No. 36 Portland, Oregon. Where a county has a collective bargaining agreement, L&I adopts its wage and benefits; with more than one, the higher rate prevails. Otherwise L&I uses wage surveys (RCW 39.12.015).

Overtime

L&I overtime code 1F:

Overtime Calculations are based on the hourly rate actually paid to the worker. On public works projects, the hourly rate must be not less than the prevailing rate of wage minus the hourly rate of the cost of fringe benefits actually provided for the worker.

ALL HOURS WORKED IN EXCESS OF EIGHT (8) HOURS PER DAY OR FORTY (40) HOURS PER WEEK SHALL BE PAID AT ONE AND ONE-HALF TIMES THE HOURLY RATE OF WAGE.

The first two (2) hours after eight (8) regular hours Monday through Friday and the first ten (10) hours on Saturday shall be paid at one and one-half times the hourly rate of wage. All other overtime hours worked, except Labor day, shall be paid at double the hourly rate of wage. All hours worked on Labor day shall be paid at three times the hourly rate of wage.

Washington has no single overtime rule for prevailing wage. Each rate carries its own L&I code, copied here as published.

When does this rate change?

Rates lock at the bid date. A project uses “the rates that are in effect on the date when bids by prime contractors are due”, and they stay for the life of the contract. If the contract isn't awarded within six months of the bid date, the award-date rates apply. Contracts without bids use the date they're signed (WAC 296-127-011).
L&I publishes on the first business day of February and August, and rates take effect 30 days later. Corrections can be published at any time and also take effect 30 days later (WAC 296-127-011(1); L&I publications and corrections). L&I's next set is due February 1, 2027, effective March 3, 2027.
L&I doesn't republish every rate each period. A rate stays until L&I changes it, so each one has its own date. This one was published August 1, 2025 and took effect August 31, 2025.
