Base wage and fringe benefits: $53.80 + $17.83

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)	$53.80
Health and welfare	$9.25
Pension	$7.76
Training	$0.77
Other benefits	$0.05
Total straight-time hourly rate	$71.63

Set from: collective bargaining agreement, Eastern Washington Northern Idaho Area Master Agreement between The Inland Northwest AGC (A Chapter of the Associated General Contractors of America, Inc.) and The Pacific Northwest Regional Council of Carpenters. Carpenters-Millwrights-Piledrivers. 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 4X:

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.

All hours worked on Saturdays shall be paid at one and one-half times the hourly rate of wage. All hours worked on Sundays and holidays shall be paid at double the hourly rate of wage. Work performed outside the normal shift of 6 am to 6pm shall be paid at one and one-half the straight time rate, (except for special shifts or three shift operations). All work performed on Sundays and holidays shall be paid at double the hourly rate of wage. Shifts may be established when considered necessary by the Employer.

The Employer may establish shifts consisting of eight (8) or ten (10) hours of work (subject to WAC 296-127-022), that shall constitute a normal forty (40) hour work week. The Employer can change from a 5-eight to a 4-ten hour schedule or back to the other. All hours of work on these shifts shall be paid for at the straight time hourly rate. Work performed in excess of eight hours (or ten hours per day (subject to WAC 296-127-022) shall be paid at one and one-half the straight time rate.

When due to conditions beyond the control of the Employer, or when contract specifications require that work can only be performed outside the regular day shift, then by mutual agreement a special shift may be worked at the straight time rate, eight (8) hours work for eight (8) hours pay. The starting time shall be arranged to fit such conditions of work.

When an employee returns to work without at a break of eight (8) hours since their previous shift, all such time shall be a continuation of shift and paid at the applicable overtime rate until such time as the employee has had a break of eight (8) hours.

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 3, 2026 and took effect September 2, 2026.

Davis-Bacon pile driver rate in Benton County

Federally funded or assisted construction here uses the U.S. Department of Labor's wage determinations. When a contract requires both the state rate and the Davis-Bacon rate, paying the higher of the two meets both. The contract documents say which apply.

We don't put a federal figure next to L&I's here, because the two schedules' classifications don't line up one to one. The federal rows for this trade are below; match the classification to the work.
