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) | $60.65 |
| Health and welfare | $16.82 |
| Pension | $18.36 |
| Training | $1.65 |
| Other benefits | $2.04 |
| Total straight-time hourly rate | $99.52 |
Set from: collective bargaining agreement, Commercial/Industrial-Master Labor Agreement and Working Rules of the United Association Local 290. 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).
Davis-Bacon plumber or pipefitter rate in Clark 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.

When this rate changes
- 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 February 3, 2025 and took effect March 5, 2025.
