How often do these rates change?

DOL publishes wage determination modifications weekly, generally on Fridays. The determination behind this page was last modified June 16, 2026.

What is the difference between the base rate and the fringe rate?

The base rate is the minimum hourly wage; the fringe amount is an additional hourly benefit obligation you can meet with bona fide benefit contributions or pay in cash. On this schedule the median fringe is about 44% of base.

My classification is not listed for Mason County. What do I do?

What counts as highway construction?

Highway covers roads, streets, runways, and similar paving work not incidental to building, residential, or heavy construction.

Does the federal rate or the Washington state prevailing wage apply?

They are separate systems. Davis-Bacon rates apply to federally funded or assisted work; a state prevailing wage law can apply to state-funded work. A project can be covered by both, in which case the higher rate for each classification effectively controls. This page shows the federal determination only.

Is the WH-347 form mandatory?

The WH-347 itself is optional; what is mandatory on covered work is submitting weekly certified payroll with the same information and a signed Statement of Compliance. Most contractors use the WH-347 layout because agencies expect it.

Using these rates

Read the modification number

A wage determination is cited as number plus modification, for example WA20260001 Mod dated June 16, 2026. Your certified payroll should reflect the determination in your contract, not necessarily the newest one.

Put the WD in your bid file

Save the full determination text with your bid papers the day you price the job. If rates change later, the contract determination is your record of what you bid against.

Match classifications by duties, not titles

The classification that applies is determined by the work performed, not the worker's title. A foreman who works with the tools is generally due the rate for the hours on the tools.

Fringe crediting basics

You can meet the fringe obligation with bona fide benefit plan contributions, cash, or a combination. Track the hourly equivalent of what you contribute; agencies ask for the math.

Statement of Compliance wording

The signed Statement of Compliance may be the WH-347 back page or another document with identical wording. The signature is a federal certification by your company's officer; accuracy is on the certifier.

Use last-4 SSN only

Certified payroll uses the employee's name and an individually identifying number, normally the last four digits of the Social Security number. Full SSNs do not belong on submitted payrolls.
