The most recent modification to the governing determination is dated June 25, 2026. DOL's weekly publication cycle means further modifications can post on any Friday.
Most rate lines here carry SU or state-adopted identifiers, meaning they come from wage surveys rather than negotiated agreements. Survey rates change less often but can jump when a new survey publishes.
Using these rates
Read the modification number
A wage determination is cited as number plus modification, for example IA20260028 Mod dated June 25, 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.
Check rates the Friday before payroll
DOL publishes modifications weekly, generally Fridays. A quick check before running payroll catches a mid-project modification before it shows up in an agency review instead.
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.

* changed in the most recent modification. Survey-based (SU) identifiers are non-union survey rates. Amounts tagged per day or per shift are published that way in the source determination and are not hourly wages; they are excluded from the hourly figures above.
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.
