A wage determination is cited as number plus modification, for example CO20260004 Mod dated May 18, 2026. Your certified payroll should reflect the determination in your contract, not necessarily the newest one.
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.
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.
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.
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.
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.
