This schedule has been stable recently; the last modification is dated May 18, 2026. Stability is not permanence: annual editions and mid-year modifications can reset rates in Union County without local notice.
89% of the rate lines here carry union local identifiers, so the published figures track negotiated agreements, which is why some classifications carry high fringe amounts relative to base.
A wage determination is cited as number plus modification, for example OR20260090 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.
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.
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.
