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 Petroleum County without local notice.
This schedule mixes sources: 64% of lines carry union identifiers and the rest are survey-based. Two crews on one site can be governed by rates that update on entirely different rhythms.
A wage determination is cited as number plus modification, for example MT20260077 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.
Synced from SAM.gov July 18, 2026. The wage determination incorporated into your contract is the legally operative document.
