Michigan Davis-Bacon wage determination changes, 2026
The U.S. Department of Labor published 166 modifications to 157 of Michigan's Davis-Bacon wage determinations between May 18, 2026 and August 13, 2026 that changed, added or removed a rate. Across them, 22 rates went up, 0 went down, 6,157 rows were added and 203 removed.
From every revision of each WD on SAM.gov, compared row by row (rate identifier and classification) and read twice. 157 of these modifications are dated May 18, 2026, when DOL reissued most WDs. Totals are base plus fringe. A contract keeps the modification in its bid documents, so a later one only reaches new bids. Michigan prevailing wage rates by county

Questions about Michigan's Davis-Bacon changes
How often do Davis-Bacon wage rates change in Michigan?
Whenever DOL modifies a wage determination. Between May 18, 2026 and August 13, 2026, DOL published 166 modifications to 157 Michigan wage determinations that changed, added or removed a rate; 157 of them are dated May 18, 2026, when DOL reissued most WDs.
Which Michigan Davis-Bacon rate changed the most in 2026?
ELECTRICIAN: ALARM INSTALLATION & LOW VOLTAGE WIRING (TOWNSHIPS OF ALAIEDON, AURELIUS, DELHI, INGHAM, LANSING, LEROY, LO (electrician) on MI20260084: $40.90 to $60.02 an hour in modification 2, published July 20, 2026, for building construction.
Does a new modification change the rates on my contract?
A contract keeps the wage determination in its bid documents. Modifications published before bid opening apply to it, though one published less than 10 days before can be left out if the agency finds there isn't time to tell bidders (29 CFR 1.6(c)).
Where are the official Michigan wage determinations?
On SAM.gov. Each row on this page links the new revision there and the one it replaced, and every Michigan rate page names its WD and modification.
