Illinois Davis-Bacon wage determination changes, 2026
The U.S. Department of Labor published 77 modifications to 70 of Illinois's Davis-Bacon wage determinations between May 18, 2026 and October 22, 2026 that changed, added or removed a rate. Across them, 9 rates went up, 0 went down, 2,696 rows were added and 162 removed.
From every revision of each WD on SAM.gov, compared row by row (rate identifier and classification) and read twice. 70 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. Illinois prevailing wage rates by county

Questions about Illinois's Davis-Bacon changes
How often do Davis-Bacon wage rates change in Illinois?
Whenever DOL modifies a wage determination. Between May 18, 2026 and October 22, 2026, DOL published 77 modifications to 70 Illinois wage determinations that changed, added or removed a rate; 70 of them are dated May 18, 2026, when DOL reissued most WDs.
Which Illinois Davis-Bacon rate changed the most in 2026?
CEMENT MASON/CONCRETE FINISHER (HENDERSON (NORTHERN HALF), MERCER (EXCEPT SOUTHEASTERN PART), ROCK ISLAND, AND WHITESIDE (cement mason) on IL20260001: $51.64 to $62.64 an hour in modification 6, published October 22, 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 Illinois wage determinations?
On SAM.gov. Each row on this page links the new revision there and the one it replaced, and every Illinois rate page names its WD and modification.
