Iowa Davis-Bacon wage determination changes, 2026
The U.S. Department of Labor published 83 modifications to 80 of Iowa's Davis-Bacon wage determinations between May 18, 2026 and June 25, 2026 that changed, added or removed a rate. Across them, 0 rates went up, 0 went down, 2,107 rows were added and 136 removed.
From every revision of each WD on SAM.gov, compared row by row (rate identifier and classification) and read twice. 80 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. Iowa Davis-Bacon rates by county

Questions about Iowa's Davis-Bacon changes
How often do Davis-Bacon wage rates change in Iowa?
Whenever DOL modifies a wage determination. Between May 18, 2026 and June 25, 2026, DOL published 83 modifications to 80 Iowa wage determinations that changed, added or removed a rate; 80 of them are dated May 18, 2026, when DOL reissued most WDs.
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 Iowa wage determinations?
On SAM.gov. Each row on this page links the new revision there and the one it replaced, and every Iowa rate page names its WD and modification.
