This is a Davis-Bacon Act Wage Determination document (WD #IA20260028, Modification 4) issued by the U.S. Department of Labor for heavy and highway construction projects in Iowa. The determination applies to 99 Iowa counties and establishes prevailing wage rates effective June 25, 2026.

The wage determination specifies hourly rates for multiple trade classifications organized by five geographic zones within Iowa. Trade classifications include bricklayers/stone masons, carpenters and piledrivermen, concrete finishers, electricians, ironworkers, laborers (Groups A, AA, B, and C), power equipment operators (Groups A, B, C, and D), and truck drivers. Rates vary by zone and classification type, with union rates identified by four-letter prefixes (SU, UAVG, SA, SC) indicating union-negotiated rates, weighted union averages, survey rates, or state-adopted rates. The document notes that wage rates are updated to reflect current collective bargaining agreements and remain in effect until superseded. Executive Orders 13706 and 13658 requirements regarding paid sick leave and minimum wage rates are referenced. Unlisted classifications may be added by the contracting officer per 29 CFR 5.5(a)(1)(iii). The wage determination appeals process is detailed, with initial inquiries directed to the Branch of Wage Surveys and appeals of adverse decisions to the Wage and Hour Administrator and Administrative Review Board.
