The Iowa Department of Transportation (Iowa DOT) has issued Request for Bid 645-RFB-2074-2026 for a specialized underground tile repair project located 1/4 mile west of the US-30/IA-25 interchange in Greene County. The procurement solicits a qualified contractor to repair an existing 18" concrete tile structure approximately 14 feet below grade, requiring comprehensive labor, materials, and equipment provisions. Key project deliverables include installing temporary traffic signals, executing a lane closure on the westbound US-30 lane, and performing full pavement restoration using either full-depth PCC or HMA. The bid is open from August 28, 2025, to September 25, 2025, with bid opening scheduled for September 25, 2025, at 1:00 PM CDT via Microsoft Teams. Evaluation criteria will include consideration of mandatory requirements, proposed staffing, time schedules, past work performance, and overall work capacity, with the Iowa DOT selecting the most advantageous bidder. Contractors must be registered with the Iowa Department of Workforce Development and provide appropriate lead times for materials. The project timeline is anticipated to span from October 1, 2025, to November 28, 2025.

No specific set-aside designations or restrictions for disadvantaged enterprises were explicitly mentioned in the documentation. The project will require contractors to maintain appropriate insurance coverage and be prepared to work around existing utilities, including overhead transmission poles and an underground fiber line in the north right-of-way. Bidders must independently locate and verify existing utility locations prior to commencing work. The contract will be funded through the Iowa DOT, with deliveries designated as F.O.B. Destination, and the procurement is tax-exempt with Davis-Bacon wages not applying to this project. While no specific budget range was provided, the comprehensive nature of the repair work suggests a moderate-scale infrastructure maintenance contract. The bid represents a targeted infrastructure improvement project focusing on precise underground tile system repair within a specific geographic location in Greene County.
