The Iowa Department of Transportation (Iowa DOT) is seeking bids for a roofing replacement project at the Maquoketa Maintenance Garage through a Request for Bid (RFB) numbered 645-RFB-2156-2026. The project involves comprehensive roof renovation, specifically removing the existing EPDM roof membrane, ballast, and insulation, and replacing it with a new ballasted EPDM membrane complete with new insulation and vapor barrier. Bid solicitation opened on October 2, 2025, with a closing date of October 23, 2025, at 1:00 PM CDT. Pre-bid site visits are strongly recommended and scheduled for October 8, 2025 (8:00-10:00 am CT) and October 9, 2025 (1:00-3:00 pm CT). The project is anticipated to commence after award and must be completed by May 30, 2026. Award will be determined by the most advantageous bidder, with evaluation criteria including cost, compliance with mandatory requirements, proposed staffing, and work schedule. The contract will facilitate monthly payments covering 97% of performed work value, including acceptable materials stored on-site.

Bidders must be registered with the Iowa Division of Labor in the Department of Workforce Development and may be required to provide a performance and payment bond if the contract exceeds $25,000. The procurement will be conducted through the Iowa Management of Procurement and Contracts System (IMPACS), with all communications directed to a specific purchasing agent. As a tax-exempt agency, the Iowa DOT has specific administrative requirements for contractors. While no specific set-aside designations were mentioned, potential bidders should note that Davis-Bacon wages do not apply to this project. The procurement appears open to qualified contractors capable of executing the technical specifications of the roof replacement. Although a specific budget range was not disclosed, the comprehensive nature of the roofing replacement suggests a substantial project investment, likely in the tens to hundreds of thousands of dollars depending on the garage's specific dimensions and complexity of the roofing system.
