Radiant Heat System Replacement at the Williamsburg Garage

The Iowa Department of Transportation (Iowa DOT) is seeking qualified contractors for a Radiant Heat System Replacement project at the Williamsburg Maintenance Garage through a Request for Bid (RFB) numbered 645-RFB-2028-2026. The procurement involves a complete replacement of the existing ceiling-hung radiant heat system, with the selected contractor responsible for providing all necessary materials, labor, and equipment. Bid submissions will open on August 8, 2025, and close on August 29, 2025, at 1:00 PM CDT, with an anticipated contract completion date of November 25, 2025. Interested bidders are encouraged to schedule optional site visits by contacting Julie Brown and must submit various certifications and documentation as part of the bidding process. The evaluation criteria will consider multiple factors including cost, mandatory requirements, proposed staffing, time schedule, past work performance, and overall work capacity. Bidders must comply with Iowa Administrative Code 761-20 and be prepared to potentially provide performance and payment bonding if the contract value exceeds $25,000.

The procurement does not explicitly specify set-aside designations or restrictions for disadvantaged enterprises. Contractors will be required to maintain appropriate insurance coverage and comply with labor relations registration requirements. Payment terms are structured with a 0% rate and a net 60-day period, with the Iowa DOT making monthly payments covering 97% of the completed work value. The project falls under HVAC-related commodity codes specifically for heating systems, and the Iowa DOT is a tax-exempt agency. While no incumbent vendors are mentioned in the documentation, the bid is structured to be awarded to the most advantageous bidder. The procurement will be conducted via a virtual Microsoft Teams meeting, and interested parties should carefully review all documentation to ensure compliance with the detailed bidding requirements. Although a specific budget range is not explicitly stated, the comprehensive nature of the radiant heat system replacement suggests a significant capital investment for the infrastructure upgrade.
