VSSB252001 Repair Roof Building 235 Drawing Set Summary

This is a technical drawing set for the Iowa Department of Public Defense's roof replacement project at Building 235 of the 185th Air Refueling Wing located at Sioux Gateway Airport in Sioux City, Iowa. The project encompasses roof replacement across three roof areas (A, B, and C) totaling approximately 12,163 square feet. The scope of work requires contractors to remove the existing 60 mil EPDM roofing membrane, flashing, and two layers of 2-inch rigid insulation board, then install two layers of 2.6-inch rigid insulation (R-30) and a new 90 mil EPDM roofing membrane system. Additional work includes removal of specified equipment with utility disconnection and capping, installation of new flashing for all roof penetrations, installation of new gutter systems with concrete splash pads matching existing specifications, and installation of roof walk pads. The mandatory site visit is scheduled for June 3, 2026, at 10:00 AM, and all bids must be submitted by June 17, 2026, via the IMPACS site. A bidders' conference will be held to address questions and clarify requirements prior to the submission deadline. Contractors must field verify all quantities and measurements prior to bidding and comply with all applicable state and federal codes, standards, and regulations.

The project requires contractors to protect all existing roof equipment and facility property during construction, with any damage to be repaired at the contractor's expense. Contractors must also return the removed Elektror L138 siren to the contracting entity once disconnected and relocated from the roof. The contract will be competitively awarded based on technical qualifications, cost competitiveness, and demonstrated experience with similar commercial roofing projects, with pricing submitted as part of the proposal. The project is subject to prevailing wage requirements applicable to state projects, and funding is sourced through the Department of Public Defense's capital improvement budget. The contract term and completion timeframe will be established upon award and notice to proceed. The project may be set aside for small businesses or disadvantaged business enterprises in accordance with Iowa procurement regulations. The issuing officer is Philip Payton, reachable at 515-975-6211 or philip.payton@dpd.iowa.gov.
