Independence Mental Health Institute Infirmary Building Roof Replacement

The Iowa Department of Administrative Services is seeking bids to replace the roof of the Infirmary building at the Independence Mental Health Institute. The work includes full removal of the existing asphalt‑shingle and EPDM flat‑roof systems, remediation of identified asbestos‑containing materials, installation of new roofing membranes, flashing, and related waterproofing, as well as associated demolition, rough carpentry, and metal‑work. The contract is a firm‑price construction solicitation with a 5 % bid‑bond requirement and a sealed‑until bid deadline. The project is exempt from Iowa sales tax and Davis‑Bacon wage rules, and the State encourages targeted small‑business participation. • Remove existing roof shingles, EPDM membrane, and associated underlayment; inspect and replace damaged roof sheathing (30 × 4 ft × 8 ft plywood sheets provided as an allowance). • Perform required asbestos abatement for identified ACM prior to demolition, using a licensed asbestos contractor. • Install new self‑adhered underlayment, Class A asphalt shingles, EPDM membrane on flat‑roof sections, and all required metal flashings, drip‑edge, scuppers, and roof‑edge metal. • Provide required bid security (5 % of bid), performance/payment bonds, and comply with Iowa non‑discrimination and TSBE subcontractor requirements.
