DOC Anamosa State Penitentiary SallyPort Tunnel & Living Unit B Tunnel Repair

The Iowa Department of Administrative Services is requesting bids for concrete repairs to the Sallyport and Living Unit B utility tunnel lid and wall structures at Anamosa State Penitentiary, Anamosa, Iowa, with bids due October 5, 2026 at 2:00 p.m. via IMPACS Electronic Procurement System. Attendance at a mandatory pre-bid meeting on September 21 or September 22, 2026 at 10:00 a.m. at the penitentiary is required to qualify for bidding.

The scope includes demolition and replacement of tunnel lids, repair of existing stone masonry walls, installation of 8-inch reinforced PCC paving with #5 bars at 18-inch spacing, and associated structural work. Concrete must achieve 4,000 PSI compressive strength at 28 days with a maximum water-cementitious materials ratio of 0.45; high early strength M-mix concrete is specified to minimize drive closures. All reinforcing steel must be epoxy-coated, and integral crystalline waterproofing admixtures are required. Special inspections must verify reinforcing steel placement, concrete compressive strength and slump testing, and anchoring of post-installed elements. Emergency vehicle access must be maintained throughout construction, and tunnels cannot remain open overnight—they must be capped daily with either new concrete lids or temporary steel plates. All work must comply with the 2024 International Building Code, Iowa Department of Transportation specifications, and SUDAS standards. Contractors are responsible for all temporary bracing, site safety, debris removal, and replacement of any pavement or structures damaged during construction at no additional cost.

The project is designated a small business opportunity. Construction is anticipated to begin October 23, 2026 and conclude November 12, 2026. Bid security of 5% of the total bid amount is required in the form of a bid bond, cashier's check, or certified check. Performance and payment bonds will be required from the successful bidder. Questions and product substitution requests are due by 2:00 p.m. on September 25, 2026. The contract will be awarded as a lump sum. The project is exempt from Iowa sales tax and Davis-Bacon wage requirements do not apply. Contact Michael Bradbury, Issuing Officer, at (515) 823-9327 or construction.procurement@das.iowa.gov.
