About this file
This document is an Addendum to a Request for Bids (RFB) for the DOC MPCF IPI Roof Replacement project issued by the Iowa Department of Administrative Services. The project entails roof recovering over an existing metal roof with roof overlay purlins and installing a new standing seam metal roof on the IPI warehouse building at the Mt. Pleasant Correctional Facility in Mount Pleasant, Iowa. The addendum extends the construction schedule by several months, requiring substantial completion by November 29, 2024 and final completion/closeout by December 31, 2024. It also provides additional specifications related to pull-out tests for the structural retrofit roof sub-framing and approves substitutions for certain roofing components.
The contract opportunity is for the state of Iowa, specifically Henry County. No additional details are provided regarding pricing terms, set-asides, incumbents, funding requirements or sources, or other salient information.
