About this file
This document is a Construction Bid Addendum No. 1 issued by the Michigan Department of Technology, Management, and Budget (DTMB) for the Saint Louis Correctional Facility Statewide Perimeter Repair/Replacement project. The addendum, dated 8/8/2025, provides clarifications and modifications to the original bidding documents for a comprehensive fencing enhancement project. The bid opening is scheduled for 8/13/2025, with Matrix Consulting Engineers, Inc. serving as the professional consultant. Key modifications include revisions to asphalt removal, grading, concrete work, gate installations, and specific fence enhancements such as replacing aluminum ties with stainless steel ties and installing razor mesh panels on existing double gates.
The addendum includes several critical clarifications, such as specifying that stainless steel plates are required for gate fabric bottoms, confirming that Builders' Risk Insurance will not be required for this project, and providing additional photographic documentation to support the proposed changes. The project appears to be focused on security improvements at the correctional facility, with detailed specifications for gate modifications, fence reinforcements, and structural updates. The addendum suggests a comprehensive approach to upgrading the facility's perimeter security infrastructure, with precise technical specifications for contractors to follow during the bidding and implementation phases.
