This is Construction Bid Addendum No. 1 issued by the Michigan Department of Technology, Management and Budget (DTMB), State Facilities Administration Design & Construction Division for the Bellamy Creek Correctional Facility Paging System Replacement project (File Number 472/24264.JGH). The project involves replacing the existing paging and audio distribution system at the correctional facility with a new system utilizing the existing Cisco network infrastructure. The addendum was issued on July 23, 2026, with a bid opening date of July 29, 2026. The professional managing the project is Commtech Design, Inc., with Jared Gavin-Helfrich serving as Project Director. The addendum includes revised drawing TC303 showing the paging system replacement schematic connectivity with symbol 'WA' indicating the core paging system connection point in the Admin building.

The addendum addresses seven contractor inquiries and provides four clarifications regarding project execution. Key clarifications include Sally Port access hours (7:00 AM to 3:00 PM, closed 10:43 AM to 11:30 AM), manlift requirements for maintenance spaces with specific flooring protection, and conduit installation specifications for housing units 1 through 7. Contractors are permitted to bring gators or small UTVs to the site, store materials in secure areas overnight with proper custody approval and inventory logging, and utilize existing cable raceways for new cabling. The work scope includes removal of existing speakers, paging amplifiers, and microphones; installation of new speaker cabling routed through existing conduits; configuration of 70-volt and 8-ohm amplifier systems; and installation of network equipment including terminal strips, patch panels, and Ethernet switches. Acknowledgment of this addendum in the bid submission is mandatory, with failure to acknowledge serving as grounds for bid rejection.
