About this file

Written by GovTribe AI · Apr 3, 2024

This document is a set of plans and specifications for the replacement of the HVAC system in Building 300 at the Gus Harrison Correctional Facility in Adrian, Michigan. The project involves the replacement of the existing air handling units, controls, piping, and associated equipment. Key details include the replacement of 5 air handling units, various pumps, and a new air-cooled condensing unit. The electrical work includes the replacement of existing disconnects, motor starters, and the connection of the new mechanical equipment. The project is being managed by the State of Michigan and Lenawee County. Bids for this project are due by 2:00 PM on a specified date, and the project specifications indicate that all work must be coordinated with the Owner and Temperature Control contractor.

The pricing terms and funding sources are not explicitly stated in the provided documents. However, the documents indicate that the work is a state and local contract opportunity, suggesting competitive bidding requirements. The documents do not mention any set-asides, incumbent contractors, or specific funding amounts or sources. The contract term and any renewal options are also not specified.
