This document comprises construction drawings and specifications for HVAC improvements at Central Michigan Correctional Facility, prepared by the State of Michigan Department of Technology, Management and Budget for the Department of Corrections. The project encompasses Phase 1 mechanical, electrical, and HVAC system upgrades across multiple facility buildings including West Administration, West Food Service, West Housing Units A-B, C-D, and G-H, and East Housing Units L-M and N-P. The scope includes replacement of boilers, installation of new air handling units, ductwork modifications, piping systems, controls integration, and condensing units. Work is divided into priority phases with the West Administration Building designated as highest priority, followed by East Education, West Food Service, and housing unit buildings. The drawings specify that boiler replacements must occur between May 15 and September 30, with all heating equipment fully operational by October 1; the contractor bears responsibility for temporary heating if this deadline is not met. Equipment must be in hand prior to demolition commencement, and the contractor must conduct pre-construction and post-construction testing and balancing of air handling units and associated terminal units.

The contractor is required to attend 6-month and 11-month post-construction warranty meetings with the engineer and owner, track and document recycled materials throughout the project, and provide two facility escorts during work. All work must conform to Michigan Department of Corrections standards and applicable codes including the Michigan Mechanical Code. The contractor shall install tamperproof fasteners in all inmate-accessible areas and coordinate boiler alarm connections to the facility's StarNet 2 system through a designated IT contact. Roof penetrations require new curbs and boots with water-tight sealing to maintain existing roof warranties held by Precision Roofing. The project requires coordination with existing building automation systems and future integration capabilities for all equipment. Specific mechanical notes address piping slopes, condensate drainage, equipment clearances, wall and ceiling patching and painting, and the installation of new equipment per manufacturer specifications to ensure service accessibility.
