About this file
This document is a mechanical demolition plan sheet for Building 105 at Selfridge Air National Guard Base in Michigan, detailing the comprehensive HVAC system removal and preparation for replacement. The sheet includes keyed technical notes specifying six primary demolition tasks: removing existing boilers and circulation pumps, terminating all piping and combustion/exhaust connections, demolishing pressure relief valves, strainers, chemical shot feeders, expansion tanks, and air separators, removing the existing air compressor, potentially removing a VFD controller, and demolishing the existing humidifier. The plan emphasizes contractor responsibilities for off-site disposal, tracking solid waste, maintaining building heating systems during construction, and coordinating with the Contracting Officer and Construction Contracting Officer's Representative (COR) to ensure uninterrupted building operations during the HVAC system replacement process.
