About this file
This document is a detailed heating plant piping diagram for the Selfridge Air National Guard Base in Michigan, specifically for the repair of HVAC systems in Building 105. The diagram provides a comprehensive technical schematic for new heating hot water boilers, including components such as boiler circulation pumps, air/dirt separators, isolation valves, temperature and pressure relief valves, condensate traps, and acidic condensate routing to a neutralization tank. The piping diagram shows the interconnections and layout for high-efficiency condensing boilers with stainless steel heat exchangers, designed to be installed in a lead/lag configuration with associated pumping and control systems. The technical drawing is part of a solicitation (W50S8525BA003) for the Michigan Army National Guard, detailing the precise mechanical engineering specifications for replacing the existing heating boiler systems in the facility.
