Replacement of Hot Temperature Hot Water (HTHW) Line D at WPAFB

Design / Bid / Build includes all labor, equipment, and material to replace the existing Steam/High Temperature Hot Water (HTHW) heating distribution system with a natural gas fired heating system. Project provides new building/mechanical space and all utilities and controls required to support natural gas boilers. Provide new natural gas fired boilers and all associated piping, valves, DDC controls, and equipment including connections to existing facility heating distribution systems. Work includes tie-ins, demolition, and capping/sealing of existing steam and HTHW piping, hot water heat exchangers, and low-pressure steam reducing stations. Repair Steam and High Temperature Hot Water (HTHW) Line D partial in Area A using Natural Gas (N.G.) Boilers for 22 buildings. Includes new 8" diameter N.G. supply piping and in most cases separate N.G. boilers at or adjacent to each building. Affected facilities are buildings 15, 16, 17, 19, 21, 22, 23, 27, 28, 29, 55, 69, 109, 110, 113, 138, 140, 142, 143, 151, 152, 219, and infrastructure facilities 07199 (Heat distribution mains) and 07187 (natural gas mains). This project addresses roughly ½ of facilities served by existing heat distribution Line D.
