C.1.7. Heating demands at U.S. Army Garrison ALC are satisfied via two means: a Central Heating Plant in B106 and satellite boiler plants in various other buildings. The Central Heating Plant serves Buildings 101, 103, 112, 202, 203, 204, 205, and 207, while the standalone satellite boilers listed in Technical Exhibit 1 serve buildings 108, 403, 404, 406, 504, and 601. C.1.7.1 Central Heating Plant Description: The High Temperature Hot Water (HTHW) generators and all auxiliary equipment (including water makeup and feed equipment, pressure tanks, fuel oil transfer pumps, fuel oil polisher and circulating pumps) are located in the Central Utility Plant in Building 106, a 24,000 square feet building. The approximate age of the Central Heating Plant is 44 years and it comprises a combination of new and adequately maintained legacy equipment. The system was originally designed as a variable flow system operating at a temperature differential of 150 degrees Fahrenheit (F), a supply temperature of 400 degrees F supply and a 250 degrees F return. The plant currently operates at a lower supply temperature. The plant's heat sources are direct-fired, dual fuel HTHW generators. The expansion of the heated water is taken up in two (2) nitrogen expansion vessels, which simultaneously pressurize the system. The circulating pumps located in the Heating Plant distribute high temperature water to the aforementioned buildings through an underground closed loop distribution system. The campus distribution system comprises supply and return pipes under the same basic pressure. Shell and tube heat exchangers located in each building transfer heat from the primary high temperature water to the lower temperature secondary systems. Each HTHW pump has sufficient capacity to circulate the full rated flow capacity of its associated HTHW generating unit against a full system pressure drop. Pumps are single stage, end suction, centrifugal type especially designed for high temperature hot water service. These pumps circulate water through the individual generating units and the distribution system. Flow through the distribution system varies with the heating load. High temperature two-way control valves, control the flow of HTHW to the heat exchangers, as required to maintain low temperature hot water set point on the low temperature side of the heat exchangers. As the load increases, the heat exchanger control valves open and take more water. Contractor shall note that at the time of this solicitation the Fuel Oil Delivery and distribution system is being replaced. The new Fuel Oil transfer pumps, fuel oil polisher and auxiliary components will be installed and fully function by April 2018. The equipment schedules accompanying this PWS are capturing the specified equipment that will be installed, which the Contractor shall maintain as part of this contract. C.1.7.2 Stand-alone Satellite Heating Boilers: The satellite boilers provide constant volume flow Low-Temperature Heating Water (LTHW) through pumped closed piping system to air handling units and other terminal equipment throughout the building or steam to heat exchangers. Hot water heating plants include gas, oil or dual-fired boilers. C.1.8.
