Situated along the Mission Reach of the San Antonio River, the new Bexar County Public Works Building provided the Public Works Department with much needed space and will accommodate for future growth. The 35,000 SF facility is a showplace for the County and has both open and private office space, a large board room, and break room, as well as staff showers and lockers, truck wash, and ample parking.
The building is conditioned using a 4 pipe chilled water cooling and hot water heating system. The chilled water system is configured with a nominal 150 ton air cooled chiller with primary variable chilled water flow. The hot water system is variable flow and configured with two natural gas, 300 MBTU high efficiency, condensing type boilers with primary variable hot water flow. The building HVAC systems are controlled via a comprehensive DDC (Direct Digital Control) system. The plumbing systems are comprised of sanitary waste and vent, domestic hot and cold water, hot water return, storm drainage and emergency overflow storm drainage, and fire protection consisting of automatic fire sprinklers designed for light and ordinary hazard classifications. The building has a 1200A 480/277 volt, three phase, four wire secondary service. The main distribution board feeds the exterior mechanical equipment, the 480V building distribution system, and normal power to the emergency power system.
