PROJECT BACKGROUND
Infrastructure Associates was commissioned by the City of Houston General Services Department to provide the design of a new emergency power system for Fire Station’s 18, 19, and 36. Previously, each station had a 45-kW generator that served life safety load and a small number of stand-by emergency loads through an ATS and emergency panel. The city asked IA to design a new adequately sized emergency system that would serve the entire building. ELECTRICAL DESIGN Infrastructure Associates Engineers performed a system load analysis for each fire station to determine the correct size of the generator. From this study, it was determined that each station would require a new 100-kW natural gas generator. The existing electrical service was completely rehabbed to accommodate this mode of operation. A service entrance rated Automatic Transfer Switch replaced the main disconnect of the building, and provided a utility company connection as well as a connection to the new generator. IA provided all required site and floor plans for the location of the proposed generator, reworking the existing electrical distribution system, schedules for all conduits and panelboards, equipment, and size of the gas line required for the generator at all three stations. |
