About Project
Central Plant and Utility Distribution System Expansion, A multi-prime, multi-contract project that expanded the City of Houston’s Bush Intercontinental Airport’s central plant and utility distribution system spanning a 10-year design & construction schedule with a total budget of over $150 millions. The expansion represented a net distributed capacity increase of 9,000 tons cooling to 23,000 tons and 90,000 MBH heating to 190,000 MBH along with corresponding increases in both electric and gas utility distribution. The project installed various Motor Control Centers, 5kV motor starters, electrical duct banks, cable and conduit for power and control circuits. The project included (2) new synchronous drive chillers, (2) new steam turbine drive chillers, retrofit of (3) existing steam boilers, replacement of (3) existing superheated steam boilers, and associated ancillary pumps, cooling towers, heat exchangers, etc. The project installed over (2) miles of pre-insulated underground piping and upgrades several miles of existing utility tunnel piping. Noteworthy of this project was an airport wide building controls system upgrade to BACnet compliant systems under multi-vendor contracts.
