This project consisted of the installation of four new 1,100 Ton chillers in the existing satellite central utility plant (SCUP) at Hobby Airport in Houston, TX. Upon completion of the SCUP, the existing Central Utility Plant (CUP) was decommissioned and demolished. The new chillers, cooling towers, and pumps allowed for N+1 redundancy in the SCUP. The new chilled water system was configured as a variable primary system with one set of variable secondary pumps serving the FIS Terminal. A bypass around the FIS secondary pumps was constructed to allow the primary pumps to serve the FIS when differential pressures and load allow. Our team developed a Method of Procedure (MOP) for transitioning the chilled water systems from the existing plant to the new SCUP that would allow us to test the SCUP without impacting normal airport operations.
During the project, our team was able to pretest the CW system while the SCUP was isolated from the terminals, but we were unable to test the new chillers without load from the airport. CCLLC developed a MOP that allowed our team to test the new chillers with the loop opened to the terminals, in incremental steps, over the span of several days. This required careful planning, close coordination with airport operators, a well-staffed project team, and maximum efficiency on the part of our team to ensure everything was properly tested in the short windows of time we were given. Each night we would take the existing plant offline, open the loop to the SCUP, perform the procedures we had planned for that night, take the SCUP offline, isolate the SCUP from the airport, and put the existing CUP back into operation all between the hours of 10pm and 4am.

The George Bush Intercontinental Airport Terminal Redevelopment Program (ITRP) is the largest capital improvement program in the history of the Houston Airports and consists of three projects: Mickey Leland International Terminal (MLIT), Enabling Utilities Landside (EUL), and Federal Inspection Services (FIS) renovation and expansion projects. The MLIT project is comprised of multiple subphase projects – relief/refresh phase of the gates and gate areas in the existing terminal D area, C-D connector phase (long corridor that connects terminal D to the C-D Knuckle), C-D knuckle phase (renovation to the concessions area where the connectors to terminal C and terminal D meet), new D West Pier (construction of an all new terminal area housing new gates for international flights), and sterile corridor (long corridor that moves passengers from international flights through customs and border protection before allowing them access into the rest of the airport). The FIS project will take the terminal processing functions for the international flights, currently located inside terminal D, and relocate it into a new expansion on the existing FIS, which also includes the renovation of much of the existing FIS. The EUL project is a new water production plant site for domestic water and sewer utilities for terminal D. CCLLC led a Cx team, including subconsultants, responsible for MEP, F/A, Access Control, BECx, and TAB Verification. We provided technical Cx services per IECC 2015, LEED v4.1 pre-requisite on energy consuming mechanical, electrical, and plumbing systems and Enhanced Monitoring-Based Cx.
