GK Engineers provided full MEP design for the Terminal Apron Hangar Replacement at Sugar Land Regional Airport, a TxDOT Aviation project delivered through KSA Engineers. The roughly 40,000 SF hangar replaced one removed for the airport’s Taxiway A relocation and includes the aircraft bay, fire pump room, electrical room and toilet rooms.

The hangar is mechanically ventilated to keep fuel vapors from building up, with high-velocity fans for circulation. An 800A, 480V service feeds the building through a service-rated manual transfer switch so a roll-up generator can carry the hangar through extended outages after a hurricane. Roll-up ground power stations charge aircraft, in-slab grounding points discharge static, and trench drains run to an oil-water separator.

Design ran from March 2019 to May 2020, and GK handled RFIs, submittals and site visits through construction in 2021 and 2022, including a high-bay fixture substitution during the post-COVID supply crunch that kept the light distribution. The hangar opened in 2023.
