The Southwest Airlines HOU Tech Ops Maintenance Hangar is a new hangar at William P. Hobby International Airport, built to support Southwest’s new fleet of 737-MAX 800 aircraft. The facility is located on a 40-acre site at the south end of the airport and consists of the 240,000-square-foot hybrid pre-engineered metal building structure, 460,000-square-foot of apron pavement, taxi lane, Ground Support Equipment paving, aircraft wash facilities, employee parking and all supporting site utilities and improvements. The hangar bay is approximately 142,000-square-feet which is large enough to fully enclose six 737-MAX 800 aircraft simultaneously and includes overhead bridge cranes, maintenance tool enclosures, aircraft utility pits, and an advanced low-expansion foam fire protection system with trench drains. The remainder of the hangar consists of office space, stores facilities, and numerous specialized maintenance shops. The apron paving is designed to accommodate 12 additional aircraft outside of hangar facilities.
In addition to the hangar project, McCarthy managed several enabling projects in agreement with the City of Houston and Houston Airport System (HAS), which preceded and facilitated the hangar project. These consisted of relocating existing FAA and HAS fiber communication lines, demolishing existing HAS facilities on the hangar site, constructing a storm water management structure, and relocating three FAA airfield navigational aids.
