United Airlines LAX Maintenance Hangar & GSE Complex

This United Airlines maintenance hangar & GSE complex are part of a broader LAX transformation.

This massive maintenance yard expansion was recently completed at the Los Angeles International Airport (LAX).  FSB, and civil partner HNTB, provided longtime client United Airlines with relocation, design and construction services for a new line maintenance hangar and ground services equipment (GSE) complex. This multi-faceted project will consolidate United’s current east and west campuses into a single, state-of-the-art complex at its current eastern location. Now completed, United has a flexible campus containing a line maintenance hangar which can accommodate multiple aircraft ranging from A319 narrow body to B777/B787 wide body aircraft. The GSE building and support shops will enable United’s crews to perform any level of needed maintenance on every type of ground service equipment utilized by the airline, up to and including the largest size of tugs, tractors and buses.

The complexity of the project required multiple phases and the first step was for United to entirely vacate its west campus location. FSB is first retrofitting a west campus hangar bay, which will serve as an interim location for the east campus GSE. Then United’s east-side personnel moved into this temporary facility, and the two existing buildings on the east side were demolished to make a space for the new buildings. This step also required relocation of a World War II-era Quonset hut. The final phase was the construction of the new maintenance hangar and GSE complex and the relocation of United’s personnel into the new buildings.

To meet the additional challenges of this large-scale project, FSB’s team provided on-site construction administration throughout. Check out the construction progress in real time here.
