The new 15-gate West Gates Terminal serves as an expansion of the Tom Bradley West International Terminal. It is connected to TBIT by a 1,000-ft-long underground pedestrian tunnel with moving walkways, in addition to a separate utilities tunnel for baggage and services. The façade system includes a mix of metal panel and glazing systems with integrated structural support system that is cost-effective and performance driven. The concourse features a curvilinear metal roof structure with clerestory glazing to maximize daylighting. A three-story insulated glass façade blends seamlessly into the curved roof structure with a unique interface to the curved ceiling on the interior. West Gates features three feature picture windows, which provide expansive views and daylight. The windows are up to 50-feet high and incorporate two moment frames at the end of each opening to provide lateral stability for seismic movements.
