Saiful Bouquet is providing full structural engineering services for the replacement concourse at Los Angeles International Airport. The T3 Concourse Replacement Terminal Course at LAX is a three-level steel framed replacement of the existing steel framed concourse.
The location of the new steel columns are located over an existing irregularly shaped concrete basement and tunnel that are required to be operational during the construction phase. Concrete over metal deck is supported by steel beams and steel columns. The lateral force resisting system consists of steel special moment frames in both directions. Seismic joints separate the new concourse from the existing head house. The design of the lateral force resisting system poses some challenges due to the height of the steel columns. The foundations consist of a combination of shallow spread footings and torque-down piles.
