LAX United Terminal Redevelopment

CLIENT Los Angeles World Airport

Location Los Angeles, CA

The United Terminal Redevelopment Program consists of the seismic retrofit and expansion of Los Angeles World Airport (LAX) Terminals 7 and 8.

The project includes multiple improvement packages, including the Security Screening Checkpoint (SSCP) Building and Gates 70A & 71A project segment (Package 5A), the passenger loading bridges project segment, and new grease interceptor and sewage ejector facilities.

The SSCP Building and passenger loading bridges include new or retrofitted foundations, where the new foundation elements consist of torque-installed piles. The torque-installed piles are proprietary 12¾-inch diameter displacement-based screwed pipe piles with a closed-end conical tip welded to the bottom of the pipe. The torque-installed piles were installed in three-, four-, or six-pile groups. Shannon and Wilson provided geotechnical design recommendations for the torque-installed piles based on interpreted data from three pile load tests. Pile installation criteria was then developed specific to contractor installation means and methods. Shannon & Wilson subsequently met with the design team and Los Angeles Department of Building and Safety (LADBS) during plan review to facilitate the permitting and approval process of the proprietary installation means and methods. Additional explorations were preformed to satisfy LADBS requirements during the approval process. Following approval, we observed installation of 108 production piles.
