Hartsfield-Jackson Atlanta International Airport – Concourse E Renovation and APM Tunnel Extension

Atlanta, Georgia

This project consists of a new tunnel that extends from the end of the existing tunnel at Concourse E to the new Maynard H. Jackson Jr. International Terminal. The new cast-in-place concrete tunnel accommodates the Automated People Mover (APM) trains, baggage movement, pedestrian circulation, and utilities. The project also includes a new vertical circulation core at Concourse E to access the tunnel. The layout of the new tunnel extends directly below the columns and foundations of the existing Concourse E structure. SDL designed a system of column foundation transfers, underpinning, and shoring which allowed construction to proceed without closing Concourse E.
