The Challenge

  • The movement of the adjacent existing tunnel was a concern due to the unbalanced earth load of the excavation
  • Excavation in variable consistency ground is suspect to unexpected behavior, such as sudden deformation or ground collapse

The addition of Maynard H. Jackson International Terminal at Atlanta’s Hartsfield-Jackson International Airport required the expertise of various companies and professionals. As part of the expansion, the Automated People Mover (APM) trains needed to be extended from Concourse E to the new international terminal.

The Solution

The project team chose a proactive and cost-effective approach to managing the open-cut excavation of twin tunnels using Geocomp’s iSiteCentral® real-time monitoring program. The system provides early warnings of unacceptable or surprise performance in time so that protective measures can be implemented to stop the undesirable performance or reduce the consequences.
