Registration has closed for this past event.
The Potomac Yard Metrorail Station site is located approximately midway between the Ronald Reagan Washington National Airport and Braddock Road Stations along Metrorail's existing Blue and Yellow Lines. The area is bordered by the George Washington Memorial Parkway to the east and northeast; the Potomac Greens neighborhood to the south; and active CSX tracks, Potomac Avenue, and Potomac Yard Shopping Center to the west and northwest.
This presentation will focus on the foundation-related challenges encountered and the innovative solution selected by the design-build team. This presentation gives a brief overview of general rigid inclusion concepts, as well as, a case history from the ongoing construction at the planned Potomac Yard Metrorail Station. The case history highlights why ground improvement was the preferred solution on this site, along with the challenges encountered and overcome by removing deep foundation elements. Rigid inclusions are ground improvement elements that blend the gap between traditional deep foundations and shallow foundations on existing soil. By allowing structures to tolerate larger settlement values, rigid inclusions can rely on the sharing of load between the existing soil and rigid or semi-rigid elements to provide a solution that provides more support than shallow foundations on existing soil but with less operational restrictions and requirements than deep foundations.
