Design and Evaluation of Ground Support for the Exchange Place Station Improvements Project
Publication: Geotechnical Engineering for Transportation Projects
Abstract
On September 11, 2001, terrorists attacked New York City resulting in the collapse of the World Trade Center (WTC) towers. This event also severed a vital regional transportation link between New Jersey and lower Manhattan affecting nearly 67,000 daily commuters. On September 12, 2001, the Port Authority of NY & NJ (PANYNJ) set in motion, even as rescue efforts continued, plans to restore downtown commuter train service to its former Port Authority Trans-Hudson (PATH) WTC Station. This paper focuses on the Exchange Place Station Improvements Project, which was one of three components of PANYNJ's Downtown Restoration Program (DRP). Design of this project required underground rock excavations with spans upwards of 18 m (60 ft), rock cover as low as 7.4 m (25 ft) and existing buildings overlying planned excavations. Recommended ground support consisted of pre-stressed rock bolts, pre-fabricated lattice girders and steel fiber reinforced shotcrete (SFRS) linings.
