World Trade Center, Greenwich Street Corridor

The Greenwich Street Corridor refers to the extension of the New York City subway system (1 and 9 lines) that formerly ran below the World Trade Center. The track route follows the former Greenwich Street that was partially removed to construct the original World Trade Center Complex. The Greenwich Street Corridor Project involves removing soil, rock (schist) and large pieces of the former trade center slurry wall, to develop the new World Trade Center Complex.

Excavation activities for this project are restricted by a variety of structural issues and removal of materials is severely hampered by the logistics of working within a large excavation. Materials are removed by the crane load to waiting transport vehicles that deliver the material to a variety of recycling facilities in the tri-state area. This prompts the need for complex transportation planning and tracking; all of which is handled by a qualified Disadvantaged Business Enterprise (DBE). To date, over 100,000 cubic yards of material have been removed and an additional 50,000 cubic yards are scheduled for removal.

Having been part of disaster response activities in 2001, Impact Environmental is proud to part of the large team of contracting and design professionals that will be involved in the rebuilding of this iconic structure.
