Abstract:

The Port Authority TransHudson Corp. (PATH) is renovating and expanding Exchange Place station, the first stop in New Jersey across the Hudson River from lower Manhattan. To be completed by 1989, the reconstruction project will provide a new entrance for the 80 year old station, including a new substation and ventilation building, which will be part of an innovative tunnel ventilation system. The new 86 by 114 ft entrance building, which is being built over the four existing shafts at the station platforms' east end, will have a waterfront deck abutting the New Jersey city park pier along its south boundary. The west facade, flanking a new access street, will serve as the entrance to the grade-level concourse and fare control area. Fixed glass window walls will look out on the river and lower Manhattan skyline. The station entrance building and deck are supported on 14 in. dia closed end concrete filled pipe piles. A new bulkhead will be built since test pits failed to uncover any remains of the old wooden bulkhead. The new 24 in. thick wall, to be built using slurry construction, will also support the building and deck as a retention structure. The escalator and stair shaft construction to extend through 40 ft of soil and 35 ft of rock, will be done inside a cofferdam.
