E2PM was retained as a subconsulting party to support portions of a multi-year NJ Transit $175 million redevelopment and rehabilitation project at the Hoboken Terminal and Yard Complex Redevelopment in Hoboken, New Jersey.  

E2PM was selected by its client to be a part of a large design team involved in several projects throughout the redevelopment/rehabilitation of the site in three phases. Projects completed included the rehabilitation of the terminal’s main waiting room; the modernization of Yard B; the construction of a new Wheel True Building and the rehabilitation of the Ferry Terminal.

E2PM’s direct involvement included providing civil, geotechnical, structural, and environmental engineering services for a single-story, 220 foot-long, 6,000 square foot building constructed to serve as the new wheel truing facility.  The project involved dewatering of deep foundations situated in complex subsurface conditions in close proximity to the Long Slip Channel. The geotechnical and structural complexities required special consideration in preparing the dewatering calculations and design drawings. Soil and groundwater contamination was identified within the construction area. 

E2PM analyzed and designed the dewatering system, which included a series of groundwater extraction wells both on the inside of the excavation and outside. The extracted groundwater required treatment before disposal. E2PM also identified the requirements from the treatment of groundwater. A NJDEP temporary dewatering permit was prepared and obtained.

E2PM also sampled the groundwater during the dewatering phase. Four (4) submerged pumps were designed to dewater the excavation and to keep the groundwater below the bottom of excavation. Observation piezometers were installed to monitor the groundwater elevations during construction.

In addition to the dewatering design of deep foundations, E2PM designed the groundwater treatment system. The system included activated carbon for VOC removal and sediment filters for suspended solids removal. An oil/water separator was available on site to remove any LNAPL. A groundwater sampling program was incorporated to insure compliance with the dewatering permit.
