PANYNJ Contract: PAT-784.162: Hoboken Flood Resiliency
A detail phasing plan for all the work was develop to minimize the impact to the public. This included only shutting down one staircase at a time to provide optimal flow to the Hoboken Terminal. Work was scheduled in five phases. Coordination with PATH and NJ Transit was critical throughout this process.
Gramercy oversaw all aspects of the project including:
- Electrical, Communications & Fiber Optics
- CMU and Tile Installation
- Plumbing, HVAC & Mechanical
- Concrete Formwork & Steel Reinforcement
- Structural Steel
- Roofing & Waterproofing
- Installation of ILC Dover Fabric Flood Barrier
Demolition of the existing stair bulkhead, stairs and mezzanine floor were all self-performed and completed. The use of our bobcat fleet expedited this work.
The installation of flood doors at the bottom station entrances involved the modification of the structure. This involved the selective demolition, shoring and placement of new structural concrete. In addition, one staircase involved complete demolition and restoration of the stair bulkhead.
Gramercy installed four (4) Walz & Krenzer watertight doors ranging from 1,500-5,600 LBS. Each flood mitigation door was design to withstand the new flood elevation levels set by FEMA. We over saw our Disadvantaged Business Enterprise (DBE) subcontractor in the installed one (1) ILC Dover horizontal fabric flood barrier. Each flood device was tested to the flood elevation which was approximately 13’.
Hoboken Flood Resiliency Project received an award from the New Jersey Alliance for Action as one of the leading infrastructure projects in New Jersey on February 17, 2021.
