Critical Transportation Link Severed by 9/11 Terrorist Attacks

On September 11, 2001, terrorist attacks destroyed the twin towers of the World Trade Center (WTC) and heavily damaged the WTC's Port Authority Trans-Hudson (PATH) station. Because the station was in dire need of repair, service to Lower Manhattan was suspended until November 23, 2003, when a temporary station opened, reestablishing the critical link between Lower Manhattan and Jersey City.
In 2003, the Port Authority of New York and New Jersey selected the Downtown Design Partnership (DDP), in association with renowned Spanish architect Santiago Calatrava, to design the $3 billion permanent WTC transportation hub, also known as the PATH Terminal. This partnership is led by the joint venture of DMJM + Harris and STV Group, Inc. Parsons is an equal partner in the DMJM/STV joint venture and a prominent member of the DDP, which is undertaking this unique terminal design. The Parsons team plays a key role in the transportation hub design and is responsible for the following tasks:
  • Oversee the infrastructure group design (civil, structural, geotechnical, underpinning, survey, and environmental) during the preliminary design.
  • Directly manage 9 of the 19 final design packages, including all the early fast-track designs (New York City Transit 1 Line Subway underpinning system, east–west connector, underground ventilation structure, and Route 9 underpass tunnel structure).
  • Serve as the customer's "specialty consultant" to review security/blast-protective designs, including countermeasures that cover chemical, biological, and radiological threats.
  • Oversee the project's overall safety program.
  • Provide all communication and systems designs.
  • Provide the mechanical design for the transportation hub's state-of-the-art skylight providing constructibility oversight/risk management and estimating support.

Soaring Design for New Transportation Hub

Mr. Calatrava envisioned the new terminal as a dove rising from the ashes of the devastated WTC site. The new transportation hub was designed to resemble a bird in flight as it is released from a child's hand, with its wings made up of the two 150-foot-tall canopies and its body represented by the hub's steel-ribbed arches.
Work on the preliminary design began in 2003 and was completed in 2005. The final design was completed in October 2010.

New Transportation Hub Rises from 9/11's Ashes

This full-service transportation network will dramatically improve travel for commuters because of its seamless connections to PATH trains, city subways, ferries, and the financial district. The 650,000-ft² WTC transportation hub will be fully climate controlled, and its featured "openness" will provide passengers with a sense of security, as well as a clear visual orientation to both the interior and exterior building functions. The hub's facilities will incorporate sustainable design, including natural light (where possible), conformance to the Americans with Disabilities Act, and state-of-the-art security strategies and blast-resistance measures. In addition to the stunningly original architecture, the hub will showcase numerous significant structural features, especially the long-span, shallow parabolic arches supported by long Vierendeel trusses.
When completed in 2014, the new world-class, multimodal transportation facility will serve as many as 250,000 commuters daily.
