The blast-proof glass pavilion of the Fulton Street Transit Center, NY, features a zinc clad open dome, with an oculus, and a cable suspended panelized sunlight deflection system used to light the lobby, mezzanines, and concourse, which mirrors the oculus opening. An inner-cat-walk encircles the installation, which is pre-assembled off-site using pre-tensioned cabling, and then suspended from steel strut-work, with a 75 man team, and two cranes to suspend the hour-glass shaped skeleton some 60 feet.
The panels are faceted into a diamond pattern, and mill-finished to reduce glare. Sunlight is directed to the panels from adjustable reflectors positioned just below the oculus glazing system. Earlier renderings show the pavilion without its dome – a glass box, which was removed from the design, but subsequently added back when Stimulus funds were granted the project.
Some of the challenges for this project were:
coordination of WTC Hub, and Concourses
complex curtain wall systems
sophisticated materials and cutting-edge designs
coordination with public agencies & service providers.
a mid-project change order (MOD54), which added considerably to the LCD and passenger information system
programs, and to the infrastructure and wiring to support the work.
historic preservation and integration of historic 19 c. Corbin building into the hub-system
rebaselining of original schedule
implementation of recovery schedule
