Video depicts multi-stage deconstruction process
|
The Lower Manhattan Development Corporation (LMDC) has released a computer-generated video depicting the yearlong multi-stage process planned for deconstruction of 130 Liberty Street, formerly the Deutsche Bank Building, which was severely damaged during the September 11, 2001, attack on the World Trade Center.
The video, available for download on the LMDC website, illustrates the process step by step from beginning to end. It documents a preparatory work phase, already underway, that involves the erection of scaffolding and elevator hoists around the exterior, the removal of existing netting around the building, and the installation of new netting. This preparatory phase is scheduled to continue for the next two months.
The next phase depicted in the video, interior abatement, is expected to begin in earnest in early 2006. This phase will include environmental cleaning and removal of all interior surfaces and non-structural elements in the building. It is expected to continue through the end of 2006.
The project's third phase, the actual floor-by-floor deconstruction, will also commence in early 2006. The video helps bring this process to life, showing each step involved, from the breakup of floor slabs to the cutting and lowering of interior beams to the removal of exterior column trees. It also illustrates how a buffer zone and abatement zone will be established beneath each floor as it is deconstructed. During this process, all materials removed from the building will be bagged, rinsed, and bagged a second time. The double-bagged materials will be stored in a sealed-off room until and transported away from the site in sealed trucks using approved routes. Most of the hauling will take place on the west side of Ground Zero. This phase is expected to conclude in spring 2007.
Over the course of the deconstruction process, daily air monitoring will be performed to check for materials such as asbestos, dioxins, and metals. Currently, the program includes hourly air sampling seven days a week at 12 locations -- four on the ground, four on the building, and four on surrounding buildings. Results from the monitoring can be found on the LMDC website.
Safety drills for the workers will take place monthly, and updates on the progress of the deconstruction will be available on the LMDC website. In case of an emergency, the Contractor Emergency Coordinator will contact 911. Concerned community members can call a hotline at (212) 587-9337 during business hours or (347) 234-4418 after hours.
