The decontamination of 130 Cedar Street begins in late July 2007, according to project spokesperson Chris Colbourne. Colbourne, vice president of Masterworks Development Corporation, presented the project scope to Community Board 1 (CB1) on July 9th.
Colbourne's team has planned the 12-story building's decontamination with the Environmental Protection Agency and the city Department of Environmental Protection to insure its safe cleaning. Project managers are now in the midst of background air sampling around the building, located on Washington between Cedar and Albany Streets, and expect crews to begin the cleaning process within weeks.
Under the plan, every surface of the building will be cleaned and inspected from the top down using a four-floor "buffer zone" between the clean floors and deconstruction areas (similar to that of 130 Liberty Street). The deconstruction will strip the building to its concrete superstructure, and undamaged concrete elements will be reused for the building's redevelopment.
The decontamination will continue through February 2008, with eight air monitors around the perimeter in place throughout the project. The building will remain enclosed by netting, and work will be carried out under negative air pressure to contain all particulates. Should the air monitors register an elevated particulate reading, work will be halted immediately until the situation is resolved.
Workers will wear full protective gear for decontamination work and enter and exit through a secure passage to contain any contaminants. Environmental and building inspectors will constantly monitor the decontamination for the benefit of both workers and the community.
Additionally, inspectors from the Office of the Chief Medical Examiner will search for potential human remains in the space between 130 Cedar Street and neighboring 90 West Street. That search should be complete by late July 2007.
Partial building deconstruction will follow by spring 2008. The redevelopment will add seven stories to the top of the 1930s skyscraper, raising it to 19 stories (including a penthouse floor). The new building will house a new hotel with retail and restaurants.
Construction manager Laval Construction is coordinating the project with the Lower Manhattan Construction Command Center and the Port Authority of New York and New Jersey -- particularly with regard to the 130 Liberty Street deconstruction and future World Trade Center Vehicular Security Center, to be located underground at Liberty and Washington Streets.
