NYC 9/11 Public Portal Document

Environmental Site Characterization — Façade Report Fiterman Hall — 30 West Broadway, New York, NY Airtek Project 05-0867 — January l0, 2006

Airtek Environmental Corporation (Airtek) has been retained by Pei Cobb Freed & Partners, Architects, LLP (PCFP) on behalf of the Dormitory Authority of the State of New York (DASNY) and The City University of New York (CUNY) to conduct an environmental characterization study of the Fiterman Hall Building located at 30 West Broadway, New York, NY (Fiterman Hall, the Building, or 30 West Broadway). The Building is a 15-story, 370,000 (SF) classroom building owned by CUNY and operated prior to 9/11 by CUNY/Borough of Manhattan Community College. For purposes of the environmental decontamination and deconstruction of Fiterman Hall, DASNY is acting as and for the Building owner. The building was physically damaged by the collapse of 7 World Trade Center, and impacted by the environmental effects of the entire World Trade Center Collapse.

This report is focused on the facade of the Building. A characterization report detailing conditions interior to the Building has been prepared under separate cover.

1.1 Purpose and Objectives of the Facade Characterization Study

DASNY/CUNY insists that appropriate environmental safeguards are put in place at 30 West Broadway to protect workers and the public both during the planning stages of the project, and during the abatement and demolition phases. In support of this effort, it is necessary to closely examine both the structure and building components of the Fiterman Hall Building, and the residual impact of the dust disseminated by the collapse of the World Trade Center (WTC).

The primary focus of the instant investigation and report is the suitability of the building facade as a component of the containment system that will allow the safe and controlled abatement and removal of both building components that pre-dated 9/11, and the dust and dust-impacted building components that remain.

Considerations investigated included the following:

Integrity and construction of the facade as it relates to the facade's use as a barrier during abatement

Confirmation of the efficacy of the NYC DEP cleaning of the exterior facade of the building post-9/1 1

Asbestos-containing building materials potentially existing on and within the facade

Lead-containing or lead-painted components on and within the facade

The potential for WTC Contaminants of Potential Concern (CoPCs) both on and within the facade construction

The physical and environmental state of the "Gash Area," where the building was physically damaged by the collapse of WTC 7
