Building Exterior Clean-up

Scope of Work All work performed shall be in compliance with all applicable, relevant, and appropriate regulations, including but not limited to those of the United States Environmental Protection Agency (USEPA), the United States Department of Labor Occupational Safety and Health Administration (OSHA), the New York State Department of Labor (NYS DOL), the New York State Department of Environmental Conservation (NYS DEC), the New York State Historic Preservation Office (SHPO), the New York City Department of Sanitation (DOS), the New York City Department of Health (DOH), the New York City Landmarks Preservation Commission (NYC LPC), and the New York City Department of Environmental Protection (DEP).

Background The DEP with assistance from representatives of the NYS DOL and US EPA performed follow-up site visits at buildings in the vicinity of the World Trade Center. The visual assessments disclosed the presence of various amounts of debris with various dispersal patterns at the building exteriors. The majority of buildings had isolated areas of debris specifically at the perimeter of the roofs, at the base of parapet walls, and in gutters. Debris was also visible at horizontal surfaces on some of the building facades. For some buildings, building facades facing the street were cleaned while the facades at the rear remained dirty.

The observed debris was characteristic of the debris from the impact of September 11, 2001. The debris appears to have reformed into a dense mass (caked). During the DEP follow-up visits, samples of the debris were collected from various roofs. The uneven dispersal identified above was also evident in the sample collection. Samples collected from various buildings indicated that some of the debris was asbestos-containing material (ACM). Based on these results and the most stringent assessment and evaluation, this material may be ACM and shall be cleaned by NYS DOL licensed contractors with DEP and NYSDOL certified workers.

Purpose A NYS DOL licensed asbestos contractor with DEP and NYSDOL certified workers shall perform the clean-up of building roofs, setbacks, and/or building facades within the vicinity of the WTC. The scope of work for the clean-up activities is attached. The clean-up activities shall consist of collection of debris and wet cleaning/HEPA vacuuming until the surfaces are clean of visible debris.

Contract Term and Specifications The contract shall be in force for 120 consecutive calendar days from the DEP commencement date. Services shall be directed by the DEP. Contractors shall be prepared to mobilize within 72 hours of the contract award. The DEP expects contractors to provide four to five crews with a minimum of five handlers per day at each of the areas. Multiple building roofs shall be cleaned simultaneously.

Work shall not be performed at any building found to be structurally unsound. Page 1 05/03/02
