NYC 9/11 Public Portal Document

The general procedures to be used for this project, in general order, are:

PHASE I: North side of 130 Liberty Street. Approximately 6,000 sq ft of ACM dust and debris per floor per floor

1. The existing decon is the property of others and will be removed prior to the commencement of this work. This contractor will provide its own personal and waste decons, as well as a document recovery decon, in the same general locations as they presently exist on Level “A”. Locations are indicated on attached drawings. 2. Seal any openings to Car #24 on all floors other than the work area floors (work area includes floors 8 through the 24 floor) using hard barriers with the seals caulked airtight. 3. Construct a hard barrier, with all seals caulked airtight, inside Stair #2 between level “A” and the first floor. This stairwell shall then be used to traverse from “A” and “B” levels during and after the abatement process. 4. Construct isolation barriers to separate proposed north side work area from the rest of the building. Barriers should be erected to connect the existing safety partition from the exit of Car #24 to the north side barrier wall on each floor. 5. Construct two stage airlocks on each floor to separate the security elevator lobby from the work area. 6. Set up negative air units in elevator lobbies, north of the barrier, and wherever else needed to maintain air quality or as directed by the Environmental Consultant, as well as all other temporary lighting and power necessary to perform the work. 7. Prepare the work area including sealing of all isolation barriers (including all openings to the underfloor cell system) and capping of all HVAC duct work. 8. Clean all gross debris from the work area and remove as asbestos contaminated waste. Work will begin on the uppermost floor (24”') and contractor will work down. 9. This contractor shall recover all files, books and documents from within file cabinets and desks and shelves at each cubicle, office, closet or along corridors and shall place the contents in cardboard boxes, and shall label each box indicating its location of origin. Each box shall then be double bagged and moved to a pre-agreed location on the first floor. Contractor shall provide the owner with 5 sets of floor plans indicating the origin and final location of each box.
