Key for Table FT Asbestos Floor Tile Under Cabinet

The scope of abatement for Project Group EES1 includes all asbestos floor tile under cabinets from throughout the identified areas of the building.

The Contractor will be allowed to construct multiple negative pressure enclosures for the complete removal of all of the materials detailed in the “Abatement Activities” for Project Group EES1.

1. The Contractor is responsible for all of the materials listed in the “Abatement Activities” located inside of the project areas. The project areas include all portions of the functional spaces listed in the “Summary of Locations” table. When present in, connected to or adjacent to the room, materials located in bathrooms, closets, storage rooms, and below fixtures (such as radiators, cabinets and bookcases), behind furniture and inside sink cabinets, flooring materials are included when exposed by pre-abatement demolition activities. Additional descriptions for certain areas are listed below:

• Material Below Cabinets/Casework: The Contractor will be responsible for all asbestos materials found below cabinets/casework in the spaces identified. The Contractor will not be responsible for the demolition of cabinets/casework.

2. The regulated areas will be emptied of furniture, furnishings and moveable objects prior to the start of the project. This activity will be completed by the Owner.

3. All regulated enclosures established for the removal of asbestos flooring materials only will be set up in accordance with the following minimum guidelines prior to the start of any abatement activities:

• Asbestos banner tape and asbestos warning signs will be set up extending to a minimum of 8’ in all directions from the asbestos floor tiles.

• Critical barriers, constructed of a minimum of one (1) layer of six-mil polyethylene sheeting, will be placed over all ceiling return vents, bookcases, lockers and all items which cannot be decontaminated in each of the regulated areas.

• A minimum of one (1) layer of six-mil polyethylene sheeting will be placed over all wall surfaces, counters and other non-floor surfaces inside the regulated areas.

• A minimum of one (1) layer of six-mil polyethylene sheeting will be placed over all non-asbestos flooring inside of the project areas THE CONTRACTOR WILL BE RESPONSIBLE FOR ANY DAMAGE

TO ADJACENT FLOORING MATERIALS.

• For project areas where the amount of materials removed is greater than 10 square feet or 25 linear feet, a minimum of one (1) air filtration devices (AFDs) will be required in each functional space in excess of 400 square feet. This minimum number of machines is desired to create a minimum negative pressure of 0.02 inches of water equivalent, sufficient air changes and appropriate air flow through the enclosure. The Contractor will be responsible for properly securing the exhaust tubes in any exterior windows and/or doors used for exhaust locations.

• For project areas where the amount of materials removed is greater than 10 square feet or 25 linear feet, a three-stage decontamination chamber will be required. The decontamination chamber will be connected at a location convenient to building access and waste out activities and will be coordinated on-site. A black polyethylene barrier will be placed in front of the decontamination chamber to provide an additional visual barrier to the work area.

• In addition to the minimum requirements listed above, all work will be conducted in accordance with all requirements of AHERA and all applicable provisions of the OSHA Asbestos Standard (1926.1101(g) - “Methods of Compliance”.
