Based on the currently recommended sampling and analytical procedures, Airtek recommends
that additional sampling is necessary, in order to determine the asbestos content of building
materials.
3.0 SUMMARY OF AIRTEK ENVIRONMENTAL'S INSPECTION RESULTS:
The asbestos inspection was conducted on 5/26/05 & 5/27/05 and involved a thorough visual
examination of all areas and sampling of suspect materials that would be impacted during the
proposed demolition.
Airtek Laboratory analysis confirmed the presence of asbestos in the amount greater than 1%
within the samples collected from the following material:
1. Flashing
2. Bulkhead Tar
3. Roofing Material
4. Coping Stone Caulk
5. Window Caulk
6. Aircell Pipe Insulation
7. White Block Pipe Insulation
Airtek laboratory analysis determined the samples collected from the following materials to
contain less then one percent (<1 %) asbestos.
1. Brick Mortar
2. Coping Stone Mortar
3. Window Glazing
4. Wail Plaster White Coat
5. Wall Plaster Brown Coat
6. Ceiling Plaster White Coat
7. Ceiling Plaster Brown Coat
8. Rubber Tile Mastic
9. Sheetrock & Joint Compound
10. Cementitious Duct Insulation
11. Tile Grout
4.0 CONCLUSIONS AND RECOMMENDATIONS:
Asbestos-containing materials, which will be affected by the scope of work, have been positively
identified at various locations throughout the building(s).
Proper asbestos abatement procedures shall be implemented prior to the commencement of
demolition work. All asbestos abatement work shall be performed in accordance with all
applicable Federal, State and Local rules and regulations. The abatement project shall be filed
with all agencies having jurisdiction over this project, such as USEPA, NYSDOL and NYCDEP.
. A licensed abatement contractor must perform the removal of all friable and non-friable ACM.
Airtek believes that the implementation of these recommendations will serve to best protect
human health and the environment.
