Were operable window hidden surfaces investigated? Do these surfaces still contain WTC
dust/residue, which must be cleaned prior to sealing of the windows as critical barriers?
Please provide additional information regarding these potentially contaminated surfaces.
0 4.4 ASBESTOS-CONTAINING MATERIALS
The only materials referenced within this section are interior vapor barrier and nonfriable
lintel flashing. Is the lintel flashing included within this section the same as the ACM
spandrelflashing mastic and beam flashing mastic at the loading dock entrance identified
within the asbestos summary table later in the report? Please correlate these materials
appropriately with bulk sample analysis data_ Also, no information is apparent within this
section regarding the ACM window caulking at the stair and elevator mechanical room
roofs, the ACMroof membrane on the 14'hfloor roof, or the ACMwindowframe caulking at
the first floor exterior of the building. All of these materials were identified within Report

4CMspandrelflashing removal during deconstruction was references; but no other exterior
ACM identified within the Facade Report was discussed within the summary.
5.4 ASBESTROS CONTAINING MATERIALS SURVEY
Is the vapor barrier on interior surface offacade block referenced within this section the
same as the ACM tar, paper, and fiberglass/felt materials (1'' through 15th floor) on the
perimeter walls identified within the asbestos summary table later in the report? Please
correlate these materials appropriately with bulk sample analysis data Also, no
information is apparent within this section regarding the ACM window caulking at the
elevator mechanical room roofs, the ACMroof membrane on the 14`x'floor roof, or the ACM
windowframe caulking at thefirstfloor exterior of the building. All of these materials were
identified within Report Attachment IV, Table I "Summary of Inspection Results for
Asbestos ". In addition, the results summary indicates that floor covering materials were
assumed to be ACM but nothing is included regarding the floor covering adhesives/mastics.
These materials should also be assumed and treated as ACM unless appropriate bulk
sampling and analyses adequately show the materials to be nonACM.
