the section to fill the area of the removed insulation and seal the insulation within
the section. Allow the mortar to adequately dry.
As each section of material is cut free and properly prepared, remove the sections
from the trench.
Prepared component sections will immediately be placed into an acceptable waste
transport vehicle. No stockpiling of removed components will be allowed outside
of a locked, secure waste transport vehicle.
D. For the removal of Non-Friable Asbestos Materials, the Contractor shall:
1.
Carefully excavate, by hand, a sufficient area around the material to perform the
abatement work. Any asbestos debris that is present or generated by these
activities will be promptly wetted and placed into Disposal Bags before
continuing with the Work.
Once excavation is complete, place one layer of 6-mil polyethylene sheeting on
side walls and bottom of trench under the ACM to be removed.
Thoroughly encapsulate Asbestos-Containing Materials with an acceptable
penetrating encapsulant per manufacturer’s guidelines.
Remove Asbestos-Containing Materials as follows:
a. Asbestos Cement Pipe (ACP), Duct or Board:
Should ACP be found in the trench, the City may elect to handle the
removal of that material depending on the availability of trained personnel
from the City Solid Waste Department. The Contractor will initially
contact the Engineer who will arrange the removal process with the City
Solid Waste Department. The Contractor shall assist by carefully
removing sections of ACP found in the trench such that 1s can removed in
whole sections to be subsequently handled by the qualified City
personnel. Should it be necessary to cut the material, a the pipe shall be
kept wet and cut material into manageable sections using HEPA-filtered
saw. The Contractor will take all necessary precautions to avoid any
breakage of the ACM. Cut ends of pipe will be immediately encapsulated.
Should City personnel be unavailable to remove the pipe, the cut sections
of pipe will be removed from the trench and immediately wrapped and
sealed in two layers of 6-mil polyethylene sheeting or placed into Disposal
Bags. Packaged waste will then be placed into acceptable waste
transportation vehicle.
Note: Whenever possible, the Contractor will limit cutting of asbestos
cement materials and dismantle materials in intact sections.
