AmTrust Realty Corporation: Summary of Work

AmTrust Realty is the owner/management agent for 250 Broadway and as such, has the primary responsibility for insuring that the 250 Broadway Building is safe for occupancy. Prior to reopening 250 Broadway on September 17, 2001, AmTrust followed both the New York City's Department of Citywide Administrative Services (DCAS) and Department of Environmental Protection (DEP) published procedures for reopening a building, after the disaster, in Lower Manhattan (see Attachment F for copies of those procedures). AmTrust performed the following maintenance activities prior to reopening the Building: v' Cleaned the Building's HVAC System (Air Handling Units) Cleaned the exterior vents that supply the Base Building HVAC and NYCHA supplemental HVAC Systems Replaced all filters throughout the Building's HVAC System (Note; the Building uses the highest performing particulate filters (85% to 95%) available for the System Cleaned all surfaces throughout the Building's public spaces (e.g., lobbies) and tenant areas Flushed all domestic water systems Y" Hired environmental consultants, “Glomar” and “Independent Monitoring and Analysis”, to sample for asbestos and lead. No asbestos fibers were detected within the Building. See Attachment B for analytical results. Elevated lead in dust levels was found in several of the dust samples. Again, please be aware that NYCHA used the most protective standard under HUD, 40 micrograms of lead per square foot (pg/ft^), to evaluate the risk from lead in the settled dust within the air handling units and tenant spaces. This standard is used to determine whether children may re­ enter an apartment after lead has been removed or abated. AmTrust cleaned the air handling units and NYCHA spaces until all dust sample results were below 40 pg/ft^. The Laboratory Analytical Reports for the lead in dust samples can be found in Attachment D. Please note that the New York City Department of Buildings found the building structurally sound.
