VA Mather Survey Report Building 650 2nd floor.pdf

This is a Hazardous Materials Survey Report for VA Mather Building 650, conducted by PBS Engineering + Environmental in June 2009. The survey focused on identifying asbestos-containing materials (ACM) in the building's second and third floors, following OSHA regulations for pre-renovation hazardous materials inspection.

Key findings include the presence of multiple asbestos-containing materials across various locations, such as fireproofing debris, residual floor mastic, hard fittings/fiberglass on domestic water lines, and sink undercoating. The survey documented approximately 40,000 square feet of residual floor mastic, 500 hard fittings, and 10 sink undercoatings containing asbestos. Some asbestos-containing materials were found in concealed areas like wall cavities, ceiling spaces, and mechanical chases. The report also noted the building had undergone a substantial renovation within recent years, with previous asbestos abatement projects documented. Laboratory analysis revealed chrysotile asbestos in several material samples, with percentages ranging from 2% to 8% in various materials.
