Asbestos Inspections – Major Commercial Retail Property
The project consisted of a complete building inspection to identify suspected (Asbestos Containing Building Materials) that exist within the building; the location that each material was used and the approximate quantities of each material prior to demolition. Each suspect material identified during the survey was sampled and analyzed in accordance with 40 CFR, Part 763 Subpart E, Toxic Substance Control Act to determine the asbestos content. When possible the inspection also quantified the total volume of suspected ACBMs.
Each suspect ACBM was physically assessed by the inspectors to determine if the material was friable or non-friable. Friable materials are defined as materials that when dry may be crumbled or reduced to powder using hand pressure and thus release asbestos fibers. Samples of both friable and non-friable ACBMs were collected for laboratory analysis. Typical building materials that may contain asbestos include drywall, floor tiles, roofing felt and shingles, ceiling tiles, insulation, pipe insulation, and duct insulation.
The property consisted of two single story commercial structures. The first was approximately 260,000 square foot building with mezzanine spaces which include various office space, the main retail floor, separate retail spaces, bakery, deli, meat counters, coolers, freezers, mechanical rooms, restrooms, storage areas, shipping and receiving areas, below grade tunnel and a penthouse. The second building consisted of a 1,590 square foot gas station/convenience store structure. The buildings were occupied at the time of the survey.
Each sample of suspect ACBM collected was analyzed for asbestos content using polarized light microscopy (PLM) by a NVLAP (National Voluntary Laboratory Accreditation Program) and NIST accredited laboratory in accordance with 40 CFR Ch. I (1-1-87 Edition) Part 763, Subpart F, Appendix A, pp. 293-299. Asbestos containing materials are defined as materials that contain greater that one percent (>1%) asbestos.
