SIGMA inspectors have experience with conducting surveys in office buildings, apartments, schools, industrial facilities and commercial locations. Though the use of asbestos in building materials have been curtailed over the years, there still remains the possibility of finding asbestos in almost any building. SIGMA will inspect buildings identifying suspect materials that may contain asbestos. The inspector will collect bulk samples that are sent to a licensed laboratory to determine asbestos content. The survey documents all materials that were sampled; materials which contain more than 1% asbestos are deemed to be “positive” for asbestos content. The report will document locations, quantities, asbestos content, and condition of each asbestos containing material (ACM).
