Hazardous Materials Survey
Demolition, Design and Construction of a New Airport Facility
As a joint venture, The Horrell Group and Self+Tucker, two architecture firms in Memphis, Tennessee, were contracted by the Memphis Shelby County Airport Authority to work on a new airfield maintenance and operations support facility. The two firms were tasked with preparing demolition specifications, as well as design documents, for the new facility. In order to complete the demolition specifications, the two firms teamed with Tioga to assess hazardous materials in the building.
Before demolition of the old building began, Tioga’s team surveyed the location for asbestos, lead-based paint and other hazardous materials, such as mercury thermostats, fluorescent light bulbs and refrigerants. The team then determined which materials required immediate disposal. The inspectors included Maggie Strom, project manager; Phillip Gardner and Aaron Bennett, asbestos inspectors; Caleb Chapman, lead-based paint inspector; and Eric Davis, hazardous material inspector.
For the asbestos testing, Tioga identified, differentiated and sampled various areas based on color, texture and apparent installation date. The team followed all federal regulation requirements during the inspection. The asbestos survey was performed in accordance with procedures of the Asbestos National Emission Standard for Hazardous Air Pollutants (NESHAP), the Asbestos Hazard Emergency Response Act (AHERA) and the American Society for Testing Materials (ASTM).
Tioga determined the lead content of the building’s surfaces by using a Niton 300A XLP X-Ray Fluorescence lead-based paint analyzer, which achieves instant readouts and decreases the chance of destructive samples.
After inspection, Tioga prepared a comprehensive report summarizing the findings of the hazardous materials survey. The report provided tables, site plans and photographic logs to document the amount and location of hazardous materials found in the building. The team also prepared a hazardous material and asbestos abatement specification section for incorporation into The Horrell Group/Self+Tucker’s demolition design package.
