Visually classify the samples in accordance with the Unified Soil Classification System (USCS) soil classification system.
Conduct laboratory testing on select soil samples to confirm the visual classification and estimate engineering properties.
Prepare a geotechnical report signed and sealed by a professional geotechnical engineer that summarizes the course of study pursued, the field data generated, laboratory test results, subsurface conditions encountered and our engineering recommendations in accordance with the scope of services presented herein.
Tierra understands a National Emissions Standard for Hazardous Air Pollutants (NESHAP) Asbestos Survey and screening for Lead-Based Paint have been requested prior to the demolition of two structures: 1) the McClure Auditorium building, and 2) the canopy adjacent to the building.
An on-site survey of exposed and accessible building materials within the proposed work areas will be conducted by an EPA AHERA accredited asbestos building inspector. The inspector will list suspect Asbestos Containing Materials (ACMs) and give a detailed description of their locations. If provided, Tierra will review past reports, specifications, drawings, and other documents provided by the Client that would assist in identifying the suspect materials for this project. Samples will be collected according to EPA guidelines, which dictate the number and location of samples to be collected. Tierra will attempt to sample damaged areas and areas that are least visible. The following is a listing of the typical suspect ACMs that may be sampled:
Surfacing Thermal System Insulation (TSI) Miscellaneous Roofing Materials
Fireproofing Pipe Insulation Ceiling Tiles Felt
Acoustical Plaster Boiler/tank Insulation Acoustic Tiles Shingles/Roll
Hardwall Plaster Breeching Insulation Blown-in Insulation Fiberboard
Stucco Ductwork Insulation Floor Tile/Mastic Tar paper
Cementitious Panels Foil Mastic Linoleum Mastic/tar/pitch
Textured Coatings Duct Mastic Gypsum wallboard Soil stacks
Concrete Attic/Wall Insulation (vermiculite, mineral wool, etc.) Cement Pipes Flashing
All building material samples will be analyzed using Polarized Light Microscopy (PLM) according to current EPA regulations. If sampled materials are identified to contain less than 10% asbestos the point count method as specified by EPA NESHAP regulations can be performed at the Client's request.
The inspector will list the type of materials identified and determine the quantity of each material. Some areas may be inaccessible and not all materials can be fully quantified. For those areas,
