Asbestos Surveys

What Is "Asbestos Surveys?"

Texas Senate Bill 509, passed in 2001, requires municipalities to verify that an asbestos survey has been performed prior to issuing renovation and demolition permits for public or commercial buildings. Residential properties being renovated for non-commercial purposes are exempt from this law. The surveys must be performed by an individual licensed by the Texas Department of State Health Services to perform asbestos inspections. An asbestos survey checks to see if asbestos is in building material prior to renovation or demolition. An inspector takes a small piece of suspect building material to be analyzed. The sample must include all the layers of the building material (example: Drywall/Joint Compound/Texture of a wall). The sampling strategy must be in general accordance with Texas Asbestos Health Protection Act (TAHPA) Texas Civil Statutes, Article 4477-3a, as amended and EPA AHERA sampling protocol. A minimum of three (3) samples will be collected of each identified suspected asbestos-containing homogeneous (similarity of color, texture, and type) material. The samples are analyzed using Polarized Light Microscopy (PLM) in conjunction with dispersion staining techniques by a lab that is NVLAP certified and Department of State Health Services licensed.


Asbestos Survey/Inspection Process

  • Receive building information
  • Provide an estimate of cost based on building information and how quickly the final report is needed
  • Have a licensed inspector perform the asbestos survey. Our inspectors are as discrete as possible in collecting building material samples.
  • Three samples must be taken of each homogeneous (similarity of color, texture, and type) building material that will be disturbed by upcoming renovation or demolition activities
  • The samples are taken to a third party lab for Polarized Light Microscopy (PLM) The lab analysis turn around time is 1-3 days. Faster turn around is available by request.
  • Once the PLM lab report is received from the lab, Precision creates a comprehensive report and emails it to the client
  • If asbestos is found during the inspection, the client can decide to leave the material in place and not disturb it.
  • If the client wants to remove the material that contains asbestos they must hire a licensed abatement contractor and asbestos consultant company.


Asbestos Abatement Process

  • If a building owner wants asbestos materials removed, they must hire an abatement contractor and an asbestos consulting company.
  • Once the owner has selected a contractor, as an asbestos consultant, we provide them with project specifications to follow during the removal process.
  • Precision will also perform air monitoring before, during and after removal.
  • After removal of asbestos containing materials, Precision performs final clearance testing before the containment is taken down. Once the final clearance samples pass, the contractor tears down the containment.
