An asbestos survey is needed to verify whether the materials present in the building contain asbestos and to outline the location and condition of asbestos-containing materials (ACM).
An asbestos survey is based on a walk-through inspection and sampling of suspect building materials for asbestos. An assessment of relative risk of exposure to airborne asbestos takes place during the survey.
Factors included in the assessment:
Type and amount of asbestos in ACM;
Friability and condition of ACM;
Accessibility to building occupants; and
The likelihood of disturbance by regular activities in the building.
