Asbestos and Hazardous Material Identification

Asbestos and hazardous material identification surveys determine whether asbestos-containing materials (ACMs) or other hazardous substances are present within a structure. Inspections and material sampling help identify potential risks before refurbishment, maintenance, or demolition works begin.

The Process

A trained surveyor inspects the structure to locate materials that may contain asbestos or other hazardous substances. Suspect materials are safely sampled and analysed in a laboratory, with findings recorded in a report detailing their location, type, and condition.

The Reason

Identifying hazardous materials in advance protects workers and building occupants from exposure to harmful substances. It also allows appropriate control measures to be planned before intrusive construction activities take place.

The Application

These surveys are commonly carried out before refurbishment, demolition, or major maintenance works. The results help project teams plan safe removal, management, or mitigation of hazardous materials within a structure.
