Surveying and Sampling Strategies for Asbestos in Buildings P402

Asbestos surveyors play an important role in ensuring that building premises are safe for normal occupational use.

They also play a crucial role during refurbishment and demolition works to identify the asbestos within the scope of the proposed works, for it to be removed safely.
