This type of survey is used to locate and describe, as far as reasonably practicable, all ACMS in the building and may involve destructive inspection, as necessary, to gain access to all areas, including those that may be difficult to reach.

A full sampling programme is undertaken to identify possible ACMs and estimates of the volume and surface areas of ACMs made.

The survey is designed to be used as a basis for tendering the removal of ACMs from the building prior to demolition or major refurbishment. Therefore, the survey does not assess the condition of the asbestos, other than to note areas of damage or where additional asbestos debris may be expected to be present.

From the information taken from the Asbestos Survey a priority would be given to the action required for any asbestos containing materials found.

The purpose and procedures used in this survey are the same as for Type 1, except that representative samples and collected and analysed for the presence of asbestos.

Samples from each type of suspect ACM found are collected and analysed to confirm or refute the surveyor’s judgement.

If the material sampled is found to contain asbestos other similar homogeneous materials used in the same way in the building can be strongly presumed to contain asbestos.

Less homogeneous materials will require a greater number of samples.

The number should be sufficient for the surveyor to make an assessment of whether asbestos is or is not present.

Sampling may take place simultaneously with the survey, or as in the case of some larger surveys, can be carried out as a separate exercise, after the Type 1 survey is completed.

The purpose of this survey is to locate, as far as reasonably practicable, the presence and extent of any suspect Asbestos Containing Materials (ACMs) in the building and assess their condition.

This survey essentially defers the need to sample and analyse for asbestos (or its absence) until a later time (e.g. prior to demolition or major refurbishment).

The duty holder bears potential additional costs of management for some non-asbestos-containing materials.

All areas should be accessed and inspected as far as reasonably practicable (e.g. above false ceilings and inside risers, service ducts, lift shafts, etc.) or must be presumed to contain asbestos.

Any materials that can reasonably be expected to contain asbestos must be presumed to contain asbestos. There should be a strong presumption that it does.

All materials that are presumed to contain asbestos must be assessed.
