Demolition Asbestos Survey

Under the control of Asbestos Regulations 2012, the old “Type 3” asbestos survey was renamed “Demolition Asbestos Survey” and as its name implied, it is required when a building (or part of a building) is to be demolished.

This is a highly intrusive and destructive survey, as the aim is to protect demolition workers from being accidentally exposed to hidden asbestos.

In older buildings, asbestos was often used during construction as packing material, boarding and insulation which over time and various refits or ownership changes, became hidden, as it was encapsulated behind other materials and then forgotten.

Such materials would not necessarily be identified in a normal management asbestos survey, so during a demolition asbestos survey, the surveyor will be keen to open up any enclosed partitions, voids, etc.

Particular attention will be paid to ceilings, ceiling voids, pipework, cellars and other underground void areas.

In short, everything that could possibly contain asbestos will be sampled, quite possibly multiple times to ensure that risks to demolition workers are minimised.

Of course, there may be occasions where not all materials can be identified during a survey and therefore, most surveyors will be happy to return to site during the soft-strip and other stages of the demolition.

An example we see often is where asbestos containing materials were buried under the building footings, which cannot usually be inspected while the building is still standing!

The demolition asbestos survey is the most comprehensive and therefore the most expensive type, but costs can be kept to a minimum if only part of the building is being demolished, as the surevy can be restricted to those areas.
