Type
3: Pre-Demolition/Refurbishment Survey - full access, sampling
and identification
A Type 3 Survey is the most comprehensive and can include destructive
inspection techniques, wherein extensive samples are taken from
all areas including those which are reasonably inaccessible.
The samples are analysed in a laboratory to detect the presence
of any ACM’s and the risks assessed based upon the results
of sample analysis. However, it should be noted that in some
cases ACM’s may be concealed within the fabric of a building
which can only be positively identified once demolition has
actually begun. Type 3 surveys will only be undertaken in unoccupied
buildings. This type of survey is designed to be used as a basis
for tendering the removal of ACM’s (Asbestos Containing
Materials) prior to demolition or major refurbishment. It should
be noted that a Type 3 survey will not necessarily assess the
condition of asbestos materials identified, other than to note
areas of damage where additional debris may be detected. |
