| Type 3 Survey
The “Type 3 Survey" is probably
the most important and yet probably the least used. A fully
intrusive survey, which the law requires before any major
refurbishment or demolition of buildings can be carried out,
means that the surveyor will actively search out asbestos
within the very fabric of the building – no area should
be left unchecked and all suspected ACM’s will be sampled
and reported on. Drain runs, riser cupboards, lift shafts
etc. would be examined to ensure there is no chance of unexpected
exposure by workmen involved in the refurbishment/demolition
project.
Type 3 : Full access sampling and
identification survey (pre-demolition/major refurbishment
surveys)
This type of survey is used to locate and
describe, as far as reasonable 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. This survey is designed to be used as a basis
for tendering the removal of ACMs from the building prior
to demolition or major refurbishment, so 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.
16. Although different types of survey can
be specified and used depending on the circumstances, it is
important that the building owner, employer and the surveyor
know exactly what type of survey is to be carried out, what
the specifications for each type are, and in which areas they
are to be used. It is recommended that the type of survey
used conforms to a standard (eg this MDHS), otherwise interpretation
of the survey reports will be difficult and the management
plan produced may not adequately minimise the risks involved.
It is possible that at larger premises a mixture of survey
types will be appropriate - eg a boiler house due for demolition
will require a Type 3 pre-demolition survey, while offices
at the site may only have a Type 1 presumptive survey. Similarly,
a system-built property may start with several Type 2 surveys,
but other similar premises may be evaluated using a Type 1
survey. Therefore it is important that there is a clear statement
and record of the type of surveys that are to be carried out,
including that reasons for type selected, where they are to
be carried out, and an estimate of the number of samples to
be collected.
Many of our clients have commissioned PVsurveys to carry out
a Type 3 Survey on their premises.
