If you want a fully intrusive survey (Type 3) this would find this for you, A type 2 would not batter holes in your walls floors and ceilings, they would only take a representative (discreet) sample,and assume or not that it contains ACM's using their experience or knowledge of the building.

Dont't knock the surveyor, batter the client who will not pay for the more expoensive type 3 or puts restrictions on the amount of samples the surveying company can take.

It is always best in this situation that the client and surveyor meet on site and you could do a type 2 on that wall and a type 3 here etc etc
(Limited type 3)

Again don`t knock the surveyor. Working practise concerning the mixing & application of textured coatings in years past i believe was not consistent. Also the amount of asbestos (generic) added to a product also may not have been consistent. So representative or directed sampling on ceilings and walls may not always be accurate in my opinion due to the application.

Then you have the liklihood that you may have textured coatings applied to various ACMs for example boards for fire protection on stairwells. So again tradesmen may not always know what is behind the texured coating. For example drilling into a textured coating during maintenance, the textured coating may not be a positive but the product behind it may be and this product will not be picked up on during a type two unless you have access to it as a surface material. All procedures.

Re: Comments concerning textured coatings not pipe lagging!. Making a presumtion concerning what is under a surface material for example texture coatings is very important not just for the surveyor but all involved, (Speaking from experience as a surveyor in years past and working in the construction industry when ACM`s were still being used). The recording of a survey is so important and experience at survey level and knowledge of where ACM`s were used is so important.I have came across similar issues in the past. PROCEDURES, Recording and reporting concerning limitations must be spot on.

HSG 248 baloney, MDHS 100 is the surveyors bible, dont get me wrong here people, although I have a P402 and work for an asi company there are lapses on both sides the surveying and the client.

The most important thing is a pre site meeting and this very very very rarely happens.

No access, locked doors, no plans, so surveyor and client drawings dont match, wrong survey type needed type 3 asked for type 2 and vice versa. etc etc etc
