The CIC show their competence however, as they have done with the CSCS question. The cross referencing to asbestos falls flat on its face as little guidance is provided on what is required and the information is out of date.

BS 6187 is a good starting point along with the associated guidance notes. If asbestos is present check out the HSE website relating to what can and cannot be done without notification and employment of a licensed contractor. You will need to have or commission a type three survey before any demoliton work is carried out. CDM will apply only if the criteria for an F10 notification is met and that will depend on the size of the job.
BS 6187 only really makes sense if you're experienced in demolition though but I often have CDM coordinators (planning supervisors as they were previously) use it as a template for making sure the basics are in place.
If you have any specifics you need answering drop me an e-mail. I'm a Contract Manager for a demolition contrcator.

Peter

Please also be aware that the quality of some type 3 surveys leave much to be desired and I have seen those that are essentially type 2 at type 3 price.
I have also seen a type 2 presumptive survey today by a well known major where no samples were taken and the results state
Presumed chrysotile
Presumed Amosite
When the stated presumption must always be Crocidolite.
Care has to be taken in all information.

CDM applies to all construction projects, with specific additional 'arrangements' for notifiable work.

Type 2 presumptive sounds a bit like a Type 1 to me - is it a 'typo' - if not it calls the whole thing into question.

CDM will apply and not forgetting the section 80 notification also which notifys the local authority of the proposed demolition.

Wish it was and then one could almost make sense of it. What really troubles me is that a very well known name has produced this report and it certainly is not a typo. You then find that they think they can presume anything but crocidolite!!
It is companies like this that give the asbestos surveying sector a bad name and pose people such as myself with a problem explaining to clients that it is a virtual waste of money.
The whole point I think I am trying to make is that asbestos surveys are a closely regulated sector and they "round the corners out" so to speak - so what is one to make of other contaminant surveys such as lead, solvents etc etc. I really advise all contractors and clients that such surveys now are only indicative when we should be able to rely on the surveyor and their ability to undertake and record their activities accurately. After all if I have a survey report on a structure condition for purchase I would generally get a detailed quality report covering many items and telling me precisely what was and what was not looked at.

Hi Allan
Whether or not the project is notifiable, hence requiring a CDM Co-ordinator and Principal Contractor, any demolition project requires a "method statement" by whatever title.
Demolition or dismantling
29.—(1) The demolition or dismantling of a structure, or part of a structure, shall be planned and
carried out in such a manner as to prevent danger or, where it is not practicable to prevent it, to
reduce danger to as low a level as is reasonably practicable.
(2) The arrangements for carrying out such demolition or dismantling shall be recorded in
writing before the demolition or dismantling work begins.
Regards, Peter

You're quite right to be concerned about a leading player in the field producing inconsistent/inconclusive/confusing advice - the report type is totally anomalous and probably meaningless (??). (I would be interested to learn the identity of the publisher, just out of professional curiosity - not for the sake of tittle- tattle that isn't useful to anyone).
As with any field of expertise, there is a variation in quality, which hopefully things like UKAS accreditation or other QA systems should iron out. (In my experience biggest or most well known or most highly qualified doesn't always indicate 'best'. During the 'boom' years for asbestos surveying, virtually anyone was being dragged off the streets to become a surveyor - armed with a P402 of course and figuratively speaking!).
Incidentally, have you brought your concerns regarding the report to the attention of the survey company? I'm sure they would welcome the opportunity to rectify the issues you raise. (You may have guessed I was formerly involved in this type of activity).
I agree you should be able to rely on the veracity of a report from competent organisations, especially when findings can have huge impact on H & S and £/p further down the line.
My own view on the 'presumption' bit is that you can indicate fibre type for certain materials, say fire blankets, AC sheeting and AIB (as long as the surveyor has experience of what these materials look like with/without crocidolite), but where there is residual uncertainty, to then presume crocidolite (as per MDHS100 Para 36 and Table 1)

Presumption becomes set in stone for the client as "definitely is" and what happens then when work is to commence which may interfere with the material.
I am very wary aboput any presumptions on content as i have known it fall flat many times. Grey cement corrugated sheet for example - presume chrysotile? Sample showed 8% crocidolite!!! Same with blankets some years ago.

It's still possible to be confident with the necessary past - those who only have experience of surveys are unlikely to be in this position, but if you've undertaken enough bulk analysis......
Cheers
