Hi All, We are having a second level mezzanine floor built (additional level on a current mezzanine floor). It will need to be reported to the HSE on an F10 form. I have been asked to be the CDM co-ordinator which is making me feel uneasy. I have a NEBOSH General cert (Tech IOSH) with very limited experinece in CDM & construction in general. The big question is how do you clealry define who is competent to be a CDM coordinator and what are peoples opinoins on whether I would be classed as competent. (Its obviously cheaper for me to do it than pay for someone from outisde the organisation). The new mezzanine floor will be approx. 4000 sq feet. All comments welcome.

Actually before reading appendix 4 I'd read paragraphs 84 to 108 - you need to know what the CDM-C needs to do before you can decide whether you can demonstrate competence to do it. In particular paragraph 90 says what you would have to do - and I wonder in particular if someone who has "very limited experience in CDM & construction in general" will be in a position to identify if there are gaps in pre-construction information, advise if the arrangements for managing the works are suitable.

Azza, The burning question at the back of my mind is why have you been asked to undertake this specific statutory role rather than the structural engineer? To be honest, there should be plenty of other people on this project amongst the CDM team with the necessary competence to undertake the CDM-C role. The final question which you should be asking yourself, if this structure came crashing down, would you have the necessary professional indemnity to cover you? Even as a Chartered Builder, Chartered Fellow of IOSH and as a Registered Member of APS, based upon what you have already described, this may even be a project which I would question taking on!
