Posted By Peter MacDonald Hi Dennis All demolition work subject to CDM 2007. Should be a Pre-tender health and safety plan available. A demolition phase Health and Safety Plan should be in place. A risk assessment and method statement should be produced with ref to and satisfying the requirements for BS 6187 code of practice for demolition. Any lifting studies should be carried out by an appointed person for lifting and a lifting supervisor and slinger/banksman must be on site during the lifts. Contractor appointed should be competent.Trained competent men with a supervisor on site. CDM Coordinator should ensure this. Too many risk and hazards to mention here and I've no real info on the job but obviously working at height, trained competent people for the plasarc, scaffolding, MEWP or any equipment really, Segregation of public,creating a safe, controlled working space, safe access, debris spread from plas arc, flammable material in the vicinity, simultaneous operations, layered working, banksman for transport, access for slinging the load, what was in the vessel, is it still there, venting to atmosphere, handling cut sections (50mm s/s is very thick by the way, are you sure it's not mild steel). Will piecemealing it cause it to become unstable. I could go on but for fear of boring you to death, if you want I can e-mail you some risk assessments for similar work. Peter

Posted By Dennis101 Agreed there Mitch, but the stack is clad in a thin layer of aluminium and a demolition squad is being engaged to remove it.

Posted By Mitch Peter. It is a component (from the description given, a silo) which is being dismantled and re-assembled, not demolished. Mitch

Posted By Peter MacDonald Mitch In my opinion, If it's being scaffolded, cut up into peices with plasarc, lifted down in sections by crane by a demolition contractor then it would come under demolition BS6187. Therefore, although it is being dismantled, or de-constructed, re-engineered, de-commissioned etc it comes under the scope of "demolition" and therefore the CDM regs and all of what I said above. I've been involved in removing silos, tanks, reactor loops, gas holders, agitaion tanks, underground storage tanks and plenty others and in my experience unless it's being craned or skidded out whole, it has all been in accordance with BS6187 and therefore demolition. If it isn't what would you say the goverening legislation/regulations that are applicable? I'm not having a go by the way. It's difficult to question someone on a forum without sounding like you're shouting or being difficult! Regards Pete
