Posted By Dave Wilson There should only be one Principle Contractor on site at any one time who is in overall charge, this can change as the work progresses. eg demo contractor and then taken over by builder who becomes PC

Posted By ken mosley Emma, There should be one CDM co-ordinator and one Principal Contractor for one project at any one time. The CDMC should notify the HSE (usually by F10) asap after being appointed. At that time if the Client has not appointed a PC then additional notification is required when the PC is appointed. Similarly, if the appointments are changed as the work progresses, then further notification to the HSE is required. The CDMC must make it clear that updated information relates to an earlier notification. Your posting is not clear, in so far as it seems to refer to two projects?. Ken
