Hi Anderson8 If the "new" project is and extension of the existing project caused by significant additional work that will extend the time then a supplementary F10 is a requirement. However if it is a seperate project then a new F10 is required. As these projects are notifiable there should be a competant CDM Coordinator on board who should be able to answer these questions. Also please remember that the notification is only a very small part of the requirement of the CDM Regs. Hope this helps

Be careful re the term 'separate project' as the CDM regs are designed to try to make projects that are really 1 project [the proximity philosophy] stay 1 project - the breaking down of larger projects into a series of smaller projects is not really on If there is a break of 6 months between the end of one project at the same place for the same client and the start of another project then they can be seen as 2 separate projects with their own management systems abet referencing what is needed from other systems & the H&S file Where there is a gap of less that 6 months between projects the T&C's etc and even the PC etc can be different parties but the overall management system can be continuous with tweaks - we are not talking about what is being built as that can be different we are talking about the umbrella management system for all construction activities at that one location with the one client I use the proximity principal all the time [after chatting with the HSE and the EA [for SWMP jobs] - new PC's, designers etc do not like the system as they like what they see as 'neat boxes'. Success depends on the clients attitude and the tweaks mentioned can be large or small to suit the situation QA sometimes trys to get in the way however I note to all that QA is not law so it must be changed to suit the circumstances and any good QA system should be able to change as circumstances dictate
