Posted By AHS Quite often Clients disinstruct the designer before the project starts and either assume the duties themselves or get the Principle Contractor to Design/Build. The question is under those circumstances should the initial designers now disinstructed be placed on the F10 aswell.

Posted By Liz Bennett The F10 is to provide information to the HSE about a project. I would recommend that if significant design has been done by some who are no longer engaged then their design decisions will have an impact on the choices others are free to make and they should be included. Perhaps put them in the end section that relates to others about whom HSE need to know. If the matter is one for enforcement then HSE will find out soon enough about who else is involved. Finally, why not tell HSE?!

Posted By Ron Hunter A key requirement of CDM is early Notification of the Project, and Schedule 1 of the Regs requires that the name and address of any designer already engaged be included. I would not suggest that you need re-notify where there is change or addition of Designer as this could be quite onerous. There are any number of "designers" involved in complex Projects, across various disciplines and specialisms, and I do not believe that the F10 was intended as a means to identify them all -that would be more a function of the pre-construction Information pack. I am slightly puzzled by the concept of a Designer being decommissioned "before the Project begins". The Project surely "begins" with a Design, and that design is usually settled before the appointment of (e.g.) the Principal Contractor?
