What happens if I change principal contractor part-way through?

Just thinking through options - we've had a principal contractor from the start, whilst some specialist contractors have come in for different elements of the build, the PC has remained constant. If we get to a point where we look to finish the internal fit-out ourselves, how does the PC role and (specifically the Building Control Principal Contractor sign-off work?

 

I'm aware that the PC definition for CDM and Building control uses the same term 'Principal Contractor', but has a different definition and responsibilities. My main focus is related to the PC Building Control sign-off, though I am interested in the CDM aspects too.

 

Grateful for your experience & thoughts. I'm trying to make sure I have a clear contingency plan in case we a re finishing the build and fit-out by ourselves.

Does anyone have any experience of this, or advice please?

You assume the role of PC. Just update your documentation etc.

Do you get the previous PC to sign off for the work up to that point? If I brought in another PC, and they were expected by Bldg Ctrl to sign at the completion, they would surely not be expected to sign for the earlier stages of work? (or if they are, how would this be managed? have you had to do this, or seen it done?)

I fired two main contractors and ultimately took it over. 

 

It's not that big a deal. 

 

Check in with BC to see where they are at and what stage they next want to inspect.
