First off it is NEVER my call to decide whether a system is to be designed per NFPA #13 OR 13R.
That call is 100% the call of the project registered architect of record and nobody else.
So I am looking at a two story project where there three offices with a residential area designed per NFPA #13.
But the second floor is all residential and with the system designed per NFPA #13R.
There's an inside stairway that does not appear to have any rated doors or doors at all.
As I understand it the first and second floor has to be rated... maybe one hour but I am not sure and will NEVER make that decision.
I've done these sort of jobs before but I have always got what the design should be from the architect of record IN WRITING.
If I have it in writing, from the registered architect of record, I view it as my get out of jail free card should be be wrong.
Oh, I once had a small single story motel that 99% of sprinkler designers would have been sure was a 13R system but because the means of egress though the back didn't fit right it was deemed to require a full 13 system.
That said I want it in writing either on the signed and sealed architectural drawings or in writing from the architect of record.
Your experience on this?
