John,
At least half of my clients require a separate ceiling plan. I don't know
of anything in the code but it generally makes the prints much cleaner for

Todd,
Could you not use the Room Design method for your calcs? That should

I understand that it would be a good idea for the same reasons it is
required on a standpipe but is it actually a requirement?

Brian,
Apparently the person in
Okay. Let's not get another one started today! He said "unless omission of
sprinklers is permitted".
I still can't picture what Bob has described. From what I see (at least in
my mind), it looks to me like the void would not require sprinklers.

Another problem with going AF is now we have to use Darcy Weisbach for
calculations which then opens an additional can of worms.
