Yes...same maximum...just do 500+500+250 and you are good to go.
You can verify with the standpipe guru, Steve L, but I think he will
agree that it would be 500/500/250 for your scenario.

No, it IS 90k / floor... still the same _maximum_ requirement of 1,250

Oh..I thought he meant 90k sq ft per floor.
Would be hard to get 6 standpipes in what I assume is minimum 4 story
building. That would be 22.5k sq ft per floor. I can't see having 6
standpipes on a floor area that small...but it is possible.

Travis,
His building is 90k total, not per floor. I don't think what you
just posted applies.

90k sq ft changes things...
For buildings over 80k sq ft, you do 500+500+250
*7.10.1.1.3 *The minimum flow rate for additional standpipes shall
be 250 gpm (946 L/min) per standpipe for buildings with floor areas
that do not exceed 80,000 ft2 (7432 m2) per floor. For buildings
that exceed 80,000 ft2 (7432 m2) per floor, the minimum flow rate
for the additional standpipes shall be
500 gpm (1893 L/min) for the second standpipe and 250 gpm
(946 L/min) for the third standpipe if the additional flow is
required for an unsprinklered building.

I really don't know if it should be I or III. No sprinklers and -
oh, 90,000 sq ft. Current code. I'm thinking 500 + 250 until 1,250
but I can't see that in 14 anymore. Old age setting in again?
Thanks for the help.

Hello Forum --
I have a building with a dry, manual standpipe fed from an FDC.
There are six standpipes with 2½" valves.
Can someone break down the NFPA flow requirement, Barney-style for me?
I'm thinking 500 gpm first and 250 gpm each additional. My question is
how many additional?
I guess they should put more pictures in the code!
thanks, Vince
