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
