The project is using 2003 IBC and I don't see the chart or exception in
there. Is this new to 2006 IBC?

Subject: RE: Fire Flow requirements
I deal with this problem everyday here in Phoenix. Table B105.1 list the
required fire flows based on total square feet of the largest building
on a site. B105.2 Exception allows up to a 50% reduction in fire flow
for buildings sprinklered in accordance with 903. It doesn't sound like
the AHJ has allowed a reduction for sprinklers so I would first ask that
they reconsider the requirement and apply the allowed 50% reduction.
Where is the 500 ft dimension coming from? 508.5.1 Requires private
hydrants if all portions of a facility are not within 400 ft. of a
(public) hydrant on an access road so 500 ft. is pushing the envelope.
Good luck and please let me know how this ends.

Subject: Fire Flow requirements
Hello Forum,
I have a situation where a city is requiring 4800 gpm to be flowed @ a
min of 20 from all hydrants within 500 ft of the bldg. This particular
bldg has
5 hydrants on a 12" city line. I have received a flow test of 96-S 64-R
2519-GPM and set all five hydrants to flow 960 GPM. This will not
produce the requirement. We do have a pump being installed inside the
bldg.(2000 GPM / rated pressure of 60). If I pipe out from the pump room
and add hydrants around the bldg. I still cannot meet this requirement.
Has anyone run into this problem or had a similar situation? Any
suggestions?
