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

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.

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?
