I’m not sure how this plays into this, if at all.
Section 7.10 and subsections tell us how many standpipes to calc and how much water should flow through each. Annex section A.7.10.1.1 says “If a water supply system supplies more than one building OR MORE THAN ONE FIRE AREA, the total supply can be calculated based on the single building OR FIRE AREA requiring the greatest number of standpipes.” Capitalization added by moi. Since I’m not a IBC kind of guy, how do we define a “fire area”?

This is a question for the Architect and/or the Building Official, not the FM. The FM may not know, particularly if they were not involved in the structural review/permitting process. Or they may know, and it is in fact one building, a high-rise.

If what they are asking for does not strictly follow the code, you should be able to ask for a change order. I will quote one of my preferred sources of info on standpipes - Mr. Señor Steve Leyton: “the standpipe system is exclusively for the use of the fire department, so give them what they ask for” ** I will also give you one of my favorite quotes from one of my very favorite sources - [me] : “good luck getting the city council to override a fire marshal who says he needs this for the safety of his fire crews and the people in the building” Matt **I realize Señor Leyton already made a very good comment. And I hope it goes without saying that my opinion of Steve’s opinion could not possibly hope to have any authority or relation to any of the NFPA work that Steve does.

One tower is 11 floors and is a high rise, with two standpipes. The other tower is 9 floors and isn't a high rise, with three standpipes. The AHJ has said that because the towers and garage are all connected, the tower that isn't a high rise is considered a high rise with respect to standpipe calculations. I had originally considered my calc to be 750 gpm for the two standpipes in the high rise, them being automatic wet, and 1000 gpm for the three in the non-high rise, them being manual wet. Does it make sense that the AHJ has said it is one building with 5 standpipes, and to do a 1000 gpm calc with the two standpipes in the high rise and one in the non-high rise (the fire pump is in the non-high rise)?
