Well, it's all one building unless it's not. However, generally such a complex would be built without separations between the buildings and parking that would classify the complex as three separate buildings. Without complicating the issue, and just to be sure, it's probably prudent to verify that this project has a single address. If it doesn't, the follow-up question is are these separate buildings by code? Thereafter, if the answer is yes then I would ask the responding fire agency if they want a single water supply or separate ones by address. It is accurate to say that if it's classified as a single building then it should be an integrated automatic water supply that satisfies the code requirements for a high-rise building. And one that is sized for the gross number of standpipes, not just the two that might be in the 11-story component.
The preceding information is my opinion only.

On another note, I’m not sure how a 9 story building isn’t a high rise unless it is less than 8’-4” between floors. Nick Maneen, SET c 704.791.7789 From: Sprinklerforum [mailto:[email protected]] On Behalf Of James Litvak Sent: Thursday, June 28, 2018 1:44 PM To: [email protected] Subject: High Rise and Non-High Rise Standpipes I've got a building that is two towers with a parking garage in between. 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)?
