In my opinion, move on. You are right. It is fire control, not fire suppression. 24" for standard spray sprinklers is the way I understand the column rule.

Due to over head duct obstructions, we had some sprinklers located about 30" away from columns. the next sprinkler was on the other side of the column, 14'-0" away from the first. The fire inspector noted that we would need to add sprinklers on the other side of the column since we couldn't meet the 3 times rule, and if we did, it would still be too far from the other sprinkler that was 11'-6" away from the side of the column. I mentioned it to him and his boss that the 8.6.5.2.1.3 rule was up to a maximum of 24" away from the column, at that point the column was no longer an obstruction, and NFPA considered this adequate coverage. He initially agreed with me yesterday, but we were shot down for a C.O. today because we didn't add the sprinklers on the opposite side of the column. Normally, I would have argued the point, but the GC just want's his CO, so he's paying for the heads. Needless to say, I now look like I don't know what i'm talking about in the eyes of the owners rep and contractor. Have I had 8.6.5.2.1.3 wrong all these years? I always thought that 24" away meant no problem, move on to the next.
