Office system not designed with flex heads? Depends. Was there a huge buffer in original design? But if original had 1” sch 40 drops, that are changing to flex? Expect to provide them. When they created the generous coefficient for quick response and low ceilings, and combined with EC heads you could get down to six heads in offices. I remember calling the then incumbent NFPA staff P.E. for pamphlet 13. I asked about very minor T/I’s. The kind that were below our permit threshold, ‘field review, field inspect”. The answer I received was that all jobs in hydraulically designed systems require supporting calc’s. I felt it was more of a jD answer than a PE answer.
