The end result was 21 sprinklers in a space no larger than 1200 square feet. The submitter put a note on the plan saying that they were taking the exception of only counting sprinklers in separate fire areas, his badly flawed premise being that the non-rated walls forming the little rooms represented a fire area separation of sorts. The other was a retail tenant Improvement in an existing Ordinary Hazard shell building where outlets were spaced at 120 square feet and originally designed for K5.6 sprinklers. The TI utilized extended coverage at 20 x 20. The submitter's reasoning was it was like for like because the hazard didn't change and there were fewer sprinklers. Like everything else, we in the sprinkler community need to take ownership of what is still a low standard of care in our industry. On the AHJ side of the counter, we hope that common sense will prevail.

As far as the PE seal, that is jurisdiction specific. We have PE on staff and seal in jurisdictions that require. This has just been something that has been popping up more and more. It was very rare in the past. We maybe calculated 1:100. Now I am seeing 3:5 requiring it for the jurisdictions I deal with.

More of the rule and not the exception. I don't see anything to the extreme you are talking about. I did have one recently where the existing sprinklers were installed on flex drops and we have to move 5 sprinklers one pad over. The engineer stated if we used flex drops (even the existing ones), the system had to calculated. However, if we removed the flex and installed hard pipe, no calcs we're required.

Just your run of the mill add/relocate. I am seeing it come up more and more. I am seeing it in situations where it is mostly relocates and no additions anywhere near the design areas. I have one now where the AHJ rejected for no calculations where the shell was OH2 and the new space is residential lofts. This particular AHJ wants us to show all piping on portions of the floor where no work is being done. They are also requiring us to submit plans for the two floors below our space that have no work being done. Is anyone else seeing stuff like this?
