Ken, Isn't it the information already provided for in the hydraulic calculations? I'm only asking because there is an AHJ that has asked for an isometric drawing be provided on the plans showing "the relative elevations of sprinklers, junction points, and supply or reference points. See NFPA 13-2013 Section 23.1.3 (37)".
There is no isometric requirement in NFPA 13 that I'm aware of. It seems like this is the information in the calculations that would correspond to the hydraulic node points on the drawing.

Just my opinion, Ken Wagoner, SET Parsley Consulting 350 West 9th Avenue, Suite 206 Escondido, California 92025 Phone 760-745-6181 Visit the website <http://www.parsleyconsulting.com/> On 01/09/2020 1:41 PM, Bob Knight via Sprinklerforum wrote: >From NFPA 13 (2013 ED), 23.1.3 (37) Relative elevations of sprinklers, junction points, and supply or reference points. This is probably an obvious question, but not to me. What is this asking for?
