I recently attended HROC (High Rise Operations Conference) in Pensacola on the invitation of two NFPA 14 committee members who are active fire service. It’s a fire service-only event and I was the only civilian in attendance – to say that I learned a lot is a great understatement as it was possibly the most informative professional event I’ve ever attended. Also, I got an earful from firefighters, captains and chiefs who regularly use standpipes in mid- and high-rise buildings.
The information in that card is VERY important to the engineer on the first due pumper. In fact, based on hearing about this from at least 8 or 9 different attendees at HROC, I’m going to introduce a committee input that would require that the inlet and outlet flow and pressure metrics be permanently labeled at each hose connection equipped with a pressure reducer. (On a side note, there is so much energy AGAINST factory-set PRV hose valves, you can’t imagine. Down to the last man and woman, firefighters want infinitely adjustable PRVs such as the Elkhart URFA and the new Zurn 5000 series.) Placing the basis of design on the documents is the first step and it enables enforcing the placement of the required signage at the inlet(s) and this information can literally shorten time-to-water by as much as 6-7 minutes by allowing the engineer to start pumping much closer to the target at the tip, regardless of whether the system has PRVs or not. I also agree with JD that format isn’t critical.

We show the information NFPA 14 requires. Format is not critical but the information must be shown. Thanks, John John August Denhardt, P.E.

The contractor indicated that SprinkCAD provide a standardized hydraulic result. That seems like a lame response. I'm sure another format or even text information could be provided rather than using NFPA 13's Hydraulic Calculation results for the design area. What do you provide the required information from 6.8?
