Good morning everyone,
Thank you all for your VERY helpful comments on this subject. Again, that is why I view this forum as such a valuable resource. And while the discussion wandered a little, it was VERY clear to me early on that this was a much more complicated situation than I was capable of handling. But I was able to facilitate the owner making contact with a local consulting engineering firm and hopefully I will have a better defined design criteria soon. (Thanks to all who offered, but Ohio can be unique to deal with and local expertise is required.) The owner in this case wants to do the right thing, he was just given some bad advice early on and is scrambling now to get “above the curve” on the project. Again, thanks to all!

I know in our state it is very clear what the definition and function of engineering is as compared to the layout of systems to be completed by the contractor. You would think this would be a given but it is not. There are many times when owners feel they can eliminate engineering costs by just letting the contractor do it all. If a contractor pushes back on that concept, the owner will find someone else who will be happy to oblige. When you have someone who is not qualified to perform the actual engineering work you end up with a situation like I saw last year where the contractor used 5.6K concealed sprinklers (listed for LH), in an Extra Hazard occupancy handling flammable liquids. The owner thought the concealed heads looked better and apparently asked the contractor to change from the standard pendants without review or approval by the EOR. When I asked about the change they said the local fire chief inspected the area and didn’t say anything about them. So this verbiage really needs to be left up to the states as there are some variances across the country. In some areas, NICET IV is given more credibility and is permitted to perform design and engineering much like a PE for specific type projects. Craig L.

A design professional determines design criteria, a sprinkler contractor does system layout and calculations. It’s probably too late for the 2022 edition and probably too radical an idea for the committee to consider. Back to my resting mode.
