Well then we agree we disagree, not a problem. Would be a better world if every agreed with me (mwahahahaha) but it would also be boring, lol.
Right or wrong I did something similar once as an AHJ and for my life can't recall the specifics. I did win in that in the end the issue was resolved my way. Never got to a judge I'll admit. I only lost once as an AHJ on a standpipe issue and a man of God representing the Cathedral was on the other side of the table. Up against God I knew I didn't really have a chance. My full code path is from the '02 NFPA 13 3.5.5 definition of a riser to 8.15.4 requirement to protect risers by...other approved means. No place in 13 describes how to protect so I look in the Code that adopts the standard and find nothing. Which then invokes 102.7 and off to the IPC/FM/other NFPA documents/listings. I believe the reliability of the sprinkler system does fit into the overall scope of the IFC. But the use of those sections can be more specific. Even if you don't like the IFC sections the AHJ still has George by the short hairs with 8.15.4 other approved means. He's saying the other approved means is IPC/IMC. Think the judge is going to overrule. I don't. Certainly seems reasonable to use another reference on how to that has the exact same purpose - to protect pipe from damage. It would be up to George to come up with something within our family of codes and standards to refute going outside. Sorry George but if it gets to court I don't see you winning. I promise I'm not for hire to the AHJ or his legal team. Don't get me wrong a simple nail plate from the average home improvement store is sufficient for nearly all applications IMHO. Going to the specificity of the IPC/IMC seems a little ridiculous. Chris Cahill, P.E.

The Scope is found in IFC 2006 101.2 Also, according to IFC 2006 102.6 Referenced Codes and Standards, "the codes and standards referenced in this code shall be those that are listed in Chapter 45 and such codes and standards shall be considered part of the requirements of this code to the prescribed extent of each such reference." The commentary to IFC 2206 102.6 states: "the application of referenced standards is limited to those portions of the standards that are specifically identified." Please note that in IFC 2006 Chapter 45, where the reference standards and codes are listed, IPC 2006 305.8, and IMC 2006 305.5 are NOT specifically listed/referenced.

You have found the references within each Code, but do the Codes apply to Fire Suppression piping? Read the SCOPE of each document and you will find that it does NOT include Fire Suppression piping.

IMC 2006 305.5 Protection against physical damage.

Here's how we deal with this. We nail plate the sole plates(one or up to 3 depending on the construction, houses with gypcrete floors typically have an extra plate or two depending upon how thick the gyp is.) and slip a steel sleeve around the riser coming thru the plate.(We find we have enough scrap pipe around to keep a constant supply of 8" sleeves. We use 8" because we have base moldings here that go to 10" high on occasion.) Most walls we see are double plates at the top. Only the upper plate is the actual "Top Plate" the second plate has a name I forget right now. Any way we nail plate both plates and have our "Nominal" 2" below the top plate. We've never had any problem with doing this from any inspector. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

He stopped by a jobsite where we're installing CPVC in walls, and found fault with the nail plates we're using. I called to follow up on why he didn't like them, and asked for a code reference. He replied even if it wasn't in the code, he'd enforce nailplates extending further than ours as a safety issue. So I reminded him that his authority was to enforce the PA UCC as adopted, not safety issues he took a personal liking to. His code reference arrived by USPS this AM. He cited the IPC and IMC as applicable to sprinkler piping, which I disagree with. Any thoughts or previous rulings by other AHJs?
