In my situation I have an AHJ that is saying that a gridded system doesn't use branch lines but rather all piping components in a grid system are either feed or cross mains and so even 2" and smaller piping needs to be braced. I sent him a copy of the Appendix brace location examples for gridded systems in December and was hoping he would go away, but I may end up doing as Roland suggested and send in for a formal interpretation.

Tom, I feel that this should be clarified further. My understanding, at least as affected by the ICC Codes, is as follows: The 2003 edition of IBC removes the reference to the use of NFPA 13 from ASCE 7 2002 edition. (The version of NFPA 13 referenced is NFPA 13, 1999, NOT NFPA 13 2002). NFPA 13, 2002 TIA 02-1 was the "fix" for this snub, but IBC never actually issued a formal interpretation or Supplement judgement stating that. The 2006 edition of IBC does not have the same verbage removing NFPA 13 that IBC 2003 did, and also uses the NFPA 13, 2002 edition as the reference document, NOT NFPA 13, 1999, but does add other stipulations for its use. The 2007 Supplement to the 2006 IBC removes all remaining hurdles by simply adding a new section to the IBC 2006 Earthquake provisions, allowing the use of NFPA 13 , with no other stipulations. Please note that the NFPA 13 2002 version is STILL the reference document to IBC 2006, NOT NFPA 13, 2007. There is currently no version of IBC that references NFPA 13 2007.
