We get those cross referenced type specs now and then.

For mechanical piping, plumbing, duct, etc, SMACNA.

For Fire Protection,  NFPA 13. SMACNA isn't referenced in the NFPA INSTALLATION 
Standard, because 13 has it's own rules to follow.  

SMACNA is also no longer referenced in the IBC as of the 2003 edition.  ASCE 7 
was established as the accepted standard.  However there was some verbiage 
placed in the Code which would permit acceptance of other design standards if 
approved by the AHJ.

So if the MEOR wants to apply SMACNA to Mechanical piping and duct systems he 
needs to request permission from the AHJ to use that standard.

But as previously stated,  NFPA 13 is the applicable standard for design of 
seismic bracing for Fire Protection service piping not SMACNA.

Subject: Seismic Restraint Standards

Forumites:

General Mechanical specs often refer to SMACNA for seismic restraint of piping 
systems. Sprinkler specs often refer to General Mechanical.

Question: Does NFPA 13 seismic bracing requirements take precedence over SMACNA?

How was the battle won with the MEOR when he says SMACNA is the preferred 
standard for bracing of piping systems?

Any comments would be appreciated.

Thank you,
Ed Cyr
