To what Roland says, 905.3.1 does not require automatic standpipes in a building, only that standpipes are required based on absolute height or buildings four stories and higher. The special requirements for high-rise buildings are in other sections of the building code and in NFPA 14.
SML From: Sprinklerforum [mailto:[email protected]] On Behalf Of Roland Huggins Sent: Wednesday, November 01, 2017 12:46 PM To: [email protected] Subject: Re: Standpipe Pressure Question. This section of the IFC is, let’s say, horribly written. 905.3.1 starts off say ALL shall be Class III then provides an exception whereby Class I is allowed when the building s fully sprinklered. Then 905.3.2 specifically calls for a Class I for large Assembly occupancies (occupant load over 1,000). NFPA 14 is much cleaner but let’s let the Chair of that TC comment on correlation with the IFC. Ball teed-up. Whack it Steve.
