Be gentle, now.........I appreciate that you said only "no gold star" instead of going off on a rant about incopitent engineers. Some of us do try to learn and willing to listen to reason........

If the space is totally enclosed then there is no access for storage and no head is required if the stair is non-combustible. The spec is correct. <sigh> The Engineer has taken some license on his quote of the 13 section. The word "accessible" is not in the script. So no gold star for him. NFPA 13, 2007 - 8.15.3.2.1 "In noncombustible stair shafts having noncombustible stairs with noncombustible or limited combustible finishes, sprinklers shall be installed at the top of the shaft and under the first landing above the bottom of the shaft."

The spec for the job states that "Sprinkler shall be installed at top of shaft. Space below first landing is considered concealed, non-accessible, non-combustible, and hence does not require sprinkler protection." he engineer who is reviewing my plans sent me an email stating the following: *8.15.3.2 Noncombustible Construction.* *8.15.3.2.1 *In noncombustible stair shafts having noncombustible stairs with noncombustible or limited-combustible finishes, sprinklers shall be installed at the top of the shaft and under the first accessible*landing*above the bottom of the shaft. We always took this to mean the sprinklers are required under the first landing? And by accessible we took this to mean access could be provided by a access panel.." Is this the way I should be interpreting the code? Do I still have to sprinkler under the landing and make sure there's an access hatch? or should I be able to omit it like the spec indicates? I have been following this forum for a while now. This is the first question I have posted. - Cory _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
