Do you have the 2009 IBC available? You're installing a 13R system? Would sprinkler protection be necessary in the attic space? If NFPA 13R and no sprinklers in the attic, then 3,000 sq ft draftstopping is needed. This would definitely be the architect's job to show these in my opinion. If no draftstopping is in the job, then your sprinkler scope extends to the attic. If you must use a specially listed head for this purpose and if this head requires 1000 sq ft draftstopping then it seems better to add the 3000 sq ft draftstopping (or two units) and omit the sprinklers.
Have I interpreted this correctly, aside from any Marriott special requirements? Bill Brooks William N. Brooks, P.E.

How have you been dealing with architects and GC's that state the IBC does not require draft stops in an attic, so they are not willing to put them in when the CC heads are req'd and the CC heads require a draft curtain to be installed?
