Memory care facility smoke partitions - 2009 IBC

[Chris_Sanders]

Good morning-

I'm putting together drawings for a memory care facility (I-2) w/ type II-B construction, fully sprinklered. Chapter 4 has some requirements specific to I-2, including the required locations of smoke barriers and smoke partitions. What I *don't* see is a requirement for wall construction - smoke or rated - for walls between the units themselves. We're putting this facility into a renovated space w/ high roof deck, and I'd like to avoid having to run these walls up to the deck if possible.

Thanks in advance for your insight and assistance!

Steveray-

Saw this...since we're I-2 (Section 407), I don't think that 709.1 pertains to the walls between the units.

Thanks!

cda-

Yes, we're required to meet NFPA 101-2000.

Thanks!

711.3 Fire-resistance rating. Unless required elsewhere in the code, smoke partitions are not required to have a fire-resistance rating.

We amend the heck out of alot of stuff.......Our amendments get rid of the reference to 420....So if there are dwelling units, they get something...But by pure IBC it would appear that nothing is required...

Chris_Sanders, Welcome to the forum. Wherever the Code requires a rated assembly Chapter 7 tells you how to build it. Chapter 7 is to Fire Resistance Rated Assemblies as Chapter 9 is to Fire Protection Systems.

I can't remember what a memory care facility is about. Come to think of it, I may have never known. Ya that's the ticket, I'm clueless.
