cannibalizing a bldg for another part of the bldg

[syarn]

Existing building. First built in 1876.

7 stories with mezzanine within 2nd floor level.

Floors 1 thru 5 are 49800 sf per floor.

The mezzanine is 22200 sf.

The 6 & 7 th floors are 8500 sf each.

The occupancy is a museum (A3).

198'x282' footprint. 3 sides have 60' clear frontage. 1 side is up against another building.

There is a fire alarm system with pull stations, smoke detectors.

however there is NOT a fire sprinkler thru out the building; just a limited sprinkler system in some areas.

the construction looks to be type I or II.

under 2009 international existing building code

in a 2400 sf exhibit area on the 3rd floor - renovating;

If the bldg owner starts grabbing ceiling tiles from an adjacent space that also is an egress pathway to the rated stairwell;

is the removal of these ceiling tiles to use in the renovated space a code violation?

 

[syarn]

no sprinkler in this particular space; not sure about the adjacent pathway;

If we're only addressing ceiling tiles..

I'd be okay with relocating the existing to the new space, provided they are not creating a greater hazard in the adjacent space/egress path. Could newer, non-matching panels be replaced in the adjacent space to maintain the ceiling?

Check with FD they might be in favor of opening up the space versus concealed space depending on what is above the ceiling

 

[zigmark]

At first read the reuse of ceiling tiles from one area to another seems fairly straight forward if they are the same as the damaged ones they are replacing. After thinking about all the possibilities there are lots of unanswered questions. Are they now or will they be part of a rated floor ceiling assembly? Do they meet the interior finish ratings required in the renovated space? What are your concerns is it their reuse or removal from existing location?

thx

mjesse-yes they could buy or find (hopefully not cannibalized from another space - ha) non matching tiles for the adjacent space.

zigmark-need to vet out if either ceiling is part of a rated floor ceiling assembly (I think the exhibit area has a plenum above it) and yes hard to tell if ceiling tile being reused is Class C: Flame spread index 76-200; smoke-developed index 0-450. concern was creating more hazard by removing from existing condition and now if the repurposing is also creating hazard.

Can anybody tell if the attached photo of the back of this ceiling tile is class C?its a usg ceiling tile....has some kind of thin "film" on the back - feels like plastic...the front side is painted brown which is what you see on the backside edges a bit.

If the tiles being removed are not part of a plenum, rating, or needed to make a srinkler system work, I can't see a problem with it......I would fins it hard to believe that USG would make something that does not meet at least Class C, but it is worth looking into....

thx

so upon closer checking it appears to be a foil backing my guess is it's "cheyenne" which if it is appears to be class A.

see jpeg for foil backing...

I agree, Class "A"
