Sorry. This is F-2 <12% alcohol. So no separation issue. But still a vertical 
opening issue.

I'm sure the AHJ would balk at considering a restaurant as an F-1.

So it sounds like there are several issues.  First the architect needs to 
revisit and verify the separation requirements between an F-1 and an A 
occupancy.  If the findings indicate that a 1-hour separation is required, 
don't forget that is not just walls but floor/ceiling as well.

Is there the possibility of providing glazing around the perimeter of the 
opening floor to roof deck above and then providing the type WS sprinklers by 
Tyco which are listed as providing the equivalence of a two-hour separation?

Do the whole building is F-1 with an open restaurant inside?

So, is the A occupancy on the first floor and F-1 is the second floor?

Is there seating on the first level and the opening is so you can see the 
equipment on the second floor?


Per the IBC, for a fully sprinklered building there is a 1-hour fire separation 
requirement between F-1 and A.  (Table 508.4)

If that is the case, someone has a problem that sprinklers cannot fix.

Is this like an atrium?

What's the occupancy?

Any fire rating of floor/ceiling between levels?
