403.2.1.1
Type of construction. The following reductions in the minimum fire -
resistance rating of the building elements in Table 601 shall be permitted
as follows:
1. For buildings not greater than 420 feet (128 000 mm) in building
height, the fire-resistance rating of the building elements in Type IA
construction shall be permitted to be reduced to the minimum fire-
resistance ratings for the building elements in Type IB.
Exception: The required fire-resistance rating of columns
supporting floors shall not be reduced.
2. In other than Group F-1, M and S-1 occupancies, the fire-
resistance rating of the building elements in Type IB construction
shall be permitted to be reduced to the fire-resistance ratings in Type
IIA.
3. The building height and building area limitations of a building
containing building elements with reduced fire-resistance ratings
shall be permitted to be the same as the building without such
reductions.
SEE
EXPLANATION
This project uses special provisions within the building
code to create a “podium” scenario where the bottom 2
floors are type 1A construction, with a 3 hour horizontal
fire separation at the 3rd floor line; separating the upper 4
floors of type 5A wood frame construction from the lower
type 1A construction. The building is effectively broken
into (2) separate buildings at this location. (Horizontal
Building Separation Allowance (IBC section 510.2).
Because of this requirement, no reductions in fire ratings
per this IBC section 403.2.1.1 will be used. All concrete
columns and beams at floors 1 and 2 supporting the entire
building floors 3 thru 6 above; will be fire rated to not less
than 3hrs.
403.2.1.2
Shaft enclosures. For buildings not greater than 420 feet (128 000 mm) in
building height, the required fire-resistance rating of the fire barriers
enclosing vertical shafts, other than interior exit stairway and elevator
hoistway enclosures, is permitted to be reduced to 1 hour where automatic
sprinklers are installed within the shafts at the top and at alternate floor
levels.
NO
REDUCTION
NEEDED
Exit Stairway Enclosures and Elevator hoistway enclosures
are constructed using fully grouted and reinforced 8”
concrete masonry units achieving a continuous 2hr fire
barrier rating.
All other shafts within the building needed for mechanical
means or other items, will be constructed using shaft liner
panel systems achieving a continuous 2hr rating. No
sprinklers will be installed in these kinds of shafts. In most
cases, these kinds of shafts will not extend the full height of
the building, but rather start/stop at fire rated floor/ceiling
constructions and become fire rated penetrations at those
locations, instead of actual shafts. We will show this in
detail for building plan submission.
