hour) and T ratings (0 hour, 1 hour, 2 hour, 3 hour, or 4
hour) of the penetration firestop systems are at least the
same as the hourly rating of the assembly being pene-
trated.
(2) The penetrating firestop system includes the pene-
trating item as documented through testing of the
systems conducted by an independent testing agency.
(3) The penetrating firestop system is installed as tested.

3 ' MEMO
907 30th Street concerns about the different rated fire-barriers:
2015 IBC 707.5 states that "fire barriers shall extend from the top of the foundation or
floor/ceiling assembly below to the underside of the floor or roof sheathing, slab or deck above
and shall be securely attached thereto." The shaft enclosures and the stairwells do not meet
this code. They have joists, floor surfaces, and other obstacles breaking up this continuity of
the fire barriers.
2015 IBC 707.7.1 states that "penetrations into enclosures for exit access stairways ramps,
interior exit stairways and ramps, and exit passageways shall be allowed only where permitted
by Sections 1019.. 1023.5 and 1024.6, respectively." The stairwells do not comply with this
code and are not built as drawn on the plans.
1. 2015 IBC 1019 states that if floor openings containing and exit access stairway or ramp
doesn't meet the conditions below, it must be enclosed in a shaft enclosure constructed
in accordance with Section 713 of the 2015 IBC.
2. 2015 IBC 1023.5 states that penetrations into or through interior exit stairways and
ramps are prohibited except where the ductwork and equipment are necessary for
independent ventilation, pressurization, sprinkler piping, standpipes, electrical raceways
for fire department communication systems. Exception is membrane penetrations
allowed when protected in accordance with Section 714.3.2.
3. 2015 IBC 714.3.2 states "where walls or partitions are required to have a fire-resistance
rating, recessed fixtures shall be installed such that the required fire resistance will not
be reduced."
4. 2015 IBC 1024.6 states that penetrations into or through an exit passageway are
prohibited except for equipment and ductwork necessary for independent
pressurization, sprinkler piping, standpipes, electrical raceway for fire department
communication and electrical raceway serving the exit passageway. It also says that
there can't be penetrations or communicating openings, whether protected or not,
between adjacent exit passageways.
2015 IBC 713.7.1 states that "openings other than those necessary for the purpose of the shaft
shall not be permitted in a shaft enclosure. They have plumbing penetrating these shaft walls,
along with joists and it is not being built per the drawing and plans.
2015 IBC 1024.6 states "penetrations into and through an exit passageway are prohibited
except for equipment and ductwork necessary for independent pressurization, sprinkler piping,
