2. Discuss the significant changes to Administration
Chapter of the 2012 NC State Building Code.
a. Information contained in Sections 103 thru 116 is
superseded by information in the NC Administrative
Code and Policies or NC General Statutes.

3. Discuss the significant changes to the Definitions
Chapter of the 2012 NC State Building Code.
a. Slide 13: Some jurisdictions viewed as Group B
because of “clinic - outpatient” being listed in
Section 304.1.
b. Some viewed as I-2 because of the possible
ambulatory condition of the patients.
c. Slide 15: These occupancies have become
prevalent in response to economics of health care.
Ambulatory - incapable of self-preservation.
d. Slide 16: Much like I-2, but can be a larger building
based on Group B.
e. Slide 18: Smoke compartments are not required for
facilities less than or equal to 10,000sqft.
f. Slide 19: “Nonambulatory” in this paragraph refers
to patients that are not capable of self-preservation
because they are unable to walk at the time of the
event. The Patient may be sedated. The 30sf is for
a bed. Other occupants are expected to egress the
building and not be relocated to refuge areas.
g. Slide 20: A certain level of safety is achieved when
you pass into another smoke compartment. Like I2, the expectation is to “defend in place” for a period
of time.
h. Slide 22: I-2 requires the entire building to be
sprinklered instead of just the fire area.Staff is
expected to evacuate 3 or less occupants in beds.

i.
Slide 24: Emphasize that the public areas outside
the tenant space must have detectors.Buildings
fully sprinklered and not just the fire area
sprinklered are exempt from the requirement.
j. Slide 28: Review Section 424 at this time.
k. Slide 29: Except for safety provisions for sleeping
occupants in Group R occupancies and Group H
occupancies, Group A-2 and A-3 are the most code
stringent.

the new term Open Malls in the 2012 NC State Building
Code.

6. Discuss the significant changes to High Rise
Buildings in the 2012 NC State Building Code.
a. Slide 56: Soft Body Impact Classification Level
2 – Designer needs to provide test data from
third party testing agency that the assembly
meets this requirement.
b. Slide 58: Hard Body Impact Classification
Level 2 – Designer needs to provide test data
from third party testing agency that the
assembly meets this requirement.
c. Slide 65: Greater height has greater sway
which increases the stress on the bond
between the steel and the SFRM.
d. Slide 71: The main is configured so that a
single failure in the main cannot interrupt the
supply to the pumps.
e. Slide 72: This will restrict communications from
emergency personnel in the building with other
personnel outside the building. The steel and
concrete of a building restricts the ability for a
mobile unit to send and receive signals from
the outside to the inside of a building.
f. Slide 78: Stairs other than the “additional stair”
must handle the egress load. In fact the
remaining stairs must be sized to handle the
occupant load if one of them is blocked.
Section 1009 is “Stairways”. Section 1022 is
“Exit Enclosures”.
g. Slide 84: If occupancies other than A, B, E, I,
M, or R-1 is located more than 75’ and A, B, E,
I, M, or R-1 are located less than 75’ in the
same building then path markings are not
required.
h. Slides 86 – 115: Point out the different
luminous demarcation lines on the slides.
i. Slide 95: A discontinuity in the line notifies the
occupant that there is an exit opening at that
location. This means that maintenance of the
luminous material is critical. If some of the
tape is missing it could be mistaken for an exit
opening.
j. Slide 109: Uniformity helps prevents optical
illusions related to depth perception.

PRESENTER FEEDBACK
k. Slide 112: For most buildings this would
require charging illumination on the
photoluminescent material at all times. This
section is not allowing the material to be
charged up 60 minutes prior to the normal
business day.
l. Slide 115: How long is the material expected to
produce sufficient light? Is the fire service
going to annually cut the power to the stair and
check for sufficient glow?
m. Slide 118: This elevator and associated lobby
has features to ensure it is usable full the
duration that the shaft is intact.
n. Slide 122 -124: The lobby provides a place to
stage from. The firefighter only needs access
to one lobby for staging. If the elevator fails the
emergency personnel need protected access
to a way out of the building. Also gives them
protected access to standpipes.
o. Slide 130 - 133: Like the Fire Service elevator,
this elevator can be used for general public
access also. In an emergency you don’t want
people searching for the elevator that is for
self-evacuation.
p. Slide 134: Emphasize “prior to Phase I
Emergency Recall Operation”.
q. Slide 139: 903.3.1.1.1 contains exempt
locations for sprinkler heads.
r. Slide 145: 708.14.1 is “Elevator Lobby”.
Exception #3 allows the deletion of the lobby
when the smoke doors and fire rated door is
located at the elevator shaft. That would
defeat the purpose of the lobby for Occupant
Evacuation for staging of occupants waiting for
the elevator.
s. Slide 147: Lobby not needed at the level of exit
discharge as no one should be waiting to get
on the elevator at that floor.
t. Slide 149: Allows the occupants inside and
outside the lobby to make better informed
decisions based on what is on the other side of
the wall.

PRESENTER FEEDBACK
u. Slide 154: This lobby requires 4 times as many
wheelchair spaces as does a stair (1 per 200
occupants) because it is more likely that
persons in wheelchairs will be trying to selfevacuate.
v. Slide 155: Interestingly, no minimum dimension
is given.
w. Slide 175: Emergency personnel need to know
if a failure of the elevator is expected.
x. Slide 176: Can use a fire marshal “approved”
location if a fire command center is not
otherwise required.
y. Slide 178: Protecting the electrical support
system so that it functions for at least an hour.
The expectation is that the occupants will be
evacuated in 1-hour. The second hour of the
2-hour shaft (if required) is to protect the floors
for emergency responders.
z. Slide 181: May require both 2-hour walls and
floor/ceiling assemblies.

NC State Building Code.
a. Slide 208: 419.1 says in part, “…dwelling unit
or sleeping unit in which…”.
b. Slide 221: Emphasize “occupant load of 10 or
less” in 1008.1.9.3.If the unit has a calculated
occupant load greater than 10 then item #4 of
1008.9.3 does not apply.

9. Discuss the changes to the Means of Egress Chapter
of the 2012 NC State Building Code.
a. Slide 258: New Definition
b. Slide 259: The change in the “Level of Exit
Discharge” definition now classifies the level of
exit discharge as the entire story where the
transition from the exit to the exit discharge
occurs instead of the horizontal plane.
c. Slide 267: The 12 inches is always measured
perpendicular to the inside surface of the
handrail.
d. Slide 268: The 11 inches then connects the
two 12 inch measurement taken from the
handrail surface.
e. Slide 269: Adds language to clarify where
measurements are to be taken.The height is
now applied to any part of the lower surface
that is within 36 inches of the raised walking
surface.
f. Slide 271: Guards that are not provided to
prevent falling are not required to be 42” high.
g. Slide 273: No change to intent. It is just a
change in language for clarification of intent.
h. Slide 274: Lowered the height for alternating
tread devices and shipladders because of the
steep incline of these.
i. Slide 276: The 3/8 inch in Item #1 must have
something to with ornamental rails.
j. Slide 281: Single exits are now done on a per
story basis instead of per building basis.
k. Slide 282: Meet the worst case based on
occupancy type.
l. Slides 283 – 289: The table does not look
exactly like it is shown in this presentation
because the code format would not fit onto this
slide. This series of slides is displayed on a
per line of table basis. Associated notes for
the particular line are displayed on the
associated slide.
