MATERIALS: Overhead projector or laptop computer and multimedia projector; projection screen; North Carolina Administrative Code and Policies 2009 Edition, North Carolina Building Code 2009 Edition, North Carolina Building Code 2012 Edition, Significant Changes to the 2012 NC Building Code Full Power Point Presentation.

MOTIVATION: To educate Code Enforcement Official’s on the changes to the 2012 NC Building Code, as well as provide Continuing Education.

TARGET: Certified North Carolina Code Enforcement Officials, Building Level I, II or II

Goal: This class designed to introduce certified NC Building inspectors to the significant code changes found in the 2012 NC State Building Code. This Lesson Plan is representative of six hours of continuing education.

SUMMARY: This presentation addresses the significant code changes from the 2006 IBC to the 2009 IBC including North Carolina Amendments. The 2012 NC Building Code is based on the 2009 IBC.

Not all changes are reflected, only those considered significant.

OBJECTIVES

Identify commonalities used throughout the presentation to show changes between the 2009 and 2012 NC Building Codes.
Slide 3:Time prohibits covering all code changes.
Slide 10:Noted “deleted text” is not delineated between ICC deleted and NC deleted.

Discuss the significant changes to the Definitions Chapter of the 2012 NC State Building Code.
Slide 13: Some jurisdictions viewed as Group B because of “clinic - outpatient” being listed in Section 304.1.
Some viewed as I-2 because of the possible ambulatory condition of the patients.
Slide 15: These occupancies have become prevalent in response to economics of health care.

Ambulatory - incapable of self-preservation.

Slide 16: Much like I-2, but can be a larger building based on Group B.
Slide 18: Smoke compartments are not required for facilities less than or equal to 10,000sqft.
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.
Slide 20: A certain level of safety is achieved when you pass into another smoke compartment. Like I-2, the expectation is to “defend in place” for a period of time.
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.

Continued Next Page:

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.
Slide 28: Review Section 424 at this time.
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.

Discuss the significant changes to Covered Malls and the new term Open Malls in the 2012 NC State Building Code.
Slide 43: Limit of 3 levels.
Slide 48: Trades off the open space width for additional fire-resistance-rating for the exterior wall for emergency personnel protection.

End of Presenter notes slides 39 – 49.

Discuss the significant changes to High Rise Buildings in the 2012 NC State Building Code.
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.
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.
Slide 65: Greater height has greater sway which increases the stress on the bond between the steel and the SFRM.
Slide 71: The main is configured so that a single failure in the main cannot interrupt the supply to the pumps.
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.
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”.
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.
Slides 86 –115: Point out the different luminous demarcation lines on the slides.
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.
Slide 109: Uniformity helps prevents optical illusions related to depth perception.

Continued on next page:

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.
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?
Slide 118: This elevator and associated lobby has features to ensure it is usable full the duration that the shaft is intact.
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.
Slide 130 - 133:Like the Fire Service elevator, this elevator can be used for general public access also. Inan emergency you don’t want people searching for the elevator that is for self-evacuation.
Slide 134: Emphasize “prior to Phase I Emergency Recall Operation”.
Slide 139: 903.3.1.1.1 contains exempt locations for sprinkler heads.
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.
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.
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.

Continued on next page:

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 self-evacuate.
Slide 155: Interestingly, no minimum dimension is given.
Slide 175: Emergency personnel need to know if a failure of the elevator is expected.
Slide 176: Can use a fire marshal “approved” location if a fire command center is not otherwise required.

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.

Slide 181: May require both 2-hour walls and floor/ceiling assemblies.

Slide 185: Section 714 of the 2009 NCBC is changed to Section 704 of the 2012 NCBC.
Slide 188: Does not include shear walls or bracing for wind loads.

Slide 201: The steel has to meet all of the applicable items of 1 thru 3.

End of Presenter Notes slides 185 – 204:

Discuss the addition of Live / Work Unites to the 2012 NC State Building Code.
Slide 208: 419.1 says in part, “…dwelling unit or sleeping unit in which…”.

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.

Discuss the changes to the Means of Egress Chapter of the 2012 NC State Building Code.
Slide 258: New Definition
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.
Slide 267: The 12 inches is always measured perpendicular to the inside surface of the handrail.
Slide 268: The 11 inches then connects the two 12 inch measurement taken from the handrail surface.
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.
Slide 271: Guards that are not provided to prevent falling are not required to be 42” high.
Slide 273: No change to intent. It is just a change in language for clarification of intent.
Slide 274: Lowered the height for alternating tread devices and shipladders because of the steep incline of these.
Slide 276: The 3/8 inch in Item #1 must have something to with ornamental rails.
Slide 281: Single exits are now done on a per story basis instead of per building basis.
Slide 282: Meet the worst case based on occupancy type.
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.
