FAQs - Case Study Related

Re: Case study Director’s Office:

Q: If you add sprinkler heads does the scope of work become reconstruction?

Maybe, if you disable the fire safety system during the work. In this case, declaring the scope of work as reconstruction would have had minimum impact.

Re: Case study Plan Review at 700 N. Tryon Street:

Q: What if the new partitions negatively impacted the travel distance of the egress?

You cannot go backwards in compliance. Section 1.6g (1) states the work shall not make the building less conforming with the Basic Requirements of this code than it was before the alteration was undertaken.

Re.: Case study Atherton Mill:

Q: To utilize lath and plaster wall finish as a one-hour wall do you have to be historic?

No, Sec. 1.33 b 3 Historic Buildings states “where one hour fire resistive construction is required by this code, it need not be provided regardless of construction or occupancy where the existing wall and ceiling finish is lath and plaster.” Sec. 1.31 c 2 (1) Change of Use also addresses lath and plaster in that existing lath and plaster in good condition shall be accepted where a one-hour fire separation assembly is required by NCSBC 1004.3.2.1, Construction.

Re: Case study 37 Biltmore Avenue:

Q: How is it determined that this building would need a second exit from the first floor restaurant occupancy?

If this building is being reviewed under the 1999 NCRC then the restaurant classification is “B”. Section 1.17a.2 of the NCRC states that a single exit is permitted in the story at the level of exit discharge when the occupant load of the story does not exceed 50 and the exit access travel distance does not exceed 75 feet. The referenced case study has a travel distance of exit more than 75 feet therefore a second exit is required. To carry the question further, if the building were reviewed under the 2002 NCRC then the use classification is “A2”. Section 1.13b.1 of the NCRC also references the 75-foot travel distance.

Re.: Curtain Beauty Shop study case:

Q: How often will doing electrical work force the scope into reconstruction?

Not often, only if the entire electrical system were involved.

Q: What if we do the basement?

Not an issue unless you do over 50% of the square footage, then you would have to sprinkler the building. (Note: this gives the owner options as to scope of work area.)
