BCAB #1515 - Exterior Wall acting as a Guard
July 5, 2000
Re: Exterior Wall Acting as a Guard
The project in question involves the enclosure of existing exterior walkways on the second and third storeys of an office building. An aluminum framed glazing system is being employed to enclose the opening between the top of a 30-inch high parapet wall and the underside of the walkway or roof overhang above.
Reason for Appeal
Article 188.8.131.52. specifies design loads for guards and Article 184.108.40.206. has load requirements for walls acting as guards.
The appellant contends that the infill glazing constitutes an exterior wall, not a guard. Therefore, Articles 220.127.116.11 and 18.104.22.168. do not apply.
Building Official's Position
The building official maintains that the new exterior wall, consisting of the existing 30 inch high wall and the new infill glazing, must comply with Article 22.214.171.124., "Loads on Walls Acting as Guards," or a guard conforming to Article 126.96.36.199., Loads on Guards, must be installed in front of the new glazing.
Appeal Board Decision #1515
It is the determination of the Board that both Articles 188.8.131.52.and 184.108.40.206. are applicable to the project in question.
