BCAB #1753 - Measurement of Travel Distance, Sentence 22.214.171.124.(1)
September 18, 2014
Re: Measurement of Travel Distance, Sentence 126.96.36.199.(1)
The project is a 2 storey Group A, Division 2 club/amenity building in a residential townhouse development. The 2nd storey is used primarily as an open hall area.
Reason for Appeal
Clause 188.8.131.52.(2)(a) permits a single exit from an unsprinklered Group A floor area of less than 150m2 where the travel distance does not exceed 15 meters. Sentence 184.108.40.206.(1) requires the travel distance to be measured along the path of travel to the exit.
The appellant contends that the code does not specify any requirements on how travel distance must be measured. The appellant has proposed that the travel distance be measured along the exterior wall, and then travel diagonally through the center of the open hall area to the exit. This distance is 15 meters and is measured along the path of travel to the exit.
Building Official's Position
The building official maintains that travel distance must be measured along the exterior wall and then travel in a straight line to the exit. This orthogonal path accounts for obstructions within the floor area of the finished space. This distance is 17m, and thus the permission in Clause 220.127.116.11.(2)(a) for a single exit does not apply.
Appeal Board Decision #1753
For the purpose of Subsection 3.4.2. "travel distance” means “the distance from any point in the floor area to an exit measured along the path of travel to the exit". It is the determination of the Board that the method of measurement proposed by the appellant is reasonable and meets the Code’s requirements.
