Hi Laura, "We are considering allowing a hardship" leads me to believe that you are the AHJ. One person's opinion. The federal advisory is meant to address curved ramps or slight changes in direction, not 45 degree changes, certainly not 2 in succession. Looking back at prior standards for ANSI intent reveals that intermediate landing was previously based on changes of direction of 30 degrees, which is significantly less than 45, and as I allude, I think you are actually looking at a change in direction of 90 degrees here since they are juxtaposed. Of course, I am ignorant of the details of the project and that makes a difference in the standard of care required.
The type of project may allow deviations from standards for other reasons (is it strictly barrier removal at existing site, or alteration, or new construction?). The standard of care for strictly barrier removal may allow deviations from standards if they are safe and there is a hardship. The standard of care for alterations and new construction are much higher and would allow such a deviation only in extremely rare circumstances. A federal 9th circuit appeal decision established that there is zero tolerance in new construction for deviation from standards. If this is new construction or an alteration, this is very dangerous ground for the owner if challenged, even if there is a hardship. Moreover, I can't see a hardship from the information provided. I am not addressing whether it is usable or not. different question, and one where the answer only matters if this is strict barrier removal at an existing facility. This may not be the answer you are looking for but I feel strongly about it.
