A tight space is in need of a ramp. The problem is the ramp has two 45 degree turns without landings. The 2013 CBC applies to this project. We are considering allowing a hardship as long as the cross-slopes comply. I've attached the drawing in question. It appears the cross-slopes work on paper. Any advice would be appreciated.
From CBC :
"IIB-405.7.4 Change in direction. Ramps that change direction between runs at landings shall have a clear landing 60 inches (1525 mm) minimum by 72 inches (1829mm) minimum in the direction of downward travel from the upper ramp run."
An advisory from US Department of Justice states:
"Advisory 11B-405.7 Landings. Ramps that do not have level landings at changes in direction can create a compound slope that will not meet the requirements of this chapter. Circular or curved ramps continually change direction. Curvilinear ramps with small radii also can create compound cross slopes and cannot, by their nature, meet the requirements for accessible routes. "
