RAMPS:
According to the Canadian Standard Association (CSA): 5.5.1 Running slope and length A ramp shall have (a) a running slope with the ratio between 1:12 (8.33%) and 1:20 (5%); and (b) a distance between level landings not longer than 9000mm. 5.5.2 Cross slope The cross slope of the ramp surface shall not be steeper than the ratio of 1:50 (2%). 5.5.3 Width The clear width on a ramp shall be at least 920 mm. 5.5.4 Landings A level landing shall (a) be provided at the top and bottom of each ramp; (b) beprovidedatallchangesoframpdirection; (c) be at least as wide as the widest ramp leading to it; (d) havealengthnotlessthan1500mm; (e) at door ways serving an accessible route,have an area of atleast 1500 × 1500 mm  |
SIDEWALKS: Any sloped walkway less steep than 1:20 is designed as a sidewalk. Unlike ramps, side walks do not require a hand rail or edge protection.  |
