External path width obstacles
Street furniture should be placed adjacent to the accessible path but should not reduce its width to below minimum requirements. For consistency, street furniture should be placed along a continuous zone of the public realm to allow it share space with other objects that do not obstruct the accessible path.
External path width
The clear width of an accessible path should be above 1800mm. When there is proven to be restricted space, a minimum of 1200mm may be allowed. Materials of contrasting colour and texture should be used to define the edge of an accessible path. Passing Places Where the size of path is below 1800mm then there needs to wider passing places for two wheelchairs to pass easily. Passing places should be spaced at not more than 30 metres apart. Passing areas should be set back from accessible paths so not to cause obstruction to movement
Drop-off spaces
On street drop-off space Floor surfaces should be firm, stable and a maximum of 2% gradient for running and cross slope An access zone should be provided on the passenger side. Minimum overhead clearance of 3600mm Off street drop-off space Floor surfaces should be firm, stable and a maximum of 2% gradient for running and cross slope An access zone should be provided on the passenger side. Minimum overhead clearance of 3600mm
Accessible parking access zones
Perpendicular parking access zones Perpendicular space should have access zones to both sides and rear. Access zone to at least one side is mandatory. Access zones to side must extend entire length of parking bay.Side access zones can be shared with the adjacent parking bay Parallel parking access zones Parallel spaces should have access zone to road side. Access zone to rear is mandatory.Access zones to side must extend entire length of parking bay. In exceptional circumstances, access zones may reduce to 1500mm width if can be proven there is no other option. Diagonal parking access zones Diagonal space should have access zones to both sides and rear. Access zone to at least one side is mandatory. Access zones to side must extend entire length of parking bay. Side access zones can be shared with the adjacent parking bay
Accessible parking location
Accessible disabled car parking located on ground floor close to main entrance or secondary accesible entrance An accessible path must connect disabled car parking with building entrance
Ramp landing areas
Landing areas should be provided at top and bottom of ramps Landing areas to be provided every 9 metres on longer ramps Landings should be provided at each change of direction Maximum slope of landing areas to be 1:50 (2%) in any direction Top and bottom landings to be minimum 2100mm x 2100mm In exceptional circumstances, the size of landings can reduce to 1500mm x 1500mm Mid ramp landing areas should be minimum 1800mm deep x 2400mm wide Intermediate landings at the switchback of a U-shaped ramp (180° turn), should be a minimum of 1800 mm deep and 2400 mm wide. Intermediate landing located at the corner of an L-shaped ramp (90° turn), the depth and width of the landing should be a minimum of 1800 mm. Mid ramp landing areas
Ramp handrails
A ramp run that has a rise greater than 150mm should have handrails located on both sides of the ramp Upper and lower handrails should be provided on each side of the ramp Upper handrail located at 875-925 mm Lower handrail located 600-750 mm above the ramp surface. The clear width between ramp handrails should be 950-1100 mm apart Kerb Edges Edges of ramps and landing areas should be protected with wall, guard or screen Guard rails should comply with Kingdom of Saudi Arabia Building Code. Colour contrasting strip 40-60 mm wide across the full width of the ramp at the top and bottom of the ramp Handrails should return to post or wall.
Level changes beside external paths
If there is a change in level to the side of an accessible path that is between 200mm and 600mm then edge protection is required to avoid dangerous falls Edge protection should be a colour contrasted kerb at minimum of 75mm height If the change in level to side of accessible path is greater than 600mm then a guard rail that complies with Saudi Building Code is required.
Kerb cuts
Accessible path gradients should be maintained at kerb cuts where possible. Truncated dome detectable warning surface to be used. Floor materials need to be firm, stable and slip resistant. Drainage Kerb cuts should avoid water pooling by draining water away from path of travel. Flared sides The flared sides of kerb cuts should be distinct colour contrast to surrounding surfaces. Tactile warning surface Detectable tactile warning surfaces at kerb cuts required Warning paving should extend full width of kerb cut The change of level between kerb cut and roadway should be 10-15mm high
External stairs tactile warning surfaces
Tactile surface dimensions gap from stair: 300mm depth of surface: 600-900mm Horizontal Strip Dimensions separation of strips: 50mm width of strip: 20mm height of strip: 6mm
