Ada Ground And Floor Surfaces

302 floor ground surfaces.

Ada ground and floor surfaces.

403 2 floor or ground surface. Wheelchairs move most easily on hard stable and regular surfaces. 403 4 changes in level. Soft loose surfaces such as sand or gravel wet clay or cobblestones can make it difficult for wheelchairs to move in ease.

Walking surfaces shall provide clearances complying with 403 5. 502 4 floor or ground surfaces. Stable surfaces resist movement while firm surfaces resist deformation by applied forces. Accessible surfaces remain unchanged by external forces objects or materials.

Changes in level up to 1 4 in 6 mm may be vertical and without edge treatment. Openings in floor or ground surfaces shall not allow passage of a sphere more than 1 2 inch 13 mm diameter except as allowed in 407 4 3 409 4 3 410 4 810 5 3 and 810 10. 306 knee and toe clearance. Specifications for floor and ground surfaces address surface characteristics carpeting openings and changes in level.

404 doors doorways gates. Required clearances including clear floor space wheelchair seating spaces turning space and door maneuvering clearances. Interior and exterior accessible routes including walking surfaces ramps elevators and lifts. 305 clear floor ground spaces.

Hardened materials such as concrete asphalt tile and wood are sufficiently firm and stable for accessibility. Accessible floor and ground surfaces must be stable firm and slip resistant. Ada ground and floor surfacesalong accessible routes must be stable firm and slip resistant. Floor or ground surfaces shall comply with 302.

Parts creating horizontal or vertical joints in these surfaces shall be within 1 16 inch 1 6 mm of the same plane as the other. Changes in level are not permitted. Stairways that are part of a means of egress. The cross slope of walking surfaces shall not be steeper than 1 48.

The ada discusses ground and floor surfaces in section 4 5 where they say in general that. Elongated openings shall be placed so that the long dimension is perpendicular to the dominant direction of travel. The running slope of walking surfaces shall not be steeper than 1 20. Swinging door and gate surfaces within 10 inches 255 mm of the finish floor or ground measured vertically shall have a smooth surface on the push side extending the full width of the door or gate.

Access aisles shall be at the same level as the parking spaces they serve. 303 change in level. Changes in level shall comply with 303.
