Paths of Travel

Common Issues

• Abutment of surfaces not having a smooth transition
• Tolerances for abutment of surfaces exceeding 3 mm vertical or 5 mm where beveled or rounded

Design

General

Architect to:

• Display any crucial clearance measurements in a different way (for example, as a dimension in a box) so that everyone is aware of them during design and construction.
• Slightly reduce the ramp grades from max to allow for construction tolerance
• Add dimensional tolerance for max and minimum dimensions to the drawings.
• Check important clearances are between skirting (not walls)

Continuous accessible paths of travel

• Slip resistant surface with a texture that is traversable by people who use a wheelchair
• Height - 2000 mm minimum unobstructed or 1980 mm at doorways
• Width - 1000 mm minimum unobstructed unless otherwise specified (such as doors, curved ramps and similar)
• Fixtures or fittings – not intrude into the minimum unobstructed width including door handles below 900 mm

Abutment of surfaces and floor coverings

• Smooth transition.
• Design transition - 0.0 mm.
• Construction tolerances
• 0 + or – 3 mm vertical
• 0+ or – 5 mm, provided the edges have a beveled or rounded edge to reduce the likelihood or tripping
