AS 1428.1–2009 Clause 6.5.1Ĭlause 6.5.1 of AS 1428.1 states that: ‘The space required for a wheelchair to make a 60° to 90° shall have a gradient no steeper than 1 in 40 and shall be not less than 1500mm wide and 1500mm long in the direction of travel. Furthermore, the functional intent of the design specified by AS 1428.1 Clause 6.5.1 and Figure 4 is maintained without compromise. Having thought outside the box (pardon the pun), two simple rules have been deduced from AS 1428.1 Clause 6.5.1 which can be applied to determine other permitted corridor widths where there is a change in direction of 60 – 90°, and still achieving compliance with AS 1428.1. AS 1428.1–2009 Clause 6.5.1 prescribes the minimum dimensions for a 60 – 90° turn, and Figure 4 illustrates the permitted splay across the internal corner however, this is often interpreted in a way that can limit efficient design. The spatial requirements for persons in a wheelchair to manoeuvre where a change in direction occurs along a path of travel need to be considered within areas required to be accessible. Spatial requirements for points of change in direction
One of our staff members came up with a simple method to confirm whether a 90° turn complies with the requirements of AS 1428.1–2009 Clause 6.5 – be it on site or on plan.
