AS1428.1:2021- Technical article 1-Application of 1500mm clear width to Curved walkways/ramps


AS1428.1:2021- Bite size technical article 1 - Application of 1500mm clear width to Curved walkways and ramps

AS1428.1:2021 (Desing for Access and Mobility) Clause 7.4(f) Curved walkways, ramps and landings

The AS1428.1-2009 Clause 10.4 the following for curved walkways and landings requires:

The clause caused confusion in the following areas:

  1. What is the definition of a 'curved' walkway or ramp? Would say a gentle 20M radius walkway still be considered to be a ‘curve’ and require 1500mm clear width?
  2. What would the junction of a 1000mm straight walkway with a 1500mm curved walkway look like?

To clarify this the AS1428.1:2021 has been updated to state the following:

  1. Intersects with each other along the centreline
  2. The change in width from 1000mm (straight component) to 1500mm (curved component) is to be accommodated within the length of the 1500mm long straight landing.
