Sets out minimum requirements for elements of buildings and related facilities; in particular, access pathways, circulation spaces and fitments to permit access by people with disabilities. A set of transparent overlays of space modules to assist in the design of sanitary facilities is included. The Standard refers only to those technical requirements which are intended to be used with the current building requirements in Australia. Therefore, it does not refer to facilities such as lighting, shelving, work surfaces and hearing devices, nor does it refer to facilities such as baths and urinals, and specific design requirements for WCs suitable for people with ambulatory disabilities, as these are considered to be additional to minimum requirements for access and are included in Part 2 of the series.
