Do the Premises Standards require more circulation space than the current BCA?
Generally yes it does. The Premises Standards refers to a number of technical specification documents developed by Standards Australia the main one being Australian Standard 1428.1. This gives all the technical details on how to design and construct accessible features, AS 1428.1 is currently being upgraded to refect the new requirements of the Premises Standards. This will include increased circulation space in accessible toilets, most lifts, around doorways and on corridors where there is a bend of more than 60 degrees. The minimum width of passagways generally will stay the same as the current BCA, but there is a new requirement for passing spaces and turning spaces along passageways. Passing spaces are required every 20 meters where a direct line of sight is not available along the length of the passageway and turning spaces are required within 2 meters of the end of any passageway and every 20 meters irrespective of whether or not there is a clear line of sight.
