BCA Requirements
Design issues are driven by regulatory requirements in the Building Code of Australia. It governs geometric constraints required to make stairs and balustrades safe and easy to use. For instance, hand rails and balustrades are needed where the building occupants access areas with more than a 1.0m change in level. Other issues centre on the height, width, rake and spacing of elements. Strength and durability are also important, particularly in exterior applications.
