Stair Calculator For Comparing AS1657 and NCC/BCA Requirements




Simple spreadsheet (MS Excel) calculator to visually compare compatibility between BCA/NCC compliant stairs and AS1657 stairs, based on rises and goings. As the diagram above illustrates there is only a small region of overlap between the two codes.

As far as possible when I design stairs I try to make them compliant with both AS1657 and the BCA, so as to allow for future changes in the use of the building space.
