Ensuring Compliance with Australian Standards for Concrete Stair Balustrades

If you would like me to assist with your project, please send an email to koshy@tek1.com.au with your project specifications. Kindly use ‘Raj’ as the subject header.

The Initial Requirements

The project specifications required the balustrade to be 1000mm in height, with the top and bottom rails positioned correctly. Specifically, the bottom rail was to be installed 120mm above the nosing line of the steps. This detail is crucial for both aesthetic and safety reasons, ensuring that the balustrade not only looks good but also provides the necessary safety measures.

Identifying the Issue

During the modeling phase, we identified a discrepancy: there was a gap exceeding 125mm at the raised locations. This gap was larger than expected and raised concerns about whether the installation would meet the required standards.

To address this issue, we submitted a Request for Information (RFI) with a proposed stringer plate to improve the appearance and close the gap. The client’s feedback was invaluable; they suggested adjusting the installation by setting the bottom rail 10mm below the original nosing line.

Achieving Compliance

With the client’s recommendation, we adjusted our approach to fix the bottom rail as instructed. This adjustment was essential for ensuring that the balustrade not only met the aesthetic requirements but also complied with Australian Standard AS 1428.1, which outlines the necessary specifications for accessible design.

By implementing this change, we confirmed that our installation now aligns with the standard’s requirements, ensuring both safety and compliance.
