Barrier testing of balustrades

by Ryan Durkin | March 31, 2026

When remediating or augmenting existing structures, it is not uncommon to find that certain elements do not meet current standards when assessed through first principles or modelling alone. Balustrades are a frequent example, particularly when upgrades involve increasing height, adding infill panels, or reducing climbability to meet modern safety requirements.

In cases where balustrades fall short theoretically, on-site load testing (or proof testing) can offer a practical alternative. Often, these elements prove to be more structurally capable than initial calculations suggest, allowing them to be retained with confidence.

Conducting onsite testing requires careful planning: confirming load requirements, identifying load application points, assessing site constraints such as space for test rigs, and ensuring safety protocols are in place in the event of failure during testing.

Proof testing provides a reliable way to verify balustrade capacity, helping to reduce project costs and preserve the original architectural intent of the building facade.
