The National Carillon facade refurbishment project demonstrated a collaborative approach to the restoration of an iconic heritage structure, combining advanced digital technologies and spatial data with traditional restoration techniques.
The National Carillon, located on Queen Elizabeth II (QEII) Island, was originally opened in 1970. The Carillion was a gift to Australia from the British Government in 1963 to commemorate the fiftieth jubilee of Canberra’s founding as the National Capital. The Carillion is recognised as being of heritage significance and is listed in the Commonwealth Heritage List (ID105346).
In accordance with good asset management practice, a detailed structural inspection was undertaken by the National Capital Authority (NCA) to assess the condition of the facade and underlying reinforced concrete structure. The investigation identified defects with the façade panels, flexible waterproof sealant (façade joints) and water ingress.
The project goal was to restore and protect a national landmark for future generations to enjoy. A key outcome of the project was the repair and restoration of the ferrocement façade panels, the panels contain a unique blend of quartz aggregate and opaline glass that gives the Carillion a distinctive visual appearance.
The project implemented a 3D photogrammetry reality model as the central point of truth in near real-time, which transformed the project's execution, enabling spatial context for all defect identification, documentation, approvals, QA processes and as-built records. This resulted in significantly improved efficiencies in reporting and approvals and an improved outcome for the asset owner. Rather than storing volumes of project paperwork in archives, the project data is now readily available for future management of the asset.
The National Carillon project demonstrates how digital transformation shapes a more efficient, collaborative, and sustainable life-cycle approach to preserving and managing Australia's significant public infrastructure for generations to come.
