In this case study available to download in full from our website, Beca, a prominent advisory, design, and engineering consultancy, played a crucial role in the Christ Church Cathedral Reinstatement Project, a NZD 104 million initiative to rebuild the historic Christ Church Cathedral in Christchurch, New Zealand. The cathedral suffered severe damage in earthquakes in 2010 and 2011, leaving it unstable and in need of extensive restoration.
Beca provided surveying and monitoring services during the reconstruction, using a real-time monitoring system to track the stability of the structure throughout the construction process. They utilised Viotel wireless tiltmeters and vibration sensors in conjunction with Bentley's iTwin IoT platform to collect, analyze, and visualise live data, offering accurate and consistent readings.
The use of iTwin IoT significantly reduced the need for on-site visits, improving safety and efficiency. It also allowed Beca to share project information with various stakeholders through 3D visualisations, making the data more accessible and understandable. The system provided faster notifications of structural movements and enhanced decision-making during the complex restoration process.
