Located along the Arezzo-Florence rail line, the Borratino Viaduct spans 1,350 meters. Italferr was tasked with developing a structural monitoring system to determine existing and potential structural damage. However, they faced challenges surveying the structure while keeping it operational, as well as managing the voluminous captured data. They wanted to generate a 3D model to perform structural analysis and determine optimal placement of sensors for digital real-time monitoring, enabling proactive management and maintenance. Therefore, they needed comprehensive reality modeling and a collaborative digital twin platform. Leveraging ContextCapture, ProjectWise, and the Bentley iTwin platform, Italferr generated a 3D reality mesh and digital twin of the existing viaduct. Bentley’s applications reduced modeling times and provided a connected digital environment to analyze static and dynamic bridge behavior and identify optimal placement of digital sensors for real-time condition monitoring. The digital twin solution facilitates targeted, cost-effective maintenance intervention and will monitor about 1,500 infrastructure assets over a 10-year period, estimated to save EUR 70 million.
