ABSTRACT

Sustainable and resilient infrastructure plays a crucial role in achieving long-term development goals. Engineers, armed with expertise, design and construct infrastructure that withstands the test of time. Leveraging Digital Twins and Building Information Modeling (BIM), it’s possible to assist in the planning and execution of maintenance of disused assets, ensuring their performance and safety. The rehabilitation of such assets it’s crucial to enable the sustainability of infrastructure in urban environments, where there are complex interferences and logistics conditions.

By digitally representing complex structures, BIM enables early identification and mitigation of critical points during the design of disused assets. The proposed case study analyzes the rehabilitation of a disused tunnel with masonry lining in Genoa’s historic harbour area. Starting from the survey and investigation data, the authors present the digital workflow and software to model the tunnel during the design phase and the early construction stages. OpenTunnel Designer is integrated with minimally invasive technologies for data acquisition and it has been utilized to digitally model and analyze the disused tunnel. The digital twin is combined in a pilot project with iTwin IoT to remotely monitor, analyze, and manage sensor data. The pilot project will ensure the feasibility of the solution and the actual workflow to extend the applicable solutions during construction.
