The digitalization of the Tunnel Schöneich-Using a digital twin to improve operation and maintenance workflows of an existing road tunnel

Abstract

The refurbishment of the existing Tunnel Schöneich at the entrance of the city of Zurich is part of the big project of the Swiss Federal Roads Office (FEDRO) called “Cover-ing Schwamendingen”. After the complete renovation of this existing tunnel, a digital twin for the operation and maintenance of the entire tunnel and all technical equipment’s has been developed. Starting from the survey of the internal geometry of the tunnel with laser-scanning technology and from the documentation coming from the design and the construction phase, passing through a recognition of the information needed for its operation and maintenance the goal was to provide a Digital Twin for the life cycle management of this tunnel, using the Building Information Modelling method. By adopting an openBIM approach and a structured data management system, it has been possible to test how to manage all the information and classification needed for the operation and maintenance of this asset in any kind of digital platform with any downside of data lock-in.
