Taking Advantage from Building Information Modelling and Digital Data Management in TBM Tunnelling
Tunnelling projects are notorious for exceeding time and cost limits, which are often a consequence of inaccurate interpretation of information and therefore wrong predictions. The prediction quality, however, can be significantly improved by digitalisation of design and construction processes. The contribution summarises the current instruments and possibilities in the digitalisation of the tunnelling process as well as the benefits of a mutual information sharing between Contractor and Owner. The quality of decisions can be considerably improved by facilitating the perception of significant information and presenting to decisionmakers a more complete picture of the project. To obtain a full, transparent picture, this information requires a common framework, e.g. Building Information Models (BIM), which renders data easily accessible and indicates relevance, thus diminishing false bias and provide information that accounts for previous experience, scientific facts, statistical significance and incorporation of large amounts of data. All partners of the project benefit from collaborative information sharing. With transparent information on the project status and its boundary conditions, conflicts can be easily settled or prevented. Shared resources and open communication throughout the project help establishing an environment for concerted settlement of conflicts with the mutual goal of steady improvement of the project.
