This paper presents a concept for parametric modelling of mechanized tunnelling within a state of the art design environment, as a basis for the design assessment on different levels of details (LoDs). To this end, a parametric representation of each system component (soil with excavation, tunnel lining with grouting, Tunnel Boring Machine (TBM) and buildings) is developed in the information model for three LoDs (high, medium and low) and used for the automated generation of the numerical models of the tunnel construction process and soil-structure interaction. The platform enables a flexible, user-friendly generation of the tunnel structure for arbitrary alignments based on predefined structural families for each component, supporting the design process and at the same time providing an insight into stability and safety of the design. This model, with selected optimal LoDs for each component w.r.t. the objective of the analysis, is used for efficient design and process optimisation in mechanized tunnelling. Efficiency and accuracy are further demonstrated through error-free exchange of information between Building Information Modelling (BIM) and the numerical simulation and with significantly reduced computational effort. The results reveal that this approach is a major step towards the sensible modelling and numerical analysis of complex tunnelling project information at the early design stages.
