  BIM-to-FEM: Incorporating Numerical Simulations into BIM Concepts with Application to Real Tunneling Projects

  Finite element (FE) simulations are an integral element of the planning and design process for mechanized tunneling projects. The models needed for these simulations are typically manually generated using 2D-CAD drawings, which is a laborious and time-consuming process. Recent trends incorporating Building Information Modeling (BIM) concepts offer opportunities to simplify this process by using geometrical BIM sub-models as a basis for performing structural calculations. This paper presents a novel “BIM-to-FEM” technology, that automatically extracts the relevant information (geology, alignment, lining, material and process parameters), needed for a FEsimulation from BIM sub-models and subsequently performs an FE-analysis of the tunnel drive.
