ABSTRACT
Building Information Modelling (BIM) was implemented at the early concept design stage of the Sydney Metro West project to identify and analyse critical interfaces and develop a robust design. Automation and scripting tools were used on the federated BIM platform to save time and improve output accuracy, facilitate cross-discipline coordination and eliminate repetitive tasks. In combination, Leapfrog was used to interpret and visualise the distribution of the geotechnical units. The combination of BIM and Leapfrog models resulted in a powerful tool for interface impact assessment on Sydney Metro West – Eastern Tunnelling Package. This enabled the concept design team to visualise constraints associated with ground conditions and the dense built environment, and reduce the likelihood of impacts. This also facilitated ground movement impact assessment through parameter calibration.
