Construction Process Simulation in Tunnel Construction – A Prerequisite for Automation

Construction process simulation allows producing a virtual copy of an existing or planned construction site. The detailed analysis of construction processes and construction logistics with the support of simulation models creates a better understanding of the performance defining aspects. In many construction sites, the actual performances lag behind the planned levels. This is due to the insufficiency of planning instruments. The authors have performed an in-depth analysis of the internal supply chain of an actual tunnel construction project. While the presented study has focused on the inner outfitting of the existing tunnel, similar work has been done for the excavation processes by the authors. The paper reviews the role, simulation plays for construction planning and investigates the benefits of simulation as a step towards increased automation levels.
