Currently there is no uniform and consistent documentation of unexpected standstills available, which can be applied during the excavation of tunnels with tunnel boring machines (TBM). Such a documentation and evaluation would be helpful for the estimation of risks, costs and the advance rate for future tunnels excavated with a TBM. An approach for a documentation of unexpected standstills of hard rock tunnel boring machines, such as open gripper TBM, single shield TBM and double shield TBM, was developed at Graz University of Technology. This paper shows the results as well as the benefits of a detailed and continuous event documentation during tunnel excavation. The new approach can be taken as a basis for future documentation of unexpected standstills in TBM tunnelling.
