ABSTRACT
Building Information Modelling (BIM) is a method used to plan and manage projects based on 3D-models. Linking the 3D-models to the dimensions of “time” (4D) and “costs” (5D) generates the so-called process model which gives rise to a graphic project management tool. Tunnelling projects are unique when it comes to time and cost tracking, especially since the works are executed in an unknown underground environment. The anticipated geology is based on an interpretation of geological investigations prior to the start-up of the works. During the execution phase, deviations are commonplace. The way this is to be shown has to be incorporated in the process model in an appropriate way and should be agreed upon by all parties involved. Such methods are being used in the current “Albvorland Tunnel” project in order to gain insights into the future use of BIM on large-scale infrastructure projects.
