Information Modelling Based Tunnel Design and Construction Process

The present development situation of 3D and BIM based process model for tunnel design and construction methods has been studied. Tunnel design is generally done using traditional 2D drawing based working methods. As a basement for the research, the new specifications developed in Finland for national BIM requirements for infra sector were used. However, underground tunnels are not yet considered in these specifications. In a research project, a new concept how to use intelligent information modelling in tunnel works have been under development. For comparison, five different tunnel design and construction projects and work areas were studied and evaluated. A technicaleconomic evaluation for the future model of tunnel design and construction is also presented.
