ABSTRACT
During the design and the construction of a tunnel there is a constant need for updated geological/rock mechanical models, often visualized in specific software within the geological discipline. Tunnel design engineers handle the design in CAD software. Often there is a communication issue between those two disciplines. The GeoBIM concept is developed for efficient communication of any geo-related underground space data. The aim is to constantly supply all team members with quick access to the same data and models at the same time. The core of the GeoBIM concept is an efficient and flexible database that can import any data in any format and make it easily accessible. From the database data can be exported for further use. Within the GeoBIM concept it is possible to publish full 3D models, which is all navigable by using only the web browser. The GeoBIM concept is exemplified by two large Swedish tunnels.
