Abstract: The Building Information Modeling (BIM) is getting more and more common into building construction, but it hasn’t been developed into underground work so far, although it would be very useful. Indeed, underground works strongly interact with their environment, and with many different stakeholders, whose data are partitioned into their own field. In this paper, a study dedicated to the development of a new decision support system is presented: it is a 3D visualization interface dedicated to worksite’s technical management. This tool is focused on tunnel boring machine (TBM) projects. Its main assets are:
  • To have a 4D (3D + time) model, built in real time thanks to the connection to different databases of the worksite.
  • To integrate data that comes from different fields such as: TBM excavation parameters, geological data (3D block model describing the lithology and rock alteration), buildings, tunnel as-built, stations, geotechnical and structural monitoring (settlement for example).
Until now, there has been no integration of these data into one single tool, making analyses of their mutual impact on each other quite complicated and tedious.
