Use case 6 studies the special case of interactions between infrastructures and their environments at different stages of a project. The objective is to examine how these studies could incorporate BIM.

During phase 1, two cases were considered:

  • studies linked to noise, in particular the case in which a noise barrier is built together with an infrastructure;
  • studies relating to wildlife crossings and compensatory measures linked to the existence or construction of an infrastructure.

By studying these special cases, the aim was to better understand practices, the use of data and the difficulties of using 3D data.

The work in phase 1 demonstrated that there is major specialisation in terms of skills and actors on the one hand, and that there is a great deal of complexity in the use of data and software on the other. As each project involves a large number of tasks, actors are specialised in particular domains (see report UC6.1 on noise, for example). Modernising by shifting towards the use of digital data does not therefore require a single element to be changed, but rather a collection of software, processes and methods. The software used is often multifunctional, and learning how to use it is no trivial matter.  The most acute problem is surely the fact that the digital data describing infrastructures are not seen as databases but as the internal elements of proprietary software, which does not facilitate their interoperability.

The reports written by the UC6 group in phase 1 introduce elements that show the complexity of the processes, software, actors and exchanges. Given the specialisation in terms of skills, it was not possible to obtain, as we would have liked, information on the use of 3D digital data for wildlife crossings or on the archiving of data, which are two points we consider essential for the future. These studies will form the subject of phase 2.
