ABSTRACT
The design, construction and operation of an infrastructure involve a large number of stakeholders (designers, urban developers, asset managers, local authorities, control offices, construction companies, environment experts, citizens . . .) and require more and more cross communications between these actors in order to insure a good construction with the respect of durable development objectives. Communication based only on documents and 2D-drawings has now reached its limits and it is time to introduce new working methods based, in particular, on virtual prototyping which has proved its capacity in other industrial sectors like aeronautic or automotive.
