Résumé :

The paper presents on-going research aimed at the support of the management of
building projects and the aid cooperative design. Today, The use of systems adapt-
ed to the cooperative design assistance for the building domain is complex. This
results from the complexity of the cooperative work (difficulties in tracking actor's
work, lack of most of the required information, coordination problems, implicit
nature of most of the construction activities, etc.) The paper will briefly review
two data exchanging modes that we had defined. After, on the basis of this concept
of cooperative design we describe a new model of a virtual environment aimed
to takes into account the relational organization of the project and the semantic
meaning of works. This research represents a new approach because it not based
on management of documents but on all data relative to works. Finally, we use this
new model for defining a design-aided tool, to deduce advantages and limits of the
"Virtual Cooperative Project". This system lets geographically dispersed project
actors model the project context of a building. More specifically, it allows inter-
preting, using and exchanging project works in a centralized virtual environment
during the building life cycle. This system uses IFC objects which associate in the
same model the semantic and the 3D representation of building works.
