In the Architecture Engineering and Construction (AEC) sector, cooperation between actors is essential for project success. During the building construction activity, organization is both hierarchical, transversal and adhocratic. Moreover coordination mechanisms are strongly dependant on trust perception by the actors. New assistance tools have to integrate these heterogeneous parameters. The proposition described here consists of the design of a coordination tool providing indicators (about coordination and trust) and also allowing the user to navigate in the cooperative context through multiple views. This proposition is based on a model architecture allowing us to manage cooperative context information and its (multi)visualization.
