Construction sector utilizes many disciplines, knowledge and know-how in design and manufacturing process. Each one evolved independently, with its own terminologies, suitable technologies, and specific means to express and communicate information. This fragmentation, often source of richness and diversity, causes many problems of information losses and communication difficulties between actors; these problems also exist within the same trade. It is clear that bringing this state of work to a collaborative method in building design and manufacturing, pass obligatory by setting up a tool of interoperability among actors from different trades and different stage in the building life cycle.
Our objective is to bring closer these actors in work around a common building design process where each actor can have his own specific point of view well represented. This fact shows well that it exists a real problem of definition of the building design process (each actor has a specific point of view not necessary the same with the other actors).
Going beyond the actual fractionation in the building design process, means for us, dropping traditional design approaches, based on classic representations of the building life cycle and classic exchange rules between actors. This thesis proposes to set in a new modelling approach representing the building product according to the different actor's point of view, and evolving in a dynamic collaborative work environment. This conceptual model brings closer the actors to a common and shared view of the building, without intervening in the each one's specific methods. It adopts a systemic approach as informal modelling method, and UML languag
