ABSTRACT
This chapter explains about a conceptual model of building product in collaborative design and manufacturing environment, based on a systemic approach and formalised using unified modelling language language. It describes the building design and manufacturing context within actor’s interoperability. The chapter discusses the conceptual modelling as tool of interoperability, and draws on the proposals of a formal conceptual model. In spite of the several actors concerned with the building design and manufacturing, the building sector remains one the rare fields excluding tools and methods dedicated to collaborative work. The legal framework constitutes a kind of method which influences the production of the building. In other methods of design initially conceived for the industrial sector come to influence the building sector. Concurrent engineering is the normal evolution to which the building sector should evolve. Going beyond the actual cutting in the building design and manufacturing process means first of all the reconstitution of an informational continuity in the building life cycle.
