Interoperability of information systems is partially resolved due to many standards such as networks protocols, XML derived languages and object oriented programming. Nevertheless, semantic heterogeneity limits collaborative works and interoperability. Despite ontology and other semantic technics, the binding of heterogeneous information systems requires new technics of managing and displaying information according to the semantic representation of each stakeholder of the collaboration. In this paper we addressed the problem of merging geographical information systems and building information model. The way to achieve this goal must solve several heterogeneity problems due to the data life cycle, the data temporality, the binding between 2D geo-referenced modelling and 3D geometric models or problem of scalability for real-time 3D display from remote server for managing a real environment of several million m2. To bridge this gap, we present a new architecture based on a semantic multi-representation of heterogeneous information.
