Technical data management systems on large building construction projects

Our proposed solution is to enable partners of a construction project to share all the technical data produced and handled, during the building production process by building an information system through the use of Internet technology. The system links distributed databases and allows building partners to access remotely and manipulate specific information. This paper covers the information structure model based on building construction knowledge and the access to user-relevant information, we focus more widely on data access through the help of adaptable interfaces. These interfaces are built dynamically based on a user profile and the current stage of the building´s life cycle. It consists of 3D representations of the building as well as data that is associated to each graphical entities (example: Walls, Slabs, Windows and Beams). This project is been sponsored by Nemetschek France (subsidiary company of Nemetschek A.G., AEC CAD software leader), and SNCF (French railway public company).
