Integrated planning of buildings based on computer models in project communication systems
The increasing demands in building and civil engineering – with regard to the growing amount of legal requirements and the needs of a flexible usage of the building - requires an optimisation of all processes during the planning and construction phases. This aim can be only reached by transferring of innovative information and communication technologies in the field of cooperation of all partners in a building project. In this article the enhancement of the existing planning processes based on an improved information management is introduced. Since the late 90ies the availability of hardware and software infrastructures for a networkbased cooperation, e.g. email, in small and middle-sized companies increased the problems of an unstructured communication in the planning and construction processes. These problems have not been solved by the usage of the upcoming project communication systems either, which are often used as a simple medium for data transfer. Because of the easy way of distributing documents to all planning partners a huge amount of files and subsequent versions can be stored so that the planners often have to scope with an information overflow. The underlying hierarchical structures based on simple files stored in tree views are not sufficient for an adequate representation of the different specific views of the planners and the management of relationships between the three information domains building structure, costs and time schedules. ..
