ABSTRACT
The research project is part of the priority program 1103 “Networkbased Co-operative Planning Processes in Structural Engineering” which is promoted by the German Research Foundation. The planning and observance of a time schedule is one important task for process modelling. For time scheduling the critical path methods can be used. The product model includes information on the building elements and their relations within the context of the whole building. The planning process of a building is subdivided into three sub models: an organisation structure, a building structure and a process structure. The consistency of these three sub models is provided by process management based on methods of graph theory. The building structure and the process structure are represented by hierarchical bipartite graphs. These hierarchical structures support the dynamical aspects of cooperated planning processes in building engineering. The building structure covers the planning states of all building elements including the references to the product model.
