Modelling information flow during the conceptual and schematic stages of building design

This paper reports on recent research the aim of which was to study, model and simulate the information flow at the conceptual and schematic stages of building design. The development of a generic model of the conceptual and schematic design process for buildings is described. This model comprising design tasks and their information requirements was produced using data flow diagrams. Examples from several levels of the model are provided. Details are then given as to how the model may be used to assist the management of the design process both directly and by providing primary data for other tools and techniques. Industry feedback on the data modelling and these tools and techniques is then discussed. It is concluded that it is only by a better understanding of the flow of information among project participants that the management of design may be improved, and that although the generic data flow model provides immediate benefits to design managers these can be enhanced greatly by the use of the model as a primary data source for other tools and techniques including the design structure matrix and simulation.
