Detailed design of building projects is a complex multidisciplinary process highly dependent upon effective aggregation of individual designs to produce a coherent set of final design documents. Throughout the detailed design process, changes are frequently introduced and need to be properly managed among the various members of the design team. This paper presents an information model for storing design information, recording design rationale, and managing design changes. The proposed model is built around a central library of generalized building components that can be used to describe a complete building project hierarchy. Each component allows the designer to store desired performance criteria and related design rationale. Each component is also sensitive to its own changes and automatically communicates such changes to affected parties through preset communication paths. The model, as such, provides improved design coordination and control over changes, thus helping to increase the consistency and productivity of the overall design process. Conceptual details of the model are described in this paper, and model implementation into a collaborative design system is presented in a companion paper.
