Automated design of prefabricated building

The paper describes a knowledge-based system for the detailed design of prefabricated building. The system employs a comprehensive approach which integrates different design aspects, architectural, structural and technological. The system receives, as an input, a preliminary architectural design of the building to be erected, adjusts it to a modular grid, indicates the location of structured supports, breaks down the floors and walls into elements to be prefabricated and finally produces detailed drawings of the elements and their cost estimate. The premise of the system, its operation and the structure of its knowledge are described.
