Abstract: Generating and maintaining construction schedules from architectural drawings is vital to both construction and design professionals. Automating the task requires combining a CAD system with knowledge-based programming and database techniques. A prototype system, called BUILDER, is presented for the domain of routine interior office construction. BUILDER incorporates a knowledge representation scheme that enables the interplay of the drawing and the construction knowledge base. The features of the drawing are extracted and represented in a semantic network of frames. A forward chaining rule based expert system processes the semantic network of frames to produce a project network. The project network is represented in an object oriented style that can readily admit functional extension. The knowledge intensive planning paradigm, developed in BUILDER, is found to be appropriate both in principle and because of the routine nature of the domain.
