This paper describes the prototype expert system COKE (Construction Knowledge Expert) that was recently developed at the Center for Integrated Facility Engineering (CIFE) at Stanford University. COKE provides feedback on the constructability of the structural design of a reinforced concrete building structure. With the help of constructability heuristics, COKE reasons about a geometrical and topological product model of a designed facility. This paper addresses the three main challenges for the development of such a system: formalization and representation of constructability knowledge, development of a product model to represent project data. and integration of the product model with the knowledge.
