Design Criteria Modeling – Use of Ontology-Based Algorithmic Modeling to Represent Architectural Design Criteria at the Conceptual Design Stage
Abstract. Building Information Modeling (BIM) applications have gradually replaced CAD as a means of solving information integration problems among different disciplines within the AEC (architecture, engineering, and construction) industry. However, the world's first BIM claim revealed the critical problem of information loss when the mechanical, electrical, & plumbing engineering (MEP) contractor ran out room in a ceiling plenum. If BIM can be used to present critical criteria, such as the maximum height of an MEP installation, then it is not necessary to remind the contractor to retain sufficient ceiling height. BIM applications encourage architects to model every detail of a building in order to foresee and resolve constructability issues in advance by means of visualization. BIM applications are based on the product modeling theory and methodology proposed by Eastman, which deals with buildings as products in an effort to boost productivity and constructability. Unfortunately, not all critical design information, such as minimal clearance of MEP installations and other design criteria, can be represented in the visualization of the final building products. The problem of losing critical information in BIM not only causes communication issues among different disciplines, but also marginalizes the roles of architects in the AEC industry.
