Abstract: This paper presents a framework to enhance the design for prefabrication for the construction of a facility using the IFC model. The framework integrates architectural design with constructability analysis tools. The structural and architectural configuration for prefabrication is the focus of the framework. The system utilizes the dimensions, positions and spaces characterized in the 3D CAD to configure the structural and architectural elements of the building starting from the architectural design. It is based on the latest version 9 of the Autodesk Revit Structure which is IFC compliant. Traditional architectural design of each building contains structural components, non structural components, facade components, roof components, etc. Each category of components is configured based on three main criteria pertaining to space distribution, building structure and construction planning. The objective of this framework is determining the minimum number of prefabricated components which is derived from the minimum component designs while satisfying size limitation due to pre-fabrication process. Other rules pertaining to transportation and operations are also taken into account, such as prefabricated size and weight limitations due to transportation restriction, on-site assembly and lifting. The present proposed prefabrication system considers only the technical and functional aspects of the designed building. © Civil-Comp Press, 2009.
