IFC Support for Model-based Scheduling

Abstract:Model-based scheduling is about linking information from three yet separated domains; (1) architectural design, (2) construction scheduling and (3) cost management & quantity take-off. It thus will benefit from the Building Information Modeling (BIM) approach followed by the international buildingSMART initiative and its product the IFC data model specification. On the basis of a novel rule-based linking approach, which is shortly explained in the beginning, the paper provides an overview of the work that has been done to apply the linking approach in conjunction with the IFC 2x3 release and available IFC-enabled design applications. The paper gives insights into the capabilities but also the gaps of IFC. However, the paper is not going into technical details, which are provided in a separate, freely available discussion paper. Instead it shows the way from the requirements definitions, to the gap analysis, suggested extensions and prototype implementations, namely the Scheduling Assistant and the IFC-interface plug-in for MS Project. It finally discusses the current status of our developments and gives an outlook for further developments within the European Research and Development project InPro, an Integrated Project under the 6th framework program that has supported this work.
