| Abstract |
IFC is a de facto standard of integrated building model in AEC/FM industry, which is growing in its international uses. In this paper, a pilot research to examine the capabilities of IFC model for quantity takeoff is presented. Three different types of subsets of the IFC model by categorization of quantity takeoff work are identified. A quantity takeoff system based on the subsets has been implemented. When an IFC instance file created by a CAD system is imported, instances are put into a spatial hierarchy by a project browser. Quantity takeoff is executed for an object selected from the hierarchy, the result being presented in a relational table. This research proves that IFC model can be a base for AEC integration. Comparison with previous works as well as future works to enhance model applicabilities are presented. |
