Abstract
According to the improvement of IT technology, an enhanced efficiency of management system in the construction industry is expected since a quotation system with BIM (Building Information Modeling) technique effectively estimates construction materials. For an enhanced efficiency of management system, related guidelines, standards, and manuals based on BIM are required, but the lack of this information causes difficulty to utilize in practice. In the paper, prior to the development of the manual that can be presented criteria and details of BIM-based quantity-takeoff, breakdown criteria of information breakdown structure which is the basis of the manual is suggested. Keywords- BIM, Information Breakdown Structure, Quantity-takeoff, Manual.
