A Study on the Establishment of Demolition Waste DB System by BIM-Based Building Materials

Recently, BIM (Building Information Modeling) became mandatory in Korea, and BIM started to be implemented in construction area. It is a design tool for maximizing the efficiency of design, construction, and maintenance throughout the entire lifecycle, but there are not many studies about the demolition wastes (DW) in the demolition stage. This study gathered basic data concerning the development of a database of DW disposed in the demolition stage using BIM-based building material database. For this, a BIM software, ARCHICAD, and construction material categories of the item list system of the PPS (Public Procurement Service) were analyzed to select major building materials. Based on the analysis, the disposal routes were analyzed considering the characteristics of DW. The database of DW was developed by examining the disposal routes of 52 major construction materials selected according to the characteristics of each material during demolition and selecting 7 major DW.
