Identifying key parameters for BIM-based disassembly planning

Reuse of building systems and components has the potential of taking full advantage of the residual utility of building materials. In this matter, disassembly planning plays a critical role for retrieving reusable components in an optimized way. Unfortunately, the implementation of disassembly planning for buildings, at a component level, is still limited due to the lack of standardized methods and the lack of the definition of necessary characteristics (parameters) for building disassembly models. Therefore, the aim of this paper is to identify the necessary parameters for disassembly models and collate them into a framework. The approach in this study uses BIM as the main platform and graphic interface for managing the disassembly parameters for building components. First, the necessary information for building disassembly models is investigated. Then, the parameters for disassembly models are suggested and they are instrumented using BIM for a case study. The results of the enriched BIM disassembly model are verified according to the analytical solution for disassembly models for buildings.
