The role of Building Information Modelling (BIM) in waste management deconstruction plan via 3D reconstruction model

The construction industry has adopted strategies to reduce waste through the circular economy approach. This involves designing buildings in a way that allows for easy disassembly and reuse of components, known as reversible buildings. By accurately estimating the type and amount of waste generated during deconstruction, effective waste management plans can be developed. However, the lack of standardized practices and incomplete information often pose challenges in implementing these strategies. This paper aims to provide a framework for creating 3D reconstruction models of buildings using Building Information Modeling (BIM). These models can assist in decision-making for waste management prior to demolition or deconstruction. In this study, 3D laser scanning technology is used to reconstruct buildings and create 3D models. BIM plays a role in identifying the type, specifications, and volume of building components. This data is then used to predict the volume of deconstruction waste, enabling the planning of waste transportation, fuel consumption, and carbon emissions. For model validation, a multi-story office building in Jakarta, Indonesia, is used as a case study. The simulation results demonstrate that the proposed framework can be applied and yield favorable outcomes in deconstruction planning.
