21. Develop a New Revit Plug-in Enabling Building Components-Based Construction and Renovation Waste Quantification: An Australia Study

Construction and demolition (C&D) waste is one of the most significant waste streams. Waste generation quantification provides the fundamental information for CD waste management. Without understanding the waste type and amount, it would be impossible to propose strategies to reduce and recycle the waste. Compared to construction waste, renovation waste received much less attention. BIM emerges as a potential solution to incorporate waste management considerations into the design from the beginning of projects, but limited studies apply BIM to improve CD waste management activities. This study aims to propose a prototype Revit-plugin enabling automated waste quantification at the early design stage. Based on available Revit models and rational assumptions, the plugin can estimate both the waste generated at the construction stage, and generated at the operational stage due to material replacement in renovations. It provides waste information enabling architects to optimise material selection at the early design stage thereby reducing waste generation at the later construction and operation stage.
