Abstract: The execution of construction technology projects generates substantial construction waste, both site-based and non-site-based, posing significant environmental and economic challenges worldwide. This paper explores a proactive approach to minimizing construction waste by controlling its causes during the pre-construction phase by integrating Building Information Modeling (BIM) and Lean Construction principles. Key pre-construction activities such as cost estimation, scheduling, constructability reviews, value engineering, procurement, and contracting are analyzed for their potential to reduce waste. Two scenarios - Existing Waste Management Strategies and Waste-Effective Site Management Practices are assessed using quantitative metrics and system dynamics modeling. The proposed technique employs eight causal loop diagrams, reflecting expert insights into waste reduction strategies, and is implemented using AnyLogic software with a stock-flow system dynamics model. Validation is achieved through a real-world case study, demonstrating the technique's applicability and effectiveness in minimizing construction waste during the pre-construction phase. The findings highlight the dynamic buildup of critical variables influencing waste generation and provide a framework for evaluating and implementing optimal waste reduction strategies. This research underscores the potential of BIM and Lean Construction to drive sustainable waste management practices in construction technology projects, contributing to enhanced efficiency and environmental stewardship.
