This study introduces a Building Information Modeling (BIM) system for accurate construction and demolition (C&D) waste prediction. The system aids contractors in planning waste management strategies and optimizing recycling efforts.
Area of Science:
- Environmental Science
- Civil Engineering
- Construction Management
Background:
- Growing volume of construction and demolition (C&D) waste in urban areas necessitates effective management.
- Current tools for quantitative waste prediction from demolition and renovation (D&R) projects are insufficient.
- Hong Kong faces significant challenges with D&R waste disposal, impacting landfill capacity and environmental policies.
Purpose of the Study:
- To develop a Building Information Modeling (BIM) based system for accurate estimation and planning of D&R waste.
- To address the research gap in convenient and precise waste estimation tools for the AEC industry.
- To support government waste management policies, such as charging schemes, through reliable data.
Main Methods:
- Developed a BIM-based system to extract material and volume data from digital building models.
- Integrated extracted information for detailed waste estimation and planning, including recycling and reuse considerations.
- Incorporated prediction of logistical needs (e.g., pick-up trucks) and disposal costs.
Main Results:
- The system successfully extracts relevant data from BIM models for waste quantification.
- Waste recycling and reuse opportunities are identified, enhancing efficiency.
- Predictions for logistical requirements and disposal fees provide advance alerts for project planning.
Conclusions:
- The BIM-based system offers a novel solution for D&R waste estimation and planning.
- The system can improve waste management efficiency, support policy implementation, and facilitate project control.
- Future adoption of BIM technology will enable broader application of this system across various projects.
