Abstract
Demolition waste management is the process of managing, collecting, handling and disposing of waste in demolition projects. Significant effects on resource preservation, environment, and public health, and safety are the main concerns associated with demolition waste. Hence, lack of a sound decision making system for demolition waste management can negatively affect construction and demolition industry. Therefore, this study aimed to develop an integrated tool in order to assist decision making for demolition waste management. To achieve this target, overall review on the whole life cycle of demolition waste was conducted. In depth literature review and reliable interviews with experts have led to generation of a complete description of factors affecting waste management during demolition projects. Critical factors of demolition waste management were identified by considering risk assessment approach integrated with the Delphi method analysis. Next, critical factors affecting demolition waste management and different waste paths were assessed based on a consensus opinion from the experts’ panel. Analysis of the important data from the experts meeting session was conducted by using Analytic Network Process (ANP) Benefit, Opportunity, Cost and Risk (BOCR) model. ANP BOCR and Rating model have been used to rank the critical factors and demolition waste paths. To evaluate the developed model, the research used three case studies which were The Garden Premium Parking, Masjid AsySakirin and Putra Bus Station. The functionality of the model was evaluated by four evaluators. Conclusively, the result confirmed that the model satisfied 74.5% of the expectations. The developed model namely referred as Demolition Waste Management Model (DWMM) will enable the decision makers in a demolition project to systematically and semi-quantitatively identify, analyze and evaluate waste management factors. DWMM acts as information source that can be used by demolition contractors to identify and evaluate demolition waste related factors to be incorporated into the project design.
