Sammanfattning
The purpose of this master thesis is to understand the current practice of Construction and Demolition Waste Management (CDWM) in the case area of a Swedish construction site. In addition, this paper aims to comprehend how Building Information Modelling (BIM) could support CDWM in the case area. This paper presents a case area of Swedish construction industry, and the results are based on observation, semi-structured interviews, and questionnaires. The current practice of case area’s CDWM includes on-site sorting, reuse, recycling, Just-in-time delivery (JIT), using prefabricated construction materials and color-coded waste containers. The practice of the CDWM mainly focused on sorting and recycling. The information regarding CDWM was shared among project stakeholders by using brochures, presentation, meeting, and information board. In addition, the contractor and subcontractors have a contract that stated who is responsible to take care of the waste on site. The use of BIM has been given attention in the current literature to support CDWM. BIM has not been used for CDWM in the case study. However, the case study’s company has an optimistic view about how BIM could support CDWM. Additionally, there is positive effort to implement BIM for CDWM for future projects at the company level. If BIM is used for case area’s CDWM, it could support the CDWM in many ways, such as minimizing CDW through design validation, providing material information regarding waste, and quantifying the generation of waste before construction or demolition. To bring change and improvement in the current practices of case area’s CDWM, there should be an education, workshop, and training regarding the concept of CDWM, waste management strategies and benefits of BIM in managing CDW to construction project participants. This, in turn, can help the case study’s firm and the general public to attain environmental, social and economic benefit from CDWM.
