ESTIMATING THE CONSTRUCTION INDUSTRY'S USE OF BUILDING INFORMATION MODELLING (BIM) TECHNOLOGY FOR WASTE PREVENTION: IDENTIFYING CRITICAL STAKEHOLDER EXPECTATIONS

Abstract

The necessity of utilizing Building Information Modelling (BIM) to reduce Construction and Demolition Waste (CDW) is well-documented; however, the majority of the current CDW administration tools do not yet possess BIM functionality. Consequently, this investigation evaluates stakeholders' expectations regarding the potential application of BIM in the administration of CDW. Qualitative Focus Group Interviews (FGIs) were conducted with professionals who are familiar with the use of BIM to understand their expectations on the use of BIM for CDW management after a review of extant literature to assess the limitations of existing CDW management tools. The 22 elements derived from the qualitative data analysis were subsequently formulated into a questionnaire survey. The exploratory factor analysis of the responses identifies five principal categories of BIM expectations for CDW management: (i) BIM-facilitated collaboration for waste management, (ii) waste-oriented design processes and solutions, (iii) waste assessment throughout the building lifecycle, (iv) advanced technologies for waste intelligence and analytics, and (v) enhanced documentation for waste management. Evaluating these factor categories is essential for addressing stakeholder requirements for the application of BIM in CDW management. The aforementioned characteristics are critical for the introduction and acceptance of BIM-based tools and techniques in CDW management within the construction sector.
