Competency measures are increasingly becoming effective ways for construction organizations to measure their ability to deliver waste-efficient projects. Despite the ongoing efforts in achieving the goals of the circular economy through BIM adoption, there is still a paucity of studies on building information modeling (BIM) competencies for delivering waste-efficient building projects. This paper, therefore, aims to identify and investigate critical BIM competencies for delivering waste-efficient building projects in a circular economy. The study adopts a pluralistic approach, using a combination of the review of extant literature, focus group discussions and questionnaire survey. Analysis of the focus group discussion along with the result of the literature review revealed forty-three preliminary BIM competencies, which were subjected to rigorous statistical analyses. Four broad categories of BIM competencies for delivering waste-efficient building projects emerged from the analyses. These are project management-related, construction-related, procurement-related, and design-related BIM competencies. Construction firms could use the BIM competencies identified in this study to enhance the delivery of waste-efficient building projects as well as assess their BIM competency requirements at an individual and organizational level. •Construction projects constitutes significantly to waste generation and total landfill in the UK.•Building information modelling (BIM) is becoming the standard for delivering construction projects.•There is the need to identify the BIM competencies for delivering waste-efficient building projects.•The BIM competencies for delivering waste-efficient building projects were explored using pluralistic approach.•The BIM competencies identified could be used to enhance the delivery of waste-efficient building projects.
