The construction sector plays a significant role in resource consumption and waste generation, making the transition to a circular economy (CE) imperative for sustainability in this sector. This paper focuses on developing a framework for implementing CE principles in the construction sector, guided by expert opinions and insights. The main objective of this study was to enhance existing theoretical frameworks by incorporating feedback from construction experts to improve practical utility and applicability in real-world construction practices. By addressing key areas for enhancement, the revised framework facilitates the adoption of CE practices throughout the asset lifecycle, considering buildings from cradle to cradle. This research’s methodology involved a comprehensive literature review to identify gaps in current frameworks related to CE implementation in the construction sector. Unstructured interviews with twenty construction experts were conducted to gather insights and recommendations for framework improvement. Data analysis highlighted the importance of integrating CE principles at various stages of the asset lifecycle, such as design, construction, and end-of-life phases. The key recommendations from experts include incorporating sustainable approaches, aligning with BIM models, and considering whole-life design aspects to promote circularity in the construction sector. By incorporating expert feedback and industry insights, the framework aims to guide practitioners toward more sustainable and resource-efficient construction practices, contributing to the broader field of CE implementation in the built environment.
