This study addresses these gaps by adopting a structured literature review and thematic synthesis to explore CE principles in building construction management. The study is guided by the following research questions: - What are the key circular economy principles relevant to building construction management? - How can these principles be applied across the different phases of the building construction process? - What are the major barriers and enablers influencing the adoption of CE in building projects? - How can building construction management contribute to advancing sustainability through circular practices at the lifecycle level? The aim of this study is to provide a structured overview of CE in building construction management, clarifying its applications, challenges, and opportunities. The ultimate targets are threefold: to synthesize and categorize CE principles, to demonstrate their relevance across lifecycle phases, and to identify barriers and enablers shaping adoption. By reframing CE as a management-oriented strategy rather than a purely technical concern, this chapter contributes to both scholarship and practice. It argues that building construction management holds a decisive role in operationalizing circularity, enabling the sector to reduce environmental impacts while delivering long term value.
