A conceptual framework to manage circular economy knowledge in construction projects

Circular Economy (CE) implementation in the construction industry has gained wider attention worldwide due to its ability to minimise the negative impacts of construction industry practices. However, gaps in CE knowledge have hindered CE implementation in the construction industry. Although the necessity of Knowledge Management (KM) for CE transition has been raised in numerous studies, existing literature has a dearth of CE KM studies, which is further limited in the construction context. Thus, this research aims to develop a conceptual framework to manage CE knowledge in construction projects by investigating required CE knowledge for construction professionals. A comprehensive literature review was undertaken to achieve this aim by analysing the literature using manual content analysis. The findings of this research highlight the overlaying impact of knowledge and KM on financial, market, technology, policy, and culture-related enablers and barriers of CE implementation in the construction industry. Furthermore, the potential of knowledge on addressing context and concept-related barriers to implementing CE was discussed, and a bespoke KM cycle with seven steps has been established, highlighting the importance of the KM cycle for CE KM rather than using the KM process. Finally, a conceptual framework for CE KM of the construction industry has been developed, revealing a shell view of these concepts. These findings will be beneficial for construction practitioners to i). understand areas of knowledge to be improved, and ii). identify KM actions to initiate improvements to ensure the implementation of CE principles.
