Information Sharing Barriers of Construction Projects Toward Circular Economy: Review and Framework Development

The construction industry is transitioning towards the circular economy, an approach that effectively reduces the industry’s environmental impact and promotes sustainability. However, realising the circular economy goal requires adequate information sharing among stakeholders and across the building lifecycle stages. This research examines the barriers that impede the information-sharing process in construction projects for the circular economy. This research adopts the framework of the information-sharing process, which suggests four essential components: context, content, people, and media. This study systematically searches and analyses the literature to identify and classify the information sharing barriers in the circular economy context, as well as their interaction. This study also conducts a case study to validate the information barrier framework and the findings. The findings suggest that information barriers are interlinked and require comprehensive solutions from the aspects of technology, organisation, and people, instead of single-aspect solutions. As this study provides insights into the systemic complexities of how information flows within the circular economy implementation system, it consequently contributes to the improvement of sustainable construction practices.
