Integration of Building Information Modelling to Promote Circular Economy Principles in the Sri Lankan Construction Industry

The construction industry is a major contributor to resource consumption, construction and demolition waste, and greenhouse gas emissions, making the transition towards circular economy (CE) practices essential for sustainable development. This study investigates the potential of integrating Building Information Modelling (BIM) with circular economy principles to promote resource efficiency and sustainable construction practices in the Sri Lankan construction industry. A qualitative research approach was adopted through a comprehensive review of recent literature, international case studies, and an assessment of BIM adoption and circular economy practices in Sri Lanka. The study examines current challenges in CE implementation, evaluates BIM’s role in supporting material tracking, life-cycle assessment, waste reduction, and extended product lifespan management, and assesses the country’s BIM readiness. The findings reveal that the adoption of circular economy principles in Sri Lanka is constrained by low BIM maturity, fragmented digital infrastructure, and the absence of standardized policies and regulatory frameworks. However, BIM demonstrates significant potential to enable circular construction by improving information management, enhancing collaboration among stakeholders, and supporting informed decision-making throughout the project life cycle. The study proposes a conceptual framework for integrating BIM with circular economy principles and concludes that strengthening digital capabilities, policy support, and industry collaboration is essential to accelerate the transition towards sustainable and circular construction in Sri Lanka.
