Therefore, this study aimed to assess the importance of a proper value assessment tool in shifting to a circular built environment in Sri Lanka. Simultaneously, the absence of a proper methodology in assessing the economic aspects of circular economy principles is apparent in the built environment sector. However, environmental concerns are often disregarded in construction processes where the priority is given to the cost and economic return of construction applications. In addressing the shortcomings of the linear economy, the circular economy concept was introduced by prioritising the circular value streams of the resources which minimises resource extraction and waste generation. To encourage greater implementation of circular economy principles throughout the supply chain, a clear economic case is paramount, supported by metrics, tool.Īttribute to the rapid expansion of the built environment, excessive resource consumption and waste generation aligned with the corresponding linear economy practices have impacted the preservation of the ecosphere. The absence of incentives to design products and buildings for disassembly and reuse at their end of life is a significant challenge. The survey results indicate that while there is industrywide awareness of the concept, clients, designers and subcontractors are the least informed and this is a key challenge for greater adoption. Utilising the results from a survey and a follow-up workshop, this paper provides an analysis of an industrywide perspective of circular economy awareness, challenges and enablers. Little research on circular economy from a systems perspective including how new business models might enable materials to retain high residual values has been undertaken. The application of the concept of circular economy thinking in construction, which is in its infancy, has been largely limited to construction waste minimisation and recycling.
