N2 - Although the construction sector is one of the least digitized sectors, the last decade has been a period that some qualify as the 4th industrial revolution, notably with the adoption of Building Information Modelling (BIM). However, the construction industry is still one of the most resource-intensive sectors, generating Megatons of waste every year. To decrease the impact of the construction on the environment, authorities are getting interested in adopting a circular economy (CE) approach, including servitization. Although there is an emulsion around the circular economy approach, organisational tools to help construction practitioners to move to a CE approach are dramatically lacking. The purpose of the paper is to develop a BIM-based trans-scalar theoretical framework to support practitioners in their understanding and the implementation of the CE approach. The trans-scalar theoretical framework is established with data extracted from a research portfolio fuelled by three main databases, Scopus, RIBA (Royal Institute of British Architects) Plan of Work and BIM standards. First, the RIBA framework and the information delivery cycle were adjusted to incorporate the sustainable end-of-life, as a phase in the CE context. Based on theoretical foundations, the main contribution of this paper is the trans-scalar theoretical framework developing and clarifying what are the main asset lifecycle phases (including the end-of-life), their related stakeholders, and the interplays between them, in the UK context. The paper also organizes holistically two scales, the asset lifecycle phases and the material flow, whether new or recovered, in the context of BIM and CE. Some future areas of research are presented, including how the BIM-based trans-scalar theoretical framework could be improved with inputs from construction experts.
