Building Information Modelling (BIM) plays a pivotal role in the digitization of facilities management (FM), fundamentally transforming the built environment sector. However, managing the change in organizations to successfully transition into a BIM-enabled FM system remains a significant challenge. To address this, this paper starts with a literature review of existing theories and practices of change management and digital transformation in the built environment sector. Based on the analysis of barriers and strategies identified in the literature review, a five-step roadmap for change management in BIM adoption is proposed. It includes establishing a change management team, conceptualizing the initiative, developing an implementation plan, managing the transition phase, and maintaining the change. The roadmap aims to guide organizations to effectively adopt BIM for FM, resulting in streamlined transition, enhanced operational efficiency, and improved asset performance. Further research is needed to validate the proposed roadmap and its potential for generalization to other sectors and countries.
