This research investigates the impact of early facility management involvement on the effective utilization of building information modelling during the operation and maintenance phase. It looks at understanding the factors that encourage building owners to prioritize early facility manager engagement. This research also examined the role of facility managers when involved early in the process, including the stage in which FM should be involved, the additional knowledge and competencies to add value, the main tasks to perform and what barriers should be overcome to involve FM early. Lastly, this research defines the potential added value that early engagement has on the use of BIM in the operational phase. Recognizing that facility managers bear the ultimate responsibility for building management, this study explores how their early engagement can ensure BIM model align with operational needs, maximizing the technology’s benefits throughout a building’s lifespan. By examining the impact of early FM input, this research aims to provide actionable insights for facility managers to contribute to the BIM development process.
