###### Abstract  
Building Information Modelling (BIM) has been extensively studied and applied within the AEC sector, particularly in design and construction. In recent years, Facility Management (FM) processes are becoming more digitalised, thus requiring effective BIM-FM integration. BIM adoption in many countries, such as the UK, Italy and Brazil, has been publicly driven. Generally, adoption was targeted at design and construction implementation, with little effort in framing public action for FM implementation. The lack of an integrated approach for BIM-FM implementation resulted in numerous bespoken implementation approaches that mimic the private sector and hinder knowledge exchange. Therefore, there is a need for assessing and amalgamating knowledge about BIM-FM for public organisations. This research aims to leverage knowledge about BIM-FM in the public domain by analysing and classifying articles published between 2010-2021. The research was carried out through a systematic review and comparative thematic analysis investigating the use of BIM for different public buildings (e.g., schools and hospitals) and the implementation for FM purposes. Research results outline prevalent trends and areas of research from three perspectives: people, process and technology. Results show an increasing number of publications about BIM-FM. However, the divide between BIM-FM for public and private organisations is unequal. BIM-FM research for public organisations is still limited and lacks standardisation. This state-of-the-art review makes an incremental contribution to knowledge by identifying progress, gaps and new industry directions on the subject matter.

It involves collecting data about assets from the earlier phases of the building life cycle, performing analysis and using them for decision support throughout the operations phase [2,4]. Hence, achieving asset operation efficiency through asset data availability is fundamental to reaching an improved total cost of ownership, especially for large and public buildings, where the range and complexity of the assets are more significant than for residential ones [5]. Therefore, BIM supporting lifecycle information management can unlock large economies of scale. Concerning BIM adoption, to the present day, greater scholarly attention has been paid to the design and construction phases. Notwithstanding long-term benefits, emphasis has been given to the immediately tangible outcomes from the earliest process stages of a building project [6, 7, 8, 9, 10]. Levels of BIM adoption have revealed that it has been used most extensively in the first phases, whereas adoption and use for facility management is still a new issue [11, 12], particularly in relation to its benefits to organisations (rather than projects). In addition, considering that the administration of public money differs from that of private organisations, the value proposition of BIM adoption (to a certain extent) is also different from that of private organisations. Therefore, BIM implementation differs in many aspects, such as training scalability. In other words, if the public sector is to provide training, how can training be achieved at such a large sector and who receives training first (i.e., hospitals, schools or other types of public infrastructure)? Such differences underpins the justification for further investigations. Then, regarding challenges for implementation, the lack of BIM-FM expertise among professionals and the lack of support in the form of guidance and standards contribute to the low adoption rates for BIM-FM implementation [13]. Furthermore, many public bodies at different levels have established BIM programs, set up BIM goals and implementation roadmaps and published BIM standards [7]. Therefore, as public actors, they perform a crucial role in leading and supporting the industry towards BIM implementation.
