Building Information Modelling (BIM) as a new evolutionary way of working methodology for the building industry enables collaboration and improved communication, underpinned by the digital technologies, which unlock more efficient methods of designing, delivering and maintaining physical built assets. BIM uptake is picking up lately but mainly concentrating on design and construction with less emphasis on facilities management. Claims in the literature are asserting that the BIM use for FM requires Integrated BIM use, classified as maturity Level 3, with a life-cycle perspective. However, this book explains hands-on case study research of BIM modelling and its use for FM tasks (soft and hard tasks) as if BIM modelling for a new building to show that use of BIM can be practically usable for facilities management simply via simply BIM modelling. With the approach in the book about BIM use for FM, the authors encourage researchers and practitioners to explore practicing BIM at the modelling level, which is believed that the BIM use for FM and BIM modelling for existing buildings will be intensified.
