Today, Building Information Modeling (BIM) has been widely explored and embraced in more than sixty countries. Globally, BIM players in policy, technology and process fields are significantly contributing towards BIM research with several directions for improving the building design, construction and operation process. Our study is for critical assessment of the research on BIM in building’s project life cycle (PLC), with the aim of bringing together the present-day “body of knowledge” from global research outputs and delivering a comprehensive and collective perspective of BIM till date. BIM publications considered for analysis in this research are journal publications, conference proceedings, research reports, master’s and PhD thesis, etc. Through an extensive review of thousand BIM publications delivered from sixty-five countries, this study produces an outlook of BIM research, along with current understanding and practice in the area of BIM within global AECO Industry. A well-structured solid BIM literature review and well-defined knowledge of previous works together allow us to delivers an overview of global research trends in BIM. In this study we were able to identify the high, moderate and less researched BIM fields (i.e. the current researched directions for BIM) and model uses. BIM publications review in our research may be considered a scoping study, seeking to examine the extent and nature of the BIM research activities with several BIM directions.
