Head of Architectural Department, Mansoura University, Egypt Ahmed El tantawi Purpose – Information plays a significant role in managing construction projects. The architecture, engineering and construction (AEC) industry encounter a massive information exchange (IE) challenge. This study aims to develop a BIM-based stakeholder information exchange (IE) workflow scheme during the planning phase in smart construction megaprojects (SCMPs) that faces a massive IE challenge, especially during the COVID-19 pandemic. Designmethodologyapproach – To accomplish the above stated goal, a research approach including a literature analysis, case studies, and survey questions was developed. Based on the aforementioned, the study created a BIM-based IE workflow to simplify the implementation of IM in SCMPs. Findings – This study has yielded an extensive insight into the types of information exchange, difficulties, and ways to its hand over. In the context of CMPs, The research conceptualised BIM&SM synergy and proposed IE Workflow strategy during the planning phase in MCPs. However, IE needs to be planned from the beginning of the process, agreed upon between different parties, tested, and verified. Research limitations – The scope of this research is limited to the SCMPs during the planning phase. Practical implications – This study contributes to the developing body of knowledge addressing the application of BIM& IE synergy during the planning phase in SCMPs. The outcomes of this research will be beneficial for clients, contractors, and project managers, when taking into account in future plans. Originalityvalue – This study provides contributes to understanding information flow during the project planning phase and how to control it properly. Generally, the deliverables of this study could be utilized by professionals engageded in BIM and SM practices on SCMPs to enlightens and enhance information exchange and the utilization of the produced information throughout the entire process. 2022 2022 08 19 10.54216/IJBES.050101 https://www.americaspg.com/articleinfo/22/show/1210
