A Bibliometric Review of the Synergy Between Building Information Modeling and Integrated Project Delivery in the AEC Industry

The Architecture, Engineering, and Construction (AEC) industry continues to face persistent inefficiencies and fragmentation that limit collaboration and innovation. The convergence of Integrated Project Delivery (IPD) and Building Information Modeling (BIM) offers a strategic response to these challenges. This study conducts a comprehensive bibliometric review to examine the intellectual, thematic, and collaborative evolution of IPD-BIM research. Drawing on 276 peer-reviewed journal articles published between 2000 and 2025 and analyzed using VOSviewer, the study maps publication trends, co-authorship networks, and thematic clusters. The findings reveal a pronounced growth in scholarly output after 2015, driven by government procurement mandates, institutional reforms, and digital transformation policies, particularly in the United States and Australia. Keyword and citation analyses reveal five interconnected clusters – digital delivery (BIM-IPD), management, procurement, performance, and technology. Recent emphasis shifts toward integration, interoperability, and lifecycle value. Emerging topics (5D BIM, blockchain, VR) signal movement from concept demonstrations to system-level deployment and transparent, data-driven collaborative delivery. The results demonstrate a maturing research ecosystem anchored in strong North-South asymmetries but with increasing global participation. The study contributes an interpretive framework that links technological innovation with collaborative governance, offering actionable insights for policymakers, educators, and practitioners in construction delivery systems.
