Digital Transformation in Construction and Industry 4.0: A Systematic Literature Review

This systematic literature review examines the evolving landscape of digital transformation in the construction industry within the context of Industry 4.0. Drawing from a comprehensive analysis of 81 peer-reviewed publications from the Scopus database spanning 2014-2024, this study provides an in-depth exploration of research trends, technological innovations, and implementation challenges. The bibliometric analysis reveals a significant acceleration in research output since 2021, with particular emphasis on Building Information Modelling (BIM), Digital Twins, Cyber-Physical Systems, and emerging technologies such as Artificial Intelligence and Internet of Things. This review identifies critical research gaps and proposes future research directions to advance the digital transformation agenda in construction. The findings suggest that while technological adoption is increasing, significant research gaps persist terms of implementation at large-scale, economic justification, sustainability, systems integration, and human factors.
