Current Status and Future Research Trends of Construction Labor Productivity Monitoring: A Bibliometric Review

Construction labor productivity (CLP) is a critical measure of efficiency in the construction industry. This bibliometric review comprehensively analyzes global research trends in CLP monitoring over the past 56 years. The review identifies the top journals, authors, and nations contributing to this field and highlights a significant increase in publications since 2000. The co-authorship bibliometric map illustrates how different nations collaborate in research, with Europe and Asia being the most engaged regions in the study of CLP monitoring. The author keyword co-occurrence analysis indicated the need for more consistent and reliable measurements of CLP in the field. Furthermore, the review highlights the importance of factors such as occupational health and safety, change orders, and the adoption of lean construction principles and innovative technologies for monitoring and improving CLP. Finally, we evaluated the characteristics of different modeling approaches utilized in CLP monitoring studies, considering factors such as data availability, the complexity of relationships, and the required expertise. This study highlights the need for real-time and transparent CLP monitoring methods. Overall, this study contributes to the research field by offering insightful information on the current state of CLP monitoring and proposing potential future directions for research.
