Light Detection and Ranging (LiDAR) technology has become a crucial tool in the construction industry, offering precise 3D data capture that addresses inaccuracies and provides accurate building information throughout various construction stages. Despite numerous studies on LiDAR applications, most reviews are isolated and lack a systematic, comprehensive analysis. This study fills that gap by combining scientometric and qualitative analysis to explore LiDAR research trends in construction. The process begins by collecting 671 relevant papers published over the past 15 years. The data is then quantitatively analysed to reveal key research trends. Lastly, the study qualitatively examines the implementation of LiDAR, focusing on three main areas: (1) the significant applications and benefits of LiDAR throughout the entire project life cycle, (2) the challenges and future directions of LiDAR technology organised by workflow stages, and (3) key future research directions aimed at enhancing accuracy, automation, and integrating technologies. This work provides insights for both researchers and practitioners, aiding understandings of the benefits and limitations of LiDAR technology, and offering direction for future research. Ultimately, the study contributes to the long-term management and practical application of LiDAR in the construction life cycle, promoting more intelligent, efficient, and sustainable infrastructure development.
