AB  - The construction industry has been struggling with inefficiencies and operational flow interruptions in traditional project delivery. In contrast, the Takt planning method is emerging as a lean alternative designed to create a robust and streamlined trade flow. Despite growing takt adoption, the granular effects of takt versus traditional construction of individual worker flow have not been explored. This study conducts a comparative analysis of two case studies, one using traditional methods and one using takt planning. Analysis is based on quantitative indoor positioning system (IPS) data from workers on both projects. The findings reveal notable differences in operational flow. The quantitative data suggests that the traditional environment indicates a "stop-and-work" workflow with high variability and weak coordination between workers. In contrast, the Takt environment shows a stable, rhythmic, and highly synchronized workflow. The indicated contrast in the worker movement patterns suggests the practical differences between the two methods.  This paper studies the effects of Takt on individual workers and movement-related waste compared to the traditional approach. The findings suggest that takt production is associated with reduced movement-related waste and more controlled operational flow.
