abstract={Takt planning and takt control are increasingly applied in lean construction to stabilize workflow and improve project performance. However, empirical evidence explaining how performance improvements emerge over time remains limited. This study investigates how schedule performance improvements develop in a takt-based production system through an empirical case of a twin-tower project executed, focusing specifically on structural works. The research questions are how takt planning contributes to initial schedule performance improvements and how deviations between planned and realized production during execution contribute to further performance improvement over time. The project represents the first implementation of takt planning and takt control by PT PP (Persero) Tbk. Using a case-study approach, the study distinguishes performance gains through takt planning and additional improvements during execution through takt control. Our results show that takt planning significantly reduced planned project duration and stabilized workflow. Further schedule gains shown through deviations between planned and realization enabled learning and localized corrective actions. By comparing performance outcomes at the whole project level and zone level, this study demonstrates that early performance losses reflected a learning and adaptation process. Meanwhile, repeated workflows and continuous control supported improved coordination, predictability, and faster delivery over time. It enables the systematic incorporation of lessons learned from the first tower into the second tower in the near future. },
