Method for Designing Macro and Micro Layouts for Storage and Temporary Facilities in Residential Projects Based on Takt Planning

Logistics is considered a key element for the successful adoption of takt planning. However, there are few practical studies that demonstrate how the issue of material storage should be approached. This topic becomes more relevant when considering that takt planning, as well as other lean-based methodologies, has a greater focus on reducing inventories. Therefore, this paper presents a method for designing macro and micro storage layouts in residential construction projects to support takt planning implementation. Using the design science research methodology, the study relies on the application of two-dimensional and three-dimensional cells to represent storage areas, supported by estimated data from a case study and secondary data of similar projects. The primary goal of the method is to optimize space usage in alignment with takt demands, thereby reducing waste and promoting production efficiency. The results highlight the method's accuracy in determining the occupancy rates of different storage areas for the various materials required to meet the project’s takt demand. As recommendations for future research, the study emphasizes the integration of digital tools, such as BIM, to facilitate spatial visualization and the exploration of generic algorithms for layout optimization.
