Abstract

Throughout the last few decades, a slow shift from the Critical Path Method to other, flow-focused scheduling methods has occurred in the industry. However, they have not yet been widely implemented by construction companies. This case study was conducted on a private data center project on a large site in which the project team has applied Takt time, pull planning, and location-based scheduling (i.e., Takt planning). The case study takes into consideration the roofing schedules for five buildings constructed over a span of three years and compares their total roofing task duration before and after the implementation of these techniques. The analysis has shown that a focus on flow and implementation of Takt planning on a large data center project decreases the overall duration of roofing construction tasks. This case study serves as a support for the transition from the traditional Critical Path Method to Takt planning or a flow-based approach since it has effectively decreased total roofing duration in this project.
