AB  - The Work Density Method (WDM) is used in takt planning for defining zones with equal workload. To date, this method has been applied mainly to building construction. This paper investigates the WDM’s applicability to equipment-driven processes in heavy civil engineering, specifically to the in-situ production of foundation piles for a highway infrastructure project. Two existing computer-based programs that support the application of the WDM, WoLZo and ViWoLZo, were used to find a suitable grid size based on data from a real-world project. The results show the potential of using the WDM (1) to define zones with equal workloads, given that pile groups are irregularly distributed over the construction site space, (2) to compare different scenarios based on work density as a metric (e.g., scenarios with different uses and sequencing of equipment), and (3) to derive a takt time and process duration when using multiple pieces of equipment that must coordinate their efforts and work in sync. Compared to the building construction application, the heavy civil engineering application reveals new requirements when using the WDM and takt planning in general, regarding the geometrical and logistical needs of equipment-driven operations that constrain how zones can be defined.
