This paper proposes a framework for incorporating direct field labor hours and costs into an overall production strategy centered on Takt Time Planning (TTP) and the Last Planner® System (LPS). An integrated tracking tool, vPlanner Production Tracker, has been developed to associate labor information with production activities utilizing the same database. The association of field labor hours including budgeted, estimated, and actual with production activities provides an early indicator of risk on projects. The proposed framework improves the consistency and efficiency by which the information is created and maintained so that the system can be scaled to support large projects that span multiple years. This is done to shorten the cycle time between monthly financial forecasting and field labor utilization. The goal is to improve the effectiveness of identifying and mitigating risks of field labor overruns and also the realization of savings opportunities due to improved field labor utilization. The paper outlines the improved workflow processes and presents an analysis of the data collected over several months from a pilot project.
