Abstract

The need for proper and reliable planning is essential for project success. Capacity planning has received good attention in the construction community but few metrics exist to assess its performance. Since it is impossible to improve what cannot be measured, the goal of this paper is to introduce new capacity planning metrics that will help visualize and understand the current state of capacity planning on construction projects. Is there an overloading or under loading of resources? The new metrics developed in this research, will attempt to help in assessing the state of equilibrium in choosing the weekly load of tasks to match the existing capacity, or at least, to minimize the gap between the two as much as possible. These new metrics, in theory, will achieve the goal of informing planners and last planners about the status of load vs. capacity, the matching between the two, and the reliability of capacity planning on a project.

Keywords

Last Planner SystemTM, lean construction, planning and scheduling, capacity planning, capacity planning metrics, matching load to capacity.
