Abstract: Lean construction practices are becoming prevalent in the construction industry. However, the success and methodology of implementation is varied. This paper outlines a functioning methodology of best practices to implement elements of the Last Planner System® (LPS) from the Lean Construction Institute in conjunction with critical path method (CPM) scheduling. This methodology realizes the benefits of both systems for project management.

In this paper the authors will describe the process for integrating the information derived in pull planning sessions into a baseline schedule to provide not only the high-level plan for the job, but also the detailed level execution planning for production monitoring. They will delve in to managing the CPM relationships and activity IDs to maintain schedule integrity for baseline comparison for future evaluation.

They will demonstrate the use of 6-week look ahead schedules and weekly work plans based on the updated schedule. The review of the execution of those weekly work plans based on the planned percent complete and the reasons for variance against the plan. The trending of these variances will be used to identify and mitigate on-going production issues and strive for continuous improvement.
