Abstract: An effective planning is required to overcome cost over-run and time over-run problems in construction which could be achieved with the help of lean concept. The aim of lean is to maximize the value, in other words minimizing the wastes. Last Planner System(LPS) is one such lean concept developed in order to improve the project performance by reducing the inefficiencies faced in construction project. The objective of this paper to present the results obtained from implementing the Last Planner System in the construction of an apartment project. A list of constraints have been found out during constraint analysis and various remedial measures have been suggested for look ahead planning. Based on number of occurrences of constraints, root cause analysis was done to determine the causes for variation in Percentage of Plan Completed(PPC). The effectiveness and reliability of the project was found to be increased about 75% after implementation of Last Planner System(LPS). A list of success factors and barriers for improvement of project performance have also been listed.
Keywords: Last Planner System, Look Ahead Planning, Constraint Analysis, Root Cause Analysis, Percentage of Plan Completed.
