Abstract

Construction industry is considered one of the major and valuable industries for the economic development and growth in Egypt. An estimated 45% of the funds allocated for the national development plans in Egypt since 1981 were allocated to the construction sector and has been growing 20 % annually since 1980s. Having time and cost overruns is inevitable for project parties. Several Egyptian studies pointed at the planning process and lack coordination as being the main factor of these delays. Improvements to traditional planning were attempted by adopting philosophies like Theory of constrains, action theory, and lean philosophy benefiting from the development in the knowledge of production management in the manufacturing industry. This research utilizes the last planner system (LPS) based on lean construction principles developed by Ballard and Howell. The paper demonstrates two case studies in where Last Planner System is implemented on the construction of two identical steam turbines in parallel. The two projects were constructed by two different teams where the scope was the erection of the identical steam turbines. The Last planner system was attempted by the project controls team of the main contractor of the project, system was established in the 1st case study being constructed through self-execution by the main contractor, while the system failed to be implemented in the 2nd case study constructed by a subcontractor team.  The LPS performance metrics for the second case study were observed to be compared to the first case, the primary results from implementing the two cases include benefits gained, barriers of implementation observed, and comparison of results of implementation. LPS allowed for a more collaborative planning approach, it applies a system of close coordination with the people responsible for executing the plan, allowing them to discuss the plan and perform collaborative constrain analysis and progressively learn from the reasons of non-completion. The research highlights the various challenges in the application of the Last Planner System in the Egyptian Market with degrees of success, feasibility of implementation and lessons learnt.
