- Resumen
Lean Construction is regarded as an innovative approach of management for various types of projects in the field of construction. As much as it is currently applied in some countries, its expansion is inevitable, for better overall results are obtained and the projects’ objectives are met more precisely. Despite the fact that Lean Construction offers solutions to many problems occurring under the traditional management approach known as the Project Management (PM), the scope of its application is not as promising. Countries where Lean Construction is minimally applied include the United States of America and the United Kingdom besides other countries in Europe and Latin America. However, it is still not applied to a more exhaustive extent in these countries and is completely missing in many others around the world. This study primarily focuses on the application of Lean Construction to Infrastructure, specifically road projects; investigating Lean Construction solutions to the time wastes. Through conducting a case study research, this work focuses on investigating the impact of applying Last Planner System as a Lean Construction tool on the elimination of Non-Value Added (NVA) activities, that is, wastes in a highway project in Cairo, Egypt. This study includes a State of Art on both Project Management approach and Lean Construction. The study applies a comparative approach between the application of Project Management approach and Lean Construction in road projects. Hence, the researcher conducted different simulations of the studied road project, taking into account the two approaches (Project Management and Lean Construction), then obtaining the simulations results. Two parameters are used as comparison criteria: Percentage Plan Complete (PPC) and Percentage Activity Waste (PAW). The later (PAW) is a new parameter introduced by the researcher to investigate its results before/after applying the Lean Construction tools. Findings of the study support the research hypothesis that the application of Lean Construction approach to road projects enhances productivity through eliminating time-related wastes and decreasing the project duration. This research supports the argument that road projects can benefit greatly from the application of Lean Construction instead of the traditional approach.
