Identification and Analysis of Lean Techniques in Indian Metro Rail Projects

Lean construction is now being implemented by several construction industries all over the world to increase the productivity of the projects. While endeavoring to implement lean principles, the construction industry is facing several challenges to decrease the occurrence of complexity. Urban transportation is becoming increasingly important in India, and it has become a prerequisite for economic and social success. Among urban transportation, metro rail projects are regarded as one of the most significant construction projects. There have been various studies on the technical and economic analysis of metro rail projects. But there are only a few studies on the application of lean techniques in metro rail projects to decrease the impact of complexity. The purpose of this research is to study the application of lean techniques in metro rail projects to reduce complexity and propose a conceptual framework. This study provides knowledge on the management of a metro project using lean techniques to reduce the occurrence of complexity. This research can be used successfully in metro rail projects to reduce complexity and waste, and increase productivity. The research results would help different stakeholders to put lean theories into practice.
