A Case Study on Implementation of Lean Tool in Indian Infra Project

India's construction industry is currently experiencing substantial delays, due to low productivity and inadequate labor management. Lean construction is a method that seeks to minimize waste and increase production. The goal is to examine how well the Lean methodology works for managing projects. Value stream mapping, a Lean tool in construction, plays a vital role in resolving this problem since it increases productivity. The non-value-added activities can be found using value stream mapping. By shortening the duration of these non-value-added activities, productivity can be increased. The value stream mapping Lean tool was utilized in a case study of pier cap building in a bridge construction project, and a potential gain in productivity was identified. The present state of the activities in the erection process was mapped first, followed by the preparation of the future state map of the activities after the non-value-adding jobs were eliminated.
