Construction sector is evolving on regular basis with the technologies improving their productivity. Lean construction was first introduced by Toyota company in 1993 for production companies and later on it was implemented in construction sector. Lean model focuses on efficient use of manpower and machineries to eliminate waste. Value stream mapping (VSM) is a lean tool that helps us to visualize, analyze and improve all the steps involving in any activity of a construction project. Activities which are important, add value to the project. Whereas, some activities are considered as waste for not contributing in the productivity of the project. These activities constitute of almost 80-85% of all the activities in the construction projects. It shows the flow of both materials and information as they progress through the whole process. Literatures addressing VSM and the method of analysis were studied which lead to site investigations and sometimes survey conducting its use. Two projects were approached and five activities were monitored in total. Stopwatch was used to monitor all the activities and then the information was entered in the prepared observation sheet for further analysis. The motive of this paper is to map the current practice and then formulate the future map with the help of lean tools. So, the method of research was explanatory case study. The future state map objectified subsequent increase in percentage of value addition in activities Blockwork, Plasterwork, Slab-Reinforcement work, Slab-Shuttering work and Slab-Casting work up to 29.56%, 11.32%, 40.7%, 11.79% and 14.41% respectively. A considerable reduction in the cycle time of the above-mentioned activities states the implementation idea of this technique in all the construction project.
