Review on 5's Tools for Lean Construction

Civil Engineering

5s is a basic foundation of lean manufacturing systems. It is a tool for cleaning, sorting, organizing and providing the necessary groundwork for work piece improvement. This paper dealt with the implementation of 5s methodology in the small scale industry. By following the 5s methodology, it shows significant improvements to safety, productivity, efficiency and housekeeping. The improvements before and after 5s implementation is shown by pictures in the paper. It also intends to build a stronger work ethic within the management and workers who would be expected to continue the good practices. Value stream mapping is used to first map the current state used to identify sources of waste and to identify lean tools to eliminate this waste. The future state map is then developed for a system with lean tools applied to it. VSM is a pencil and paper visualization tool that shows the flow of material and information as a product makes its way through the value stream. VSM serves as a starting point to help management, engineers, suppliers, and customers recognize waste and its sources. This paper demonstrates the implementation of lean philosophy through layout modification.
