PRODUCTIVITY ENHANCEMENT AND WASTE MINIMIZATION USING LEAN, SUSTAINABLE AND 5-S TECHNIQUES IN CONSTRUCTION INDUSTRY

Abstract

Construction industry is one of the significant and largest industry on global level and also it is a most important part of economy. It has potential to make a positive impact on sustainable and lean construction development. Lean construction focuses on lowering costs by eliminating waste, innovating by involving people, and structuring the workplace to be more efficient. While implementing lean concepts necessitates reevaluating current construction procedures and methods, new tools are also required. Additionally, lean, which primarily focuses on minimizing the environmental impact of construction, may have an impact on sustainability in addition to improving project time and cost performance. The lean methodology aims to reduce waste in this process. Which is typically divided into seven categories: overproduction, waiting time, transportation, extra procedures, inventory movements, faults and the operators lack of participation in generating process improvement ideas. As a result, lean-based tools have been developed and effectively used in both straightforward and intricate building projects. Lean construction projects are typically less expensive, safer, quicker to complete, easier to manage, and of higher quality
