Abstract

Construction industry has a fundamental role in the impact caused to the environment, both during construction and operation. In this research three Lean tools - Ishikawa Diagram, 5 whys, and A3 reports- were carry out at construction site during wall and floor ceramic installation. The aim was to investigate whether the application of Lean tools improved productivity in the activity execution, and measure the environmental benefits obtained. The research methodology included analysing video recordings of the activity execution, working groups with workers and management, and training for using Lean tools. From this, it was show that the principal perceived waste was rework and its cause was lack of control. Furthermore, it was prove that these Lean tools’ implementation reduces carbon dioxide emissions, for installing walls and floor ceramic, considering a reduction in the use of materials needed for the evaluated activity. In conclusion, Lean tools’ implementation allows reducing environmental impact by concentrating reduction efforts on the most important activity wastes.
