AB  - Construction sites in general are in environments where noise, vibration, and dust including. Especially in renovation and demolition works, concrete cutting, drilling, and scraping require not only loud noise, vibration, and dust, but also long hours of reaction force from the workers to use the machinery. Robotization has progressed in recent years and the environment for workers is improving, but the working environment in general sites where robots are difficult to install remains a challenge. This study aims to develop a method to improve the noise and other working environments of refurbishment works. This paper describes the results of a feasibility study on a laser scraping method to reduce noise in the renovation of infrastructure facilities around residential suburban areas. The results show that thin cement adhering to the rebar can be removed by the low power laser. Furthermore, a comparison of the noise level with conventional methods on site confirmed the superiority of laser scraping. This result indicates, in terms of lean construction, will reduce waste and improve the quality of the site.
