This paper describes the contractor’s approach to manage noise from construction site. At preliminary design stage, construction activities and methods are analysed in order to anticipate noise from construction work. This analysis is useful to choose judicious equipment localisation, to limit noise propagation and to organize noisy operation. The approach is based on a tree step analysis. A noise climate assessment of the area and an analysis of all equipment on site are the first step of this study. Then, the second step deals with the choice of the critical construction phases depending on the number of source, their sound power level, their activity and their position relatively to the noise receivers. Generally, a first estimation of noise at the plant site boundary is realised with analytical formula to determined critical phases. The last step of this analysis is the noise map calculations in order to quantify and visualize noise around the site from all contributing sources at a given construction phase. In addition, acoustic mitigation measures used on BOUYGUES TP construction site will be presented.
