    “Silent Building Site”: the White Paper that will make a big noise

    The publication of the Silence Chantier White Book is the culmination of a considerable research and innovation work, conducted in collaboration with Roland Cahen (teacher and researcher in sound design at the ENSCi) and the office of impedance engineering acousticians, for the Société du Grand Paris.

    Evaluated in January 2019, the “Silent Building Site” White Book is a great toolbox to limit noise pollution of public works. Now available to all players in the construction industry, this mine only needs to be exploited. “Silence Chantier” is a contribution to the reflection on the noise pollution of construction sites. It has been written by independent professionals, namely a teacher-researcher in sound design (Roland Cahen, ENSCI-Les Ateliers, accompanied by students from September to January), an acoustician specialized in construction sites (Bertrand Masson and cabinet Impedance) and a designer (Gaël Hiétin / ateliergh). The Société du Grand Paris has also made its contribution, by presenting the devices and methods deployed on its worksites, in particular on line 15 South where all the stations are under construction.

    TOOLBOX

    Our team supported its reflection on the innovations and devices deployed within the Grand Paris Express. Among the recommendations are the audio systems, such as the Lynx Cry, which attenuates the shrill beeps of construction machines when they fall back. Beyond this concrete example, the White Paper lists all the solutions against noise. generated by urban projects far beyond Île-de-France. There are even innovative devices found in other cities, with the London Crossrail or Noord-zuidijn in Amsterdam. The interest of the White Paper is that it deals with the issue of noise pollution in all its dimensions: technological, organizational, legal or political. It identifies avenues of innovation at each stage of noise propagation: at the source (noise-generating work equipment, for example), transmission and reception / perception by residents of the site. “We do not have a miracle solution, but we have tracks and we present them to you! “Immediately announce the authors of the book who review good practices and who do not hesitate to point out the” false good ideas “and” rumors “that they may have encountered over the years. their careers. Thus, contrary to popular belief, it is wrong to say that one gets used to noise or that the company that conducts the work makes the noise it wants.

    INCENTIVE TO CHANGE

    Gathering understandable texts, schemas and links to more technical content, their guide argues for an approach to the subject over time, each step of which is an incentive to change. A real action plan that involves the implementation of technical solutions, the declination of alternative methods when they are possible, a better sharing of responsibility between the contractors and the companies and finally by a support to the implementation of new equipment, less noisy. Among the ideas put forward is “Point Noises”, a system that encourages businesses to meet their noise commitments. And like a points license, if you lose too much, beware of the penalties. On the contrary, if companies respect them, they can be awarded the “Prix du silence” .This toolkit is aimed at the entire construction ecosystem in France: project owners, contractors, companies works, engineering offices, local authorities and local residents. It is part of a process of transparency and a permanent return of experiences: the largest infrastructure project in Europe, the Grand Paris Express knows that it is observed everywhere in the world and that it is a place of experiments for all actors of public works.
