“Our road and motorways network accounts for several hundreds km of urban roads and motorways. We pay particular attention to the smooth integration of these roads within their natural environment. Since 1990, we appreciate the unique capacity of A-Tech to design ad hoc noise reducing devices of all shapes, tunnels and tunnels exits. The numerous studies executed by A-Tech led to harmonious achievements, which performance has been successfully tested.”
Mr Biwer, Ingénieur première classe – Division Centrale de la Voirie
Since 1994, as a real precursor of the European regulations published in 2002, the Walloon region decided to implement an acoustic cadastre of its road and motorway network. Up to now, 450 sites have been studied, and we have created a specific process so that they can be automatically followed-up by the Administration. To succeed in this assignment, we have made use of our software MAP-3D® and we have created a specific methodology to classify the relevant sites.
In 1997, with 10 years of European experience in high speed trains and a worldwide reputation as expert in the area, we won the contract of the Seoul-Busan high speed train. The South Korean consortium entrusted us with the mission to study their network project, and to teach the Korean team to acoustic matters. We further achieved the detailed study of noise reducing devices the drawing of specifications and the definition of structural specificities, in partnership with TUC-Rail.
“As architects, we must harmonize aesthetics, comfort and ergonomic concerns while integrating elaborate techniques.
Our projects become every day more specific: meeting rooms for international gathering with simultaneous translation equipment, restaurants, video-conferences… Such a complexity requires a global approach at the very first stage of conception.
In every project executed in collaboration with A-Tech, we have been able to deliver extremely performing buildings on an acoustic view point, without giving in on our architectural choices”.
Dominique HARRIS, Architect
ADP recently upgraded its noise monitoring system for all Parisian airports. Concerned about the quality and the reliability of the environmental information broadcasted to the public, ADP has implemented a new system for which we have created a real time interface with radar data.
This interface enables a permanent and reliable access to all informations relating to aircraft trajectories around Orly and Roissy – Charles de Gaulle airports.
We have accomplished this mission within the very tight deadline imposed, with the total satisfaction of our customer.
