SerdB will carry out a vibration control study during and after the construction of section A, first line of the Luxembourg tramway. This mission was commissioned by TSO.
The service includes the measures before and after the paving
SerdB brings its know-how by performing an acoustic study within the framework of the extension of the school of music of Saint Sébastien sur Loire, project directed by the Atelier Vignault x Faure.
The study is carried out in the rehearsal rooms for amplified music (with modular reverberation), the auditorium (with the constructive principle of "box in the box" and modular reverberation) as well as the recording studio and controlled acoustic diffusion).
Saint Etienne Metropole plans to extend it's Tramway network for 5km between the station Chateaucreux and pôle d’échange de Terrasse.
After the first preliminary study carried out by SerdB, Saint Etienne metropole mandated SerdB on the whole extension concerned.
SerdB won a new order to carry out a vibration control campaign for the tracks deployed on the extension of the Algiers metro line. This mission was commissioned by GMAC.
The service includes vibration mitigation measures with the impact hammer along the future line.
It relates to sites with floating slab tracks as well as sites with elastomeric under sleeper pads.
SerdB shared its engineering expertise in the field of vibration in transport infrastructure during a seminar on innovative practices held at the Keran Group’s in Nantes. Companies such as SEMITAN, GROUPE LACROIX and ZENBUS were also involved in these exchanges.
The CCML2 consortium, composed by Dragados and FCC (Spain), Salini Impregilo (Italy) and COSAPI (Peru), commissioned serdB to carry out preliminary measures for the construction of the second line of the Lima metro.
The study consisted of a series of noise and vibration measurements at the exterior and at the foot of the dwellings to determine current levels.
The measurements have been focused on particular buildings considered to be sensitive (Parroquia de Carmen de la Legua, Palacio de Justicia and the water tower of Sedapal.).
SerdB updated the impact assessment in the framework of the development zone of the commune of Fouillet in Le Mans, for the company CENOVIA (Economic Development Agency of Le Mans Métropole.)
The service included Three phases:
- Noise measurement in the current state,
- Acoustic modeling,
- Study of scenarios.
AIRBUS (Nantes) has entrusted serdB with the study and monitoring of it's workshops that are most exposed to noise.
Several configurations have been observed among which, the loading and unloading operations of Beluga, a modified version of an A300-600 for the transport of aircraft parts.
INGEROP awarded serdB for vibro-acoustic study for the Lima metro line 1 (Peru).
The study consisted of simulations with the software dBtrack© and the vibratory impact linked to the construction of a viaduct at the nearby hospital of Rocca Fernández Essalud.
This study included:
- Measures to characterize the rolling stock
- Measures of soil transmissibility
- Measurements of vibration noise at the foot of the hospital Rocca Fernández Essalud and in front of the most sensitive devices
- A simulation of the site
- The search for solutions to reduce the impact of the future viaduc
SerdB has won the vibration monitoring mission for the demolition of buildings near the future Grand Paris Express station in Chelles (Paris-France).
This mission consist of verify in real time from a remote station that the vibration levels generated by the demolition site meet the thresholds imposed by the SNCF to preserve the integrity of the rail infrastructure.
