In Monaco, you can´t afford to gamble with vibrations
For Bureau Veritas, report generation and ease of use are essential
In Monaco distances are short and assets are precious. So when the famous principality decided to build a new museum and a car park between the Olympic swimming pool and a popular promenade – making room for three large electric transformers and moving the Grand Prix track a few meters –well, vibrations became a major concern.
The principality of Monaco assigned a leading international consultancy company, Bureau Veritas, to monitor vibrations throughout the project.
Mr. Patrice Arnoult is in charge of the project and responsible for all vibrations and noise issues at Bureau Veritas in France:
“Beyond meeting the client’s specifications, we were looking for a system that was easy to install and start up, but also easy to adapt to changing requirements over time.”
Six Sigicom V12 sensors were applied to or very close to the construction site, and eighteen INFRA C12 sensors to surrounding buildings. To solve a problem with insufficient GPRS reach in the basements of some buildings, these units were complemented with external antennas.
Daily vibration reports
If and when the set limits are exceeded, alarms are forwarded to Bureau Veritas’ consultants and to the main building contractor on site. People with the right authority can then halt the work immediately. Every working day, all vibration data are also compiled and analyzed in reports. This documentation is essential for settling any future disputes on liability, in case of vibration damages.
Throughout the four years construction period, activities in the immediate vicinity, with its luxury apartments, exclusive shops, an art gallery etcetera, will go on as usual.
The environment is also sensitive from another point-of-view: The sensors and any other equipment used must be very discreet, not to ruin the aesthetics of the architecture. The INFRA C12 geophones are very discreet and can be left in position even during the Formula 1 race.
The project was initiated mid 2015 and will be completed in 2019.
