In 1971, the Principality of Monaco agreed to a €30 m development project on the richest part of Monte Carlo’s gold coast: the Complexe Immobilier des Spelugues. The complex was built over the Boulevard Louis II road on 15 metre concrete columns, with its hotel, convention centre and apartments overlooking the Mediterranean Sea. The Lower Corniche tunnel is amongst the most iconic lengths of track in the world of Formula 1 motor racing.
Four decades on, land scarcity led the Principality to expand into the sea once again, with the development of a new 6-hectare district, l’Anse du Portier. Construction included:
In order to manage the risk of disruption or damage to the Spelugues complex, an accurate and reliable monitoring system was needed.
Regional Surveying experts, Toposud first contacted Geomesure, Senceive French distributor, for technical advice.
They wanted to continuously monitor the beams and columns without the unsightly cables and limitations of a fixed optical system.
They chose the FM3N-IX FlatMesh 3 Triaxial Tilt Sensor Node because it offered:
The small battery-powered nodes and solar powered battery were discreetly installed on the structure without requiring power/data cabling or heavy anti-theft protection and can operate for up to 15 years without re-visiting site. A Senceive cellular gateway connected to the local network enabled all stakeholders to access structural data at any time of day, regardless of their location.
The system was configured to send text or email alerts in the event of any limit breaches to more than 25 people in 9 organisations.
Benefits of the Senceive wireless solution include enhanced health and safety and significant cost savings on installation, maintenance and site access.
