Randa Rockslide – In 1991 about 30 million cubic meters of rocks fell from a rock face near the village of Randa (10 km north of Zermatt).

At the Onnens Motorway A5, the cross-section of the tunnel consists of two concrete vaults. The length of the tunnel is 1230 m.
Structural monitoring of few section in the Lee Raw water tunnel in London.
The construction of the Champ Baly cut-and-cover tunnel served as a pilot project for the application of High Performance Concrete in Switzerland.
To optimise the support and confining structures in this area, SMARTEC SA was asked to install SOFO sensors to monitor the buttresses at the tunnel entrance and the concrete lining inside the tunnel.
Monitor the convergence and generally the structural behavior in one specific section of the tunnel where there are border conditions changes.
The utility of the instrumentation is to detect any cracking in the second concrete layer of the tube and monitor tunnel deformations during power plant service (when water is flowing through the tunnels).
The main aim of the monitoring in this project is to provide a distributed system able to increase knowledge on the structural behaviors.
