TUNNEL SAFETY ON THE A8 BETWEEN INTERLAKEN OST AND BRIENZ

Vibration monitoring during blasting work

As part of extensive safety measures on a section of the A8 motorway between Interlaken Ost and Brienz, rescue tunnels are being built alongside the Sengg, Chüebalm and Giessbach tunnels. The blasting work and the construction of interconnections to the existing tunnels is taking place with the road operating as normal.

GEOTEST Ltd. is supporting this construction work by monitoring vibration emmissions in the three tunnels and in houses located above the tunnel sites.

Autonomous individual measuring stations and numerous networked sensors have been installed. The measurement data is transmitted automatically by GSM and uploaded quickly to our online data portal. In addition, an active alarm system sends a warning SMS to all relevant parties as soon as certain vibration thresholds are exceeded.
