Rockfall Gallery Mingèr
Martina (Graubunden), Switzerland
Reduction of stripping time by 50 % due to real-time monitoring
The 240 m long gallery Mingèr in Switzerland has been built to protect the main traffic route in the Engadine high valley from rockfall events. Due to the need to speed up construction time, our client decided to use #Concremote to monitor early age compressive strength. By using Concremote cable sensors, our customer was able to reduce stripping time by half and construction could be completed five weeks earlier than expected.
Challenges:
- Completion of site work before winter time
- No experience with Concremote by the Graubunden Civil Engineering Office
Customer requirements:
- Reduction of the required 2 weeks stripping time to 1 week in order to complete site work before winter time
- Close cooperation with the Graubunden Civil Engineering Office
Concremote solution:
- Calibration of the concrete mix
- Concremote sensors for measuring compressive strength development in the tunnel slab
Time savings
Reduction of stripping time by 50 %, which lead to five weeks earlier completion
Cost reduction
Cost savings of 40.000 CHF due to earlier completion
