Grand Paris Line 15 South
Paris, France
Time savings of 22 hours per cycle thanks to real-time data.
The biggest urban project currently under way in Europe is part of the Grand Paris Express project. A consortium, led by Bouygues Travaux Publics, is currently working on batch T2A of Line 15 South. For this challenging project with complex geological formations and construction of structures under very heavy water loads and operational train lines, our customers decided to speed up the cycles by using #Concremote to monitor early age compressive strength. By using Concremote cable sensors, the users were able to strip formwork in 26 hours instead of 48 hours and thus save a lot of time.
Challenges
- Speed up the cycles as much as possible in the execution of the galleries
- Particular working environment dozens of meters underground and without GSM network
Customer requirements
- Required early strength for stripping 8 N/mm² and movement of the tunnel formwork carriage when reaching the target value
Concremote solution
- 2x Concremote cable sensor 2.0, 2x measuring cable with 3 measuring points = 6 measuring points per casting step
- Bluetooth feature inside the tunnel for the data transfer to the smartphone
Time savings
Time savings of 22 hours per cycle thanks to real-time data.
More Safety
Hard data for compliance conforming quality and strength thresholds.
