Description of the project:
The flood protection measures of the 2nd Rhone correction no longer provided sufficient protection. This was clearly demonstrated by the floods in 2000. The 3rd Rhone correction pursued 3 objectives: Flood protection, environmental protection and socio-economic concerns. Well over 60,000 tons of stones, combined with various fleeces, mats and plants, were used to protect the banks in Lot 3b/7b.
Requirements:
- Work in the water area (hydraulic engineering)
- Short construction time
- Up to 20 machines in use
