Object description:
The existing drainage of the NEAT Steineji bridges runs into an infiltration basin, which is located in the project perimeter of the Steineji storage area and parking spaces project. For this reason, the existing infiltration basin must be relocated. New pipes and shafts will be used to drain the NRLA bridges into a temporary infiltration basin that is no longer located within the project perimeter of the A9 highway.
Special requirements:
- Increased accuracy of the gradient of the pipes
- Short construction time
