Project description:
- Lot 2, project 410450: construction work for roadway renewal (km 22.540 to 22.931, length approx. 391 m): As part of the FbE project, the entire track superstructure (rails, sleepers, ballast) will be replaced. The track drainage (PSS layer and drainage pipe) and the existing cable block will also be renewed and used as a new service route.
- Lot 3, project 390014: retaining wall construction work (km 22.120 to 22.540, length approx. 420 m): As part of the retaining wall project, the entire track superstructure will also be replaced. To make room for the reinforcement work on the uphill retaining wall, the track must be moved downhill. This requires the construction of a leaning bridge. A wall head extension will be partially implemented on the downhill side in line with the FbE project. In the 2021 construction season, reinforcement work will then be carried out on the retaining wall, consisting of extensive anchor drilling and in-situ concrete work.
Requirements:
- Complicated logistics as a result of restricted access routes and handling areas
- Work under railroad operation with limited space
- Two-shift operation (night and day work)
