Germany - OLA-Ern. Prien - Rottau, section 5703, km 25.0 - 30.8, construction supervision service

Description

OLA-Ern. Prien - Rottau, line 5703, km 25.0 - 30.8, construction supervision service
As part of the project, the overhead line system will be renewed on route 5703 from km 25.0 to 30.9. The reconstruction limits are the Prien station (km 25.0) and the Rottau transfer point (km 30.9).
Depending on the ground conditions, the type of foundation varies between in-situ concrete and driven pile or driven pipe foundations. According to the subsoil expertise, however, a large part of the renewal of the rail line can be carried out using driven pile foundations. The OL renewal is planned using new steel pylons (flat and angled pylons). The new catenary system will be built according to the Re 200 design. A railroad power line does not exist and will not be installed. In the course of the orienteering renewal, existing orienteering facilities will also be dismantled, whereby the old chainage, the old orienteering masts and the old orienteering mast foundations will be removed.
Due to a lack of space, angled masts with multi-track cantilevers will be erected on the left-hand side of the track between km 25.9 and 26.3. The line separations of the open switching section boundaries will also be renewed in Prien station as part of this measure. The 15 kV and OSE cables in connection with the Prien junction renewal project will also be replaced when the switching section boundaries are renewed.
Construction supervisors for the following trades are required for the measure described:
- Overhead line
- 50 Hz/ EEA
- Superstructure/ KIB
- SiGeKo
