This tunnel comes after the Unstrut Viaduct, which is currently under construction (length: 2,668 metres, height: 50 metres).

A short cutting (length: 43 metres) provides access to two tunnel tubes, both of which are 2,082 metres long. At the east end they emerge into a cutting with a depth of 18 metres. The line climbs for 500 metres until it reaches ground level, where the next line construction lot starts.

The Osterberg Tunnel construction lot includes the two portals, the surface drainage system, roads alongside the track, emergency access roads and a retaining wall adjacent to the protected FFH area of the dry slopes by Steigra (Trockenhänge bei Steigra).

The 2,082-metre Osterberg Tunnel, which has two single-track tubes, is being constructed as a double-skin vault structure with an outer skin of shotcrete and a concrete vault inner skin by conventional means using explosives and excavators. The two skins are separated by an air cushion foil.

The tunnel cross-section is being excavated in sections: the upper section first followed by the two lower sections. The cross-passages are started soon after the upper section is excavated so as to keep the tunnel logistics for the excavation of the lower sections separate by crossing between the two tubes.

Successful project collaboration with EPLASS:

On this particular construction site over 250 people from different disciplines are employed. Furthermore, other designers, checking engineers, and geotechnical engineers are also involved in the project. By using EPLASS Professional all these project participants received access to all relevant documents.

By use of different workflows, both the preliminary as well as the construction phase processes, in addition to the structural analysis, are being reviewed digitally and approved for construction. Via a special interface, the federal railway authority is also involved in the project.

In addition to the design management via EPLASS Professional, the digital construction documentation is being archived within the EPLASS Correspondence document management system (DMS), and also the administration and review procedures of all claims are being processed within the EPLASS Claim Management module.
