Opening of the trench Elstermühlgraben, Construction phase 3.1 between Lessing and Thomasiusstraße

The partial construction section 3.1 of the opening of the trench Elstermühlgraben is limited in the upper current by the Lessingstraße and in the lower current by the Thomasiusstraße. The length of the section without the bridge structure is approx. 85 m. In addition to the actual trench to be opened (trench wall as an overlapping bored pile wall with front shell and facing brickwork), the building section also includes the traffic area Stich Thomasiusstraße as well as the redesign of the adjoining outdoor installations including lighting. The extension in the dead end is carried out as a cantilever.
Since the building project is located in the urban area, numerous supply and disposal lines run in the locality. Particularly in the area of the planned bridge in the Thomasiusstrasse, this means that the existing line stock (electricity, gas, district heating, sewage, drinking water, railway cable, communication and city lighting) has been laid out from the road cross-section during construction, the supply has to be secured in time and the media stock has to be integrated into the new bridge cross-section.
