Design for construction, mining and environment

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.

Project management included the following services:

• Clarification of target conflicts
• Information to the employer about the project handling, including the scheduling of important decisions
• Verification of the planning results of the experts involved in hydraulic engineering (structural engineering, hydraulic engineering, freestanding) with interface coordination bridge construction
• Conformity test to the general conditions of the planning permission
• Control of the implementation documents, including the list of services and the participation in the preparation of the tender documents
• Development of the complete construction schedule

Coordination of services included the following:

• Creation of a coordinated line stock (actual condition) after previous screening, possibly required data conversion as well as digitization and layer processing
• Creation of a coordinated management plan for the relocation during the construction period, both regarding the size of the construction site as well as the necessary temporal classification in coordination with the responsible management bodies and presentation in the construction phase-dependent plans
• Creation of a coordinated management plan for the final state (PLAN state) after carrying out the water and bridge construction measures
• Identify the interface problems of all parties involved and participation in solution finding
