Germany – Transformer substation – 2026_MA7_UW Leinefelde - Herstellung Ingenieurbauwerke, Verkehrsanlagen u. Freianlagen

The contracting authority for the project is the TEN Thüringer Energienetze GmbH & Co. KG. This is a regional distribution network operator. The Thüringer Energienetze GmbH & Co. KG plans to demolish and rebuild the substation in Leinefelde. It is planned to completely restructure the entire site in two construction phases, first the eastern part and later the western part. The complete disconnection system of the UW Leinefelde, including the associated substructure, is to be newly constructed. The "Civil Engineering" lot includes the construction of the civil engineering structures, traffic facilities and outdoor facilities for the entire substation. The following components of the new substation are to be produced, among others: - individual foundations and shafts (9 portal foundations, approx. 150 small foundations for equipment tables, approx. 10 lightning protection foundations, foundations for video surveillance, 2 transformer foundations, approx. 15 cable pulling shafts, 1 E-spool foundation) - works roads, paths and areas (asphalt areas, gravel areas, paved areas) - outdoor facilities (landscaping, fence system) - various cable duct trenches, protective pipe trenches and drainage pipes. The most important points summarised include, among others, the following services: - earthworks - prefabricated foundations - concrete and reinforced concrete works - drainage channel works - road construction works - landscaping works - steel construction works to a limited extent. Explicitly not included are the primary and secondary works (equipment installation, cable pulling and connection works). The construction site consists of the area of the existing 110-kV switchgear. The entire system will be converted during ongoing operations, and the construction work and the primary and secondary installations will be carried out sequentially, so that the construction of the new system will take place in two construction phases. Planned start of execution: 01.03.2027
