The subject of this tender is the supply and installation of an overhead contact line system in the Haus-Berge-Straße area of ​​Essen (this is contract unit 4.10). Contract unit 4.10 "Overhead Contact Line System Haus-Berge-Straße" comprises the construction of an approximately 650-meter-long, double-track tram line, including the necessary overhead contact line system. The system will be constructed as a tensioned catenary overhead contact line with the contact wire suspended from masts using cross spans and cantilevers. The scope of work includes, in particular: I. Supply and installation of approximately 1,500 m of contact wire, II. Supply and installation of approximately 1,500 m of catenary wire, III. Supply and installation of approximately 30 single-track catenary cantilevers, IV. Supply and installation of 3 cross spans (catenary), V. Supply and installation of 8 tensioning springs (Tensorex), VI. Supply and installation of 3 mast switches including remote drives, VII. Dismantling of 2 temporary masts including foundations, VIII. Necessary assembly, fastening, cabling and wiring work, as well as testing, adjustment, readjustment and commissioning work, and IX. Necessary adaptations and connections to the existing overhead contact line system. The overhead contact line system is to be designed for a nominal voltage of 750 V DC (operating voltage approximately 825 V DC). The standard contact wire height is approximately 5.50 m above the top of the rail; the system height is approximately 1.80 m. The overhead contact line will be a tensioned catenary system. The work must be integrated into the construction sequence of the overall project and, in particular, into the concurrently carried out road, sewer, and track construction work. Continuous, uninterrupted construction access cannot be guaranteed. Therefore, the work must be carried out in sections and according to the specified construction phases. Construction will generally be carried out while maintaining private and public bus traffic.
