Los 1 Umspannwerk

The documents do not explicitly state the contract start date, end date, or total duration. However, there is a mention of a "Bauzeitenplan" (construction schedule) which indicates that there are phases and milestones, including adherence to specified "Abschaltfenster" (shutdown windows) and designated "Pufferzeiten" (buffer times). The project also involves interfaces between different lots, specifically Lot 1, Lot 2 (overhead line construction), and Lot 3 (construction cable deployment), requiring coordination of shutdown windows with overhead line construction and the construction cable.

The core scope of work for this tender is divided into three main lots, primarily involving construction services related to 110-kV electrical infrastructure in Mainz, Germany.

Lot 1 (Los 1) focuses on the modification of the Hechtsheim substation's 110-kV system.

Lot 2 (Los 2) involves the new construction, reinforcement, modification, and dismantling of masts and circuits, including corrosion protection, for the 110-kV overhead line systems between Bretzenheim-Hechtsheim and Hechtsheim-Laubenheim. This is necessary to significantly increase the transmission capacity of these lines, which have reached their limits.

Lot 3 (Los 3) covers the provision, rental, laying, operation, and dismantling of a temporary construction cable. This temporary cable is essential to ensure continuous operation of the Gass-Saar-Laub-rot circuit during the renewal work on the 110-kV overhead lines in the Hechtsheim substation area.

Across these lots, the work also includes the treatment of customer-provided components, managing deviations in provision schedules to avoid downtime, and coordinating interfaces between the different lots (Lot 2 and Lot 3; Lot 1 and Lot 3) regarding shutdown windows and deployment cables. A confidentiality agreement is required for the execution of the contract.
