• After the order is placed, preparatory activities such as workshop and assembly planning, coordination with the network operator, and coordination of delivery dates and delivery are to commence.
• The actual execution date is contingent on the construction progress of construction phase 2 of the civil engineering measure and will be announced two to three weeks in advance.
• The contractor is expected to begin performance within 12 working days after receiving the client's request, which is anticipated by October 5, 2027.

The core scope of work and statement of work summary for this tender involves comprehensive planning, installation, and commissioning services for an electrical substation and associated infrastructure. Key areas include:

• Planning and Documentation: Detailed engineering and assembly planning (Werk- und Montageplanung) covering network topology, distribution cabinets, connection boxes, cable routes, and connection details. This includes creating assembly drawings, labeling plans, terminal plans, material lists, and parts lists. Coordination with electrical planners and other trades, incorporation of changes, and creation of revision documents are also required. All documentation must be delivered in verifiable form and digital formats (DWG, PDF).
• Electrical and Communication Infrastructure: Installation and connection of data and supply lines, including fiber optic (LWL) connections with patching. This involves the configuration and commissioning of network components, such as IP addressing, VLAN setup, and port assignments, along with functional testing of data connections. The work also covers the provision, bundling, laying, and connection of MS cables (e.g., NA2XS(F)2Y 1X70RM/16) including connection sleeves and accessories.
• Site Management and Project Coordination: Establishment and clearing of the construction site, provision of cable pulling equipment, and overall project management including material and personnel coordination, participation in construction meetings, defining preliminary services, monitoring and coordinating assembly teams, reviewing connection conditions, establishing schedules, and clarifying interfaces.
• Monitoring and Control Systems: Creation and parameterization of web-based overview displays for the electrical network within an energy and condition monitoring system. This includes a general overview of the electrical network structure, transformer station, low-voltage main distribution (NSHV Trafostation), energy flows, switching and operational states, measurement values, and alerts. Additionally, an energy, measurement value, and status dashboard must be created and parameterized.
• Transformer Installation: Delivery and installation of 20kV/0.4kV transformers, specifically 1000 KVA units, which must adhere to specific ecological design standards (e.g., EN 50588-1:2014-07 Stage 2).
• Earthing System: Installation of the earthing system for the station building, including deep electrodes.
• Pre-Acceptance Operation: Operation of the contractual facility or parts thereof prior to formal acceptance, including operation, monitoring, and necessary maintenance to ensure operational readiness and functionality, as well as troubleshooting.
