KW 1 - Neubau Betriebsgebäude L41 Gewerk Elektrotechnik

The contract is scheduled to begin on March 1, 2027. The service is to be completed by April 28, 2028. This results in a total duration of approximately 14 months and 28 days. The documents mention the possibility of "Einzelfristen" (individual deadlines) as contractual deadlines, but no specific individual milestones or phases are explicitly listed.

The core scope of work and statement of work summary for this tender, based on the provided documents, involves comprehensive electrical infrastructure upgrades and related services within the M4 building, focusing on Medium Voltage (MS) and Low Voltage (NS) systems.

Key areas of work and deliverables include:

• Medium Voltage Systems (Mittelspannungsanlagen): Installation and integration of medium voltage switchgear, distribution transformers, and other associated medium voltage components.
• Low Voltage Systems (Niederspannungsanlagen): Implementation of busbar distributors, the main low voltage distribution system, UPS distribution, general installation distribution, procurement of installation materials, control cabinets, and wall distributors for overvoltage protection (M43), along with other low voltage system components.
• Installation Systems (Installationsanlagen): Work related to raised floors in both medium voltage and low voltage rooms, laying systems, and the installation of various cables and lines.
• System-wide/Cross-system Positions (Anlagenübergreifende Positionen):
• Services (Dienstleistungen): Including coordination with other trades and operations for timely deliveries and service execution, especially for conversion steps.
• Documentation:
• Approval Documentation: Provision of single-line diagrams, system views, typical section drawings, typical ceiling penetrations, and layout plans.
• Execution Documentation (Workshop Planning): To be provided in paper form before commissioning and digitally (CD-ROM) within 21 days after delivery, including circuit manuals and operating instructions.
• As-built Documentation (Enddokumentation): Required within two weeks post-commissioning, delivered digitally (Eplan P8 format on CD-ROM) and in paper form. This extensive documentation must include an index, installer confirmation, acceptance and commissioning protocols, all-pole circuit diagrams, customer application/program files, operating instructions for all delivered equipment, various test protocols (switchgear, transformers, protection devices, thermographic inspection), conformity declarations, data sheets, CE declaration for the complete system, and the integration of the entire scope (switchgear, cable trays, transformers) into original AutoCAD plans according to client specifications.
• Instruction of Operating Personnel: Training of the client's operating personnel by a commissioning engineer.
• Various Construction Measures (Diverse Baumaßnahmen):
• Dismantling of Existing Systems (Rückbau Bestandsanlagen M40): Removal of existing medium voltage switchgear (G1M1000), low voltage main distribution (G1N1100), and two existing transformers (G1M1000UT001 and -T002).
• Conversion of MV Cable Tray in the Collector: Widening the medium voltage cable tray from 300mm to 600mm, involving the replacement of cantilevers and cable tray sections, requiring close operational coordination due to necessary temporary de-energization of MV cables.
• Participation in Expert Inspection: Readiness of the contractor for expert acceptance of the completed medium voltage and low voltage switchgear in accordance with VDE regulations and BGV A3. The contractor is responsible for costs associated with additional inspections due to significant defects and must provide sufficient personnel for the acceptance process.
