The core scope of work for this tender primarily involves the demolition and disposal of an existing 400 kVA stationary emergency power system ("Netzersatzanlage") and its associated components, followed by the delivery and installation of a new 400 kVA emergency power system in a container.

The key activities and deliverables include:

• Demolition and Disposal of Existing System: This encompasses the complete dismantling, removal, and environmentally sound disposal of the existing 400 kVA stationary emergency power system located in the basement of the Central Tower. This includes all related tank, pipe, and cable systems, electrical components, distribution systems, control systems, the exhaust system, and the existing storage tank system. Specific items for demolition include the NEA control cabinet, fuel tanks, oil tanks, fuel lines, starter batteries, pipe systems, steel structures, cable systems, cable trays, empty conduits, cable ducts, electrical installation devices (switches, sockets, junction boxes, luminaires), general electrical devices (electric heaters, actuators, silencers), and approximately 1,000 liters of diesel in the day tank and 17.5 cubic meters in the storage tank. The demolition process also requires unfastening, disconnecting, disassembling as needed, transport, and professional disposal, including the provision of disposal certificates.
• Installation of New Emergency Power System: This involves the delivery and assembly of a new 400 kVA emergency power system housed within a container, situated separately from the Central Tower. It includes connecting the energy and control cables already installed on-site within the container and conducting necessary test operations with a new low-voltage main distribution system provided by the client.
• Site Setup: Establishing and clearing the construction site, and maintaining the site setup for all services throughout the performance period.
• AwSV Compliance: Performing all necessary services to meet the requirements of the Ordinance on Facilities for Handling Water-Hazardous Substances (AwSV) for the diesel-powered emergency power system and its associated tank system. This includes reviewing AwSV requirements, identifying notification and approval obligations, preparing required documentation (plant description, layout, installation, and piping plans), coordinating with the manufacturer, submitting notifications to the water authority, processing inquiries, and providing all submitted documents and official feedback to the client in digital and editable formats.
• Commissioning, Documentation, and Acceptance:
• Inbetriebnahme (Commissioning): This involves submitting plans and technical documents for approval, providing factory certificates for dynamic and static load behavior, functional testing and adjustment, commissioning and load testing, instruction, and handover of documentation to the client. It also includes performing a 1:1 test of all GA data points and acceptance with the client, specialist engineers, and approved experts.
• Bestandsdokumentation (As-built documentation): Creation of comprehensive as-built documentation for all sections and systems of the emergency power system, including electrical, fire protection, operating and maintenance manuals, circuit diagrams, installation plans, EC Declaration of Conformity, installer certificate, and approval notices for tank systems. This documentation must be submitted in both paper (2 copies) and digital (1 copy in PDF and editable formats) forms, adhering to Bundeswehr infrastructure guidelines.
• Abnahmen (Acceptance): This includes accompanying expert inspections for electrical systems, coordination, and securing acceptance from chimney sweeps according to 44. BImSchV, and AwSV registration.
• Additional Operator Training: Providing additional training for the operator on how to use the emergency power system under operating conditions at a separate appointment, including all incidental costs and protocol.
• Delivery and Installation of Specific Components for the New System: This involves the supply and operational connection of various components for the new containerized emergency power system, such as:
• Container with integrated sound insulation, fuel tanks, exhaust silencers, and, if necessary, soot filters.
• Starter battery, damping and mounting plates.
• Fuel tank, fill level monitoring, and pump system, overflow protection, and fuel lines.
• Air intake and exhaust louvers with motor activation, weather and bird protection grilles, and sound attenuators.
• Elastic duct connections and duct fittings.
• Capsule ear protectors, handheld spotlights with chargers, and various signs and notices.
• Operational fluids, including fuel with long-term stabilizer.
• Hours-based work: Provision of personnel for hours-based work, including specialists and helpers.
• Coordination: All necessary coordination with involved companies and local site supervision.
• Workplace: The services are to be performed at the Wehrtechnische Dienststelle für Luftfahrzeuge und Luftfahrtgerät der Bundeswehr (WTD 61) in 85077 Manching during working hours between 7 AM and 5 PM.The core scope of work for this tender involves the comprehensive demolition and disposal of an existing 400 kVA stationary emergency power system and its associated infrastructure. This includes the dismantling, removal, and environmentally compliant disposal of the emergency power system, all connected tank, pipe, and cable systems, electrical components, distribution and control systems, the exhaust system, and the storage tank system.

Following the demolition, the project requires the delivery and installation of a new 400 kVA emergency power system within a container, to be located separately from the Central Tower. This includes connecting site-installed energy and control cables within the container and conducting necessary test operations with a new low-voltage main distribution system provided by the client.

Key deliverables and services include:

• Demolition and Disposal: Complete uninstallation, removal, and disposal of the existing 400 kVA emergency power system, including its aggregate, diesel engine, day tank, load resistor connection box, control cabinets (power switch cabinet, control cabinet), air intake and exhaust culverts, exhaust system, tank lines, starter batteries, pipe and steel constructions, cable systems (energy cables, control lines, grounding lines, 230/400 V lines), laying systems (cable trays, empty conduits, cable ducts), electrical installation devices (switches, sockets, junction boxes, luminaires), general electrical equipment (electric heaters, actuators, silencers), and approximately 1,000 liters of diesel from the day tank and 17.5 cubic meters from the storage tank. This also includes professional disposal with documentation and site cleanup.
• Installation of New Containerized Emergency Power System: Delivery, assembly, and operational connection of a new 400 kVA emergency power system within a container.
• Site Establishment: Setup and clearing of the construction site for the entire duration of the project.
• AwSV Compliance: Ensuring compliance with the Ordinance on Facilities for Handling Water-Hazardous Substances (AwSV), including reviewing requirements, identifying notification and approval obligations, preparing all necessary documentation (plant description, layout, installation, and piping plans), coordination with manufacturers and authorities, submission of notifications, and processing inquiries until completion.
• Commissioning, Documentation, and Acceptance: This encompasses submitting technical documents, providing factory certificates for load behavior, functional testing, commissioning, load testing, operator training, handover of documentation, and performing 1:1 tests of all data points. It also includes acceptance by the client, specialist engineers, and authorized experts.
• As-Built Documentation: Creation of comprehensive as-built documentation for all parts of the emergency power system, including electrical and fire protection plans, operating and maintenance manuals, circuit diagrams, installation plans, EC Declarations of Conformity, installer certificates, and tank system approvals, provided in both paper and digital formats.
• Specific Component Delivery and Installation: Supplying and installing various components for the new system, such as starter batteries, damping and mounting plates, fuel tanks, fill level monitoring and pump systems, overflow protection, fuel lines, air intake and exhaust systems (louvers, weather and bird protection grilles, sound attenuators, duct connections), ear protection, handheld spotlights, and various safety signs.
