The core scope of work and statement of work for this tender primarily involve comprehensive documentation, construction, and coordination tasks.

Core Scope of Work and Statement of Work Summary:

• Documentation and Planning: This includes creating and updating existing site plans based on revision documents, ensuring their conformity with the actual site, and delivering updated metadata lists. It also encompasses incorporating control results, considering remaining ground components, managing barcode numbers for new plans, and updating metadata with track and object links. The documentation is to be provided in both digital (view and source files) and multiple sets of paper formats. Further, it involves detailed project management documentation such as project orders, plans, organizational charts, milestone and framework schedules, reports, management summaries, risk analyses, and public relations. Preliminary and detailed planning phases, including feasibility studies, basic evaluations, preliminary designs, execution plans (with explanatory reports, drawings, stability proofs), fire protection concepts, sound reports, thermal insulation proofs, and environmental impact assessments, are also part of the scope.
• Coordination: Extensive coordination is required with the ARGE/construction company regarding deadlines and interfaces for civil engineering, cable, and electrical installation work, including excavation pits, cable routes, cable shafts, and blocking periods.
• Construction Activities: Specific construction tasks mentioned include preparing and compacting the subgrade for the entire foundation slab, ensuring specified flatness and compaction levels. Cable civil engineering work involves the installation of various sizes of cable shafts made from precast concrete elements, complete with bottom plates and cable entry elements, and closing unused openings.
• Proof Securing and Expert Assessments: The tender requires documenting existing fastenings and edgings of terrain, roads, paths, and squares within the construction area through inspections, written protocols, and extensive photographic documentation. An independent expert office must conduct condition assessments and expert opinions for securing evidence in buildings and structures located near the foundation site. This includes detailed documentation in text and images, with submissions before construction begins and a final inspection.
• Permits and Approvals: Obtaining building permits, internal corporate approvals (UiG), and individual case approvals (ZiE) is a critical part of the work.
• Cost and Financial Planning: Preparation of cost compilations, cost overviews, cost calculations, negotiation cost estimates, amortization calculations, draft agreements, construction time and financing plans, and economic efficiency calculations.
• Compliance and Standards: Adherence to DB standards and regulations, including specific guidelines for DB approvals, framework contracts, lightning protection risk management, classification of electrical systems in hazardous areas, and layout plans for electrical infrastructure like transformer stations, cable routes, and heating systems for trains and switches.
