Inszenierungsanlagen Einleitbauwerk Hambach - Generalplanung Bauwerke

The contract timeline includes several key phases and milestones. The contractor is expected to begin work within 10 working days after the contract is awarded. Immediately after contract award, the contractor should start with the in-depth study of the feasibility study, supplementary basic evaluation, and preliminary design planning.

Key milestones and phases are as follows:

• The draft design (Entwurfsplanung) is to be completed by the second quarter of 2027.
• The execution planning (Ausführungsplanung) is to be completed by the fourth quarter of 2027.
• The preparation for the tender (Vorbereitung der Vergabe) is to be concluded by the first quarter of 2028.
• Construction is scheduled to commence before mid-2028.
• The construction measure is to be finalized by the end of 2029.

The processing period (Ende Bearbeitungszeitraum), subject to approval, is indicated around Q4 2029.

For specific project components:

• Bermenbalkon: Planning and implementation for all necessary trades are foreseen until 2029, with a second implementation phase extending until 2033, and a third phase until 2070.
• Kunstobjekt: Planning and production are to be completed by 2029 during the first implementation phase.

• Pflanzenkläranlage (plant-based wastewater treatment plant)
• Starkstromanlagen (heavy current systems/power installations)
• Wasseranlagen (water facilities)
• Modular-prefabricated construction
• Demountable construction
• Movable construction
• Systems for generating energy for electricity and heat from renewable sources
• Consideration of sustainability criteria
• Reduction of resource consumption
• Use of low-energy manufactured materials and renewable raw materials
• High recycling rate for water, heat, and primary raw materials for a circular, CO2-efficient development
• Avoidance of negative impacts on the local environment (microclimate, biodiversity)
• Sensible and conscious use of economic resources over the entire life cycle of the structure (including all follow-up costs in cost calculation)
• Regular consideration of possible follow-up costs of design and execution planning
• Resistant and adaptable concept to promote resilience and flexibly react to changing usage needs (reversible)
• Ensuring long-term value preservation by creating high-quality and mixed-use objects with high user acceptance
• Creation of technical and structural prerequisites for optimizing energy consumption, including compact construction
• Accessibility (Barrierefreiheit) during planning
• Object-wide, integrated construction sequence planning
• Preparation of documents for special technical test procedures
• Setting up and calculating life cycle costs
• Preparation of maintenance planning and organization
• Checking the deconstructibility for the modular design and shutdown of water supply during deconstruction
• Performing performance measurements and functional tests
• Gendersensible Sprache (gender-sensitive language) using a colon (e.g., Bürger:innen)
• Use of gender-neutral expressions and abstractions where possible
• Use of new German orthography according to Duden
• eVergabe NRW tendering platform
• No problematic load input on the pipes of the inlet structure by the info pavilion
• Underground drainage pipes must not be built over
• Foundations for the viewing terrace must be built outside the pipe route and not on the pipes, requiring an overhanging/cantilevered solution
• Monitoring and action concept for structural supervision due to expected uneven settlements
• Pylons and associated foundations/anchorings must be placed laterally next to the inlet structure and possibly moved towards undisturbed ground
• Terrace elements should not run directly above the water cascades
• Technical inlet structure of RWE Power AG and its location and design are fixed prerequisites
• Staging must be planned independently but compatible with technical aspects and must not impair their functional/approval capability
• Observation of safety distances, possibly reduced in consultation with RWE Power AG and the mining authority
• Kippenboden (dump soil) is not suitable for load transfer for pile foundations
• Piles must tie deep into the grown, load-bearing rock and be able to absorb shear forces from rock movements
• Shallow foundations must be designed to accommodate load-independent settlements; special measures (e.g., vibratory compaction) may be necessary
