ENTEGA AG - Erweiterung Heizwerk Babenhausen Luftwärmepumpe Kaisergärten Babenhausen Dekarbonisierungsschritt 1 Luftwärmepumpe Los 1: Planung Anlagentechnik zur Wärmegewinnung – Technische Ausrüstung gem. §§ 53 ff. i.V.m. Anlage 15 sowie der Technischen Anlagen(-bestandteile) im Außen /Freianlagenbereich ab der Leistungsphase 2 zur förderfähigen Transformation des Wärmenetzes.

The contract timeline is characterized by a series of defined milestones and a phased approach. The performance/planning commencement is to occur at the latest within two weeks following the commissioning of the respective service level/phase or optional special service.

Key milestones and their latest completion dates are as follows:

• Submission/completion of the preliminary design (LPH 3) and documented initial consultation with the competent approval authorities regarding the approvability of the planned plant technology, including a project description and hydraulic scheme coordinated with other (specialist) planners for applying for BEW Module II funding, by September 2, 2027.
• Submission/completion of the approval-ready planning (LPH 4) for submission to the competent approval authorities, including a final report coordinated with other (specialist) planners for planning services LPH 2 to 4 in accordance with BEW Module I, by November 5, 2027.
• The client aims to obtain the building permit and any further public-law permits, considering the approval periods of the competent authorities, by June 7, 2028.
• Submission/completion of the tender documents (LPH 6) for the commissioning of the heat pumps by March 1, 2029.
• Submission/completion of the complete tender documents (LPH 6) for the commissioning of the entire plant technology by April 3, 2029.
• The planning objective for the start of continuous operation of the transformed heating network is by November 29, 2030.

The services are structured into four performance stages:

• Stage 1: Service phases 2 to 4.
• Stage 2: Service phases 5 to 7.
• Stage 3: Service phase 8.
• Stage 4: Service phase 9.

A delay in commissioning Service Level 2 beyond 11 months after the completion of Service Level 1 will result in a corresponding shift of the dates for "Vergabeunterlagen Wärmepumpen", "vollständige Vergabeunterlagen", and "Start Dauerbetrieb". The contract duration is not explicitly stated as a total, but extends through these milestones until at least the targeted continuous operation start date.

The core scope of work for this tender involves the specialized planning for the technical equipment and plant components in outdoor areas, starting from HOAI service phase 2, aimed at the fundable transformation of the district heating network.

The statement of work summary includes:

• Concept Planning: Developing a concept for integrating a new heat generator into the existing district heating system.
• Control System Design: Creating a control concept for the intelligent operation of the heat generators.
• Detailed Plant Technology Planning: Planning for plant technology, encompassing heat pumps, recoolers, auxiliary units, internal connection lines, integration into the existing energy center, operating materials, fittings, and all necessary electrical connections.
• Environmental Impact Consideration: Detailed assessment and minimization of environmental impacts, particularly noise, from the new technical installations due to their proximity to residential areas.
• Phased Implementation: The project is structured into four stages, starting with HOAI service phases 2 to 4 (Stage 1), followed by phases 5 to 7 (Stage 2), phase 8 (Stage 3), and phase 9 (Stage 4).
• Optional Services: Potential planning for a Power-to-heat plant (e.g., an electric boiler or resistance heater of approximately 2.5 MWel) including necessary auxiliary facilities for providing control power and integration into the existing system and heat storage. This also covers the technical integration of heat generators into the system and control concept.
• Funding Support: The contractor is required to collaborate in preparing necessary documentation for applying for and utilizing funding, including technical reports and summaries of planning results for BEW Module II.
• Overall Deliverable Expectation: The contractor must provide all services required for the functional, technically flawless, timely, and fundable execution of the measure, even if not explicitly detailed in the contract.
• Key Deadlines: The submission of complete bidding documents for the plant technology (LPH 6) is targeted by April 3, 2029, with the goal for permanent operation of the transformed heating network to commence by November 29, 2030.
