Regional-Stadtbahn Neckar-Alb Projektgesellschaft mbH - Europaweite Vergabe von Planungsleistungen für die Entwurfs- und Genehmigungsplanung der Regional-Stadtbahn Neckar-Alb

The contract timeline is not explicitly stated in the documents. While there is a mention of "Vertragslaufzeit" (contract term/duration), no specific start date, end date, or total duration for the contract itself is provided. The documents do outline a timeline for the *tender process*, which includes:

• Phase 1 - Teilnahmewettbewerb (Participation Competition): The deadline for submitting the participation application is September 8, 2026, 12:00 PM.
• Phase 2 - Angebots- und Verhandlungsphase (Offer and Negotiation Phase): This phase follows Phase 1, where selected companies are invited to submit offers and engage in negotiations.

The core scope of work for this tender involves planning services for the design and approval planning (service phases 3 and 4) of the first section of the BOStrab infrastructure, specifically the connection to the DB InfraGO railway network in Reutlingen. This section is approximately 7 km long and includes system change points for the Neckar-Alb-Bahn. The project aims to continue planning based on existing preliminary designs (including a preferred route from 2026) to achieve approval readiness and prepare all necessary documents for a plan approval procedure.

The planning encompasses the interdisciplinary processing of all required trades for design and approval, as well as the coordination of accompanying expert opinions. Key aspects include managing interfaces between BOStrab and EBO infrastructure, planning several engineering structures (overpasses and underpasses), designing system change points between 750 V DC and 15 kV AC, and coordinating with DB InfraGO.

The project is divided into several sub-areas:

• Sub-area 1.1.1: Branch towards Metzingen.
• Sub-area 1.2.1: Connecting track to DB Reutlingen West.
• Sub-area 1.2.2: Tram line depot (excl.) track triangle Tübinger Straße - Reutlingen West.
• Sub-area 1.2.3: Tram line track triangle Tübinger Straße - track triangle Listplatz.
• Sub-area 1.3.1: Tram line Reutlingen West junction Galgenberg (branch towards Tübingen).
• Sub-area 1.3.2: Tram line junction Galgenberg - Markwiesenstraße.

The required planning services, in accordance with HOAI service phases 3 and 4, include:

• Object planning, inclusive of service phases 1 and 2 (e.g., buildings for substations, toilets, switch houses).
• Traffic system planning.
• Engineering structures planning.
• Structural engineering planning.
• Technical equipment planning (LST, 16.7-Hz systems including overhead line equipment (OLA), 750-V-DC systems including OLA, 50-Hz systems, and light signal systems (LSA)).
• Other services, such as interdisciplinary coordination, approval services, and surveying services.

All planning services must be executed using the BIM method (BIM-5D), with the ultimate goal of producing a fully coordinated, approval-ready design and approval planning, complete with all necessary documents, verifications, reports, plans, and models for the plan approval process.
