For "structure 3-1 (bridge over the Rohrbach)," tender documents are due on March 1, 2028, and October 2030 for other segments. For "Baulose BW 0-1; BW 2-1 and BW 3-3," preliminary investigation and structure sketch are due on November 26, 2027, and the structure design with crossing agreement and preliminary design BW 2-1 on May 26, 2028.

The core scope of work and statement of work summary for this tender involves a comprehensive range of engineering services for construction projects, with a strong emphasis on Building Information Modeling (BIM) methodologies.

Key areas of work and deliverables include:

• Project Planning and Design: This encompasses draft design planning, which involves demonstrating the implementation of project goals and requirements, outlining planned areas, providing planning and cost key figures, and integrating results into client-specified databases. It also includes creating and summarizing explanatory reports. The tender requires specialized calculations, determination and justification of eligible costs, participation in financial planning, and the preparation of funding applications. Further, it involves explaining preliminary designs to third parties, pre-coordinating approval with authorities, and preparing detailed cost calculations according to DIN 276:2018-12.
• Structural Engineering: This involves preparing verifiable static calculations for structures, considering building physics requirements, and recording normal construction states for engineering structures. Deliverables also include creating position plans for the structure, detailing static positions, structural dimensions, traffic loads, material quality, and construction specifics in design drawings. The scope also includes compiling structural planning documents for approval, coordinating with inspection authorities and engineers, and completing and correcting calculations and plans based on regulatory feedback.
• Construction Supervision and Management: This involves local construction supervision, which includes overseeing the execution of construction services, assessing and validating additional claims, conducting quality control tests, managing defect rectification, and thoroughly documenting the construction process. It also requires participation in measurement verification with contractors, official inspections, and rigorous invoice reviews. Cost control and setting up a detailed, networked construction schedule are also key responsibilities.
• Documentation and Reporting: Core deliverables include creating a comprehensive building logbook with all relevant plans and data. The tender also mandates the creation of as-built plans in accordance with ZTV-ING, including structural analysis content, drawing directories, material lists, and various certificates and survey results. Finally, summarizing, explaining, and documenting all results for the Final Project Document (FPU) is required.
• BIM (Building Information Modeling) Integration: A significant part of the tender focuses on BIM. This includes overall BIM coordination of all specialist models within the project. Specific BIM deliverables are the creation and updating of a BIM Execution Plan (BAP), clarifying data exchange requirements with authorities, and developing a BIM Quality Assurance Concept with associated test protocols. The scope also involves the preparation of provided documents, creating a 3D model of the preferred variant, and performing model-based quantity and cost calculations. The project requires deriving 2D plans for specialist planners in conventional formats, integrating and preparing landscape planning data for the 3D model, and deriving 2D plans for approval documents. BIM also plays a role in the coordination of specialist trades (AwF 050), involving cross-service coordination and quality assurance of specialist models, including the use of a task management system for model-based collaboration and communication, and the provision of BIM inspection reports.
• Regulatory and Legal Compliance: The tender includes submitting applications for water rights after consultation with relevant parties.
