The core scope of work and statement of work summary for this tender encompass a wide range of engineering and planning services, structured across various project phases.

The key areas of work include:

1. Surveying Technical Foundations and Digital Terrain Modeling: This involves conducting topographical and morphological terrain surveys, with differentiated requirements for core and outer areas, capturing essential control points and planning-relevant objects. It also includes the processing and evaluation of collected data, the creation of digital site models, and the integration of existing inventory and terrain data. A significant part of this phase is the incorporation of information regarding channels, lines, cables, underground structures, and land registry data from existing documents, as well as existing public law designations. Deliverables include measurement data, calculation protocols, an explanatory report with accuracy proof, lists and overviews of fixed points, basic plans, and overview plans, all to be provided in both analog and digital formats, specifically OKSTRA-data format for basic data. Furthermore, it involves the selection of elevation points and break lines for ground surface description, the calculation of a digital terrain model (DGM) and corresponding contour lines, and the derivation of terrain sections (cross-profiles and longitudinal profiles). Heights are to be represented in point, raster, or contour line form.

2. Object Planning for Traffic Facilities and Special Road Construction Services: This includes tasks such as identifying unique impacts not covered by standard norms and inspecting comparable projects. It also covers the creation of utility inventory plans, conducting sustainability studies, cost-benefit analyses, and economic feasibility assessments, alongside the procurement of official documents like land register and cadastral excerpts. Further responsibilities involve updating cost-benefit analyses, performing detailed signal technical calculations, assisting in administrative agreements, providing evidence of compelling public interest (e.g., for area and species protection), conducting fictive cost calculations for cost sharing, and detailed calculations for traffic control systems. The scope also includes compiling necessary documentation for the "Draft Planning" and "Execution Planning" audit phases. Additionally, it requires object-spanning, integrated construction schedule planning, overall project coordination, developing comprehensive flow and network plans, and planning the lighting for specific crossing points (GRW), including determining lamp locations and dimensioning their illumination.

3. Construction Supervision, Documentation, and Deconstruction Planning for Engineering Structures: This area involves the review and processing of contract addenda, which includes evaluating necessary changes, drafting addenda (in GAEB format), scrutinizing addenda offers, securing necessary proofs and clarifications, preparing and documenting negotiation processes, drafting addenda order letters, and documenting the entire addendum procedure. A core deliverable is the creation of a comprehensive structure logbook, which must include all relevant data and documents (e.g., plans in DIN A4 format), and the preparation of as-built plans. These as-built plans must incorporate content directories for structural analyses, drawing directories, steel lists, prestressing and grouting protocols, material quality certificates, general building permits, survey results, as-built overview drawings, parts lists, and corrosion protection plans, with a focus on verifying execution plans against actual construction. The tender also requires local construction supervision for engineering structures. For deconstruction (demolition) projects, the work entails exploring local conditions, analyzing existing documents (like structure logbooks and execution plans), providing structural-constructive advice considering stability, serviceability, and economic efficiency, and assisting in the development of planning concepts and variants. This includes cost estimation and summarizing the preliminary planning results in written and graphical form, explaining variants and the decision-making process. The draft planning phase requires developing the design through detailed drawings, considering all specialist requirements, and integrating and coordinating specialist planning efforts. This involves defining precise deconstruction steps for each structural component (e.g., superstructure, piers, abutments, foundations), graphically representing deconstruction phases (in floor plans, longitudinal, and cross-sections, including auxiliary structures and special equipment), and developing a comprehensive deconstruction and disposal concept. This concept must detail waste types, disposal options, and consider the results of chemical-physical preliminary investigations related to environmental contaminants, adhering to the Circular Economy Law (KrWG).
