The core scope of work and statement of work summary for this tender encompass several key areas related to infrastructure projects, primarily focusing on the B85 GRW in Rothenkirchen and bridge renewals.

Object Planning for Traffic Facilities (Objektplanung Verkehrsanlagen): This involves determining special impacts, inspecting similar objects, creating utility inventory plans, conducting sustainability and cost-benefit analyses, and performing economic viability assessments. It also includes detailed signal-technical calculations, participating in administrative agreements, proving the necessity of the measure based on public interest (e.g., nature protection), performing fictitious cost calculations for cost sharing, and detailed calculations for traffic influence systems. Deliverables include compiling documents for the "Draft Planning" and "Execution Planning" audit phases, integrated construction schedule planning, overall project coordination, preparing schedule and network plans, and specific planning for GRW lighting, including lamp locations and illumination dimensioning. Furthermore, it entails participating in obtaining consent from affected parties and reviewing and evaluating alternative offers.

Specialized Planning for Structural Engineering (Fachplanung Tragwerksplanung): This includes on-site inspections to verify existing documents and assess structural conditions, preparing comparative calculations for various solution options, developing load plans, and conducting preliminary verifiable calculations for essential load-bearing parts and foundations. Core deliverables are feasibility studies for structural rehabilitation, which outline suitable reinforcement measures, provide static proofs, schematic representations of measures, and cost estimations. It also involves economic viability studies comparing rehabilitation with new construction options.

Demolition Planning for Engineering Structures (Rückbauplanung Ingenieurbauwerk und Tragwerksplanung): This involves preliminary planning, including cost estimation for different variants and documenting the results with explanations of variants and reasons for selecting the preferred option. The design planning phase focuses on developing the demolition concept with graphical representations of individual demolition steps for components like superstructures, piers, abutments, and foundations, detailing temporary constructions and special equipment. A critical deliverable is the demolition and disposal concept, which identifies waste types, outlines disposal options (recycling or elimination), and considers environmentally relevant substances from preliminary investigations. For the preparation of awarding, tasks include determining quantities of rebar, steel, and timber for demolition and temporary constructions, and assisting in creating performance specifications and bills of quantities.

Engineering Surveying (Ingenieurvermessung): This service establishes surveying technical bases through topographical/morphological terrain surveys, recording control points and planning-relevant objects with specific accuracy requirements for core and outer areas, and utilizing various surveying methods (e.g., tachymetric, satellite-aided, photogrammetric, laser scan). It also involves processing and evaluating collected data, creating a digital elevation model with planning-relevant elevation points, and incorporating existing data for channels, lines, cables, underground structures, land registry information, and public law designations. Key deliverables are detailed plans illustrating the situation in the planning area, including base maps and overview maps.

On-site Construction Supervision (Örtliche Bauüberwachung) and Related Services: For engineering structures, this includes reviewing change orders, drafting change order documents, evaluating proposals, and documenting the process. Other deliverables are the creation of a comprehensive building logbook containing all relevant data and plans, and the preparation of as-built plans. These as-built plans encompass content directories for stability proofs, drawing directories, material lists (steel, prestressing steel, timber), quality proofs of materials, official approvals, survey results, as-built overview drawings, parts lists, and corrosion protection plans. It also involves verifying that execution plans conform to the actual construction and updating them as necessary.
