The core scope of work for this tender involves a "Quantitative Sicherheitsbewertung" (Quantitative Safety Assessment - QSB) for the Tunnel Ortsteil Britz (TOB) on the A100 highway, including a technical retrofit.

The core deliverables and statement of work summary include:

• Risk Analysis: Conducting a complete risk analysis for the TOB tunnel system as part of the QSB, in accordance with RE-ING (Part 3 Tunnel) and BASt guidelines (2007). This involves identifying hazards and quantitatively estimating the expected frequencies and damage extents of events for various traffic scenarios (4+0, 3+0, and existing situation).
• Risk Assessment: Performing a complete risk assessment for the TOB tunnel system, also as a component of the QSB, to evaluate if the system's safety is sufficient for each driving direction under different traffic scenarios.
• Measures Planning: Developing a complete plan of measures for the TOB tunnel systems as part of the QSB, adhering to RE-ING (Part 3 Tunnel) and BASt guidelines.
• Documentation of Safety Assessments: Creating an auditable report that summarizes the results of the safety assessments in accordance with RE-ING and BASt guidelines, and comprehensively compiles the findings of existing safety investigations.
• Revision of Alarm and Hazard Defense Plans (AGAP): Updating the existing AGAP, including fire department plans, specifically for the period of construction-related tunnel tube closures (TOB), in compliance with RE-ING, EABT, recognized technical rules, and client specifications.
• Creation of an ADR Expert Opinion: Developing a comprehensive safety-technical expert opinion according to ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road) for the highway tunnel. This includes a complete scope of investigations, analyses, and evaluations to classify and assess the tunnel regarding the transport of dangerous goods, considering project-specific data, conducting a risk analysis for potential event scenarios (e.g., fire, explosion, release of dangerous substances), evaluating impacts on road users, emergency services, and the structure, determining and justifying the ADR tunnel category (A to E), analyzing possible transport restrictions/prohibitions, and coordinating with relevant norms.
• Documentation for ADR Expert Opinion: Producing a verifiable, auditable expert opinion that details the methodology, boundary conditions, and results, presents the examined scenarios and their evaluations, provides a reasoned recommendation for tunnel classification and necessary operational or structural measures, and summarizes the findings in an understandable format for authorities and decision-makers.
• Meetings: Conducting at least ten project-related meetings, including a kick-off meeting and result presentations, and providing consultation on specific safety assessment topics. This also involves supporting consultation, coordination, and alignment between the client and emergency services during the construction-related tunnel closures. Agendas, presentations, and supporting documents must be provided promptly, and all results are to be documented and distributed digitally. Bilateral working meetings with the client are part of the service and are not separately compensated.
