The core scope of work for this tender, identified as "Bauüberwachung" (Construction Supervision), involves several key areas:

1. Performance and Quantity Determination (Leistungs- und Mengenfeststellung): This includes receiving and processing performance data (DA 11 files) from the construction contractor (ANBAU), verifying quantity determination lists, ensuring quality execution, addressing quantity overruns, and requesting corrections to faulty data. It also entails conducting reconciliation meetings for undisputed services and providing monthly status reports with performance evaluations and forecasts.

2. Amendment/Change Order Processing (Nachtragsbearbeitung): The scope covers active management and prevention of change orders, including immediate notification of deviations, timely evaluation of obstruction and additional cost notices, assessing demand and alternative positions, participating in negotiations, and providing detailed factual assessments for change order claims. It also involves participation in the NEuPP (Nachtragseinreich- und Prüfplan) process and assisting in legal disputes.

3. Defect Management (Mängelmanagement): Tasks include recording and preparing defect notifications, tracking and monitoring their rectification, and listing all limitation periods for defect claims related to construction components.

4. Billing (Abrechnung): This involves reviewing billing drawings, quantity determinations, and hourly wage slips. It also requires informing the client of significant quantity changes (over 10%), reviewing all types of invoices (advance, partial, final), and, for electronic billing, continuous reconciliation with the ANBAU regarding rendered services.

5. Documentation (Dokumentation): Core deliverables include creating and maintaining a verifiable construction file (potentially digital), generating digital photographic documentation of key construction phases with detailed descriptions, and ensuring this documentation is available on-site and handed over to the client upon completion. Specific documentation for TSI conformity for relevant measures according to EIGV of DB InfraGO AG is also required.

6. Services under Construction Site Ordinance (Leistungen nach der Baustellenverordnung): This entails performing tasks during the construction execution phase as per § 3, paragraph 3 BaustellV in conjunction with section 3.2 of RAB 30, including updating preliminary announcements for relevant changes.
