The core scope of work for this tender is the technical construction controlling (technisches Baucontrolling) for the "Sanierung der Stadthalle Braunschweig" (Renovation of the Braunschweig City Hall), starting from October 2026.

The Statement of Work summary and core deliverables include:

• Technical and Qualitative Review: The contractor is tasked with technically and qualitatively checking, documenting, objecting (if necessary), and advising the client on the implemented and upcoming execution qualities of construction work for cost groups 300 and 400 according to DIN 276.
• Consultant Role: The contractor explicitly does not undertake construction management tasks but acts solely as an expert consultant to the client.
• Project Focus: The project emphasizes the interaction of contemporary use with the preservation of the historically listed substance, aiming for long-term, sustainable operation with modern technical building equipment while maintaining the monument's identity.
• Regular Site Inspections and Documentation: This involves regular, likely weekly, on-site inspections to verify and document the performance of the executing trades and construction progress against essential technical and qualitative requirements, planning, and user specifications. Deliverables include structured written protocols within five working days of each inspection, detailing the date, participants, construction and execution status per trade, identified quality deviations and defects with photographic documentation, assessment of execution quality, action recommendations, open items with responsibilities and deadlines, and status tracking of previous protocol points.
• Accompaniment of Trade Acceptances: Preparing for acceptances, participating in formal acceptance meetings, creating acceptance protocols according to VOB/B, and providing a qualified acceptance recommendation (acceptance / acceptance with reservation / refusal) to the client.
• Defect Evaluation: Establishing and evaluating existing defects to determine acceptance capability and, if necessary, assessing justified retentions/additional expenses, reduced costs, or substitute performance. This includes classifying defects by severity and evaluating their impact on acceptance capability.
• Consultation on Damages and Technical Differences: Providing advice, comments, and support for damages or technical discrepancies between parties, including qualified written or oral statements on technical disputes upon client request.
• Handover Accompaniment: Supporting the client during the sectional handover of completed areas to the user and documenting the handover status, with a particular focus on the building technology interface.
• Special Requirements (Monument Protection and Pollutants): Considering the specific context of a listed building, observing and documenting the proper treatment and preservation of listed building components, the correct handling and disposal of residues from pollutant remediation during construction, and the qualitative implementation of planning adjustments arising from findings on the existing structure.
• Document Management: All results, documents, and plans must be entered into the WINPLAN document management system, and the contractor is obligated to input protocols, reports, and other service results according to client specifications and the project handbook.
• Optional Services (billed by time and effort):
• Participation in bi-weekly project Jour-Fixe meetings with the client, planners, and construction management.
• Commissioning Support: Analyzing and evaluating commissioning planning and assisting in its execution. This includes checking TGA (Technical Building Equipment) commissioning plans for completeness and technical plausibility, accompanying on-site commissioning, and documenting deviations and open items.
