Behördenzentrum Lüneburg Nord-LAVES, Grundsanierung und Anpassung Labor, NSA Labortechnische Anlagen Laborausbau BA 1

The contract timeline involves several key aspects:

• Contract Duration (Maintenance): The contract for maintenance has a duration of 4 years. It begins on the day following the acceptance of the construction work. This contract also includes a provision for automatic annual extensions if it is not terminated three months before its expiry.
• Construction Phases: The construction project is executed in multiple construction phases ("Bauabschnitte"). The start date for the first construction phase is determined by a contractually agreed-upon deadline. Subsequent construction phases are initiated within 12 working days after the client's request for services, in accordance with VOB/B regulations.
• Contractor's Schedule: Following the awarding of the contract, the contractor must promptly develop a construction time schedule for the first construction phase, submitting it within 14 calendar days for coordination with the client's site supervision. This schedule will then become a binding part of the overall construction plan. A similar process applies to subsequent construction phases upon the client's request.
• IAÜ Process (Commissioning, Acceptance, Handover): After the installation of the systems is complete, the IAÜ-process is structured into six phases:

1. System-wise installation check and commissioning by the installer.

2. Inspection and acceptance of the systems by a specialist, if required.

3. Creation and handover of revision documents.

4. Instruction and training of the operating personnel.

5. Trial operation.

6. VOB-acceptance.

The object documentation must be submitted six weeks prior to the scheduled date of legal acceptance.

• Interim Phase: An Interim Phase III is mentioned, which is intended to finalize the building for its intended use, including the relocation of laboratory groups.

Specific contract start and end dates are not explicitly stated, but the duration of the maintenance contract and the phased approach to construction are detailed.
