Germany – Architectural and related services – Sanierung und Erweiterung der naturwissenschaftlichen Fachklassen am Gymnasium Unterrieden - Architektur Vergabe von Leistungen für die Gebäudeplanung nach HOAI 2021, Teil 3 Abs. 1, § 34 Architektur, Leistungsphasen 1 - 9

Under the competitive tendering procedure in accordance with § 17 and § 74 VgV, an architectural firm is to be appointed for the expansion and renovation of the science classrooms at Gymnasium Unterrieden in Sindelfingen. Gymnasium Unterrieden was built in 1979 and consists of a three-storey main building and a three-court sports hall. In the 2025/2026 school year, a total of 769 students will attend Gymnasium Unterrieden. Classes 5 to 12 are taught in four streams. With the introduction of the nine-year Gymnasium (G9) in the 2025/2026 school year, the number of students will change, but the school will remain four-stream. The science classrooms are largely in their original condition and do not meet either current pedagogical requirements or current technical standards. The required classrooms can basically be accommodated by a restructuring of the existing spaces within the existing buildings. In addition, based on the model space programme for a four-stream Gymnasium in G9 operation, there are space requirements in the areas of full-day rooms, differentiation rooms and an additional classroom. In 2025, a preliminary investigation was carried out by the office of Zimmermann and Nagel Architekten. The results were presented to the municipal bodies in October 2025 and a fundamental decision was made to carry out a comprehensive renovation of the science classrooms and to expand the school as part of the introduction of G9. The science classrooms are to be comprehensively renovated and restructured. To cover the additional space requirements, the existing school is to be expanded by a compact two-storey new building, which is to be used as an interim building during the renovation of the science classrooms. The urban integration and the concrete design of the building structures are to be examined in variants in the further planning process. The construction measure is to be implemented during ongoing school operations. For this purpose, a construction and moving concept with suitable construction sections and relocations is to be developed in order to keep the disruptions to school operations as low as possible. Room enlargements within the existing structure are possible by relocating corridor walls; however, an extension of the existing areas by relocating the external facades is not planned. The science classrooms to be renovated in the existing building comprise a usable area of approximately 1,400 m². To cover the additional space requirements, the extension new building with a required usable area of approximately 540 m² is planned. The approximate costs for the comprehensive renovation of the science classrooms including the extension new building, determined in the course of the preliminary investigation, amount to a total of approximately 12.3 million € gross for cost groups 200 to 700. Planning will begin immediately after the contract is awarded. The selection committee is scheduled for week 42/2026, and the tender negotiations are scheduled to take place in week 48/2026. Bidding as a consortium is possible (the form 234 is to be completed accordingly). In the case of consortia, the information and references apply in total for the consortium. The reference is also considered to be fulfilled if the service was provided as the responsible project manager in another office. In this case, a written confirmation from the other office or the client must be submitted regarding the responsible project management (Form I.3 EU is to be completed).
