Germany – Load-bearing structure design services – Sanierung und Erweiterung der naturwissenschaftlichen Fachklassen am Gymnasium Unterrieden - TWP Vergabe von Leistungen für die Tragwerksplanung nach HOAI 2021 Teil 4 Abschnitt 1 § 51, Leistungsphasen 1 - 6 mit Besonderen Leistungen

Under the award procedure with competitive dialogue in accordance with § 17 and § 74 VgV, a structural engineer is to be selected for the expansion and renovation of the specialist classrooms at Gymnasium Unterrieden in Sindelfingen. The focus of the structural engineering services is on the new building. 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 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 specialist classrooms are largely in their original condition and do not meet either today's pedagogical requirements or current technical standards. The required specialist classrooms can basically be accommodated by a restructuring of the existing areas within the existing buildings. In addition, based on the model room 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 Zimmermann und Nagel Architekten. The results were presented to the municipal committees in October 2025 and a fundamental decision was made to carry out a general renovation of the science specialist rooms and to expand the school as part of the introduction of G9. The specialist 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 specialist classrooms at the same time. The urban integration and the concrete design of the building will be investigated 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 disruption to school operations as low as possible. Enlargements of space within the existing building are possible by moving corridor walls; an extension of the existing areas by moving the outer facades is not planned. The specialist classrooms to be renovated in the existing building comprise a usable area of around 1,400 m². To cover the additional space requirements, the extension new building with a required usable area of around 540 m² is planned. The estimated costs for the general renovation of the specialist classrooms including the extension new building, as determined in the preliminary investigation for cost groups 200 to 700, amount to a total of around 12.3 million € gross. Planning will start immediately after the award of the contract. The selection committee is scheduled for week 43/2026, and the tender negotiations are scheduled to take place in week 49/2026, according to the current status. Bidding as a consortium is possible (Form 234 must be completed accordingly). In the case of consortiums, the information and references apply in total for the consortium. The reference is also considered 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 regarding the responsible project management must be submitted (Form I.3 EU must be completed).
