Germany – Architectural and related services – Erweiterung und Sanierung Carl-Orff-Grund- und Mittelschule Dießen am Ammersee - Objektplanung Gebäude und Innenräume, Leistungsphasen 2 (teilweise) und 3-9 gemäß §§ 33 ff. HOAI

The municipality of Dießen am Ammersee plans to expand and renovate the Carl-Orff primary and secondary school in Dießen am Ammersee. The reason for the planned measure is the current lack of space for full-day care in the primary school sector. The additional space requirement is to be covered by an extension new build (Building F). At the same time, the heating centre is to be renewed. As part of a preliminary concept, variants for the extension were examined, which led to a preferred variant. For functional and economic reasons, an extension new build between the existing buildings E and B is therefore being sought. With this extension and the conversion of the attic of Building A with 1,380 m² of usable area, a very economical extension solution is available. In addition to the additional space requirement, the building stock (especially Building E) also shows a considerable need for renovation and modernisation. This is particularly the case in the area of technical systems, with regard to fire protection, room acoustics and lighting. As the total investment volume/cost framework for the extension, conversion and renovation measures, approximately 19.3 million € gross (cost groups 200-700, DIN 276) was determined as part of the preliminary concept. The milestones for implementing the project currently provide for: - Planning/performance start: mid-October 2026, - Construction start 1st phase = extension new build Building F, conversion attic Building A: spring 2028, - Completion 1st phase = extension new build Building F and conversion attic Building A: start of school year 2029/30 (= mid-September 2029), - Construction start 2nd phase = renovation and expansion of Building E: summer holidays 2029 (= August 2029), - Completion 2nd phase = renovation and expansion of Building E: end of 2030. It has not yet been finally decided whether the renewal of the heating centre will be structurally advanced or implemented as part of the 1st construction phase and is dependent on the planning concept still to be developed in this regard. It is intended to award the following services (in stages) with this tender: building and interior design, performance phases 2 (partially) and 3 to 9 according to §§ 33 ff. HOAI.
