Germany – Engineering services – MPI für Biogeochemie, Jena - Erweiterung Institutsgebäude: Laborplanung

The institute building, completed at the beginning of 2003, is divided into three parts, A, B and C, connected by a multi-storey entrance hall and further underground structures (partly lit by an inner courtyard). The space requirement plan for the extension building essentially comprises standard areas for laboratory and office use as well as special areas for the greenhouse with a technical facility. Due to the changed scientific working methods, the installation of greenhouse cabins and technical facility cabins within a contiguous large greenhouse is necessary. This makes it possible to achieve energetically optimised climate stability in the individual cabins ('house-in-house principle'). Due to the site situation with a slope, only the area of the existing greenhouse remains as the location for the extension building. This must be demolished due to the new scientific requirements and replaced by a new greenhouse/technical facility building in connection with the extension building. As a result, renovation work will also be carried out on and in the existing building, in the technical infrastructure and in the supply and disposal lines in the ground. Provisional measures secure the institute's operations during the construction phase. Currently, no interim accommodation is necessary or planned. The scope of services mainly concerns the following construction measures at the MPI for Biochemistry in Jena: - Demolition of the old greenhouse, - Extension building of an institute building with office, special and laboratory areas - New construction of a greenhouse - resulting renovation work in/on the existing building and in the technical infrastructure and in the supply and disposal lines in the ground. The estimated construction costs of the measure EBIO 001 amount to 7,5 million € (net) KG 300+400, the total construction costs (KG 200-700, without KG 611 and KG 612) to 12,5 million € (net). The extension building for the office and laboratory areas will extend to levels OG 1, EG, U-1 and possibly U-2. Similar to the existing building, the extension building is to be designed as a two-shell structure with a widened central zone for access. Due to the static support measures to the existing structure (back-anchored bored pile wall), a half-storey may possibly arise on level U-2. Further technical rooms and a further delivery zone (due to the slope) could be accommodated here. The connection to the existing structure is made via a connecting bridge on level OG 1. The mandatory requirement for this arises from the specification of the science that the extension building together with the existing buildings forms a research institute as a functional unit with short distances and weather-independent connection between the various research units. Furthermore, the connection to the existing buildings can be implemented on level U-1. The space requirement plan for the extension building essentially comprises standard areas for laboratory and office use. The areas amount to approx. 590 m² NUF 1-6. The additionally required parking spaces (12 units) will be located in the outdoor facilities, a underground car park is not possible. Further details can be found in Annex 01. Special note regarding tender questions due to special external events (e.g. Sars-COV-2 or Ukraine war): Please take into account possible or recognisable impairments in your offer, e.g. with regard to the availability of materials and products, manpower, a possibly delayed submission of required evidence, effects on possible subcontractors, etc. Please submit questions arising in this context in good time before the tender deadline via the eTendering messaging system.
