Description

The district of Darmstadt-Dieburg intends to build a new three-grade elementary school in Babenhausen on the site of a former American barracks and to convert and renovate the existing gymnasium with adjoining cinema hall. (Development plan "Kaisergärten").
The new elementary school is to be built according to the school building guidelines of the district as an inclusive all-day school. In addition to the learning and teaching area, the space program includes the subject teaching area, the administration area and the communal areas with cafeteria, library and break hall. Within the framework of a feasibility study (see attachment of feasibility study NGS, Babenhausen), the extent to which the existing property, specifically the cinema area, is suitable for accommodating individual areas of use was examined.The conclusion of the feasibility study is that a conversion of the cinema area makes sense from an educational point of view, as well as from a structural and economic point of view, and that the redevelopment variant should form the basis for further planning.Based on the school building guidelines, the parts of the room program that are suitable for use in the existing building were defined. Here, the common areas, the subject teaching area, as well as the rooms of the administrative area were identified to be accommodated in the former cinema area.This division of use allows the construction of a pure learning house in a new building, in which all general teaching areas with the associated team stations are accommodated.The renovation of the existing building, including the sports hall and cinema area, has a size of approximately 2,912 m² GFA. Due to the special structure of the outer shell, interior insulation is planned. Furthermore, the energy standard for the refurbishment should be "passive house in existing buildings" in accordance with the guidelines for sustainable building. The estimated costs for the cost group 300 + 400 amount to approx. 5.724.150,- € net.The partial new building has a GFA of approx. 3.300 m² and is to be built in the passive house standard according to the guidelines for sustainable building. The costs for the cost group 300 + 400 are estimated at approx. 6.920.000, - € net.The heat supply takes place over a district heating connection with 250 kW achievement.For the total measure conveyances are to be taken up in accordance with the hessian local guideline passive house plus solar and passive house in the existence plus solar.The objective is the completion of the new elementary school at the beginning of the school year 2026/27.Size / scopePartial new construction 3,300 m² GFA renovation/remodeling 2,912 m² GFANew outdoor facility 10,500 m²Cost framework:For budgetary reasons, the construction costs for the construction measure should not exceed the amount of € 12,650,000 net, as of 09/2022.
