Contract notice – general guidelines, standard rules, open procedure (construction work) Replacement building for the Erich Kästner School in Marburg, plumbing work The school complex of the Erich Kästner School in Marburg-Cappel currently consists of several buildings. The formal language of the individual buildings, some of which are interconnected by connecting corridors and buildings, is typical for the construction period. The overall picture is amorphous. An overall design concept cannot be recognized. The heterogeneous overall picture means that the school lacks an “address”, a clearly defined entrance. The space available no longer meets demand. Parts of the afternoon care had to be relocated to the community center. The implementation of contemporary educational concepts is not possible in the existing floor plan structures. In addition, the existing buildings B and K have significant deficiencies such as a lack of accessibility, functional and organizational deficits, static deficiencies, inadequate fire protection and a need for energy-related renovation. Based on the above points, it was decided to demolish buildings B and K and replace them with a new building, which would also include the additional rooms for care and the cafeteria. In addition to eliminating the above deficiencies, the new building will also give the school a recognizable "address" with a well-placed main entrance. Buildings A, G, F, H and I will remain. Building A houses the administration, the teachers' room and 3 therapy rooms. The rooms in building G are used as specialist classes for music and crafts. Buildings H and I are used by the special needs school. Building A will have a small extension with technical rooms and additional storage space. The existing building G will have an emergency staircase as a second escape route with access to the room on the ground floor that is currently used as a common room. Project description extension Building B, which is currently adjacent to building A, will be demolished. Part of the basement of building B will remain standing and will serve as the floor slab for a new single-storey extension to the existing building A. Additions must be made to the demolition edges of the remaining basement. The new extension is planned to be built using timber construction, with timber frame walls (partially insulated) and a roof structure with roof beams, timber formwork and foil sealing. The outer walls will have a suspended, ventilated timber cladding. In the area where building B is to be demolished, the existing gable roof of building A must be supplemented with timber rafters and tile covering. The newly planned extension will include a technical room for the new house connection for the electrical supply to the Erich Kästner School area, as well as a technical room for the heating supply to building A. A storage room will also be created for the school's play equipment. Project description New building The new school building consists of two rectangular structures, slightly offset from one another, which are connected at the junction by a central entrance hall. Due to the topography, the southern structure is 3-storey, with a ground-level connection to the lower schoolyard, and the northern structure is 2-storey, with a connection to the upper schoolyard. The entrance hall is the central access element of the building. Access is via the entrances from the lower and upper schoolyard. The open, spacious staircase leads to the respective floors, and the elevator, which is also connected to the entrance hall, ensures barrier-free access to all floors. The clear concept of the open entrance hall offers good visual connections to all areas and thus enables good orientation in the building. The entrance hall is not just a circulation area, but a central communication zone or meeting point for students, and invites people to linger, especially with the staircase on the ground floor, which has been widened to form seating steps. The ground floor area extends only under the southern building. In this area, on the slope side, there is a central toilet core as well as storage and technical rooms. Facing the schoolyard is the large dining room with an attached kitchen and the necessary ancillary rooms. The kitchen has its own delivery from the south. The dining room has generous glazing facing the schoolyard and a large opening to the entrance hall. This opening can be closed using a mobile partition wall, or opened to the entrance hall if required, thus enabling this area to be used in a variety of ways. The dining room on the ground floor is to be made available to Cappel residents and clubs for parties or other external events outside of school hours. The classrooms are on the two upper floors. Each floor of each building contains a cluster, a so-called "learning house". The classrooms and differentiation rooms of the clusters are grouped around a central middle zone, which serves both as access and as an extended teaching area. This middle zone is structured and furnished in such a way that it can be used for teaching purposes for individual or group work, but also for supervision. Appropriate openings between the classrooms and the middle zone provide views and thus ensure that the children are well supervised. Each cluster also has a small teacher's base, so that the clusters are self-contained, "self-sufficient" learning houses with which the student community can identify and which strengthens the group feeling. On each floor, at the intersection between the two clusters, there are central toilets that can be reached in a short distance from the learning houses.
