The Mitte district plans a complete renovation of Building 2 (after-school care building) at the location of Gesundbrunnen Primary School at Prinzenallee 9, 13357 Berlin. The sanitary facilities are to be rebuilt and supplemented, building services technology is to be repaired, barrier-free access to the building (including installation of an elevator) is to be established, fire protection, AMOK (active shooter) and acoustic concepts are to be created and implemented, and an energy-efficient window renovation including sun protection is to be carried out. Furthermore, minor interior alterations and pollutant remediation are necessary. During construction, the cafeteria, toilets, and GE classes (classes with a focus on "Intellectual Development") will be relocated to containers in the schoolyard. Additionally, the roof should, if possible, be equipped with photovoltaic elements.
Structural engineering services according to performance phases 1 to 6 in accordance with § 51 HOAI are to be provided.

It is also planned to restore the currently single-story building section on the east gable back to the three-story condition of 1951. The elevator system, sanitary facilities, and possibly the GE classes are to be housed in the additional rooms. Financing for the restoration is still under clarification. Therefore, the restoration is requested as an optional service package.
The current estimated budget according to rough cost estimation (cost groups 300/400), without restoration of the east gable, is 7,306,657 euros gross.
The after-school care building of Gesundbrunnen Primary School was built between 1893 and 1894 as the 9th secondary school by Hermann Blankenstein and Paul Hesse. The brick construction building is one of the typical school buildings of City Building Officer Hermann Blankenstein. It is protected as a historic monument together with the entire ensemble including the main building, gymnasium, and residential building.
The building is used for school purposes – classrooms, after-school care, and cafeteria. In the future, integration classes with GE children are also to be accommodated in the building.
The following measures are planned:
- Energy-efficient enhancement of the building including restoration of windows and facade in coordination with the monument protection office
- Renovation of the basement with moisture damage and necessary sealing
- Barrier-free access to the building by installing/adding an elevator system (positioning still to be coordinated with the monument protection office)
- Provision of barrier-free sanitary rooms suitable for GE classes (classes with focus on "Intellectual Development") including changing area
- Increase in the number of sanitary rooms (separate toilet, washrooms, and anterooms for boys and girls each on the ground floor, only girls on the 1st floor, only boys on the 2nd floor)
- Preparation of a quiet room or a separable area for children with sensory overload
- Inspection and possible renovation of the roof surfaces
- Checking the static conditions of the roof for PV system and possible installation of PV system
- Structural examination of ceiling beam layers and possible reinforcement
Additional / Special services:
- Structural preliminary investigation regarding the feasibility of a photovoltaic system on the roof surface
- Structural pre-dimensioning and static evaluation of the additional loads of the planned photovoltaic system
- Optional: Consulting participation as well as structural preliminary investigations, pre-dimensioning and static assessment regarding the extension of a building section based on variants developed by the object planner, including assessment of load-bearing capacity, load transfer, and any necessary structural modifications
- Updating of the building log according to VDI 6200 (status February 2010) in accordance with Annex B
For the required specialist planning according to Part 4 HOAI, specialist engineers are involved in the planning by the client, whose contributions are to be used and whose services must be coordinated in terms of time and subject matter. The services must be coordinated and incorporated with structural engineering. It is planned to hand over the following services to other technical participants: fire protection concept, object planning specialist planning, technical equipment/elevator planning specialist planning, landscaping planning, soil investigation (supplement).
The following have already been commissioned separately: preliminary static investigation for elevator installation and static examination of the extension with regard to a possible extension.
The following dates must be observed:
LPh 1 (VPU): 1st quarter 2027
LPh 2 and 3: 3rd quarter 2027
LPh 4: 4th quarter 2027
LPh 5: 3rd quarter 2028
LPh 6 and 7: 4th quarter 2028
Start of construction: 1st quarter 2029
Completion of construction: 1st quarter 2031
