Strong team performance ensures project success
In order to keep the school running, the new secondary school in the east and a central building with a gymnasium and swimming pool in the north of the site were constructed after the partial demolition of the existing school buildings. The new primary school is planned for a later construction phase in the west.
The facilities shared by both schools are stacked in the central building to save space: a swimming pool and the canteen are located in the basement, a double gym on the first floor and an all-weather sports field on the roof.
‘At the moment, finishing and extension work is still ongoing,’ explains project manager C. Summersammer, emphasising: ‘Due to the tight time frame and the extremely limited space available on the construction site, the strong team performance as well as the good cooperation with external trades and the client cannot be emphasised enough.’ The client for the project is the City of Munich, Department of Education and Sport, Building Department (project management).
High-load-bearing components enable large spans
The complex stacking of different usage units placed high demands on the structural design of the central building. The use of high-load-bearing components made it possible to construct the sports hall on the first floor and the roof area above it as an all-weather sports field. To effectively compensate for vibrations that inevitably occur during use and to ensure the stability of the structure, vibration dampers were integrated into the composite beams.
The sports hall as well as the swimming pool are designed without supports. Eleven steel beams ensure load transfer and enable the extraordinary spans that give the sports wing its openness and spaciousness. Each beam measures an impressive 30 metres in length, has a height of 1.50 metres and weighs 40 tonnes. Due to its heavy weight, the steel girder had to be delivered by heavy transport without hollow core concrete – a planning and logistical masterpiece given the dense residential areas. The hollow core concrete was added later on site. This required the installation of extensive work platforms with a height of 9 metres. The steel girders had to be reinforced with hollow core concrete for fire protection reasons.
