The slab above the ground floor of the new secondary school is currently being formed and reinforced. The challenge in this construction phase was to form the surrounding in-situ concrete balconies. The reason: they were dependent on the on-site installation of the sheet piling and the sewer work running under the balconies. Well-timed and smooth interface management was required here.
The school's new sports centre is being built in the middle building. Here, too, the slab above the ground floor is currently being formed and reinforced. A complex task that requires know-how, as the slab is being reinforced in cantilevered areas with several beams. The swimming pool is being built in the central area of the middle building. The challenge for the shell construction here is the formwork height of over 9 metres. The erection of the shoring for this height is demanding in terms of work safety and time-consuming. The floor slab for the refectory, whose construction depends on the progress of the central building, is currently being constructed.
Use of steel composite girders requires detailed delivery concept
The next major milestone is the concreting of the ceiling above the ground floor of the central building: here, 800 m3 will be concreted in one piece over an area of 1500 m2. Afterwards, the 7-metre-high columns will be concreted, on which 30-metre-long steel composite girders will lie. The steel composite girders will be used to carry the load, as the sports hall has a span of over 29 metres in the middle of the building. The girders are a special feature within the new building due to the logistics and location of the construction project. The construction site location in a residential area and the limited storage space required a detailed, two-month development of a delivery concept. In consultation with the client and all those involved in the construction, the structural engineering team found a safe and economical logistics solution. The delivery of the steel composite girders will take place in November.
