The inner-city extension of the existing school in Längenfeldgasse was built as part of the Vienna School Extension Program PFERD – PFlichtschulERweiterungsprogramm-Dringend – and houses a 17-class elementary school and two vocational school units with 15 and six classes respectively.
The new building is a monolithic, seven-storey structure in reinforced concrete skeleton construction with external dimensions of 64 m x 49 m and 25 m in height.
The primary axis grid – alternating 7.85 m and 3.00 m – both longitudinally and transversely – was determined by the spatial configuration of the four cluster areas, each with four educational rooms.
Since the load-bearing layer is four to five meters below the ground level of the present site, a soil replacement was necessary in some areas with a layer thickness of up to one meter. In contrast to the designed raft foundation, a deep foundation with in-situ concrete piles (D = 60 cm) was therefore necessary in large parts.
