New building in harmony with the surrounding nature

The building will be constructed on a plot of around 2,100 m² and will consist of a tall structure with a wooden roof and a low structure faced with clinker bricks for the functional sports rooms. The property is surrounded by forest and borders the sports field on one side. The use of natural materials and renewable resources such as wood, as well as a green retention roof with photovoltaic elements, allows the design by Renner Architekten to blend in with its surroundings.

Slim bored piles are both cost-effective and environmentally friendly

The ground consists of a two-metre layer of fill, a further two metres of peat and sand until solid ground is reached. Therefore, a pile foundation was required for load transfer. 43 steel pipe piles, each ten metres long and 40 centimetres in diameter, were driven into the ground using internal pipe ramming, which is a quiet process.

The steel pipe pile is a full displacement pile and is one of the ‘green pile methods’ used by PORR Spezialtiefbau. It offers a number of advantages. The steel is fully recyclable, the slim shaft diameter saves a considerable amount of concrete and no drilling debris is produced due to complete soil displacement. This efficient use of materials and the elimination of disposal trips conserve resources and reduce the CO₂ footprint of the construction site.
