The new logistics centre comprises a two-storey extension, a small parts warehouse and a high-bay warehouse. Particular challenges for the planning were the confined space conditions of the property and building in groundwater caused by the high GW level.

The new extension between the existing “Longus” wing and the high-bay warehouse was realised as a two-storey skeleton structure in reinforced concrete. The vertical building loads are absorbed by point-supported and slackly reinforced flat slabs with a thickness of 38-40 cm. The existing ceiling spans of approx. 7.5 x 8.3 m ensure a very high flexibility for the use of the building floor plan. The load transfer is carried out via prefabricated reinforced concrete columns and reinforced concrete walls directly into the foundation. The stability of the building against horizontal effects such as earthquakes or wind is ensured by bracing concrete walls and stair cores. The relatively high uplift loads are absorbed by the floor slab, which is back-anchored by means of pile grids. The basement is designed as a watertight reinforced concrete structure, a so-called “white tank”.

The load-bearing structure of the small parts warehouse is characterised by a skeleton construction in reinforced concrete with a point-supported flat ceiling, while the high-bay warehouse was realised in steel skeleton construction.
