The project
The gradual building over of the area with halls should enable the management of the log yard at any time. The chosen concept provides for a hall across the axis of the railroad and the road, which can be extended in both directions. With a floor plan of 14 x 55 m, only the first of four halls will be built. The details The supporting structure was built on a grid of 5.00, or 5.50 m in order to still obtain economical cross-sections for the solid wood rafter purlins.

The construction method
Since the hall was relatively narrow at 14 x 55 m and no frames could be used for the supporting structure due to lack of space, we opted for a combined supporting structure solution: Curved gable roof girders on pendulum columns formed the primary supporting structure; a spatial steel core with flexurally rigid frame corners was installed at the passageway. Horizontal wind forces are transferred to the steel crosses in the end walls and to the steel core by horizontal truss bracing. The details were specifically designed for rapid erection: Supporting structure as pure skeleton construction, steel brackets inside, walls prefabricated as elements and inserted from the outside. This means that, in theory, any wall element can be removed without affecting the supporting structure. This also ensures flexibility for conversion and expansion.
