Before the foundation could be concreted, the steel supports for the new partition wall had to be erected. Together with the crossbars to be installed later, these form the steel framework, which will then be bricked up. First, the position of the posts had to be measured. Then core drillings were made in the old foundation, the post anchors aligned and grouted with swelling mortar.
After it had hardened, the steel posts were erected with the help of the two-way excavator and fixed to the anchors at the bottom. At the top, they were fixed to the existing roof truss.
