From the end of March to the middle of May, the foundation and foundation work for the Vertical Sky® A 32 certification system continued on the Grevenbroich wind test field. The filling of about 44 truck mixers was necessary to pour the foundations with concrete..
Aligned and pre-filled with contact cement for the first part of the lattice tower.
Three of the foundations look like this. They are smaller and have a bevel at the foot in the upper area. After mounting the first lattice mast part, the reinforcement is completed and the head is concreted.
The crane foundation will not be beveled. It will stay that way in the foot area. Again, the reinforcement is completed only when the first part of the lattice tower is mounted. For the lattice mast and the crane two heads are provided.
The construction site is ready for a shift change. The team for the steel tower take over the construction site.
