The drilling of the deep wells was completed in time before the official holidays. At the same time, the crane foundation was constructed and was already adequately compacted. At this time, the last gathering pipes for the geothermal energy are still being hooked up and lead to the house entrance, so that the remaining layer of the excavation can be removed as soon as possible. Thereafter, the clean layer will be placed underneath the floor slab. This will then complete the preparatory work in the excavation pit and the real structural work can start, with the building rising to the top.
