The track construction work is now firmly scheduled for the beginning of October 2021. They will be carried out by an external company. In a preliminary meeting, it was determined which preliminary work had to be done by us and how the construction site was to be handed over. On the one hand, the position of the axles of the new tracks 9 to 11 to be built, had to be precisely marked in the terrain. For this purpose, a surveying office was commissioned to make the markings on the newly constructed foundations, starting from the centre of the turntable. On the other hand, the load-bearing capacity of the raw soil in the construction area had to be checked, as it had been partially filled in, partially removed and repeatedly levelled and compacted during the construction process so far. An engineering office for geotechnics was on site for two days with two employees and carried out static load plate pressure tests as well as a review and inspection of the construction site.
