The KBK requires geotechnical investigations in order to be able to consider the results of these investigations as a basis for the tendering of these construction measures. The scope of these construction measures each consists of sections 2 to 10, with each section length of up to 60 m and channel depths of 2.00 to 5.00 m. In the performance description, approximately 10 construction measures were estimated, depending on the only roughly predictable new construction need in the canal network. Furthermore, approximately 3 construction-accompanying geotechnical investigations were taken into account in the performance description.
