S13 Track Construction Works Bonn-Oberkassel – Contract Modification

Summary

This is a contract modification notice for track construction works (S13 Lot 6.001) involving 3/4-track railway expansion in Bonn-Oberkassel, Bonn, Germany. The modification addresses additional soil excavation disposal requirements that arose during construction, requiring reclassification under new waste disposal regulations (Ersatzbaustoffverordnung) effective August 2023. The original contractor (THG Baugesellschaft mbH) will continue performing these disposal services as they cannot be separated from the main works.
