Description
The Brenner Base Tunnel (BBT) is a 64km long railway tunnel connecting Austria and Italy. Once completed, it will be the world's longest rail link underground. In addition to the two main tubes, the project comprises a complex set up of exploration adits, crosscuts, emergency stops and additional access tunnels, excavated by TBM and SCL methods. Dr. Sauer & Partners provided tender support services for the 18km lot H51 Pfons-Brenner and was responsible for creating the bid documents as well as conducting QA/QC services. The documents covered issues such as TBM choice, annular gap filling, reuse of excavated rock, rail delivery of construction materials, construction logistics and pre-excavation grouting.
