Design of the second tube for Karavanke tunnel

Owner: sfinag and DARS (Motorway Companies in the Republic of Austria and Slovenia)
Elea iC was hired to support the design of the second tube for the Karavanke tunnel project, an 8.0 km long, single tube, bidirectional motorway tunnel connecting Austria and Slovenia. It was originally designed as a twin tube tunnel, but due to lack of traffic, it was built as a single tube. After commissioning, increasingly higher traffic, support deterioration and lack of safety measures meant that a second tube was required to efficiently operate the tunnel in the future. The team is piloting BIM on this complex project where App. 190 partial models are being exchanged across disciplines and coordinated in 5 Coordination models using IFC and BCF standard for interdisciplinary collaboration.
