Tunnel Log / Highway Tunnel
Tunnel Log on Draženci – Gruškovje highway is a tunnel in Slovenia located on the highway from Vienna to the Adriatic Sea. BEXEL developed the 3D BIM model in collaboration with IRGO Consulting as the main designer and BEXEL as the BIM engineering expert, and participated in the planning phase of the new tunnel. We were a provider of BIM services, which was the first time BIM was applied on any infrastructure project in Slovenia.
BEXEL developed a detailed 3D BIM model of the tunnel containing elements of all trades, including earth excavation, primary tunnel construction, anchoring, the entire secondary construction, utilities, signaling and all road layers. The 3D BIM model was used for generating detailed 4D construction simulations according to the proposed Execution programme, and modified in order to achieve optimal sequencing of activities. Detailed Quantity takeoffs of all workitems were extracted directly from the 3D BIM model in order to support the budgeting process in the early stages of the project as well as the tendering process later on.
