LOCATION: NORWAY

CLIENT: Confidential

AREA: 4,4 Km

BUDGET: 650 M €

This project is part of a strategic initiative to modernize railway infrastructure in southern Norway, within the national InterCity connectivity program. The double-track railway route includes two main tunnels (2.3 km and 2.7 km), a 500 m cut-and-cover tunnel, and a new station in a key city of the region. The goal is to increase transport capacity and reduce travel times on one of the country’s busiest lines.

The construction crosses dense urban areas and geologically complex terrain, requiring advanced engineering solutions. The main tunnel, excavated using drill and blast methods, has a cross-section of 130 m², with a width of 13.5 m and a height of 10 m. Breakthrough was achieved in March 2021, marking a technical milestone in the project.

The design includes tunnels, viaducts, stations, railway systems, and drainage, all developed under BIM Level 2 methodology, enabling precise coordination between disciplines and efficient information management.

ACTIVITIES

ACTIVITIES

  • We modeled in 3D and performed reinforcement measurements in Revit for technical buildings, ensuring structural detail accuracy and compliance with project specifications.
  • We modified geometry, created 2D reinforcement drawings, and performed measurements for technical buildings and interior walls, optimizing design and measurements according to project needs.
  • We coordinated architecture, structures, MEP, drainage, and tunnel disciplines for clash detection and resolution using Navisworks, improving integration and reducing interference risks.
  • We exported and reviewed deliverables (IFC, NWD, RVT, and DWG) for the client, ensuring correct information transfer and compatibility with the client’s systems.
  • We automated documentation and model export processes using Dynamo, streamlining workflows and reducing document and model delivery times.
  • We improved interoperability between Civil 3D and Revit (e.g., Civil 3D tunnel as in-place family in Revit), facilitating integration between both programs and ensuring model consistency.
