Tunnel project services

As Icelandic engineers, we're experts in designing, supervising and strengthening tunnels in demanding terrains. We’ve worked on tunnels through mountains and hard rock, as well as under ground and under water. Our portfolio includes major infrastructure projects that we've designed from scratch, along with existing tunnels that we've renovated. We can also design electrical systems, lighting, telecommunications, operations and control rooms for tunnels. Our tunnel project services cover:

  • Feasibility studies
  • Conceptual design
  • Preliminary design
  • Detailed design
  • Tendering and contracting
  • Supervision
  • Operation and maintenance
  • Independent checking
  • Geological and geotechnical site investigations
