HexagonSkanska Rogfast Tunnel

Carving a tunnel beneath Norway’s dramatic fjords is no ordinary engineering feat. At over 27 kilometres long and 390 metres below sea level, the Rogfast tunnel will become the world’s deepest and longest undersea road tunnel — a project defined by precision, endurance, and trust in technology.

To achieve it, Skanska has turned to Hexagon’s advanced surveying and positioning systems — tools that make the invisible visible, guiding teams through rock and water with millimetre accuracy. From real-time monitoring to data-driven decision-making, Hexagon’s technology ensures that every blast, bore, and breakthrough happens exactly as planned.

Palladian was commissioned to create a film that captures this extraordinary process — not just the scale of the engineering, but also the millimetre precision required. The result is a story of innovation beneath the surface: how data, determination, and design come together to shape one of the most ambitious infrastructure projects in Europe.
