Hexagon’s technology guides Skanska in building the world’s most ambitious road tunnel

Highlights:

  • Skanska reduces time, cost, and emissions through first-time-right accuracy
  • Hexagon delivers precision surveying for the world’s longest and deepest road tunnel
  • The decades-long partnership is driving advanced digital innovation in infrastructure

Hexagon, the global leader in measurement technologies, is supporting one of the most ambitious infrastructure projects in the world, equipping Skanska with surveying solutions needed to construct Project Rogfast, a 27-kilometre subsea tunnel that will be the longest and deepest of its kind. 

Running 392 metres below sea level, the tunnel will connect the cities of Stavanger, Haugesund, and Bergen, helping to cut travel time by 50% and strengthening economic links in the oil and gas sector. Skanska integrates Hexagon’s geospatial and construction solutions to deliver the project accurately, safely, and sustainably.

Project Rogfast poses extraordinary engineering challenges, including tunnelling from both ends to meet within a 5-centimetre margin of error. Even a small misalignment can cause massive rework and waste. Hexagon’s portfolio of Leica Geosystems solutions ensures every surveyor, excavator, and drill operates with high-confidence accuracy, allowing the project to proceed without interruption.

Hexagon’s technologies are delivering measurable impact across the project by:

  • Enabling precise alignment with total stations, GPS, multistations, and laser scanners
  • Reducing rework, emissions, and cost through real-time data capture and validation
  • Powering safe operations under extreme conditions, 392 metres below sea level

“In a project like this, even a millimetre of misalignment can trigger cascading risks,” said Trond Valleur, Vice President, Skanska. “Hexagon’s technology gives our teams the confidence to move forward with accuracy, efficiency, and safety. That precision, and our shared drive to push boundaries, is what makes this partnership so powerful.”

“This project is a milestone for infrastructure and a testament to how measurement technologies are reshaping what’s possible,” said Burkhard Boeckem, CTO, Hexagon. “We’re proud to support Skanska with solutions that enable their teams to work smarter and safer with accuracy.”

The tunnel also represents the strength of Skanska and Hexagon’s 30-year partnership, rooted in innovation and shared ambition. Skanska teams use a wide array of Hexagon tools, including the Leica RTC360, Leica MS60 MultiStation, Leica AP20 AutoPole, and Leica TS60, the world’s most accurate total station.

Together, Skanska and Hexagon are shaping the future of infrastructure, combining digital excellence and construction expertise beneath the sea.
