Skanska was top, moving up from third place in
2023. NFF says the huge jump in activity for the Skanska in 2024 over the prior year was also the highest ever for any company surveyed in Norway on tunnelling activity. AF/Ghella JV move up from 6th place to second. Its
activity level increased over 2023. Haehre dropped from first place to third, its activity
level also dropping. In 2024, Veidekke maintained fourth place, its activity
level nudging up over the previous year. Implenia went from second place in 2023 to fifth
place last year, its activity level dropping in 2024. Metrostav moved up a place to sixth position.
LNS moved down to seventh place from fifth, in 2023.
Its activity level in tunnelling was slightly lower. While drill and blast is the predominant tunnelling
method in Norway. Among the top ranked contractors, during 2024 there were TBMs used by Skanska and the AF/Ghella JV, respectively, says NFF. Skanska was also active with the machines in 2023, it previously noted. Since 2010 there have been more than 15 contractors
active in tunnelling, to some greater or lesser degree, in Norway, according to the NFF figures. Since 2013, except for two years (2014, 2023), the total has been at least 20. The numbers trended up over 2009-2013 and has stayed broadly level since, and recently, even as total tunnelling activity once again closes on highest prior levels.
