Granfoss Tunnel, Oslo

23 november 2016

The fire protection of the second tube in Granfoss was finished at beginning of November which concludes our works on the project that had started in March of this year. We installed fire protection boards on the ceiling and upper part of the walls in approximately the first 100m of the tunnel from both ends. The ends consist of concrete tunnel lining while the middle part is rock tunnel. It was a pleasure to work with Skanska Norway and we hope to come back for more projects.
