The new Skanska HQ is under construction in Helsinki. Today, the 200 square meter atrium roof, weighing 42.000 kilograms, was lifted to its place with a special crane brought to the site for this purpose only. The atrium roof was built ready on the ground, down to the ceiling panels. This took two months; lifting it to its place, on top of the 8th floor, took only two hours. All parties involved in the project came to see this unusual event.
