Since September 2014, work is underway on the metal structure of the building. One by one, 12-metre-tall steel pillars are set into place side by side and one on top of the other to reach 60 metres in height. The thickest weigh 23 tons.
On the north side of the work site, two of the five levels of pillar are already in place. Work has just begun on the third level (one third-level pillar is visible in the photo).
