Assembly Building pillars, climbing ever higher

As ITER components arrive on site, their first stop will be the cleaning facility at the entrance of the Assembly Building. Then, in the vast hall of the Assembly Building, they'll be verified and—if necessary—pre-assembled before transfer to the Tokamak Pit for integration in the machine.

The vast, 6,000 m² Assembly Building will house a double overhead crane (with a combined lifting capacity of 1,500 tons) as well as huge custom-built assembly tools capable of manipulating components weighing hundreds of 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). (Click to view larger version...)

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.
