Above, the main hoists of the Assembly Building, capable of handling loads of up to 1,500 tonnes. On the shop floor, some of the specialized tooling required to assemble, lift and finally manoeuver ITER's supersized components.
Adjacent to the Tokamak Complex, the Assembly Building will be the location for pre-assembly activities on the massive components of the ITER device before they are transported to the Tokamak Pit for installation. This vast workshop will host custom-made tools as well as two 750-tonne cranes that will travel the length of the Assembly and Tokamak buildings.

Here, for example, each of the nine steel sectors of the ITER vacuum vessel will be sub-assembled with thermal shielding and two toroidal field coils before being lifted and positioned inside the machine.

Work on the external structure began in June 2012 and was completed in September 2015 with the lifting of the massive 730-tonne roof structure. Two 750-tonne overhead cranes and two 50-tonne auxiliary cranes were installed in 2016 and today, commissioning is underway on the largest cranes. Once the temporary wall separating the Assembly Hall from the Tokamak Building is removed, the crane rails will be extended to over the Tokamak assembly pit.

Work has been underway since June 2017 to install the building's first assembly equipment—the vacuum vessel sector sub-sector assembly tool. The second tool will be delivered in 2018.
