Work on central rebar resumes

Eight months after being interrupted, rebar operations resumed on this all-important area of the Tokamak Complex concrete slab. (Click to view larger version...)
Eight months after being interrupted, rebar operations resumed on this all-important area of the Tokamak Complex concrete slab.
Designing the rebar arrangement for the concrete slab that will support the Tokamak Complex has proved an exceptionally challenging task.

The complexity has been at its peak in the centre of the Tokamak Complex worksite at the location of the future Tokamak Building, where orthoradial (circular) and orthogonal (right-angled) rebar arrangements interface.

In June 2013, as work was beginning on the first 2 layers of rebar out of 16, it appeared that the design in this area needed to be consolidated. Eight months later, the new design was accepted by all parties and rebar laying resumed on this all-important central area on 20 January 2014 .

Completing the complex rebar arrangements will take a few months. Concrete pouring operations in the central area of the Tokamak Building will follow shortly afterward.
