Here's a link to the engineering report.
The structure consists entirely of reinforced concrete(columns, core, sheerwalls, floorslabs), with the exception of some of the outrigger trusses on the mechanical levels. It's similar to some of the Dubai marina towers, particularly Princess Tower and Marina 101, although it will have more outrigger trusses.
