Structural Steel Design Award, Commendation

RISE, Belfast | Wolfgang Buttress

The design consists of two concentric geodesic spheres supported on a bed of steel "reed" columns - a reference to the marshlands previously on the site. The smaller sphere is suspended within the larger 30m diameter sphere by unobtrusive pre-tensioned galvanised wires.
More than 4,000 mild-steel tubular components were connected with around 10,000 bolts. Components were standardised into fewer than 60 types, including a dish-like node with a variety of holes to cater for all interfaces. The entire structure is powdercoated in brilliant white. 
The judges praised Rise's impressive geometric form and precision, and its complex assembly delivered on a busy site in the middle of a major roundabout.
