PROJECT DESCRIPTION

A 34m high, 46 tonne sculpture made from 480 lengths of steel stacked one of top of each other. The graceful curve is achieved with straight lengths of steel in combination with precision cutting and assembly. The artist required no visible fixings: this was achieved with a single saddle-shaped looped weld at each of the connections between tubes – an elegant and extremely strong solution.  The design utilised a single CAD model from which STL data for 3d printing of scale models, geometry for finite element analysis, and final cutting instructions were generated in a single-step process – This efficient workflow enabled an iterative process where over forty different designs were produced and evaluated to finesse the final result.
