Tetrahelix Engineering
1. The internal steel structure is engineered to secure the piece to the foundation in earthquakes and heavy winds.
2. The "weaving" of the steel inside the bronze was accomplished by building the original wax sculpture around a foam model of the triangulated steel structure.
3. The lower section of the bronze was cut off and dissected, thus allowing the steel [painted white] to be interlaced and welded inside the bronze.
