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.

Ma Chi Chen, Ph.D, project engineer, examines the welds, the structural ribs, and the bolting system. The removed sections of the cast skin were then welded over the steel and blended into the surface, hiding the steel inside forever. 5. Jeff Wittman fits the lower portion tight against the upper to weld them back into one piece. 6. David Naisuler hoists the assembled sculpture into its vertical position for Jeff to level the steel "pin". 7. Next, the mating plate will be welded to the pin, which will finally be bolted to the foundation. 8. While the crane holds Tetrahelix in place, Jeff bolts the steel plates together. 9. While the crane holds Tetrahelix in place, Jeff bolts the steel plates together. 10. Through excellence in engineering and fabrication techniques, the sculpture will be standing for generations to come.
