Default Public Art submissions: Sculpture for Traffic Islands in a new city development

This journey started with rescuing from the scrap in in the steel fabricating plant doing work for me. I thought that the 1/8" steel rods used to weave a material in a decorative fence, could be repurposed as central lines for making curves in a sculpture. So I ignored the waves and just worked with an imaginary smooth central curved axis.

I fixed one end in a plank of wood by epoxy-gluing it into a drilled hole I made. Then with pliers and the radius of various cans, jars, buckets and the like, I curved the steel to follow a sketch I had made using 3 strands, each 5t long. At the end of the process, when things were balanced, I epoxied the free ends of the 3 steel rods into the plank and I had a maquette, with the working name, "Partners"

For the first sculpture, I enlarged the work 2:1 measuring by hand the dimensions and using the strength and endurance of several skilled iron workers to reproduce my maquette in solid 1" steel. I was scared of using steel tubing, for fear that sharp bends might cause the walls to collapse. See the process, here. Now I studied the forms and what resonated with me was the interaction of the two forms facing one another. They were in conversation, so that, necessitated my change of name and that new name belongs!

Then I decided to enlarge the work 6 to 8 times using 6" or 8" steel tubing and tons of steel. That required reverse engineering. So I purchased a Structure Scanner attachment for an iPad Air II and then scanned the sculpture sending it wirelessly to a software program, Skannect in my Macbook Pro.
Then I sent the form I generated as a .STS file to a company that could extract the central line of the complex curves and generate the exact curves from which to rebuild the exactly 1" steel tubing as so generating a machine file to be scaled up for job estimating by a large industrial fabricator to work in 6" or 8" steel.

So now the work is out to bid and the project will be submitted to a competition.......with the following renderings in massive versions.....

If made 8x current size, it will span 40ft and be 12 ft wide and 21ft high, using some 240 ft of stainless steel pipe! Has to withstand heat and cold and rain as well as really strong winds!! This is fun!
