The Bin Erection crew showed up Monday the 15th to start the metal work.  Here they are working on the roof vents.

These are the sheets that make up the rings of the bin.  It will take 15 rings of sheets to finalize the bin.  Each layer of sheets is equal to 1 ring of the bin.

This is actually going to be the top ring of the bin.  As construction continues, new rings will be added then jacked up so they can add on the next one.
