I Am a Hard Worker

So I bought a grain silo back in march, with the intent of either a shed or a garage. 17ft diameter/14ft tall about a 3,300 bushel silo. Not the biggest silo but big enough. It was on a cement slab but no way I was going to move that. It was 18x18ft, too heavy. I have a circle dug up for the foundation footing, I'll fill the rest in later. Tomorrow I'm building the forms for the cement. Hopefully I can pour on Sunday. I have plenty gravel and used siding for the forms and steel mesh and rebar for the foundation. Alot of work but need to get it done before the snow flys! Has anyone else put up a grain silo or grain bin?
