In 2014 we built a 20,000 bushel, 36' diameter grain bin. Here is the forms for the pad for our 20,000 bushel grain bin. We have a 2 foot thick concrete footing with a 5 inch thick slab for the bin to sit on. We installed 6 vents on the roof. The top ring has been assembled. The roof is going on. Wall sheets are going on. There are 12 sheets per ring and 6 rings on this bin. Completed. It took 2 days to construct the bin, not including installing the floor and fan. 36' diameter, 22' to the eave. 20,000 Bushel. You can see our 21' diameter, 5000 Bushel bins in the background.   In 2011 we built our first 5000 bushel, 21' diameter grain bin. Here is the pad for our first 5000 bushel grain bin. We have a 2 foot thick concrete footing with a 5 inch thick slab for the bin to sit on. We are assembling the bottom two rings of the grain bin before we start on the roof. The roof is complete. We built some A frame bin jacks and have attached them. We raised the bin up enough to install the next ring. We reset the bin jacks to raise the bin for the next sheet. On the right we are holding the bin up to install the base angle on the bottom sheet. We are filling the bin for the first time.
