The challenge
The equipment list drives everything on a building like this. A combine head and a folded sprayer boom set the door widths, the door heights set the eave, and the eave and span set the frame — get that order backwards and you own a building your machinery does not fit through. The pad also sat across a gentle slope, which sends every storm toward the slab, and an uninsulated roof over a cold slab drips on stored equipment all winter.
