Legacy designed, manufactured and constructed a fertilizer storage building for Tronson Grain up in Crary, North Dakota. Patrick Tronson, assistant manager, describes the building as simple with a big footprint, but it's anything but simple. The floor of the storage building is poured concrete with a pit in the middle. Then there are multiple storage bins separated by precast concrete walls. The attached tower is probably the most imposing feature. It's a 150-ton capacity automated loading and mixing machine.
