The Rundown

This bulk fertilizer storage building has a capacity of over 27,000 tons of fertilizer contained in six concrete bins. The lean-to provides a separate area for logistics and transloading to facilitate six turns per year.

Customer Success

“We have really bad soil conditions here. Because of our soil issues, we simply couldn’t afford to construct a more traditional building. The concrete costs made a more traditional building cost prohibitive. The lightweight design of our Legacy building allowed us to reach a compromise between soil conditions and cost. Regarding the design and construction phases of the building, I can say that the process went exceptionally well. When I made eleventh-hour changes to the job, Legacy handled them with ease. The Legacy construction crew was very professional and courteous. They finished the job well ahead of schedule, worked safely, and followed our stringent safety requirements to the letter.”

Joe Bitter | Alliant Energy/IEI Barge Services

“The building surprises you. In the winter it feels warmer and there’s no wind, and in the summer it feels cooler. It’s more comfortable inside the building almost all the time. I’ve literally never been inside a fertilizer shed that was vented this well. Even during the summer, we don’t have the slimy floors from humidity inside.”
