Hull Coop


    The Rundown

    Hull Coop is a farmer-owned supply cooperative in Hull, Iowa that began as a grain elevator in 1908 by a group of local farmers who saw a need within their rural community. Hull Coop has continued to expand over the years, and due to business growth and capacity, they needed a new bulk fertilizer storage facility.

    The new building will protect the salt supply.

    It will be protected from being compromised by wind and precipitation. Once the general contractor completed the footings and floors, Legacy installed the fabric building very quickly, in about two weeks. It was a very positive process with professional communication between Legacy and Dewberry throughout the project.

    Legacy was very easy to work with.

    The old buildings used tubular steel, and no matter what you do, the salt gets inside the tubes and corrodes them. They came out here with their crew, rented all their equipment, and erected the buildings in three weeks flat – a week ahead of schedule. It's a stand-up company.

    The Legacy construction crew was very professional and courteous.

    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. They finished the job well ahead of schedule, worked safely, and followed our stringent safety requirements to the letter.
