In 2019 Structures worked alongside Novak Construction and Frattalone Companies to build one of the largest Earth Retention systems in the Twin Cities. The new Costco Wholesale once a 166,800 square foot piece of land filled with varied topography, is located on the SE of the interstates 494 and 35E interchange in Eagan, MN. Expected to provide over 250 jobs, Costco is a great addition to the Eagan Community.


It was critical that the site was pad ready in 75 days. To do this, Major excavation and 52,638 ft of multiple segmental retaining walls were needed to be build. One of those walls was designed to run parallel with Blue Gentian Rd and reach 30 feet tall and over 1,000 feet long.


The experience of the Structures team and strong field communication with all involved parties, Structures was able to deliver the challenge of providing a site ready surface for Costco’s amenities and achieve the crucial deadline for Novak Construction.
