Uni-Systems, LLC is a design, construction, and manufacturing firm located in Minneapolis, Minnesota specializing in kinetic architecture, or movable, mechanized structures.

Uni-Systems has been involved in the construction of five of the seven sports stadiums incorporating retractable roofs in North America since 1999.

The company was founded in 1968 by Cyril Silberman, CEO, and began extensive work within the aerospace industry[1] including the design and installation of hangar doors, landing gear elevator platforms, empennage stands, and the firm's patented Uni-Dock.

Uni-Systems also designed and installed the Squeeze Play feature, as well as the custom ornamental train that runs along an outfield wall at the stadium.
