Marlins Ballpark

Retractable Roof

The retractable roof at Marlins Ballpark protects against rain, the blazing sun, and other adverse weather conditions when closed, and creates a completely open-air stadium when open. Florida baseball fans can enjoy the sunny, welcoming weather of the Miami area, but be sure they will be safe from rain cancellation or getting soaked when the Gulf weather begins to stir. With unmatched technology, Marlins Ballpark operators and owners can be sure their facility will keep fans coming back -- and will keep the game going -- rain or shine.

The staff of Uni-Systems Engineering designed, supplied, and installed the electro-mechanical drive system for the Marlins Ballpark retractable roof. The roof is made of three stacking panels: one large upper panel and two smaller lower panels which rest below the upper panel when the roof is fully retracted. The roof is moved by a single individual in a control room. A collection of sensors and feedback/diagnostic systems reports on the roof progress and monitors conditions of the roof panels and mechanization to ensure safe operation. The retractable roof design includes a tie-down system that secures the retractable roof in hurricane wind forces.

The work of Uni-Systems Engineering staff also included the design, supply, and installation of the Marlins Ballpark home run celebration feature, the design of the operable outfield wall structure and mechanization, as well as the design and supply of the retractable roof seal system.
