Lucas Oil Stadium

Retractable Roof

Lucas Oil Stadium is home to the NFL's Indianapolis Colts, and host for NCAA men's and women's Final Four, as well as major conventions, trade shows and events. The stadium's 180,000-square-foot pitched retractable roof follows classic field house and industrial  designs that are seen throughout Indianapolis. When closing, the two retractable roof panels climb a 13-degree slope along five rails mounted to exposed steel trusses. The panels meet to form the peak of the roof, which is then covered by a mechanized weather-tight ridge seal. The result is a traditional pitched roof that protects the interior from wind, rain, and temperatures.

The staff of Uni-Systems Engineering designed, supplied, and installed the electro-mechanical drive system for the Lucas Oil Stadium retractable roof. The cable drive system moves the panels between the open and closed positions in approximately 11 minutes. The roof is operated using a personal computer located in the control room.

Uni-Systems Engineering staff also designed, supplied, and installed the operable end zone wall.
