Made up of more than 37 million LEDs, the halo video board provides a 63,000-sq.-ft. canvas on which digital media can be presented on one continuous surface in ways previously never imagined. With a size and geometry designed to complement the stadium’s roof opening, the halo form preserves the beauty of the iconic roof.
The support structure needed to accommodate a significant amount of movement, with geometry and details that were similar but never identical.

The structural engineering team used HOK STREAM, a custom-made parametric modeling and optimization tool, to automatically generate the building information model and structural arrangement, including support nodes and their associated stiffness and movements.
STREAM accelerated the process and allowed for quick modifications as the design changed. STREAM also helped the team optimize the structure to stay below the maximum allowable load, reducing the amount of steel by 10 percent (50 tons).
The halo board won an Excellence in Structural Engineering Award from the National Council of Structural Engineering Associations (NCSEA). In addition to working closely on the design with their architectural colleagues, HOK’s structural engineers collaborated with BuroHappold Engineering and Daktronics, which manufactured and installed the video board.

Running along the entire perimeter of the roof opening is a high-definition, 360-degree halo video board that creates a theater-in-the-round experience. At nearly six stories high and one-fifth of a mile in length, it’s the largest video board in any stadium.
