Situated in front of the start and finish lines with views of the track’s signature Turn 1, the Main Grandstand provides seating for over 9,000 spectators on three levels. The appearance of the Grandstand was generated by performance, efficiency and practicality; the direct relationship between form and function is apparent in the structural expression and modularity of the building’s components. At the Grandstand’s front elevation, a soaring series of red steel pipes frames the building’s two main entrances. To either side of the pipes, a delicate white canopy of nested steel tubes cantilevers 40 feet over a row of concession stands to provide shade and define pedestrian walkways. Bleachers and fixed seats line the track at the ground level, offering phenomenal views of the straightaway and pit lane. Elevated, open-air loge boxes offer private video monitors and personal catering service to spectators. The ground level also hosts offices, kitchens, a loading dock, and restrooms. The second level concourse offers access to the upper risers and the Velocity Lounge, a spacious, double-height entertainment and event space. The lounge’s main feature is a custom-built elliptical bar surrounding a tiered centerpiece illuminated from within by color-changing LEDs. The 29 private suites at the third level share spectacular views of the track and Observation Tower. Accommodating between 20-40 guests, each suite boasts a private outdoor balcony, wet bar and kitchenette, video monitors, and indoor seating area. Overhead, a white canopy sweeps between a series of 50-foot cantilevered steel trusses. In response to the fast-paced and constantly evolving nature of the Circuit of the Americas development, a system of interchangeable pieces was devised that could be arranged according to need. Inherent to this “kit-of-parts” construction system is a flexibility that will allow the Grandstand to grow over time while maintaining a cohesive aesthetic.
