PROJECT OVERVIEW

The Battery Atlanta has been developed to be the South’s preeminent lifestyle destination. Anchored by SunTrust Park, the new home of the Atlanta Braves™, The Battery Atlanta™ is a sports and entertainment experience unlike any other. Conveniently located at the intersection of I-75 and I-285 in the bustling Cumberland area, The Battery Atlanta™ offers an entertainment experience 365 days a year, not just on gamedays. The 1.5-million-square-foot mixed-use destination was designed to be a live, work, shop, dine experience.

On behalf of the Atlanta Braves, executives at Populous, who designed SunTrust Park, worked closely with the team at Wakefield Beasley & Associates, who designed many of the related structures, and Jerde Partnership, which produced the master plan. The 57-acre site consisted of an oblong, mostly undeveloped property (due to utility pipelines running underground) near a major highway interchange.

PRECAST SOLUTION

Precast concrete architectural and structural components helped to achieve some of the designers’ key goals at the stadium that serves as The Battery’s focal point.

Precast concrete was chosen due to its long-term durability, cost, and fast construction. Gate Precast Company in Monroeville, Alabama, produced the architectural precast concrete panels, while Metromont Corporation in Hiram, Georgia, fabricated all of the structural precast concrete stadium components.

The stadium is clad with architectural precast concrete wall panels, many inset with thin brick, in complicated formats that often challenged the structural design. Using the panels offered a panelized system that could be erected quickly while providing the masonry aesthetic desired. It also provided an easily reproduced concept for WBA to use on nearby structures, where it was featured on wainscoting, planter caps, and decorative features.

The embeded thin-brick precast concrete panels, which feature a three-brick color blend, were complemented by two additional finishes. Some panels were cast in a buff color with a light sandblast to replicate limestone, while others have a formliner-cast appearance to replicate chiseled stone. Some of these panels also were used on the interior, especially at field level, to pull the exterior look inside.

Massive Excavation Needed
The ballpark’s location on the side of a wooded hill required significant excavation of soil and rock, with the stadium entry being 35 feet below the grade found near the outfield walls. As a result, the soil height varies continuously, requiring the hybrid concrete-and-steel structural frame to be supported at the bottom of the excavation, isolated from the adjacent soil.

Floor-to-floor heights were as tall as 35 feet in some locations, requiring brick-clad panels weighing as much as 56,000 pounds. Typically, the panels would be supported at grade and connect laterally at each floor level. This wasn’t possible due to the ballpark’s isolation from the soil, requiring they be supported by the elevated ballpark structure.

Stadium entries feature large trusses spanning the space, supported by precast concrete columns at each end. Connecting the trusses to the precast concrete components, and then connecting the precast to the structure, created an additional challenge. The precast not only had to resist gravity, seismic, and wind loading of the trusses but also expansion and contraction forces.

Carving the ballpark into the side of a hill on sloping ground created challenges for the seating design and interiors. Metromont fabricated a range of structural components, including multiple depths of tread-and-riser sections, tub sections, raker beams, columns, stairs, flat slabs, and walls.

Raker Beams Supported
Very little of the seating bowl was built on grade, so the precast concrete rakers had to be supported everywhere. In some areas, raker beams support other rakers, while others are set on solid slabs, vomitory stairs, and many precast elements are supported on steel beams.

To pull seating sections in the 41,149-seat stadium as close to the field as possible, seating risers varied in size every few levels. Depths of 33, 36, 48, and 72 inches were specified, along with tub sections in single-, double-, and triple-level configurations, although triple seating units were used the most to minimize piece counts and picks.

Uniquely, each stadium seat faces the center of the field, with a cantilevered design that places all columns behind the seats. Virtually all of the seats are riser-mounted rather than tread-mounted due to the risers’ profiles, and allowing easier cleaning and maintenance.

Coordinating all these venues created daunting challenges, but the result has been a signature mixed-use development for the city.
