American Cancer Society Center

The American Cancer Society Center is a large convention center and office building in downtown Atlanta, adjacent to Centennial Olympic Park. The building contains about 1,500,000 square feet (140,000 m²), including a partially underground parking garage and loading area. The building, originally called the Inforum Technology Center or Inforum, was designed by the prominent Atlanta architect John Portman, who previously designed the AmericasMart buildings.

ACS Center is connected via two indoor pedestrian bridges to the ground abyss of the AmericasMart building 3, across Williams Street to the east. In addition to housing the National Home Office and South Atlantic Division of the American Cancer Society, the Center also provides office space for AT&T, InComm, Internap, Turner Broadcasting System, and US South Communications. Fiber optic connectivity is available throughout the structure.

The lower levels (Ground and Mezzanine) consist of meeting and conference rooms, a few business offices, and a 450-seat, two-level theater. The Bridge level (with 22-foot (6.7 m) high ceiling), above Mezzanine, houses Park View Café, a cafeteria-style breakfast and lunch restaurant, and Internap. The Bridge level was originally named Expo, and consisted mostly of convention floor space, requiring a very high ceiling. Most of that space, including the inactive passenger bridge, is now leased by Internap, housing telecommunications equipment and office space. Six floors of office space sit above Bridge, spanning only part of the building's north-to-south distance. Office floor 1 is also named Atrium.
