MasterCard Builds St. Louis Headquarters

ST. LOUIS -
MasterCard has built a new 550,000-sf global technology and operations headquarters in suburban St. Louis. To ensure that the three four-story office wings accommodate changes in MasterCard's technology and business, architect HOK designed 35,000-sf open floor plates that are easy to reconfigure. The three-story data center includes a heavily reinforced concrete structure, no windows, "2 (N+1)" power redundancy, an uninterruptible power supply system, a reserve water system, and a "preaction" fire protection system. The plug-and-play computer infrastructure allows for easy expansion.
