Plans for a 315,000 square-foot data center facility on Chicago’s Near South Side are moving forward, with city approval clearing the way for design and construction. The development team has set a goal of fall 2010 to begin construction, with a potential completion date of late 2011. The six-story building will be 315,000 square feet, with 143,000 square feet of raised floor area. Preliminary plans call for a reinforced concrete structure, with 18-foot ceiling heights, heavy floor loading, space for full generator backups, and heavy-duty, high-efficiency cooling systems.
