24 more stories coming to Blue Cross building | Chicago Tribune
In an unusual corporate expansion, Blue Cross and Blue Shield of Illinois will add 24 floors on the top of its headquarters on East Randolph Street to accommodate the health insurer's rapid growth.At a cost of $270 million, Health Care Service Corp., parent of Blue Cross and Blue Shield of Illinois, said Tuesday that construction will begin early next year at 300 E. Randolph, the dual headquarters of the Illinois Blue Cross division and Health Care Service, pending approval of various permits.
The existing 33-story building already has 30 floors above ground on prime real estate located just east of Aon Center on the northern edge of Grant Park....
The building is now 466 feet high from its base and will rise to an estimated 796 feet.
The structure was originally designed by Chicago architect James Goettsch to accommodate 24 additional stories to meet an expected need for more office space, the insurer said. Thus, the skyscraper will reach its designed height of 57 stories upon completion in 2010.
