Chicago’s lawmakers on March 29 approved local developer Christopher Carley’s plan for the Fordham Spire, a 2,000-ft-tall hotel and condominium tower sited at the mouth of the Chicago River. The proposed 920,000-sq-ft, slender skyscraper is designed by architect-engineer Santiago Calatrava. The 124-story project gained approval from city planners on March 16 (ENR 3/27 p. 10). Chicago-based Walsh Construction has been hired to build the $550-million structure, scheduled to open in 2010.
