What to do about Chicago's embarrassing Big Dig?

The Chicago Spire, a 150-story tower condo tower, was designed by Santiago Calatrava for a site overlooking Lake Michigan. The cocky, corkscrew shaped building was expected to cost more than $1 billion, which, even for Calatrava (whose projects have been known to go over budget), was a lot. But the developers ran out of money, and all they have to show for their efforts is a giant hole -- 76 feet deep and 110 feet in diameter -- in the ground. (Calatrava says he is owed more than $11 million for his design work.)

So what's to become of the hole, a literal architectural depression? The Chicago Architectural Club is asking architects (and architecture students) to put on their spire-shaped thinking caps. "Once the motor of real-estate speculation has stalled, what can we use to propel ourselves, and the discipline, forward?" asked the Club, announcing an international competition. Blair Kamin, a Chicago architecture critic, asked the same question on his blog last year, and the answers came pouring in.
