GROUND ZERO is a buzzing hive of activity ' cranes and construction everywhere, crowds of tourists and vendors. Projects are shaping up, too. David Childs's One World Trade Center (WTC) ' the erstwhile 'Freedom Tower' ' has passed 78 stories en route to 104, the Fumihiko Maki tower at the southeast corner of the site is more than 30 and heading for 72, and the National September 11 Memorial opens this month.
Although Santiago Calatrava’s bony train station — morphed by budget cuts, according to wags, from bird to stegosaurus — has yet to emerge from the ground, it remains the only piece of architecture with any real ambition on the site. But its price tag — about $3.4 billion — strikes some observers as a tad dear.
