Santiago Calatrava, the world-renowned architect, was standing on a street corner the other day, gazing up at the grandest train station New York has built in the past century. High above the plaza of the new World Trade Center, welders were working on platforms suspended between the massive ribs of an arresting steel structure. “They will start mounting glass very soon,” Calatrava said. The most important project of his career was nearing completion — at long last and great cost, to both the government and his reputation.
