Documenting the Changes to Santiago Calatrava's WTC Building

Some good info from the NY Times about all of the changes that Santiago Calatrava has had to make to his plans for the World Trade Center Transportation Hub over the years as budgets were trimmed and deadlines were made, broken, and made again. Rare is it that you get to see the designs modified out in the open as we have with this ever-troubled project, so it’s interesting to see how things move in slow increments from the architect’s vision to the city budget’s vision.
