The new World Trade Center may well be the most complex, demanding and detailed construction project ever attempted. It is a series of contradictions. The vision behind it requires a place to remember as well as to welcome the future.

It calls for both an open, inviting layout and safety measurements above and beyond the highest standards. It took the best and the brightest architects, engineers, city planners and other experts to create the plan in progress today - a plan that not only meets these complicated requirements but brings ideas that were once contradictions into seemingly impossible harmony.
