Post/ENR World Trade Center Project's Shape Is Challenging To BuildThe complex above-grade form of Santiago Calatrava's WTC Transportation Hub, designed to resemble a bird of peace, is taking shape in Lower Manhattan. The main transit hall, which is 365 ft long, will contain more than 11,000 tons of structural steel in 600 members, some with as many as three field-welded connections. Challenges include the unique geometry and the connection engineering. The entire structure was modeled to determine a carefully staged erection sequence. The hub is scheduled to open some time next year. EPA Proposes $1.7 Billion
