Structural steel for the 1,776-foot tower that will be known as 1 World Trade Center has risen 200 feet above street level, a tangible sign of ground zero progress, redevelopment officials said Wednesday.
Workers are now installing 16 steel nodes on the 20th-floor level, Ward said. They serve as joints between the steel framing for the building's podium and the steel for the rest of the tower.
The 104-story skyscraper is scheduled to be completed in 2013.
Work is also proceeding elsewhere at the trade center site, Ward said, as the Port Authority's commissioners held their monthly meeting on World Trade Center rebuilding.
"What people can't see ... is over 600,000 square feet of museum space being built below grade,'' he said.
The commissioners approved contracts for several projects, including a contract with New York-based DCM Erectors for installing the bronze that will be inscribed with the names of those who died at the twin towers on Sept. 11, 2001.
