Build progress at ground zero

STRUCTURAL steel for the 1,776ft tower that will be known as 1 World Trade Centre has risen 200 feet above street level in a tangible sign of ground zero progress since the September 11 2001 terror attacks.

Workers are now installing 16 steel nodes on the 20th-floor level which serve as joints between the steel framing for the building’s podium and the steel for the rest of the tower.

The 104-storey skyscraper is due to be completed on the 16-acre trade centre site in 2013.
