Ground Zero’s 540m tower starts to soar skywards

Structural steel for the 540m tower that will be known as 1 World Trade Center has risen 60m above street level in a tangible sign of progress at the Ground Zero site in New York.

“This progress is one more sign that the site is not a pit anymore,” said Port Authority of New York and New Jersey executive director Chris Ward. The authority owns the 64,000m² site.

Workers are now installing 16 steel nodes at 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 in 2013.

Elsewhere at the site of the Twin towers terrorist attacks of 2001, work is underway below ground. “What people can’t see … is over 64,000m² of museum space being built below grade,” he said.

  • Over 1000 architects and engineers have now signed a petition calling for a new investigation of the three collapses on 9-11, WTC1, 2 and 7. No adequate explanation exists of the mechanism triggering collapse, neither is the propagation of the collapse explained in a nmanner consistent with the basic principles of mechanics.

    Collapses at virtually free-fall speed ocurred, impossible in a progressive collapse situation as it is the forces caused by decelaration of the falling body that causes progressive damage.

    Forces also act in pairs, meaning that the both the falling body and the section of tower below would be damaged, contrary to the explanation of the collapse currently on offer

  • This will be a beautiful building. The delays in finishing the projects ie. Freedom Tower, are a little hard to believe.
