FREEDOM TOWER architect Daniel Libeskind this week explained why it was vital to expose the 'slurry wall' at the foot the New York structure which he has cofidesigned with Skidmore Owings and Merrill. ' The area must be accessible' Libeskind told NCE in this week's New Concrete Engineering supplement.
'We saw the slurry wall and foundations withstood the attack, and now can also see a piece of history of what New York is built on.' Work on the foundations for the Freedom Tower continues apace while the concrete 'slurry wall' which holds back the Hudson River and supports buildings and streets above, is being restrained and an adjacent 9m deep pit excavated. Meanwhile, Ground Zero site owner Silverstein Properties last week unveiled designs for a cluster of three towers around the Freedom Tower. These are designed by British architects Norman Foster, Richard Rogers and Japanese architect Fumihiko Maki. Consultant WSP Seinuk is on the team for Foster's 78 storey 'column free' structure and Rogers' 71 storey tower.
