PORT AUTHORITY RELEASES THIRD QUARTER MILESTONE REPORT ON WORLD TRADE CENTER REBUILDING

Date: Nov 09, 2009
Press Release Number: 140-2009

Memorial Steel Installation Nearing Completion; Work Under Way to Build One World Trade Center To 20th Floor Equivalent Level in First Quarter of 2010

The Port Authority has met 21 of 24 World Trade Center rebuilding milestones, according to its latest quarterly milestone report, released today.

Milestones for the third quarter included: the installation of 12 of 24 70-ton, 60-foot-high jumbo perimeter columns for One World Trade Center (all 24 columns were installed by October 31); the start of work to install 694 pieces of steel to fill in the last major section of the National September 11 Memorial & Museum; and the award of a major construction management contract to Tishman/Turner Construction for the World Trade Center Transportation Hub.

Upcoming milestones include construction of One World Trade Center to reach the 20th floor equivalent level in the first quarter of 2010.

Of the three missed milestones, two are within the Port Authority’s control. The Port Authority has developed complete mitigation strategies for those two milestones in order to avoid future delays. The third missed milestone - the demolition of 130 Liberty Street - is under the purview of the Lower Manhattan Development Corporation and Lower Manhattan Construction Command Center. The Port Authority is currently reviewing the impact of the missed milestone on construction of the Vehicle Security Center, part of which must be built where 130 Liberty Street currently stands.

The major milestones were established as part of the World Trade Center Assessment, a comprehensive review of all of the major public projects on the World Trade Center site. It was released in October 2008. The Port Authority has since been issuing quarterly reports so the public can track the rebuilding progress and challenges along the way.

Today’s report can be found at www.wtcprogress.com.

Highlights for the third quarter include:

Installed approximately 750 tons of steel for the National September 11 Memorial & Museum - enough for six Statues of Liberty.

Installed more than 17 miles of electrical conduit for the National September 11 Memorial & Museum.

Awarded a major contract for one of the most critical work packages for the World Trade Center Transportation Hub - the Greenwich Street Corridor/Underpinning of #1 Subway Line.

Installed four additional Calatrava arches in the East-West Connector, bringing the overall total to 51.

Installed 1,500 tons of structural steel for One World Trade Center, including 12 of 24 supercolumns that form the perimeter of the tower.

Installed 10 slurry panels totaling 1,500 cubic yards of concrete and 250 tons of rebar for the Vehicle Security Center. A total of 18 slurry panels have been installed to date.

Port Authority Chairman Anthony R. Coscia said, “While we continue to make progress on the public projects at the site, we also realize we have many significant milestones ahead. We’re committed to tackling the rebuilding challenges to make sure our milestones are met.”

Port Authority Executive Director Chris Ward said, “This kind of tangible progress is critical, but we have many more milestones to meet, which is why we have to work aggressively every single day to hit each one of them.”
