Port Authority issues milestone report on WTC rebuilding

Written by 

The Port Authority of New York and New Jersey released its latest quarterly milestone report announcing that it has met 19 of 20 second-quarter 2009 rebuilding milestones. Milestones for the second quarter included: the installation of more than 2,400 tons of steel for the National September 11 Memorial & Museum, the equivalent of 20 Statues of Liberty; the installation of 1,250 cubic yards of concrete - the equivalent of six miles of New York City sidewalk - bringing the plaza and main entrance of One World Trade Center to street level; and, competitively bid one of the largest and most critical work packages for the World Trade Center Transportation Hub.

The one missed milestone - Complete Approximately Half of Sector 3A Steel over the PATH Line - is substantially complete and will not affect the project’s critical path.


The bistate agency also announced today that it has begun work to meet 24 third-quarter milestones, which will bring most of the western half of the site up to street level for the first time.


Highlights for the third quarter include: the second-to-last installation of structural steel for the entire 9/11 Memorial; the installation of steel columns that will support the WTC Transportation Hub’s roof over the PATH tracks, as well as a major Hub contract for the construction of Greenwich Street and the permanent support of the No. 1 subway line; and, the completion of the street-level plaza that surrounds One World Trade Center. The report also lists 19 milestones the agency has set for the fourth quarter of this year.

* Complete Fabrication of the Remaining Calatrava Arches for the East-West Connector.
