12 Years On, Ground Zero Rises Again


From the spire to the Oculus, construction at the World Trade Center site in New York City is in high gear on the 12th anniversary of the Sept. 11 attacks.

Project updates and developments on the 16-acre World Trade Center site in Lower Manhattan are posted on the Port Authority of New York & New Jersey website and on its Facebook page.

Updates regarding progress at the September 11 Memorial & Museum are available at www.911memorial.org.

Construction highlights and project details are provided below.

One World Trade Center

Set for completion in 2014, One World Trade Center now towers above the New York City skyline, reaching 1,776 feet—the tallest building in the Western Hemisphere and the third tallest in the world.

“Designed by renowned architect David Childs, of Skidmore, Owings and Merrill, LLP, One World Trade Center incorporates new architectural and environmental standards, setting a new level of social responsibility in urban design,” according to officials.

Reaching 1,776 feet, One World Trade Center is the tallest building in the Western Hemisphere and third tallest in the world.

When complete, the building will reportedly include 3 million square feet of office space on 71 office floors, a grand public lobby, and an observation deck.

A sneak peak at the three-level observation deck, which will reportedly open in 2015, can be viewed in this video.

A progress update posted on the WTC Progress Facebook Page indicated that the podium wall installation was completed on Monday (Sept.  9).

Spire Installation

Crews installed the final sections of the 408-foot steel spire at One World Trade Center in May.

Workers installed the spire atop One World Trade Center at dizzying heights.

During the installation, ironworkers set and tightened 60 bolts at an altitude of 1,701 feet, officials reported.

Also in May, officials reported that the building was more than 55 percent leased with tenants including Condé Nast, which has leased nearly 1.2 million square feet to house its global headquarters; Vantone China Center; and the U.S. General Services Administration.

The building is designed to be one of the safest commercial structures in the world, officials said.

Transportation Hub

Meanwhile, arches of the Oculus—the future World Trade Center Transportation Hub—have been lifted by cranes as ironworkers set the pieces in position for welding.

Transportation Hub

When complete in 2015, the Transportation Hub will serve 250,000 daily commuters, officials say.

Scheduled for completion in 2015, the 800,000-square-foot Hub will serve 250,000 daily commuters and millions of annual visitors, according to officials.

The Oculus was designed by Spanish architect Santiago Calatrava.

In late August, workers installed ceiling grids that serve as a structural suspension system for lay-in ceiling panels below the bridge in the East West Connect portion of the Hub.

Museum Progress

After years of delays stemming from financial disputes, the 9-11 Museum is set to open in spring 2014, officials report.

To date, 24 large artifacts have been installed inside the museum constructed to remember and honor the 2,983 people who were killed in the attacks of Sept. 11, 2001, and Feb. 26, 1993, according to a Sept. 6 announcement by the National September 11 Memorial & Museum officials.

Designed by architect Michael Arad and landscape architect Peter Walker, the museum will feature a “slurry wall,” a surviving retaining wall of the original World Trade Center that withstood the devastation.

The museum is located underneath the eight-acre memorial plaza, which opened to the public on the 10th anniversary of the attacks, Sept. 11, 2011.

Other Tower Updates

The developers of 4 World Trade Center—a 72-story, 977-foot building—say it will open in November. The Port Authority will be the main tenant.

Construction on 3 World Trade Center is scheduled for completion in 2016, but the developer (Silverstein Properties) is required to lease 400,000 square feet of space before completion, according to reports. Now seven stories tall, the building is expected to climb to 80 stories and 1,150 feet.

The 88-story 2 World Trade Center planned for the site’s northeast corner will not be built until the commercial real-estate market improves, reports say.
