NEW YORK — The silvery 1,776-foot skyscraper that rose from the ashes of Sept. 11 to become a symbol of American resilience opened for business Monday, as 175 employees of the magazine publishing giant Conde Nast settled into their first day of work in their new offices.
One World Trade Center's official opening marked a symbolic return to some sense of normalcy for the site where the twin towers toppled more than 13 years ago.
"The New York City skyline is whole again," says Patrick Foye, executive director of the Port Authority of New York and New Jersey, which owns both the building and the 16-acre World Trade Center site.
Steps away from the new tower are two memorial fountains built on the footprints of the decimated twin towers, a reminder of the more than 2,700 people who died in the terrorist attack.
Conde Nast, publisher of Vogue, the New Yorker and Vanity Fair, is expected to move in about 3,000 more employees by early next year, eventually occupying 25 floors of the nearly $4 billion, 104-story tower, the nation's tallest building.
Amid Monday's celebratory tour of parts of 1 World Trade Center, Conde Nast officials declined to comment on employees' possible fears about working in the new building.
Foye counters that it's "the most secure office building in America." And its chief architect, T.J. Gottesdiener, said the high-rise was built with steel-reinforced concrete that makes it as attack-proof as possible — much stronger than the original towers, which collapsed on themselves when the hijacked planes hit.
The stairwells are built with a hardened concrete core and are wider to allow firefighters to move while people exit. The building's mechanical systems are also encased in hardened concrete.
"If my son told me he had a job in the trade center Tower 1, I would have no qualms about him being there," Gottesdiener said.
After Sept. 11, he said, architects took pains to figure out new ways to make a high-rise safer, working with the New York Fire Department, buildings officials and police, while learning from new techniques from construction in cities worldwide.
Finally, computerized simulations were used to calculate what would happen with people in the building.
One World Trade Center is 60 percent leased, with another 80,000 square feet going to the advertising firm Kids Creative; the stadium operator Legends Hospitality; the BMB Group investment adviser; and Servcorp, a provider of executive offices.
The government's General Services Administration signed up for 275,000 square feet, and the China Center, a trade and cultural facility, will cover 191,000 square feet.
The space is at the top of the global price range, at $69 per square foot below the 63rd floor, and $80 to $100 going up.
The eight-year construction of the skyscraper came after years of political, financial and legal infighting that threatened to derail the project.
The bickering slowly died down as two other towers started going up on the southeast end of the site: the now completed 4 World Trade Center, whose anchor tenant is the Port Authority, which started moving in last week, and 3 World Trade Center, which is slowly rising.
The area has prospered in recent years. About 60,000 more residents now live in the area — three times more than before Sept. 11 — keeping streets, restaurants and shops alive even after Wall Street and other offices close for the day.
Still, it's a bittersweet victory, one achieved while haunted by the past.
"The city and the world were watching us, and we had to do it right, to do it better than before," Gottesdiener said. "And we did it, we finally did it."
