Revered Relic of World Trade Center Is Moved

By FERNANDA SANTOS
Published: March 10, 2008


Ozier Muhammad/The New York Times

Workers at ground zero starting to lift the "survivors' stairway" on Sunday. The stairway, an escape route on Sept 11, 2001, was moved to facilitate reconstruction. It will be part of a World Trade Center museum.



Ozier Muhammad/The New York Times

A worker placing a flag on the “survivors’ stairway” on Sunday moments before it was moved, to make way for an office tower.


The steel cables tensed, like a sprinter’s muscles at the start of a race. Then, the crane’s engine roared as the operator pulled a lever, moving the staircase off the ground and 180 degrees from south to north.

And that was how on Sunday the staircase became the last visible remnant of the World Trade Center to be removed from the place where it had stood on Sept. 11, 2001.

The stairs’ relocation marked a brief yet momentous occasion for the engineers who had spent months planning the operation, the preservationists who had spent years trying to save the staircase from destruction and the hundreds of people who had used the steps to flee the complex before the twin towers fell.

It also started a new phase in the rebuilding of Lower Manhattan. With the staircase out of the way, the construction of Tower 2, a 1,278-foot-tall skyscraper, can continue unimpeded, with workers and machinery now free to move about without risking damage to a piece of 9/11 history. Tower 2 is one of the five towers being built at ground zero.

“You were pitting memory and preservation and loss and family against redevelopment and construction, as if you could have one or the other, but you couldn’t coexist,” Avi Schick, chairman of the Lower Manhattan Development Corporation, told reporters at ground zero. “What we proved is in fact they could coexist.”

The staircase will stand opposite a park outside 7 World Trade Center, about 200 feet north of its original spot, until the end of the summer.

Then it will be moved again, this time to the western edge of the 16-acre trade center site, and lowered 70 feet, almost to the bedrock, to where the National Sept. 11 Memorial and Museum will be built, said Joseph C. Daniels, the museum’s president.

At 21 feet high and 64 feet long, the staircase, which has come to be known as the survivors’ stairway for the vital role it played as an escape route, had stood largely obscured, first by debris and then by fencing and equipment.

Its 38 steps, which once connected Vesey Street to the north end of the trade center’s Austin J. Tobin Plaza, were hidden by a thick concrete partition that served as their support. From the street, the stairs could easily be mistaken for a free-standing wall.

In January workers began to chip away at the concrete, and by this month they had extracted the staircase from the bulkhead and the rest of the structure, including a fragment of the Tobin Plaza pavement that remained attached to the top.

The steps suddenly became visible, rising from the dirt into the air.

“If it wasn’t for those steps, I probably wouldn’t be here today,” said Tom Canavan, 48, after watching workers moving the staircase.

On Sept. 11, 2001, Mr. Canavan was working at the Union Bank on the 47th floor of the north tower when the building was struck by a hijacked plane. He fled the office, eventually reaching the trade center’s concourse, where he found himself buried by debris from the south tower’s collapse.

“By the time I tunneled my way out, to the plaza,” he said on Sunday, “the only way I could get out was through the stairway on Vesey Street.”

Hundreds of others are believed to have escaped the trade center site by going down those stairs, said Peg Breen, president of the New York Landmarks Conservancy, one of the preservation groups that worked to save the staircase.

“This a terribly important part of the 9/11 story, a story of survival in the midst of so much destruction,” Ms. Breen said. “It’s a story that we now know will be told.”

In 2006, state officials announced plans to demolish the staircase to make way for the new tower, dismaying preservationists and angering many survivors. The officials said that only one or two of the steps would be salvaged.

Last August, however, the Spitzer administration offered an alternate solution: Move the staircase from its original spot, and eventually reinstall it in the museum, alongside the steps and escalator that will be used by museum visitors.

Preparations for Sunday’s removal had been in the works for three months, said Steven Plate, director of World Trade Center construction for the Port Authority of New York and New Jersey, which owns the site. It involved the removal of the bulkhead and the construction of a steel framework to run beneath the staircase.

Crews used a 500-ton crane to move the staircase, which weighs 65 tons, Mr. Plate said. The cost of the removal is estimated to be $2 million.

The point? I would assume that most people would be really upset to see the staircase broken or harmed, so it's better to be safe. It had as much value as removing the last steel beam, putting the first steel beams up again, or topping out the new towers with their topping out beams.

It now means that there is no piece remaining of the WTC at the site, unless you count the New WTC/below grade parts that will be built over.

Whatever you say, new-person-clearly-in-charge-of-WTC-site's-construction-activity-and-procedures.
What's done is done, and everything seems to have worked out perfectly.

You obviously have never been involved in any construction work. A 500 ton crane can only to lift 500 tons under ideal conditions. Normally it's lifting capacity is much less. The biggest factor determining lifting capacity is the distance the object being lifted is from the center of the crane, but many other factors also come into play. Actually a 500 ton crane for 65 ton lift seems a reasonable. I've done projects where a 700 ton crane was required for a 35 ton load!

Fact:

Larger cranes will be set up and blasting will start THIS month.

So WTC Towers 3 and 4 are 100% U/C now.

NEW WTC TOWERS FINALLY UNDER WAY

By TOM TOPOUSIS

March 13, 2008 -- Construction of two of Ground Zero developer Larry Silverstein's three World Trade Center towers will begin this week when crews start blasting away at bedrock at the recently excavated sites, the developer announced yesterday.

"There has not been this much going on at the site since the cleanup ended in 2002," Silverstein told a luncheon sponsored by the New York Building Congress yesterday.

Silverstein, joined by Port Authority Executive Director Anthony Shorris, said the World Trade Center reconstruction is now throttling up into high gear, with construction beginning on every project within the 16-acre site.

Shorris said that in the coming months, there will be as many as 10,000 construction workers at the site, calling the project "an incredible construction machine."

So far, all the work has been going on 80 feet below street level on bedrock within the World Trade Center's twin bathtubs. But Shorris said the public will begin to see progress in a few months when the Freedom Tower's steel is expected to rise above the street.

By 2010, the Freedom Tower and Silverstein's Tower 3 and Tower 4 between Church and Greenwich streets will have reached their full height. A year later, Silverstein's Tower 2, at the northeastern corner of the site, will top out as well.

"By 2012, it'll all be over but the shouting," Shorris said.

Both Silverstein and Shorris said they expect the World Trade Center reconstruction to continue as planned, even with the departure of Gov. Spitzer and his replacement by Lt. Gov. David Paterson.

according to that site, people got killed, and the building should be partially destroyed? That's kind of big.

Rock drilling has already started some days ago, so these ones are indeed fully U/C.
Today they also installed the first steel beams of the memorial. They are placed about 1 yard (maybe 2) away from the slurry wall at the north tower
