This may not be topped out yet, they still have to install the fiberglass rings around the spire structure. It's possible that the top piece extends beyond the structure, since it looks like it was cut a little short.

Looks great, nice pictures cbotnyse!

What an awesome sight! I'm so jealous of all the folks who got to watch that live. Those construction workers have to be psyched, what a thrill to be a part of all that.

I can't wait to see this building in person.

Trump Tower spire topped out; installation brings tower's peak 90 feet short of Sears Tower



In a sky-high drama that few would have anticipated after the Sept. 11 terrorist attacks chilled America's appetite for building tall, construction workers on Saturday installed the underpinnings for the spire atop Donald Trump's Chicago skyscraper, which ranks as America's second-tallest building after Sears Tower.

Even as biting winds snapped the flags on the Michigan Avenue Bridge, a blue and white Sikorsky S-61 helicopter dangled three-legged steel sections of the spire over the tower's roof. Ironworkers aligned the sections, then bolted them into place, despite the blasts of cold air from the winds and the helicopter's clattering blades.

"That's the amazing thing--that [the ironworkers] have the dexterity to put the bolts in at this temperature," said structural engineer Dane Rankin, who worked on the skyscraper for its architects and engineers, Skidmore, Owings & Merrill of Chicago. "It's going to be a long time before we see another one like this in Chicago."

As the spectacle unfolded more than 1,300 feet above the sidewalk, with the chopper levitating near such landmarks as the Wrigley Building, pedestrians on Michigan Avenue stopped in their tracks and recorded the sight with a variety of devices--cell phone cameras, camcorders and conventional cameras.

Among the astonished onlookers were Eddie Campbell and his wife, Margaret, from Dublin. Standing in the plaza of 401 N. Michigan (the former Equitable Building) and leaning back to take in the sight, Eddie Campbell said, "We're from Ireland. We don't have construction on this scale over there."

The operation took four hours and fifteen minutes, ending just after 1:45 p.m. as a cable from the helicopter was unhooked and the chopper roared eastward over the Chicago River toward Midway Airport. The construction workers had installed eight steel sections atop the five sections that already formed the spire's base.

Four sections were intentionally left bare to prevent the wind from blowing on them like a sail. That would have made it difficult for the ironworkers to align the sections. The fiberglass will have to be installed around the steel trusswork in the coming weeks.

The spire stretches the height of the financially troubled hotel and condominium high-rise to 1,361 feet, 90 feet shorter than Sears Tower and one foot shorter than one of the World Trade Center towers destroyed on 9/11.

Trump, the New York developer and reality TV star, had considered erecting the world's tallest building on the site, but lowered the skyscraper's height after the terrorist attacks. Later, when he expressed disinterest in putting a spire on the tower, Mayor Richard M. Daley ordered him to do so, leading to the Chicago Tribune headline: "Daley to Trump: 'You're spired!'"

On Saturday, however, there were no celebrities or leading politicians in evidence. The stars of the drama were anonymous construction workers.

After the helicopter lowered the fifth section of the spire into place, an iron worker clad in a red jacket climbed to the top of the section and disengaged the cable to which the steel piece had been attached. Seen through binoculars, he resembled a fly. "That's the lead dog pulling the sled," said one onlooker on the construction team.

Beginning in late October, several previous attempts to install the spire were postponed. One, last month, was aborted because of high winds.

Here is a time-lapse of the tower's construction. Here is an in-depth look at the spire's construction technique. The tower is expected to be completed in late spring or early summer.

Sorry! I added the links and bolded the section now, for anyone who missed it, at the very bottom of the article.
