@ ZZ-II

I think no because they have taken out the crane in the hole and possible the excavator too as you can see in the picture below. It seems we are going to get a lots of progress soon.

The bloke has a right to ask a legitimate question.

The only three steel frame buildings ever to collapse from fire were all in America, all in the same city and all on the same day. And one wasn't even hit by a plane.

He has a right to be concerned since it seems steel framed buildings act differently in the USA to steel framed buildings in Madrid or China.

They act differently? mmmm, maybe in the USA they use cheap steal, to save money, or maybe because they like their buildings to fall...

...or wait, maybe we can't say they act differently becasue:

- There are no buildings in Europe (let alone Spain) as big as the Twin Towers, and no skyscrapers at all that have the same structure at all.

- In China there are no buildings with a structure like the Twins had that are half the size of the Twin Towers.

- Nor in China nor in Spain, a building was hit by a Boeing 757 with the tank full of extremely flammable fuel .

-China and Spain don't have one single building that tall that was built over 40 years ago (construction started in 1966). And wait, now that I think about it, neather does the rest of the world... (security issues have obviously changed in almost half a century, let alone building technologies and materials).

-As for the third tower, a few comparisons can still be made: no other building was ever hit by a flying fireball formed by a motor of a 757 that came from more that a 150 meter height and from an airplane that was flying at 537 mph ( 864 km/h).

It would be smart and appropriate to do some research before talking nonsense (you can use internet also for this, and not only for skyscrapers and porn)

I have a ton other examples if you want, but I think to continue would be unnecessary and stupid . Just like your comment.

The Twins collapsed because of a failure of there main selling point, more floor space with less columns in the middle of the floor. The Floor trust held the exterior support and interior port together, keeping the tower standing. The floor trust burned out, broke loose from the exterior wall, with those gone, there was nothing connecting the Exterior wall (which partly held the building up) with the elevator core. (understand that? I worded it the best i could)

Buildings in America are not made the same now, they are made from in forced concrete and steel, more column supports and better safety protocols. Also, that fire was caused by jet fuel. Its really the first time an airplane has been flown into a tower, so we dont know how Chinese metal would stand up or even European metal.

Now, back to the spire.

To fully understand the nature of the Twins collapse go here:http://wtc.nist.gov/

To get a handle on the myths and misconceptions, not to mention the retarded conspiracy theories, go here: http://wtc7lies.googlepages.com/home


Now on topic. They have finished the core caissons and it seems they've already been excavated. When can we expect to see some rebar and formwork for the core concrete slab to start going down into the hole?

Also does anyone know just how many of the caissons for the garage have been completed?

May 21 - AM 2

Large grinder ( makes sockets in the dolomite limestone for the "rock caissons" )

April 2 2007


May 21





Long drill shaft - with air connection on top ( when in the core they used a device that allowed the air to be connected in the middle of the shaft ( 2 shafts joined ).



Secant beams ( columns ) fewer every time I visit.


Is this 2 sets of sleeves and 1 pair of tops ?


Note that they are preparing to make longer rebar cages.


Morning stroll


More of the view

Is this building EVER going to get out of the ground??

I suspect the world is starting to have doubts. Does anyone reading this have any insight? Please share.

Also wanted to mention I'm just spent a weekend in San Diego where my friend owns a condo near PetCo Park. Within a few blocks of his building there must be 5 - 7 completed 40+ story towers with almost no tenants.

Hi

Keep following this project from here in the UK. Have to say would like to see progress but I will wait patiently. One thing when it is built it will be one hell of a view. Didnt realise until these latest pics how close it is to open water, saw it next to the river but had never seen what was on the other side of the bridge.

Why would the world have doubt? It is not like they haven't been out there working every day. These things take long. It is a 2000' tower being built. The foundation is going to take some time. Maybe if we had thousands of people working at slave wages like other 2000' towers in the world it would go faster. The fact is we don't.

As for the buildings being empty in SoCal, well the market there sucks. That is why they are empty.

They've been working on the foundation for nearly a year, right?
It seems like that is a pretty long time, regardless of height.

The City of Chicago has granted Case the permit and construction will commence within weeks.

"This marks a significant milestone, as it was the last step before officially beginning construction on The Chicago Spire" said Garrett Kelleher, executive chairman of Shelbourne Development Ltd. & the Shelbourne Development Group, Inc. "We're very proud to add Case to our outstanding global development team."

Case will provide 34 concrete and steel caissons that will comprise the foundation of The Chicago Spire. The caissons will be drilled 120-feet deep into the bedrock to support the 150-story building’s structure. In addition, Case will excavate a 104-foot diameter cofferdam 78-feet deep to create a dry work environment. The cofferdam will serve as the foundation for the core of the building.

Construction of this underground phase is expected to be finished in the first quarter of 2008. Environmental remediation is complete on The Chicago Spire site and Shelbourne’s environmental consultants STS have completed gathering field samples at DuSable Park. The Chicago Spire site has been cleared, secured and is ready for caisson construction. The Spire is scheduled for completion in late 2010.

The sales effort will launch in September 2007 with a global marketing campaign. The Chicago sales center will be located in the 18th floor of the NBC Tower, 454 N. Columbus Drive, which overlooks The Chicago Spire site. United Kingdom-based Savills Plc., a leading international property advisor with experience marketing some of the finest residences around the globe, will lead the sales campaign.

For more information about The Chicago Spire and Shelbourne Development Group, Inc., see http://www.shelbournedevelopment.com/ and http://www.thechicagospire.com.
Seems like they're already behind schedule.
