Chicago Spire @ foundation

Chicago's buildings are known for innovative and revolutionary designs. The Chicago Spire will complement this pattern, and standing at 2,000 feet (610 m), will further transform the already changing Chicago skyline. Crane parts and construction equipment arrived at the site on June 25, 2007. The following day Shelbourne Development officially announced the first construction contract.

Plans for the tower include 1,193 condominiums with each of the building's 150 stories rotating exactly 2.44 degrees from the one below for a total 360 degree rotation. For supplemental structural support, each floor would be surrounded by cantilevered corners and four concave sides. Similar to the Sears Tower and John Hancock Center skydecks, the Chicago Spire will house a community room at the top floor offering residents a view of four states. The soaring four story lobby of the skyscraper will have translucent glass walls and be framed by arching, steel reinforced concrete vaults. The building has been labeled as a giant "drill bit" by the public and others in the media have likened it to a "tall twisting tree" and a "blade of grass".

Cool. It's one of the most great man made structure I've ever seen from surfing online. Earth moving equipments really great for developing nations. Heavy equipment like altec bucket trucks are reasons of awesome structures.

I am amazed with the architecture of this building. The one who suggested this is brilliant. It really looks like a big drill or screw soaring towards heaven. I wonder how the glass will be maintained since its spiral.

Wow! That is some building. It looks like it’s going on an upward spiral, but if you look at the windows, it’s not. That is indeed state of the art, if ever I saw any, and architecture IS a branch of art. Santiago Calatrava really did a great job in coming up with the design concept for the Chicago Spire.
