San Francisco's Millennium Tower is still lowering and tilting. But there is now some good news for residents of 301 Mission Street, which has sunk 18 inches and tilted 14 degrees since it was built in 2008. The building's owner, Millennium Partners, has agreed to cut the height of its other three towers by one floor each.
Millennium Tower is not the only building to fall into disrepair over the years. Other famous leaning buildings include New York's Chrysler Building, Chicago's John Hancock Center, and London's Millbank Tower.
The list of fallen skyscrapers is long and includes some very notable buildings. The destruction that can be caused by a collapsed tower is enormous; warnings about the dangers of climbing these structures exist on many websites.
It is important to understand that all tall buildings are at risk of collapsing due to natural disasters, arson, or neglect. The key factor in determining if a building will collapse is its construction quality. If an older building suffers major damage such as this, then it could collapse without warning.
Many factors can cause a building to lean, including inadequate design or construction. For example, if a foundation is not deep enough, then the building will tend to settle over time. This movement may be small, but over time, it can cause a tower to lean toward one side.
The Capitol Gate Tower With an 18-degree slope, Abu Dhabi's new Capital Gate tower is the world's most slanted edifice. It easily beats the previous Guinness World Record holder, a medieval church tower in Suurhusen, Germany, with a 5.19deg slant.
The tower will serve as a gatehouse for The Capital Gate development, which is being constructed on the western edge of the capital city of Abu Dhabi, United Arab Emirates. The $350 million project will feature a hotel, offices, and apartments. Its developer, Emaar Properties, said the building was designed to reflect Abu Dhabi's unique climate and location, with its skyline dominated by dry forests of date palms and acacia trees.
The tower's steepness allows for more efficient use of land, as well as reducing energy costs due to its design with thermal massing. It is also considered a landmark building, since it resembles a piece of jewelry: a slender thread connecting two monumental structures - a circular base supporting the tower above it. The tower's shape was chosen as an attempt to overcome Abu Dhabi's lack of natural resources. The country has only 12 million barrels of oil reserves but needs ways to attract investment while maintaining a good quality of life for its people.
Abu Dhabi is one of the seven emirates that make up the United Arab Emirates. It is located on the northeast coast of Saudi Arabia across from Oman.
In New York City, Steinway Tower, 111 West 57th Street, also known as Steinway Tower, is approaching completion. It is the world's skinniest skyscraper as measured by its height-to-width ratio. The 1,428-foot skyscraper is 24 times as tall as it is broad, and each floor contains only one dwelling. The apartment is believed to be owned by the musician Billy Joel.
Steinway was designed by Grosvenor Charles Harrison & Associates and built by Pulte Housing Corporation. It will have 420 apartments when it opens in 2009, with prices starting at $1 million for a 652-square-foot studio apartment. There are no common areas or parking facilities on any of the 27 floors. The building's name comes from the former tenant, the Steinway & Sons piano company. No word on whether the pianos in the apartments will be free.
When it opens, Steinway Tower will become the first skyscraper in New York City to be under 10 stories wide. The previous record holder, the World Trade Center, was 9 1/2 stories wide.
The previous record holder for the tallest building in New York City was 740 feet, set by Lever House at 110 South Park Avenue in Midtown Manhattan.
(Source: CBS News) Although it is not evident to the naked eye, the Leaning Tower of Pisa is not leaning as much these days. In fact, it's roughly an inch straighter than it's been for generations. The transformation took 12 years and was the outcome of a massive renovation operation.
The Leaning Tower of Piazza dei Miracoli is the iconic landmark of Pisa and one of the most recognizable structures in all of Italy. Built between 1173 and 1250, it is a famous example of Italian Gothic architecture. The name "Leaning Tower" is somewhat of a misnomer, since it is actually "On its Side" rather than leaning (although it does lean slightly towards the west). The reason for this is because the original builder, Gherardo da Linaje, was not able to pay for the finishing touches of the structure and had to sell part of his future income to cover his debt. He did not have enough money to properly cement the foundation, which caused the building to slowly sink over time.
In 2009, after several attempts, a group of engineers determined that the best way to bring the structure back into line with reality would be to cut away at the base of the tower until it was level again. The operation was completed in April of 2018.
