The Trump International Hotel and Tower, also briefly Trump Tower, is a 98 - story skyscraper in the Chicago American, which was completed in 2009. He has since become the second tallest building in Chicago and currently the third highest in the United States. The building is owned by the well-known real estate developer Donald Trump and was designed by the American firm Skidmore Owings and Merrill.


Planning and construction

The construction of the building began in May 2005, after the project has already been presented to the public in 2001. At that time, announced a project developer Donald Trump to build the tallest building in the world in Chicago. After the terrorist attacks on September 11, 2001 in New York this plan was rejected due to security concerns. Instead, the height of the building was reduced to about 327 meters. Shortly before the start of construction has been published that the building including the spire should be about 415 meters high. From the year 2006, the foundation works were completed and the concrete structure of the tower began to grow into the air. At the construction site several tower cranes were active, which could climb with the help of a hydraulic system with the increasing height itself up. The installation of the glass panels began in the spring of 2007. In September 2008, the site reached the height of the roof. In January 2009, the tip was mounted in several parts while interior work and work still ongoing at the glass facade to May 2009, by helicopter. Alone, the plot has cost about 70 million U.S. dollars. The entire expenditure totals increased to 750 million dollars.

Architecture and Design

With this position, located right on the Chicago River near the North Side, is the building in the Chicago skyline between the Aon Center and the John Hancock Center at the mouth of the Chicago River from Lake Michigan to find (View from the Navy Pier to the skyline ). The building is fully glazed and thus clearly stands out from the surrounding buildings in the area directly from. The tower has 98 floors and houses 625 apartments with 220 hotel units.

The skyscraper is a total of 423 meters ( 357 meters to roof, the peak counts for height ) and making it the third tallest building in the United States and in Chicago. Within the U.S., the building will be surpassed by the 541 -meter-high One World Trade Center in New York, and after it is ranked by the 442 -meter-high Willis Tower on the second place of the tallest buildings in Chicago. Although the Trump Tower is the second tallest building in the city and the third highest in the country, he is in Chicago surpassed by the antenna masts of the John Hancock Center ( 457 meters). This height measurement is not used for architecture and thus the official building height, but only used when collective term structure.

The building narrows towards the top with several recesses on different sides. The recesses of the building located at heights of 60 meters, 130 meters and 200 meters. The recovered by the recesses outdoor space is as open spaces for hotel guests and residents. There are also smaller parks and seating were built. A little below the roof is another smaller return. The roof itself is located in 357 meters height above the 98th floor. On the roof of a 66 meter long tip was installed. This is often bathed in colored light at night.

Change in elevation

By November 2009, the height of the tower at 415 meters was specified instead of 423 meters. The Council on Tall Buildings and Urban Habitat, the internationally recognized Commission for height issues with skyscrapers, but decided on 17 November 2009 that the building does not have to be measured from the front door up to the top, but from the building entrance on the Chicago River side. Thus, a difference in height of eight meters comes to pass. Within Chicago, the building remains true to the rank of the second highest skyscraper after the Willis Tower, exceeds in the world list, but since then the Jin Mao Tower (421 meters to tip ) in Shanghai.

Method of construction

The building was built entirely of reinforced concrete. At present ( 2014) is the Trump Tower to become the tallest reinforced concrete building in the world and triggered in the 390 -meter high CITIC Plaza in Guangzhou, China, from. Although the Burj Khalifa in Dubai, up to a height of over 600 meters built the tallest building in the world at 828 meters in reinforced concrete construction, but also follows a steel frame construction. Therefore, the Burj Khalifa is considered one of the buildings with mixed support structure, even if the concrete structure of the Burj Khalifa is significantly higher than the Trump Tower.
