Localization of Istanbul in Turkey

Küçük Çamlıca TV Tower ( Turkish Küçük Çamlıca TV-Radyo Kulesi ) is the new TV tower in the Turkish city of Istanbul that has been under construction since 2016 . Since the topping-out ceremony in April 2018, the tower has reached its final height of 365.5 meters and, when completed, will be the tallest structure in the city and the country. It would also make it one of the tallest television towers in the world . Completion is expected at the end of 2019. The tower stands on the 218-meter-high Küçük-Çamlıca hill in the Asian part of the Turkish metropolis and, in addition to its function as a lookout tower, is intended to act as a transmitter for digital television and radio as well as a transmitter station for mobile networks and other services.

history

planning

The proposal for the current construction of the new television tower goes back to the 2000s. The purpose of the construction project is to concentrate the numerous transmitter masts on the Çamlıca hill ridge in one tower and to dissolve the strong visual impairment caused by the dismantling of these steel lattice towers. The mayor at the time, Nurettin Sözen, supported the first draft of a television tower measuring 174 meters. Despite multiple tenders, no company could be found that could carry out the project. Also, Recep Tayyip Erdogan , who was Nurettin Sözens successor as mayor of Istanbul tried to revive the failed project in his time as prime minister. Under the then mayor Kadir Topbaş , the project was finally taken up again. For this reason, on December 10, 2009, the city administration of Istanbul and the Ministry of Transport signed a declaration of intent to unite the radio and television stations in a single tower for the terrestrial digital stations. With the approval of the metropolitan government, the resolution came into force on March 19, 2010. The architecture competition ended on September 5, 2011 . By resolution of the Istanbul Metropolitan Region Council, the construction project was moved from the originally planned Büyük-Çamlıca Hill to the neighboring and smaller Küçük-Çamlıca Hill.

The original height of the television tower was estimated by the architects to be 340 meters. A design that ultimately took second place in the competition provided for the tower to grow up along four mighty pillars, which would be stabilized in four areas via cross-links and should have a curved outer shape with a net-like structure.

With the completion of the new television tower, a total of more than 20 transmission systems in the entire city area would be superfluous. Despite these considerable savings, the new tower cannot cover all of the metropolis’s transmission technology needs. For this reason, it is planned to build two more television towers in a further project phase. No decision has yet been made on the type of design. The project for the new television tower is related to more than 50 planned, already under construction or recently completed major projects in Istanbul, which are or were in the implementation in the 2000s and 2010s. A prominent major construction project was the new construction of Istanbul Airport .

construction

Construction progress February 2017

Construction of the Küçük Çamlıca television tower began on March 1, 2016. The construction company was Sarıdağlar İnşaat. The Balkar Civil Engineering office provided engineering support for the construction.

The foundation depth of the tower is around 20 meters. The concrete used has the strength class C60, the reinforced steel the quality S420, for the structural steel the quality S355JR was used. In April 2018, the top of the antenna support was put on, and the tower thus reached its final height. In a final construction phase, the bulge around the lower part of the shaft will be realized.

description

Structure and foundation

The television tower is structurally divided into the three main areas of a reinforced reinforced concrete shaft , a transition area that partially encloses this tower shaft and contains the tower cage , and from 220.5 meters a steel antenna carrier weighing 1400 tons.

The tower is built on a ring foundation 2.90 meters thick and 60.80 meters in diameter. The four underground floors protrude up to 18 meters into the ground; the entire structure protrudes up to 22.30 meters into the ground. In a longitudinal section, the underground construction forms a trapezoid that expands towards the ground . Mainly technical systems of the building are housed there.

Tower shaft and cage

Construction progress April 2019

In addition to a library, exhibition rooms are to be accommodated in the entrance hall at the base of the tower. There are three elevators in the tower that carry staff and visitors. Two of these elevators are panoramic elevators, they run on the outside of the shaft. In addition to the four underground floors, the shaft is divided into 49 above-ground floor areas, each with a ceiling height of almost 4.50 meters.

The tower shaft, which forms the core of the construction, is surrounded by an asymmetrical metallic-looking shell, which gives the tower an amorphous- organic shape, which results in elliptical- curved curves in different sectional views. In the lower part of the tower shaft, this is still slightly curved outwards, while the shape is more curved towards the tower cage and ends below the base of the antenna carrier. The bulges of the lower shaft area between 60 and 87 meters accommodate antenna platforms, among other things for directional antennas .

The tower cage houses thirteen floors, which are between 145 meters and 196.5 meters high. Two viewing platforms at heights of 148 and 153 meters (33rd and 34th floor) are open to the public. A café will be located on the upper platform and a tower restaurant on the 40th floor at 185.5 meters . Above the tower cage, also visually hidden in the outer shell, there are three antenna platforms that continue above the antenna carrier.

Send function

The main purpose of the new television tower is to replace the many transmission masts on the two Çamlıca hills and thus counteract the deterioration of the landscape. For this reason the tower has a capacity for up to 125 transmitters. On the neighboring Büyük Çamlıca Tepesi there are numerous transmitter masts as well as the 166 meter high Çamlıca television tower , which was built between 1972 and 1976 and is about two kilometers north of the new television tower. The old antenna masts and transmission towers are expected to be dismantled in 2020.

In the European part of the city is the Endem TV tower , which a helicopter hit on March 10, 2017 in thick fog. The tower is no longer used for signal transmission.
