Basic Introduction


CCTV new site CCTV headquarters building


China Central Television headquarters building


Located in the East Third Ring Road (formerly "Northern Auto site"), Chaoyang District, Beijing, close to the East Third Ring Road, it is located in the CBD core area, covering 197,000 square meters.


The total construction area of about 550,000 square meters, the tallest building 234 meters, project installation with a total investment of about 50 billion yuan.


Construction includes: the main building (CCTV), Television Cultural Center (TVCC), service building and Media Park. After the completion of the project, CCTV will have the ability to broadcast 200 channels of programming.


The building by world-renowned architect, the Dutch architect Rem Koolhaas as master, responsible for the design of the Netherlands Office for Metropolitan Architecture. CCTV new site will be built in five-star hotels, CCTV building consists of two functions, namely, the five-star hotels and Television Cultural Center.


The hotel is set in the CCTV main building. Four five-story building of the hotel lobby and offers restaurants, shops, swimming pools and other public places. Lobby north and south sides of the upper portion 300 rooms surround a central atrium, at the top of the main building of the hotel's Restaurant.


Architectural Overview


Strange shapes


Bidirectional two towers within the main building of the CCTV headquarters building tilted 6 degrees, 163 meters from the "L" shaped cantilever structure as a single entity, the outer surface of the glass curtain wall construction by the strong irregular geometric patterns, unique shape, structure new, large high-tech content, "high, hard, fine, sharp," the large projects at home and abroad belong.


Build complex


CCTV new building is called "pretty hard to build" a start in October 21, 2004. In addition to "front side S O" peculiar shape, the new building of CCTV security has been cause for concern.


Many experts still believe that the domestic building design is too complex, the whole building huge congenital overturning force, destructive impact poor. In this connection, Shary details the security considerations of the building design.


Overall framework


According to Designer, the structure of the CCTV building is composed of many irregular diamond fishing net consisting of metal scaffolding. These diamond scaffolding composed of seemingly different sizes, there is no law, but actually precise calculation. As the main structure of the building, these steel mesh building most exposed to the outside, not as deep as most of the buildings where.


Ole Scheeren said that such pressure can be passed on down the basic system, and find the best way to import the ground. From the exterior, the building part of the steel mesh structure (including pressure and other large parts of the corner) more intensive, they are also part of the overall design ideas.


Due to the irregular design of the building caused by the force of each body part of the building they are very different, these diamond-shaped pieces became regulated by the force of the tool. The site by force, would constitute a much more textured with small diamond exploded force; the force of a small part of it is just the opposite, with less texture constituting the large diamond.


Tower connection


Tower linking moiety draws bridge construction technology, the difference is that if that part as a "bridge", it is a surprisingly large, very heavy bridge. Some parts of this bridge have a full 11-storey, the bridge further comprises a length extending 75 meters cantilever tip without any support.


Beijing construction industry to build this design is not readily available specification, so the structure of the Beijing municipal government organized 13 experts to set up a special group. After two years of design competition, the new CCTV headquarters building approved construction.


Next, the group made a three-story replica used to study. It is placed on a hydraulic platform to simulate earthquakes, installed above the hundreds of sensors for monitoring displacement "tower" on over 10,000 steel beams, and measure in different situations which part of the maximum pressure.


Peripheral Design


CCTV new building outside the large glass windows combined with diamond steel mesh is made outside of the building is made of special glass, its surface made of burnt gray enamel, can more effectively shield the sun, the air quality to adapt to the environment of Beijing. In fact, air pollution is very serious day, such as a glass-like melt in the air, one can only see the network structure of the building, as if lightning is solidified in the air.

Experts


The main building and equipment in good condition


To ensure safe demolition, Beijing Urban Construction Group and experts, owners, design, supervision of common complex CCTV headquarters building


China Central Television headquarters building


Construction program was repeatedly demonstrated, repeatedly refined perfect, and the experimental disassembly, provides the basis for large-scale demolition.


After much scientific proof that the Group of Experts, the main building and the cultural center project equipment inside is intact, the fire were not affected. Hanging curtain wall metal grid as a whole largely intact, reinforced concrete structure is not damaged, carrying roof truss has no obvious deformation, but the individual parts in need of repair. The start of the CCTV Television Cultural Center construction work, demolition and clean-up will be divided into two phases rehabilitation start, all the excesses of the body peripheral floor places need to be demolished.


Construction difficulties


Removing the floor to avoid the influence of body


Metal grid facade and disassembly will be to clean up the entire demolition project construction phase the most difficult and critical node. The personnel, in order to avoid influence of the main structure demolition work building body building, the entire demolition process will use the diamond saw and other leading high-tech and environmentally friendly means, without causing any damage to the building body. After the demolition is complete, CCTV television cultural center project will be re-decorated facades, rehabilitation, but will keep the original design.


Salvage


The construction waste classification


Beijing Urban Construction Group introduced CCTV cultural center project construction area of 103,648 square meters, the building eaves height 159.68 m. Works from the main building and the composition of the podium, the main building of the hotel, from the podium studio, theater, digital cinema, exhibition hall and other functional areas. Currently, the construction side has already done the preparatory work related to demolition work. It is understood that after the removal of construction waste will once again be classified treatment, waste recycling.


Beijing Urban Construction Group introduced, in order to ensure green construction, Beijing Urban Construction Group CCTV EPC Ministry has also developed a construction site environmental protection regulations, to ensure the construction in line with environmental requirements. In the teardown phase, the Beijing Urban Construction Group will dismantle and rehabilitation and construction technology convergence as a key link in advance to develop a project to retain part of the protective measures to lay a good foundation for the rehabilitation and construction.
