Iberdrola Tower by Cesar Pelli

Iberdrola Tower will be the tallest building in Bilbao (Basque Country, Spain).

The famous architect Cesar Pelli, also made Petronas Twin Towers in Kuala Lumpur.

Iberdrola Tower will have 41 floors and it will be 165 meters tall.

Construction Started in 2007 and it will be finish in 2011.


The property is Iberdrola and the constructors are Afer Group.

In the photos we can see the construction process in this phase:

The reinforced concrete structure, like in other skyscrapers, it is made by a concrete core where there will be the lifts and which also helps on the stability of the structure.

The concrete floors are made with a climbing or sliding formwork (example of an sliding formwork), which is sustained in the central core. In the Iberdrola Tower case they make 1 floor on 1 week and it slides up to continue building.

In most skyscraper the facade starts when the structure is not finished, because if not, the construction will delay a lot of time. Here we can see how the facade have been started and the structure haven´t been finished. In the photos we can see the sustentation of the facade glass to the slab.

If you have any cuestion of the construction, you can ask on my blog or in my personal email. I´m not participating in this building construction but if i can, I will help on your doubts.



Español

La Torre Iberdrola con sus 165 metros y 41 plantas, será el edificio más alto de Bilbao (Superando a la Torre BBVA de 97 metros) y de toda la Comunidad Autónoma Vasca.

Su famoso Arquitecto es César Pelli el cual tiene una gran experiencia en la construcción de rascacielos como por ejemplo las Torres Petronas de 452 metros en Kuala Lumpur.

La construcción comenzó en 2007 y esta prevista su finalización en 2011.

El promotor es Iberdrola, y la constructora el Grupo Afer.

En las fotos se puede apreciar el proceso de construcción en esta fase de la obra:

La estructura de hormigón armado, como en la mayoría de los rascacielos, esta realizada mediante un núcleo central que le da estabilidad a la estructura y en el cual se alojarán los futuros ascensores, un total de 21 en la Torre Iberdrola.

Para realizar la estructura del rascacielos se utiliza un encofrado trepante (ejemplo de encofrado trepante), el cual se sostiene en el núcleo central, y conforme se realizan los forjados y los muros del núcleo trepa hacia arriba para continuar con la siguiente planta. En el caso de la Torre Iberdrola se realiza una planta por semana.

Respecto a la fachada, como en la mayoría de los rascacielos, ésta comienza mientras se está realizando la estructura, ya que si no la obra tendría una duración mucho mayor. En estas fotos podemos ver como se ha empezado a colocar la fachada en una de las plantas y tambien se puede apreciar el sistema de anclaje de los paneles de vidrio a los forjados.

Si tenéis alguna pregunta sobre la construcción, o si participáis en la construcción de la Torre podéis hacer un comentario en el blog o escribirme a mi email personal. Yo no estoy participando en la construcción de este edificio, pero puede que alguna de las dudas sobre el proceso de construcción pueda resolveros.

También os recomiendo el blog:
Ya que suele adelantarnos siempre las noticias sobre las construcciones en el Gran Bilbao y entre ellas nos habla cómo no, de la Torre Iberdrola (web oficial).

HSB Turning Torso

HSB Turning Torso is the tallest building in Scandinavia, having 54 floors and being 190 metres tall (623 feet). It´s located in the city of Malmö in Sweden.

It´s the first skyscraper made by the spanish world renowned architect and engineer,
Santiago Calatrava. The design is based on a white marble sculpture by Calatrava called Twisting Torso which represents a twisting human being. When Johnny Örbäck, former CEO of the Turning Torso contractor and Board Chairman of the Malmö branch of the co-operative housing association HSB, saw the sculpture in 1999, he contacted Calatrava to ask him to design a building using the same concept.

The skyscraper has got 147 luxury apartments and office spaces.

Its construction started in the summer of 2001 by Swedish
NCC constructors and it was inagurated on the 27th April 2005.

In the next video we can see how the workers built floor number 36 in just one week.

Kansai International Airport

Kansai International Airport is located on two artificial islands in the middle of Osaka Bay in Japan. It´s the first airport located on an man-made island.


The construction:

In 1987 the construction began.
In 1989 the sea wall of the first Island was completed.
In 1990 the 3km long bridge was finished.
Between 1991 and 1994 the Terminal was built. It was designed by the world renowned Italian architect Renzo Piano, the same architect who designed the Centre Georges Pompidou in Paris.

On the 19th April 2001, the airport was one of then ten structures which were given the "Civil Engineering Monument of the Millennium" award by the American Society of Civil Engineers.

In the next video we can learn a lot of aspects concerning the building of the Kansai International Airport, like how to resolve the gradual sinking of the island, as well as the advantages and disadvantages of locating an airport in the middle of the sea.

Taipei 101

Taipei 101 as its name says is in Taipei in the Republic of China (also known as Taiwan) and has 101 floors above ground and 5 underground floors. The Taipei 101 was the tallest skyskraper in the world, until the 21th July 2007 when the Burj Dubai overtook that title. It was designed by C.Y. Lee & Partners.

The construction started in 1998 and it was opened to the public on the 31st December 2008.


A engineering interesting aspect:


Taipei 101 has a tuned mass damper (also kown as active mass damper AMD or armonic absorber) of 660 metric tons suspended from floor 92 to floor 88. The particularity of this AMD is that anyone can see it, because it´s shown to the people. This AMD was designed by Thornton-Tomasetti Inc and Evergreen Consulting Engineering.


Videos:

Now we can see a video composed of 5 parts, showing the construction of the skyscraper. Then, I have put another video showing us the tunned mass dumper in action and finally 2 videos about the wind that hits the top of the Taipei 101.

I hope you´ll enjoy it.

Daruma-otoshi demolition technology

The Daruma-otoshi demolition system was invented by the Japanese construction company, Kajima Corporation.

This technology to demolish skyscrapers consists in replacing the support columns with gigant computer controlled hydraulic jacks. Then, the first floor is demolished and the debris is taken out. Next, the entire building is lowered down with the hydraulic jacks and the demolition of the second floor begins...till the end when the last floor is demolished.

The method is called daruma-otoshi, because of an old Japanese game called that way. It consists of hitting a Daruma doll (composed of 5 pieces one on top of each other) using a small hummer, from bottom to top, avoiding the pieces from falling during the whole game. The Daruma-otoshi japanese video game is available here.


Video: Daruma-otoshi demolition method used in floors 17 and 20 of buildings in Tokyo, Japan.



Advantages:
- City center buildings can be demolished without interrupting the traffic.
- Too much space is not needed to collect debris, because it is taken out all the time.
- The recycling process is more effective: 99% of steel and concrete and 92% of the interior materials.
- No need for explosives.
- The demolition is better controlled and safer.
- Less noise is produced.
- It's 20% faster.

Disadvantages:
- I suppose that it must be more expensive.

Citigroup Center in New York

The Citigroup Center (First called Citicorp Center) is in New York City. There´s also another Citigroup Center in Chicago, but I´m going to speak about the skyscraper of New York. It is 278.9m (915 foot) tall, with 59 floors. It is easily distinguised in the skyline of NY because of his 45º angled top base, which was thought to have luxury apartments on it and then, solar panels, but finally they didn´t do anything.

The skyscraper, completed in 1977, was designed by the american architect Hugh Stubbins Jr. for Citibank. The engineers were William LeMessurier and Associates.

This building was pioneer in using a shock absorber, technically called tuned mass damper (TMD). They were used in bridges but not in buildings. Nowadays the tuned mass dampers are used in skyscraper architecture to reduce movements of the building in windy days or when earthquakes happen. The Citigroup Centers TMD is a 400 tonne concrete block moved by a hydraulic system.

In these 2 videos we can learn how engineers resolved structural problems before the design and once the skyscraper was built.
