Crystal Tower is the second tallest building in Spain, behind Torre Caja Madrid. At an altitude of 249 meters in 52 floors. Construction began in 2004 and was completed on December 4, 2009. The facades are covered with glass and only the top level, the variation of the plant generates changes in the four planes of the facade that gives the building the appearance of cut glass. The building is located in the Madrid district of Fuencarral-El Pardo, the skyscraper complex Cuatro Torres Business Area. The first floor of Crystal Tower is 10 meters high and at the top of the tower is a vertical garden covered winter. The tower was designed by architect Cesar Pelli. The project also included the architects Inigo Ortiz and Enrique Leon. The building is used entirely to office space.

To build the core of the Torre de Cristal, we used three versions of the modular ACS. There were no problems in arranging the ACS console (R = Regular), ACS P (P = platform) and ACS G (G = Gallows) that might work in parallel ensuring optimal work procedures. The set of 1150 m² VARIO wall formwork, including concrete pump, was distributed in ten separate console units. According to the building won in height, the thickness of the core walls was reduced from 120 cm to 70 cm. Special adapters can perform the climbing saving changes in the thickness of the walls.


Torre de Cristal. One of the main attractions of this building is the vertical garden is 250 meters high, with a total area of ​​600 square meters and over 24 000 plants.
In the initial project, the building also had a kind of beacon placed in the top, designed to illuminate the garden and also make the skyscraper visible from many parts of the city. However, the Consistory demurred to the initiative. Apparently, according to sources pointed to the insurance company, the Consistory was afraid that the "lighthouse" tower could interfere with air safety in the capital. Mutua Madrilena understood at the time the observation of the computer hall and decided to remove it from your project.
The structure of the Torre reminded Egyptian obelisks, although in this case, carved on a large block of clear crystal, whose faces capture the light from heaven "like a cut diamond." The variety of angles that define each of the sides gives life and movement to the tower through the different intensity of light that they reflect all day.
