The peculiarities in the layout and concentration of the reinforced concrete, with 330 tonnes of steel distributed in a 592 m2 area and a volume of 1,200 m3, make the concreting a particularly complicated task.

It took 16 hours, 2 concrete plants, 25 cement mixers and 2 x 43-metre pumps to achieve a discharge flow of 75 m3/hour of concrete, reaching 100 m3/hour at the peak of the operation. A careful strategic plan was instrumental to ensure the team in charge of this first phase could achieve a truly satisfactory result in a shorter time frame and under considerably adverse conditions.

The project comprises 2 main parts: the two technical blocks at two different heights, and the central part of the tower formed by two separate rectangular nuclei with a total height of 47.20 metres and joined at the top part of the technical blocks and the control room.

In the final section of the two nuclei, between the height of 27.72 m to 37.62 m, there are three integrated rectangular floors that protrude 3.80 metres to the exterior at both sides of the tower and which incorporate three higher floors that remain suspended in mid-air, reinforced by the steel cross on the façade.
