      Iberdrola tower was created by the architect César Pelli
      Cesar Pelli was born in Argentina the 12th October 1926.
After studying architecture at the Universidad Nacional de Tucumán Pelli completed his studies at the School of      Architecture  at the University of Illinois at Urbana-Champaign. He started his career in the New Haven offices of architect Eero Saarinen.

The colosal structure: its roots have 20 meters Deep.For the execution of the fundation and walls of basements TRIO panel was used.
For the realization of the floors in basements and  modular system for slabs: SKYDECK and MULTIPROP towers ,which overlapping and bracing with racks allowed to reach free heights up to 9.6 metres,always working safely conbined.
The backbone of the building is its core, which accommodates stairwells, installation rooms and 19 lifts. Embedded therein are forged, that decline as we're raising and supporting their perimeter pillars that transmit efforts to the foundation. For the implementation of core autotrepa system (ACS), this gave the customer the possibility of concreting and climbing around the core once or dividing into two phases. In turn, hanging autotrepas, PERI design a bridge crane that allowed the erection of the steel core structure that ran behind the concrete will be made much more flexible way, regardless of the crane-tower work.

For the execution of the slabs the props SKYDECK on MULTIPROP system dismounted, which provides very high yields of execution it was used. Only in the lobby area of ​​the building he alighted on a Rosett shoring of about 7000 cubic meters. The system chosen for the pillars was the SRS, metal mold halves with simple and fast shuttering and stripping mechanisms .



This skyscraper is the replacement of the Provincial Tower. A similar project, intended to bring together in one building all offices to the Provincial Council of Biscay has spread through the city, and it was finally canceled in 2003 due to its high cost.the building took 4 years
