Construction of the tower was entrusted to some of the world’s most talented private contractors. Over the course of five years, more than 30 Italian and international studies supported both the planning phases and actual construction. The construction site was also an important training ground for 35 recent graduates in engineering and architecture, who participated in two editions of specialist training in high-rise buildings in collaboration with the Turin Polytechnic and local Chamber of Commerce. The Intesa Sanpaolo tower is one of a kind for its architectural innovation and the cutting-edge technologies and materials used, including geothermal power, automated regulation of interior lighting based on natural light and a double-skin facade with panes of glass that can open and close. The main structure of the tower rests on a transfer structure featuring 6 mega-columns, which bear the weight of the 32 upper floors and of the 5 floors that house the suspended auditorium.
