2019 Excellence in Concrete Construction Award

"Torre Generali" (CityLife)

During the annual gala for the "Excellence in Concrete Construction Award" held on October 21st in Cincinnati, Ohio (USA), ACI recognized the first place in the “High-Rise Buildings” category to the Generali Tower (Milan, Italy). The nomination was submitted by ACI Italy Chapter and the Associación Científico-Técnica del Hormigón Estructural (Spain).

The ACI Italy Chapter is honored to have supported another successful nomination of the Italian Concrete Constructions in the prestigious international award, after the first place of Palazzo Italia at Milan Expo obtained during the Excellence in Concrete Construction Award 2017. "ACI Italy Chapter is proud to have supported the candidacy and to have seen an Italian project be awarded as winner for the second time in three years" declared Luigi Coppola President of ACI-IC.

The Generali Tower was designed by Zaha Hadid and built in CityLife (Milan), under the structural project of Redesco Progetti s.r.l.. The Generali Tower is 186 m (610 ft) tall with a tubular core resisting vertical, horizontal, and torsional actions. A shape variation of each floor plan, and its rotation around the center, generate the form. The concrete raft foundation has 64 settlement-reducing piles. Casting was completed in 38 hours by using low-heat concrete to comply with the specification of the maximum inner allowable temperature of 70°C (158°F), which was checked with thermocouples. A special ground-floor slab is 500 mm (20 in.) deep, with 900 mm (35 in.) deep drop panel areas, designed to resist the horizontal forces created by local column shifts from vertical to inclined.

The Generali Tower has been awarded in the “High-Rise Buildings” category as demonstration of the Italian deep knowledge in engineering structural design. The award recognizes the audacity and the innovation in the application of design methodologies. The marked torsion around the vertical axis of the structure and the consequent high level of stress and strain in the structural elements were recognized as a great design challenge. The sophisticated structure required the implementation of an advanced design methodology which gained the recognition of a such prestigious international institution.

"This award celebrates Italian engineering and the ability to design buildings that have no equal worldwide, from the architectural and technological point of view" - said Eng. Marco Beccati, Technical Director of CityLife S.p.A. - "The Generali Tower was a real challenge and we tackled it thanks to our consolidated know-how that led to the construction of a building that represents the best practice for all similar future projects".
