Focus on IIW Ugo Guerrera Prize

Sponsored by the Italian Institute of Welding this IIW Award recognises an individual or team responsible for fabrication of an outstanding recently completed welded construction from the viewpoints of design, materials or fabrication methods. It was awarded in 2019 to Mrs Claudia Pavan and her team from Cimolai (Italy) for the construction of The Oculus. Call for Ugo Guerrera 2022 is being launched, so don’t miss the opportunity.

The Ugo Guerrera Prize 2019 is awarded to Mrs Claudia Pavan (Italy), Project Manager, and her team from Italian steel fabricator Cimolai SpA who were responsible for completing the complex and unique welded structure of The Oculus, World Trade Center Transportation Hub, New York, USA.
Pavan holds a degree in Civil Engineering from the University of Padova and achieved her Master degree in Design of Infrastructures at the University of Padua in 2004. She has worked with Cimolai since her graduation on a range of international construction projects, becoming a Project Manager in 2011.
The Oculus serves as the main entrance hall to the hub which provides intra-city and interstate transit services for more than 250,000 daily commuters, users and visitors. The bird-like design of the building required an extraordinary level of coordination, detailing, assembly and welding expertise. In addition to complex joints and
welding details, the main challenge was to fabricate the elements within a tight tolerance. As most of the elements were three-dimensionally curved plate steel, a detailed study was performed to defi ne the shapes and establish appropriate tolerances. The welding fabrication was completed with the highest level of commitment and quality.
