Firm Profile

Guy Nordenson and Associates (GNA) is a structural engineering practice concentrating on collaborative design with architects and clients.  The practice was established in 1997 by Guy Nordenson following 20 years in practice in San Francisco and New York, the last 10 as director of Ove Arup & Partners New York, which he established in 1987. 

The practice focuses on a number of on-going collaborations with architects.  Recently completed projects include the New Museum of Contemporary Art in New York and the Glass Pavilion at the Toledo Museum of Art in Ohio with SANAA and the Nelson-Atkins Museum in Kansas City and the University of Iowa School of Art and Art History with Steven Holl Architects.  GNA was also the structural engineer of the Museum of Modern Art Expansion in New York by Taniguchi and Associates with Severud Associates.  Current projects include the World Trade Center Memorial Museum Slurry Wall Bracing Structure in New York with Davis Brody Bond and the Kimbell Art Museum Expansion in Fort Worth with Renzo Piano Building Workshop.  Beyond museum experience, GNA has established itself as an effective collaborator in the design process of complex and challenging projects, including the World Trade Center Tower One in New York with SOM and the Patent Office Building Courtyard Roof in Washington DC with Henry N Cobb/Pei Cobb Freed & Partners. 

Our practice at GNA is founded on the principle of close collaboration as an essential basis of design.  We have established relationships with architects and clients that extend 10 - 20 years in some cases.  From that foundation we have developed a basis of trust and confidence that has allowed for successful advances in structural designs and technologies to be incorporated in major building projects.  Ours is a progressive approach based on careful analysis of alternate schemes and execution with advice from a wide network of specialist fabricators.
