New York, N.Y. — Thornton Tomasetti Inc. and Hardesty & Hanover LLP have formed a strategic alliance to collaborate on the evaluation and engineering of transportation infrastructure and movable structures.

The alliance unites Thornton Tomasetti’s global reach in the design and evaluation of stadiums, arenas and special structures, and Hardesty & Hanover’s expertise in the transportation sector as well as architectural kinetics.

Both firms have extensive experience in the transportation and sport markets. Hardesty & Hanover has worked on bridges and other moveable structures nationally and internationally. Thornton Tomasetti has designed or evaluated more than 35 major sports facilities, and conducted a forensic investigation of the August 2007 collapse of the I-35W Bridge in Minneapolis. It maintains 18 offices, including six outside North America.

"Through our combined offerings, we are able to address the investigation or design of a wide range of structures and their mechanical and power systems," said Tom Scarangello, chairman of Thornton Tomasetti. "This is a natural progression of our more than two decades of working together, and we see great potential by formalizing our collaboration, especially in the transportation sector and for movable structures."

Paul Skelton, partner of Hardesty & Hanover added: “We are excited we have harnessed the capabilities of two world renowned engineering firms — Thornton Tomasetti’s expertise with new and existing structures combined with Hardesty & Hanover’s prowess in transportation infrastructure and architectural kinetics,” he said. “We can now formally offer this blend to the planners and owners of tomorrow’s momentous structures.” The alliance formalizes a decades-long relationship between the two firms, marked by collaboration on a number of projects.

The two firms collaborated on the replacement all of the drive system for the five retractable roof panels at Miller Park, home of the Milwaukee Brewers baseball team. They also worked together to determine the cause of premature wheel bearing failures for the retractable roof drive system of another stadium and on a multidisciplinary evaluation of the 34-year-old Roosevelt Island Aerial Tramway system in New York City.
