Tom joined Thornton Tomasetti in 2012 and was previously a principal associate with strategic partner Hardesty & Hanover. His breadth of experience enhances the firm’s client offerings in three key areas: bridge and transportation forensics; kinetic structure design, especially movable roofs for stadiums; and business development across the Forensics and Renewal practices.
A History of Partnership
Tom’s relationship with Thornton Tomasetti goes back more than a decade, and includes collaboration with individuals in many offices. While at Hardesty & Hanover, he was involved in a number of the firm’s structural evaluation and forensic projects, such as the movable roof bearing replacement project at Miller Park in Milwaukee, Safeco Field in Seattle and the rehabilitation of the Roosevelt Island Tramway in New York City.
Tom’s bridge credits span nearly a dozen states, from the Verrazano Narrows and George Washington bridges in New York to the Carlton Lift Bridge in Bath, Maine, and the Third and Fourth St. bridges in San Francisco. He has also worked on many bridges outside of North America, including in Waterford, Ireland; Northern Ireland; and Manchester, UK. His professional credits include eight retractable roof structures, an expertise that dovetails well with the firm’s stadium and arena work.
He sits on the advisory board of the Urban Assembly School of Design and Construction in New York City and has been a mentor and technical advisor for Smith College’s Picker Engineering Program.
