I have been working continuously at the Empire State Building since 2008, and it amazes me. The more you discover about it, the more you appreciate the structural engineering of the past.

Sergio Londono has been a member of the Thornton Tomasetti team since 1999. He has more than 30 years of experience in the review, analysis and design of a wide range of structures, from high-rise commercial and industrial buildings to stadiums and parking structures. His portfolio includes the structural design of Ford Field in Detroit, Michigan, condition evaluation and alteration work at New York’s iconic Empire State Building (which ranks as his all-time favorite project) and site recovery work at the World Trade Center.

Earthquake Engineering Expertise
Sergio has a broad understanding of earthquake engineering. He is a former member of the Commission for the Assessment of Seismic and Volcanic Risk in his native Colombia and conducted seismic risk and hazard studies for several of the country’s major hydroelectric power projects. Sergio studied at the International Institute of Seismology and Earthquake Engineering in Tsukuba, Japan and worked at its Building Research Institute. He has also written and lectured extensively on seismic issues.

Mentoring the Next Generation
Sergio has been actively involved in the ACE Mentor Program since 2002. He has served as a mentor for the Newark, New Jersey Team 2 for 12 consecutive years.

Outside of Work
Sergio is the father of four children. The oldest two followed him into the AEC business. One is an architect, the other a mechanical engineer. The two youngest are active high school students, who keep him busy. He enjoys learning about the Android apps his son develops and appreciating works of art created by his daughter. Sergio likes a good game of chess, reading historical fiction and working around his 1920s-era home. He combines his love for languages and engineering by translating technical documents from English to Spanish.
