IASS 2025 Mexico City October 27-31 Welcome! The International Association for Shell and Spatial Structures (IASS) gathers architects, engineers, and practitioners worldwide interested in conceiving, designing, and constructing shells and spatial structures. The last IASS Symposiums were held in Melbourne, Australia, in 2023 and in Zürich, Switzerland, in 2024. The next IASS 2025 Symposium will be held in Mexico City.

Mexico has already held two previous editions of this symposium, the first time in 1967 in Mexico City and the second in 2008 in Acapulco, Guerrero. The third edition will be in the historic downtown of Mexico City, the capital and largest cultural city, where you can find around 170 museums, 100 galleries, and 30 concert halls. Besides, Mexico’s gastronomy is worth trying.

Mexico City has plenty of examples of well-known reinforced concrete shells. Félix Candela, in collaboration with many other architects and engineers, constructed several hundred shells throughout the city and the country. Those interested in Candela’s legacy can visit these remarkable lightweight structures.

Welcome to IASS 2025, which will be held from 27 to 31 October 2025 and generate an exchange of knowledge. The latest scientific advances and cutting-edge technology will be available within a sustainability framework and care for natural resources.

The living past as a source of innovation

Mexico’s cultural richness and constructive tradition have gone hand in hand since time immemorial. This is how the past and the present coexist daily in our territories, architectures, structures, and spatial solutions. The IASS 2025 theme symposium, “The living past as a source of innovation,” will look towards novelty: learning from good construction practices and using the new technologies and materials of our time to project ourselves into the future.

What lessons can we transmit from the historical tradition, from projection, technical, geometric, project, and structural solutions? What can we implement in the future in a world in perpetual transformation? The invitation opens to a rich discussion and deep reflection: let us raise, listen, and learn together from experiences worldwide.
