In the quest to build better for the future, some are looking for answers in the long-ago past.

Ancient builders across the world created structures that are still standing today, thousands of years later — from Roman engineers who poured thick concrete sea barriers, to Maya masons who crafted plaster sculptures to their gods, to Chinese builders who raised walls against invaders.

Yet scores of more recent structures are already staring down their expiration dates: The concrete that makes up much of our modern world has a lifespan of around 50 to 100 years.

    It seems like we build with a 50 to 100 year lifespan in mind. If I’m wrong please correct me. I wish some of our infrastructure, bridges especially, could be built with a long lifespan in mind.

      It’s an inherent problem with reinforced concrete. We couldn’t build the same structures without it, and it only lasts so long.
