Sustainability and Resilience

  • 1.  Future of Civil Engineering .How Can We Build More Resilient Infrastructure?

    Hello everyone, πŸ‘‹

    As civil engineers, we face one of the greatest challenges of our time – designing infrastructure that can withstand climate change, rapid urbanization, and unexpected disasters.

     I'd love to hear your thoughts on:

    What innovative materials/technologies can make our structures more sustainable?

    How can we balance cost efficiency with long-term resilience?

    Do you know any great real-world projects that set a benchmark for resilient design?

    Since both resilience and sustainability are about long term performance of a structure, may be best to work with materials that have a good, lengthy track record.  Examples of these materials could be steel and concrete. The high carbon footprint of cement used in concrete can be reduced by using, as much as practical, alternate waste products such as fly ash.  Innovative materials/technologies are fine on a limited scale, but will they retain their advantages over time?

    Using proven materials, one simple way increase resilience is to design for somewhat higher loading than currently required.  This is (and has been done) for a long time for certain structures.  For examples, look at the four Risk Categories listed in the International Building Code (IBC).  Category IV (the highest) includes certain medical buildings, power generating stations, water treatment facilities, etc.

    By increasing gravity loading above the minimum, the chances for cost effective future modifications and adaptive reuse are improved.

    If appropriate, consider how flooding could get worse with climate change.

    Robert, I completely agree with your point about proven materials and the importance of long-term performance. At the same time, I think there is room for combining traditional materials like steel and concrete with modern technologies-for instance, smart monitoring systems or advanced coatings that extend durability. This way we can keep the reliability of established materials while still pushing resilience further.

    Darya, good point.  Most successful projects have a suitable combination of components.  Perhaps the OP's question could be revised to request comments on the "best" materials/technologies recommended for sustainable/resilient structures.

    Concerning proven preservation of above ground structural steel the "best" that I am aware of is a combination of old and new technology:  Hot-dip galvanized steel (a process largely unchanged in 150 years) coated with properly selected and applied modern high-quality "paint".

    Great questions, Saif! In my view, resilient infrastructure will come from a mix of innovative materials and smarter design approaches. For example, modular and adaptable structures can extend service life, while using low-carbon materials such as recycled aggregates or geopolymer concrete reduces environmental impact. Balancing cost and resilience often comes down to considering lifecycle costs rather than only upfront investment.
