Jon argues that the industry should stop designing only for age and start designing around use, performance, maintenance cycles, and accountability. Maybe a 20-year design life with zero maintenance is harder, and more honest, than a 100-year design life nobody is around to answer for. WHAT YOU’LL LEARN · Why Dr. Jon Belkowitz questions the 100-year design life · What Hoboken, New Jersey teaches us about old infrastructure · Why designing for time may not be the same as designing for use · The…
