Novel construction materials may help address some of challenges of urban infrastructure development. But dramatic progress may be possible only by developing entirely new construction methods. Most of the basic methods of manual construction have been around for centuries — even millennia. Advances in computer science and robotics should make more automation possible in construction, for instance, greatly speeding up construction times and lowering costs. Electricity networks linking large central-station and decentralized power sources will also benefit from greater embedded computation.
All of these endeavors must be undertaken with clear vision for the aesthetic values that go beyond mere function and contribute to the joy of living. Major bridges, for instance, have long been regarded almost as much works of art as aids to transport. Bridges, buildings, and even freeways contribute to the aesthetical appeal of a city, and care in their design can contribute to a more enjoyable urban environment.
In previous decades, much of the rest of urban infrastructure has been erected without as much concern for its impact on a city’s appearance and cultural milieu. Recently, though, awareness of the aesthetics of engineering has begun to influence infrastructure design more generally. Integrating infrastructure needs with the desire for urban green spaces is one example.
Projects to deal with urban stormwater runoff have demonstrated opportunities to incorporate aesthetically pleasing projects. Using landscape design to help manage the flow of runoff water, sometimes referred to as “green infrastructure,” can add to a city’s appeal in addition to helping remove pollution. The vast paved area of a city needs to be rethought, perhaps by designing pavements that reduce overhead temperatures and that are permeable to allow rainwater to reach the ground table beneath. Proper engineering approaches can achieve multiple goals, such as better storm drainage and cleaner water, while also enhancing the appearance of the landscape, improving the habitat for wildlife, and offering recreational spaces for people.
Rebuilding and enhancing urban infrastructure faces problems beyond the search for engineering solutions. Various policies and political barriers must be addressed and overcome. And the practice of letting infrastructure wear out before replacing it, rather than incorporating technological improvements during its lifetime, only exacerbates the problems.
And so, a major grand challenge for infrastructure engineering will be not only to devise new approaches and methods, but to communicate their value and worthiness to society at large.
