Urban infrastructures provide comfort to inhabitants and mitigate the risks of disasters such as flooding. Underground systems specifically conceal urban infrastructures from public view and are configured as real mazes under the streets. The distribution of drinking water, urban drainage, sewage, and even electrical wiring and fiber optics in some cases, pass under our feet without us noticing. To this end, the industry developed precast concrete parts for about 100 years that provided construction speed, adequate resistance to force, and durability against time. Concrete pipes with circular sections, in many diverse diameters, are perhaps the most used conduits and are ubiquitous around the world. But there are also those who use these apparently functional elements in creative architectural contexts as well.
