If habitats are seen as the cells of life, everything else we build in the world that services and connect them must be seen as infrastructure. The range and variation boggles the mind, and so does the expertise required to design, build and maintain it. This gallery is the most eclectic and surprising of all.

As ENR closes the year with its fifth annual construction photography contest issue, the improving quality of the submissions is quite noticeable.

Global construction needs seemed almost insurmountable when taken as a whole.
