How Did They Build That?: Season 1, Episode 8

1 - 8: Arctic Modules & Auditoria

Every construction job comes with obstacles...but some are much bigger than others. In this episode, we travel to the world's most extreme climate to see how engineers built the British Antarctic Survey, a research station that can move locations when danger strikes. Then we visit the Auditorio de Tenerife in the Canary Islands, with an exterior so revolutionary, a new machine had to be custom built to make it. Finally, we head to Scotland's Falkirk Wheel, a rotating boat lift that connects two canals with massive height differences.
