Big, Bigger, Biggest - Series 1

Examining the advances in engineering that made some of the world's most iconic structures possible.

How did Bridges evolve in size from tiny bamboo walkways spanning streams to super long suspension bridges connecting islands? How did Buildings surge in stature from ground hogging town houses to cloud busting skyscrapers?

In a landmark, four-part CGI-driven series, Big, Bigger, Biggest reveals the inventions that enabled structures to grow in size and scale. Each hour-long film unpicks the engineering evolution of a different iconic structure : Skyscrapers, Bridges, Aircraft Carriers and Airports. Each film opens showcasing the largest example of its kind and poses the question, 'how did it grow so big?'

Rolling back the clock and winding down the scale, we reveal the seven inventions that allowed these structures to gradually grow supersize…and the seven historic buildings they first appeared in. 50% of each film is CGI-animation. Superstructures grow, evolve, bend, twist, move and collapse to reveal their secret workings…and the story of how they evolved in size and scale.
