MegaStructures - Season 5 - Eps 4: Beijing Water Cube
Just in time for the 2008 Beijing Olympics, workers are feverishly putting the finishing touches on the National Aquatics Centre – the Beijing Water Cube. A stroke of design genius, this Olympic Megastructure is a steel honeycomb-like frame enclosed entirely by a unique skin, modelled after soap bubbles. Using 90 kilometres worth of steel in 22,000 beams following no conventional straight lines, the Beijing Water Cube must be topped with 100,000 square metres of bubbles. Looking for a truly unique covering, the design team focuses on ETFE – a light-weight plastic invented to protect spaceships from cosmic radiation. Among ETFE’s unique properties, dot patterns on its surface can trap solar energy in the winter and reflect solar energy in the summer, keeping the building cool. The Beijing Water Cube is the largest ETFE construction in the world, and because of its honeycomb-like structure, 3,500 ETFE bubbles must be cut individually, and sized. Factor in that the dimensions have been created in Germany and must be translated into a Chinese database and the Beijing Water Cube becomes a bit of a logistical nightmare. Beijing’s Water Cube represents a true morphing of molecular science, architecture and structural engineering.

Synopsis
MegaStructures is a documentary television series appearing on the National Geographic Channel in the United States and the United Kingdom, Channel 5 in the United Kingdom, France 5 in France, and 7mate in Australia. Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products. Generally containing interviews with designers and project managers, it presents the problems of construction and the methodology or techniques used to overcome obstacles. In some cases this involved the development of new materials or products that are now in general use within the construction industry. MegaStructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first. This type of project is known as a Megaproject.
