A historic and present look at Holland's efforts to hold on to their precious land from floods as a result of rising sea levels and climate changes. After a storm in 1916, the Dutch began a labor intensive construction of a Barrier Dam in 1923, stretching 30 km in length. It resulted in the reclamation of 165,000 ha of new land, and creation of a fresh water lake. However, in 1953, a combination of a hurricane and high spring tides caused the North Sea waters to force through the barrier and flood the Dutch coastline, resulting in the loss of over 1,800 lives and 47,000 livestock. The disaster resulted in Holland's creation of the 'Delta Project'. Costing billions of dollars, the project began in 1958. The project consisted of the construction of concrete dams, steel sea walls and retractable floodgates. Environmental considerations also led to the construction of the storm surge barrier in the Eastern Scheldt, one of the biggest in the world. It consists of 2 floating gates built on special docks. The vast gates are controlled by a computer system that allows the gates to be kept open but closes when a flood is imminent. Also presented are current emergency plans that include allocation of certain areas of land to be flooded during worse case flooding..

Megastructures heads to the tiny desert kingdom of Dubai to explore the remarkable engineering behind the seven-star Burj Al-Arab Hotel. Five years in the making, this striking building stands like a gigantic white sail off the shore of Dubai. As this programme reveals, a refusal to compromise on the part of the hotel’s young designers ensured that the project pushed the boundaries of design. The Burj Al-Arab was envisaged by Dubai’s crown prince, Sheikh Mohammed bin Rashid Al Maktoum, as a means of diversifying the country’s economy away from oil into tourism. The Sheikh dreamt of a luxury hotel that would put Dubai on the world map, and surprised many by choosing a relatively inexperienced British firm to supply the design.

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.

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.
