Located near Johannesburg, South Africa, the Tau Tona is a gold mine. The Tau Tona is the main economic life blood of Johannesburg, supplying half the world’s gold needs. It is the deepest and largest working mine in the world. Its main shaft is 3.6 km deep and consists of 800 km of tunneling. This episode gives viewers a tour of the dynamic systems involved in maintaining a working environment deep in the earth. It also provides a glimpse of what life as a mine worker is like in Tau Tona. Risking heat exhaustion, and with 10 earthquakes a day, the miners work through narrow tunnels to extract gold from a 25 cm thick gold vein.

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..

Power systems and infrastructures that keep Las Vegas glittering are examined.

Located in Alberta, Canada is the world’s largest known single deposit of oil worth trillions of dollars. However, the oil is trapped in a complex mixture of sand, water and clay, and the cost of extracting the fuel from the soil will cost billions. The episode profiles the competition between the Syncrude and the Shell Oil companies to extract the black gold. It looks at the various mega machines and systems that are used to extract, transport and the process used to separate the oil from the sand.

A satellite delivered by a rocket that is launched from the earth’s equator instead of any other place, can have its lifespan extended for as much as 3 years. This would mean huge savings for the companies that own these satellites. Thus the Sea Launch was constructed. The Sea Launch is made up of 2 megastructures, a floating launch pad called the Odyssey and a shipping vessel called the Commander. The episode gives a brief history of the construction, the successes and the failures of the Sea Launch.

'National Geographic Channel MegaStructures' takes a look at the construction history of Boston Big Dig project. Costing almost 15 billion dollars and taking almost 20 yrs to complete, the Boston's Big Dig is considered to be the most complex, expensive, and technically challenging civil engineering public works project in the United States. The project was inspired by Fred Salvucci, the Transportation Commissioner to the Mayor of Boston, who wanted to find a solution to the city’s traffic woes. He came up with an idea to link up the major sectors of the city with a system of wide underground tunnels for traffic. Consisting of 4 elements, a tunnel under the harbor, an underground connection to the Interstate 90, an underground traffic system under the city itself to replace the elevated city highway, and a wide cable-stayed bridge to replace the old double-decked bridge. The episode looks at the many obstacles that were faced in the construction, from water leaks to residential protest. The episode also contains brief words from some of the major people involved in the project.
