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.
Super Carrier: USS Ronald ReaganJan 1, 2004 · 47mThe USS Ronald Reagan is a 4.5 billion dollars Nimitz-class supercarrier. Powered by 2 nuclear reactors, the 1100ft. long vessel is equipped with all the necessary facilities to house 6000 personnel and over 80 aircraft. Viewers are given an exclusive look at how the crew of these ‘floating naval base’ is put through a series of test in order to obtain their flight deck certification. Take a glimpse at the various facilities on the ship that keep the 6000 strong crew fed, rested, and entertained.
AutobahnSep 19, 2004 · 60mWhat began as a racing track, and thanks to Adolf Hitler’s World War II propaganda efforts, the track grew into a sophisticated high-speed road system, linking to almost all the major cities in Germany.
The Autobahn boasts of having super thick road beds, 4% or less grades, wide lanes, and build on layers of technology.
The Autobahn allows vehicles to travel at speeds exceeding 160km/h for roughly 2/3 of its roads.
The episode profiles the operations of the highway cops, and their reliance on technology in training, monitoring of roads and various methods of arrest.
It also looks at the ADAC, an automobile club, which provides on the spot road assistance. Nicknamed ‘The Yellow Angels’, they also provide air medical rescue. The system of maintenance of the Autobahn is also examined.
All this infrastructure makes this mega structure into one of the world’s most safest super highway.
Channel TunnelSep 22, 2004 · 60mThe Channel Tunnel or Euro Tunnel is one of the world’s longest underground rail tunnels, and links England with France. Consisting of two rail tunnels and a small service tunnel in-between, they total 153 km in length. The documentary looks at the race between the British and the French to complete the tunneling of the Channel Tunnel and the obstacles faced in its construction.Sears TowerSep 29, 2004 · 47mFor 20 years, the Sears Tower held the record for the world’s tallest building. Completed in 1973, the 110 stories high building is almost half a kilometer tall. And it still holds the record for having the world’s highest antenna. John Zils, structural engineer and designer of this mega-structure shares some of the secrets about the tower. And get a behind-the-scenes look at some of the various systems and controls that are vital to the building, like security monitoring, the elevators, and the water and power distribution to the various levels, and even the machines that cleans the windows.Kansai International AirportOct 13, 2004 · 47mLocated 5 km off the coast of Osaka, Japan, is the Kansai International Airport. The airport is built entirely on a man-made island, 4 km long and 1 km wide. The only link between the island and Osaka is by the world’s longest 2-tiered bridge. Although the airport is built to withstand earthquakes and typhoons, the artificial island itself is sinking faster than anticipated. The episode looks at the various measures that are taken to keep the airport ‘afloat’, and the various facilities and services available to keep the airport running.Akashi Kaikyo BridgeOct 20, 2004 · 47mIn 1955, two ferries sank along the Akashi Strait, Japan, killing 168 children. It led to a 30 year research on designing a bridge that would link the Awaji Island to Kobe; the bridge would also have to be able to withstand severe earthquakes and typhoons, a norm in that area. In 1988, Japan began construction of the world’s longest, highest and most expensive suspension bridge, the Akashi Kaikyo Bridge. The episode presents a stage by stage look at the construction of the suspension bridge, and the obstacles faced in its construction, including the Kobe earthquake in 1995.
