  • MEGASTRUCTURES

DESCRIPTION

We focus on modern-day miracles of construction. Superhuman feats of modern engineering from around the world.

In Megastructures: Panama Canal we meet the mother of all mega-movers. Every year this strategic waterway lifts 14,000 ships over the equivalent of a nine-storey mountain range. Relying on some of the mightiest machines and feats of engineering in the world, the demands for its services are high, and now there are plans afoot for an even bigger, better canal.

Megastructures: Deep Sea Drillers follows an attempt to tap some of the most inaccessible natural gas on the planet, in which five high-tech mega vessels will complete a 1,800 square mile gas network, over a mile and a half below the ocean’s surface. At the heart of the project is the enormous gas-processing platform, the Independence Hub. If successful the system will produce enough gas to supply nearly 5 million households in the US.

Megastructures: Iceland’s Big Dig takes us six hundred feet underground in Iceland’s remote Eastern highlands to a gigantic Tunnel Boring Machine called Jaws. After two years of constant grind, "Jaws" has bored a tunnel over twenty-five feet in diameter nearly nine miles through basalt. This tunnel is the linchpin of a massive Hydro-Electric project that plans to use the melt water from a massive glacier to make electricity. One of the biggest challenges is steering this monster machine in a straight line, so that after nine miles eighty-eight yards it hits target dead centre. Will "Jaws" Breakthrough or bust?

Megastructures: Super Pipeline looks at one of the gas industry’s riskiest projects ever undertaken. By 2008, Britain will be connected to Norway via a 1,200 km super pipeline. It’s composed of over one million tonnes of steel and equating to a 1/3 of the world’s combined pipeline production company. Yet all of the work must be completed by robots working 3 km under the North Sea against harsh underwater currents, sub-zero temperatures and abysmal wind and wave conditions.

They span acres of land and consume enough electricity to power small towns. Megafactories are some of the most unique production facilities on Earth. We visit Italy’s Ferrari factories, to witness the construction of the Ferrari 599 from molten metal through to its 200 mph test drives, and learn how Formula One technology is transferred onto the production line. Then to Ohio and Texas, to see how tanks can be stripped down and rebuilt from the ground up, rather than built from new. In combat they are weapons capable of destroying targets two miles away. Finally, Apache Helicopters are perhaps the most lethal attack helicopters in the world. We visit the Boeing plant in Arizona, to see how sophisticated military technology is helping to make sure that the Apache pilots make it back home.

Take an eye-popping look at the greatest structures and machines ever created.

The Harley-Davidson is an American icon. We go behind the scenes at the Harley-Davidson HQ to discover how this particular mega factory is able to rev up 50 new Harleys every single hour, and get an inside peek at the process to create the controversial newly designed V-Rod. We also visit the John Deere factory, which covers more than 300,000 square metres, houses more than 2000 employees and 49 robotic welders. Find out how all these elements combine to help stamp, press, cut and weld 60,000 tons of steel into the John Deere STS Combine – a harvesting mega-machine. Finally we travel to the Peterbilt factory where workers are busy building Model 387 trucks, made to pull vehicles weighing up to 36 tonnes. With its mechanical brute strength and human creativity, this mega factory brings Peterbilt’s aerodynamic king of the long-distance fleet to the road.

  • Megastructures: Air Force Transport
    Need another tank or two in the Persian Gulf region? How about a half-dozen helicopters in a hurry? More munitions by Monday? If you're a U.S. military commander, chances are Dover Air Force Base in Delaware can deliver. It's the busiest US military aerial port. Responsible for more than 30 % of US military materials sent overseas, Dover AFB is the lifeline providing supplies to American troops abroad. And with the United States in Iraq and Afghanistan, operations have doubled. On an average day, lines of tractor-trailers stretch up to two miles from the giant aerial port, waiting to disgorge their contents into a cavernous warehouse next to the airstrip. More than 600, 000 pounds of cargo pass through Dover AFB every day. Almost nothing sits for more than 24 hours. Provisions include food, construction supplies, fuel and military firepower. Shipments are filled with a dazzling array of the latest in high-tech defense equipment- and the shipments are huge. Tank battalions, jet squadrons, and an army's worth of munitions all pass through Dover to be flown overseas. This is a shipping operation on a massive scale, and it uses massive machines to get the job done. The star in Dover's arsenal is the Galaxy C-5, the largest airplane in the U.S. military. Until you've seen a C-5 up close, it's impossible to comprehend the enormous size of this Mega Mover. It's as long as a football field and stretches six stories high. Specially designed to transport the latest in military fighting equipment, a single C-5 will frequently carry a Herculean load: eight F-5 fighter planes, two Abrams battle tanks, and seven Huey helicopters can all fit inside. Flying with a full load requires a lot of fuel. The C-5 uses 51,000 gallons of fuel-enough for an average car to make 31 trips around the world! The C-5 is an aircraft so large many people said it could never be built, but in 1965, the Air Force decided to try.

  • Megastructures: Dubai's Dream Palace
    Measuring more than 320 metres high and stretching higher than the Eiffel Tower, Dubai's Burj Al Arab is an architectural icon for the 21st Century. Rising out of the sea like a proud ship at sail, the Burj pushes the boundaries of engineering to the limit. How does a bold young design team that has never built anything taller than 16 stories tackle building the tallest and most luxurious hotel in the world? To start, the team creates an artificial island 270 metres off the coast of Dubai. Engineers utilize ground-breaking concrete blocks to reduce wave impact and prevent water from flooding. To protect the Burj from the elements, architects create a visually stunning exoskeleton with trusses longer than an Airbus 380 and heavier than 20 double-decker busses. However, the team receives devastating news that threatens the Burj's entire exoskeleton. Engineers must design an ingenious way to counteract 'mini-tornadoes' that threaten the hotel's structural integrity. The architects must also create a gravity-defying restaurant that is suspended 200 metres above the sea and nearly 20 metres out on both sides from the building's narrow core. Expert testimony, CGI and footage of the Burj throughout the building stages follow the birth of this historic triumph.
  • Megastructures: Panama Canal
    Meet the mother of all Mega Movers: the Panama Canal. Lifting a mind-blowing 14,000 ships a year, the Panama Canal relies on some of the mightiest machines in the world: gargantuan locks, a colossal crane, and the worlds largest dipper dredge. This is one of the trickiest waterways in the world, but thousands of ships risk it every year to deliver their goods faster. Demand is so high, traffic never stops and plans for a bigger better canal are underway. Can this mega mover handle the pressure?
  • Megastructures: Port of Rotterdam
    The Port of Rotterdam is a freeway. Every day 450 ships go in and out of here carrying one million tons of cargo worth a staggering one billion dollars. It's not only the biggest port in the world; it's one of the most difficult. Traffic, vicious currents, narrow channels and the biggest super tankers in the world make it a mega operation where the stakes are high, the potential for disaster ever present. To survive, the Port of Rotterdam assembled a fleet of monster tugs and the biggest cranes and unloaders the world has ever seen. The Jumbo Javelin tanker is massive - almost five football fields long, with 700,000 cubic feet of storage space -- the volume of six Olympic swimming pools combined. It's the strongest ship on the high seas and it's unwieldy. To get into Rotterdam it must run the Calandlkanaal, a narrow channel with a brutal undertow. And that's where the "RT Magic" comes in. 5100 horse power packed into just 90 feet of ship, "The Magic" can manhandle a tanker 350 times its own weight. Conventional tugs push or pull. With its revolutionary Voith-Snider drive system, "The Magic" can haul in any direction - even sideways - and turn on a dime. No propeller here. This monster is driven by ten feet high blades that look like an eggbeater giving "The Magic" the stunning ability to stop a super tanker dead, and respond like a dancer to Rotterdam's ripping undertow. "The Magic" needs every advantage it can get. In November 2002 the deadly undertow rammed the 350-foot "Hellenic Star" off course. It plowed into the 550-foot "West Trader," holing it and nearly sinking the Hellenic Star. Damage was in the millions. But "The Magic" isn't alone. High above downtown Rotterdam is one of the most sophisticated navigational computer systems in the world that tracks every ship in the Port to within three feet of its actual position. The World Port Center looks like mission control at NASA, dominated by a two-story high video screen and an army of watchers.
  • Megastructures: Super Pipeline
    By two thousand and eight, Norway will be connected to the United Kingdom via a 1200 km super pipelinethe longest subsea pipeline in the world. But this connection is only a part of an enormous plan to tap into Norway's second largest gas deposit, capable of providing 20% of the UK's gas needs for decades to come. Located 3 km below the ocean's surface and 120 km offshore, the deposit is beyond the reach of humans and all of the construction has to be completed by robots working against strong underwater currents, sub-zero temperatures and extreme wind and wave conditions. When tapped, the gas will be transported to one of the largest automated gas processing plants to prepare it for shipment to U.K. Each phase will put ingenuity and engineering to the ultimate test.
  • Megastructures: Kansai Airport
    The Kansai Airport in Japan is considered to be one of the great engineering achievements in the world, second only to the Panama Canal. It is a "State-of-the-Art" facility that handles over a million passengers a week. It has all the operational problems of a normal International Airport, but on top of that it has to contend with typhoons, earthquakes and to top it all off¿ it's sinking! We will go behind the scenes to figure out how this feat of engineering works.
  • Megastructures: Airbus A380
    Airbus 380 The world's largest passenger plane is under construction and set to take to the skies in 2006.

Building it requires a worldwide mega-factory and a transportation route the likes of which have never been seen before. Will the A380 be the future of aviation or will it be the biggest boondoggle in aviation history?
  • Megastructures: Sea Launch
    The two giant ships of Sea Launch, a NASA-like mission control and a launch pad floating on the ocean, form part of an audacious, outrageously expensive, multi-national venture for blasting commercial satellites into space. The plus side: it's a very effective way of launching satellites into geosynchronous orbit (allowing the satellite to keep pace with the earth's rotation). The minus side: it cost over a billion dollars, it's never been done before, and it's riddled with challenges. The tale of Sea Launch involves spectacular engineering successes, the launch of the heaviest commercial payload in history (weighing nearly six tons), and a couple of costly failed launches.
  • Megastructures: Dubai's Palm Island
    An enormous project is underway in the Arabian Gulf that will literally change the face of the coastline. It's so vast it can be seen from space. Large artificial islands are being constructed and fashioned in the shape of massive palm trees.

  • Megastructures: Akashi Kaiko Bridge, The
    The Akashi Kaikyo Bridge: It's the world's longest suspension bridge - a third longer than any constructed before. Its also the tallest and the most expensive suspension bridge ever built. But it's built in a place where no bridge should be. Japan's Akashi Strait is a deepwater channel beset by typhoons; heavy rain; treacherous currents and to make things worse, it is built in the middle of a major earthquake zone. Midway through construction the bridge was hit by the full force of the Kobe earthquake. Incredibly, construction is only delayed by a month. The bridge has been open and trouble-free for six years. But could it one day fall down?
