In 2002, Chinese engineers and workers tackled one of the biggest construction projects on earth, the Yangshan Deep Water Port. Thirty km out to sea, with 20 km of quay and fifty berths, Yangshan is destined to become the biggest deepwater port ever built. Linked to China by the world’s second-longest ocean bridge, Yangshan’s deep water allows the world’s biggest container ships to come calling. Its massive cranes, cutting-edge control system, and focused personnel are already shattering records for loading and unloading gigantic container ships and it’s not even finished being built.
Hoover Dam is regarded as an engineering masterpiece and an American icon. But what if it did not exist today? How would engineers build it today? In this one-hour program, we ask a team of engineers what they would do the same, and what they would do differently...as we re-invent Hoover Dam.

The 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.
In 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.
Designed by Cesar Pelli, the Petronas Towers were the tallest buildings in the world on the date of its completion. Located in Kuala Lumpur, the design of the 88 storey, 450m tall twin towers, carries an Islamic geometrical influence. The towers are a symbol of Malaysia’s pride. To instill competition, the contract for the construction of the towers were awarded to two different construction companies, each company was assigned to work on one of the towers. This episode takes a look at how the construction companies competed to complete their tower before the other. Problems faced, from the soil samples, the unique cement mixture used as a steel substitute, to the tropical weather, are covered.

In 1906, an earthquake of magnitude 7.9 rocked San Francisco. An earthquake of similar or greater proportions is expected to occur in San Francisco again, and soon. The episode takes a look at the efforts that are being made to retrofit and strengthen America’s most recognized bridge, the Golden Gate Bridge, before the next big earthquake happens. It also gives a brief history about the construction of the suspension bridge, and the people who were involved in its construction.
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..

The world's first electromagnetic levitation train linking Shanghai's airport and financial district offers a safe, energy efficient transport system that could change the face of 21st century travel.
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.
Megastructures will take you on a voyage through the largest ocean liner ever built, from the cutting of the first steel panel to the installation of the iconic red and black funnel of this 800 million dollar giant of the seas.

Perched 4,000 feet above the Colorado River on the very edge of the Grand Canyon is one of the most recent and innovative engineering marvels of our time. The Grand Canyon Skywalk, opened to the public in March 2007, is an engineering masterpiece united with natural wonder. It is the first ever cantilever designed glass bridge. Constructed in a horseshoe shape, visitors are given the chance to walk out over the edge of the canyon and look straight down. It's about 4,000 feet above the canyon, which is higher than any of the world's largest buildings and extends 70 feet from the edge. Take a closer look at the Skywalk's design, construction and the people that made it a reality.
Railroads are the backbone of American industry. 170,000 miles of track crisscross the country from coast to coast, moving two quadrillion tons of freight every year. But nothing lasts forever, and that includes a couple of 180-ton locomotives. Their engine technology is inefficient so they're headed for the scrap dealer where they'll be cut down and cannibalised. Any salvageable parts must come out intact for resale, while any leftover metals – like steel and copper – will be cut up, melted down and ultimately reformed into new products. In this business, nothing goes to waste. Take an inside look at the unknown world of scrap, where locomotives go to die and be reborn
Three teams of engineers are locked in a race to harness what may be the most powerful form of green energy: swift tidal currents and battering waves, the power of the oceans. Each team believes it can solve a portion of the world's energy needs. They're testing three different machines designed to be placed in the water and convert oceanic energy into electricity. But getting the machine from the design stage to implementation is a difficult challenge and now each team prepares to install their systems and turn them on for the first time. If they succeed, they could radically change the way we power our planet.

At 610m high the Guangzhou Sightseeing and TV Tower is the tallest television tower on earth and among the world's top ten tallest buildings. Tough enough to withstand typhoon, earthquake and other assaults from Mother Nature, this elegant building forced a rewrite of the rule books. A deceptively simple twist in the middle of the main 450m tower sets this super tall building in a mega class of its own and, proves a test of massive proportions for the team responsible for breathing life into the vision of Dutch architects Mark Hemel and Barbara Kuit.
For over 40 years the Big Red Box at Jackson Hole, Wyoming, carried skiers, hikers, paragliders and sightseers up to the 3,400-metre summit of Rendezvous Mountain. But nothing lasts forever, so when cable inspector Norm Duke found evidence of stress fractures inside the aging steel track cables, there was no choice but to tear down and replace Jackson's iconic aerial tram. At a cost of US$31 million, this two year construction project is a top-to-bottom, state-of-the-art replacement. It will operate in 120 kph winds and minus 30°C temperatures, all with the quiet precision of a giant Swiss watch. Construction crews battle a record-breaking snowfall, zero visibility, high winds and impassable mud-slick mountain roads to build its five towers and two terminals, and string more than ten miles of heavy steel cable as they risk their lives in a battle to finish before winter closes in.
