With its vibrant diversity of attractions and facilities and the ground-breaking design that creates maximum visual impact, Singapore's Marina Bay Sands development is bound to become a timeless landmark. Seldom before have so many challenges been encountered by engineers and builders. As the complex involves hotel towers, a museum, casino, waterfront promenade, theatres and a skypark - all being worked on simultaneously, it is one of the largest and most complex construction sites that engineers ever had to deal with.

Dubai is on a mission: to become to top tourist destination on the planet. This Emirate has almost tripled its coast line, by building a palm-shaped city at sea. Now Dubai plans to put itself firmly on the map by recreating the world, three hundred man-made islands constructed out in the Arabian gulf. It’s the biggest reclamation project ever undertaken. The world can only be built of natural elements they demand by the shape. But it must define nature’s most destructive force: the sea. Engineers will battle against time and nature to create this man-made wonder visible from space. But will this creation of this mega structure push Dubai to the limit?

We look 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.

Take an eye-popping look at the greatest structures and machines ever created as we focus on some of the world's modern-day miracles of construction. Go behind the terraces to see how World Cup football fever has transformed South Africa's infrastructure and resulted in the creation of some truly stunning stadiums. In The Golden Train meet the 10,000 plus staff who worked on 65 separate sites to develop Africa's first high-speed railway network in time for the 2010 World Cup. South Africa Stadiums witnesses the challenges faced by construction teams as they battled against a very bad rainy season and stormy conditions to produce new stadiums in Soccer City and Cape Town.

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.

World's Largest Casino follows the construction of the world's biggest casino and its second biggest building. It's being sited in Macau, in Southern China, which is being groomed to be Asia's capital of gambling. The Venetian is to be built by the Sands Corporation of Las Vegas, and is to feature a giant hotel with 3000 suites, a 15,000 seat arena, a theatre, event halls, 350 shops along indoor canals hundreds of metres long, an outdoor lagoon for gondola rides, and above all, a huge casino floor the size of eight football pitches. We follow the reclamation of land between two islands for this project, and watch it fly up in record time due to special working methods being devised – from on-site factories, to having prefabricated parts trucked in from China. We see how the ambitious designs are brought to reality, despite the pressures and an environment that's very different from America, both in terms of climate and culture. We go in-depth into the amazing concern for detail in the outfitting and decoration which will turn a giant concrete conglomeration of structures into a place designed to entice people to stay as long as possible. Andwe meet the people responsible for putting the project together, and see how they co-operate to get the resort open on time. But will the public come to visit this US$2.4bn megastructure? There's no guarantee...

For years, when a jumbo jet reached the end of its 30-year lifespan, it'd end up in a scrap yard, or rotting at the end of a runway. But at the Evergreen Air Center in Marana, Arizona, planes past their prime are recycled instead. We'll witness each step.

The Piacenza bridge, 40 miles south of Milan. This steel and concrete bridge3 has connected the cities of Piacenza and Lodi, spanning a remarkable 3,300 feet across the Po River. But in 2009, a dangerous flood causes the Po's water level to rise more than 20 feet. On April 30th, disaster strikes: The northern end of the bridge collapses, taking with it four vehicles. The bridge has now become the latest challenge for a team of Italian deconstruction experts. With a radical plan, state of the art machinery, and a recycling mandate of 90%, Despe Demolizioni Speciali will have just 90 days to break this bridge12 down to make room for a new one.

In the intense glare of the Texas sun, a team of demolition experts attempt to cut down and recycle the Navy's "first and finest fast attack oiler," the U.S.S. Savannah AOR-4. This tough tanker ran fuel between the ships of the fleet for over 20 years. But now, she's making her final voyage to ESCO Marine, a sprawling scrap yard in the Southern most tip of Texas. Here, she'll be stripped down, gutted out and recycled. But the "Savy Sue" comes with an awful lot of challenges for ESCO owner Richard Jaross and his team. Asbestos, PCBs, and a decade of neglect make this once proud tanker one big mess.

For over 12 years, more than 2500 people have been working at temperatures above 40 degrees centigrade, on a project that’s intended to become a national icon. The construction of the Sheikh Zayed Al Nahyan Grand Mosque in Abu Dhabi is destined to be the biggest mosque in the United Arab Emirates. The construction is a huge multi-national undertaking bringing together designers, features, materials and suppliers from nearly every corner of the globe: Italy, Germany, Morocco, India, Turkey, Iran, China, Greece and the UAE. The final result is nothing short of spectacular, not only in sheer size, but also in architectural and creative beauty; this is not just a mega structure but an artistic statement on a massive scale.

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.

This is the story of the battle to build a railway across one of the most extreme environments on Earth. To lay down over a thousand kilometres of track in a remote wilderness. To drive 7 tunnels and to raise 675 bridges all at an altitude where even a simple breath is nearly impossible to come by. 140,000 workers and 2000 medics struggled for 5 years to conquer this hostile environment to complete. the Qinghai-Tibet railway, the highest, most extreme railway in the world!
