The world's first rock and roll theme park: Hard Rock Park in Myrtle Beach, SC. Unforeseen problems and one-of-a-kind rides like Maximum RPM threaten to keep the veteran crew from finishing in time for the grand opening.

The world's biggest cargo ship is being built in Denmark, by Danes who trace shipbuilders in their family trees to the Vikings. With just 45 days in the drydock to complete this mammoth ship, can the team overcome problems and delays to finish on time?

In South Korea engineers are fighting against the forces of the wild West Sea to build the Incheon Grand Bridge. It's part of a visionary plan to link the biggest airport in the nation, with a new international investment zone called New Songdo City. The unique structure combines three methods of bridge construction to create a single highway 12.3 kilometres long. As they fight the elements to build up Incheon Grand Bridge, they prove the strength of human determination.

In Las Vegas -- the quintessential city of razzle-dazzle and bling -- MGM is going for the ultimate one-upmanship. The Hollywood lion is building a 31-hectare mini-city with all amenities for those living there or visiting. It'll cost a cool $9 billion -- the largest privately financed project in North America - ever. This is a story of a massive project being built in a very short time.

It will be one of the world's few floating bridges, built on concrete pontoons as long as football fields. Although the team is made up of veterans, none of them have ever built a floating bridge. Will delays keep them from finishing on time?

The Aker H6e is the biggest oil rig on the planet - built for the extreme conditions of the Barents Sea. Marine operations chief Knut Engebretsen and his team have tight deadlines for some major moves to put this monster together. They have to "skid" eight-thousand-ton hull pieces on rails across a giant yard. The steel deck that goes on top of the hull weighs more than 11,000 tonnes. Raising it up in the air 10 storeys will be one of the most extreme heavy lifts ever attempted. On top of these mega-challenges, this hardy crew of Norwegian engineers has to battle bad weather all the way.

It's the ultimate engineering challenge: rescue the magnificent city of Venice, Italy, before it is drowned by the Adriatic Sea. A fantastic 5.5 billion dollar plan is taking shape. It's called the "Mose project", after the biblical saviour Moses. They're constructing 78 massive floodgates, up to 29 metres tall, that will lie on the seabed. Whenever a dangerous high tide threatens the city the gates are supposed to rise from water and hold back the sea. The dynamic woman at the helm; Chief Engineer, Dr. Maria Theresa Brotto, declares, "Without the Mose, we will lose Venice." But no one can predict when a colossal high tide will swamp the city and it's a race against time for the workers of the Mose project.
