Building Giants - Season 1

In Atlanta, Georgia, Mercedes-Benz Stadium is the world's most advanced stadium and features the most complex retractable roof ever built. The new home of the Atlanta Falcons will hold 75,000 fans and use the world's biggest scoreboard, a 360-degree, 62,000-square-foot video screen called a halo board. The construction crew races to finish the $1.5 billion stadium for the 2017 NFL season, facing deadly winds and unique engineering challenges.

Expert engineers try to build one of the largest and most advanced cruise ships in the world, the MSC Meraviglia. This goliath ship will carry over 5,000 passengers and pushes the boundaries of ship design and construction.

Engineers build a cutting-edge skyscraper in a busy area of New York City adjacent to the Museum of Modern Art. Known as 53W53 (or 53 West 53rd Street), this impossibly tall and thin tower must be built with a strange diagonal framework, posing unique challenges for some of the world's best builders.

Engineers race to complete the longest suspension bridge in the Arctic Circle before the brutal winter arrives. The E6 Halogaland Bridge Project involves the construction of the 1,533m-long (5,030 feet) bridge over Rombaksfjord in Narvik, Norway.

In Venice, Italy, a new 330-ton storm wall, part of the MOSE Project, is one of the strongest in the world, and it was built to protect the historic city from disastrous flooding.

Engineers are building a ground-breaking new railway line in Copenhagen, Denmark, that features 22 miles of tunnels, 17 brand-new stations, and cutting-edge driverless trains.

In Barcelona, Spain, the Sagrada Familia has taken more than 140 years to build; today, engineers are nearing completion of the world's tallest church (565 feet), designed by maverick architect Antoni Gaudi.
