It’s no easy task to prepare a city for such big-scale events, but it’s a great opportunity for host cities to boost their economy and make a lasting impression on visitors. For most, the airport will be their first impression of the city, so host cities have vamped-up their airports with the help of steel.  

Take a look at the airports expecting the most traffic in the beginning of the year:

Guarulhos International Airport – Brazil

Every year, from February 24 to 28, the people of Rio de Janeiro hold the Carnival, which unofficially lasts from the end of December to March in the form of hundreds of street parties called blocos. In 2017, more than 1.1 million people showed up for the Carnival from all over the world and spent about USD 782 million during their stay. The Guarulhos International Airport (GRU) is the busiest airport in Brazil, and traffic has tripled from 12.9 million people in 2004 to 39.5 million in 2014. To accommodate the growing number of passengers, the airport has undergone several additions and renovations in the past couple of years.

Ahead of the 2014 FIFA World Cup, GRU built the 192,000 square-meter Terminal 3 to increase its passenger capacity by 12 million, bringing up the total capacity to 42 million. Terminal 3 consists of 2 main buildings made up of 40 metal modules weighing 70 tons each, held together by concrete pillars.

Then, in 2016, Terminal 2 was renovated ahead of the Summer Olympic Games to fit modern airport standards. With a budget of USD 50 million, architects took existing facilities that were close to 30 years old and rebuilt them into the modernized Terminal 2. The new terminal now accommodates plenty of retail space and a massive food court, and non-aeronautical revenues make up 51 percent of the airport’s entire revenue.

It seems the airport, and the city, made a lasting impression as last year, over 94 percent of tourists that took part in a survey said they would make another trip to the city and over 91 percent responded they would recommend Rio to their friends.

Louis Armstrong New Orleans International Airport – USA

The Louis Armstrong New Orleans International Airport (MSY) is another airport that sees millions of visitors every year during the month of February. Mardi Gras, or Fat Tuesday, landed on February 13 this year, marking the end of a month-long celebration. It’s basically the American version of the Rio Carnival, and social crews or Krewes organize different parties all over town. The event draws about 1.4 million participants on average.

Starting in 2016, MSY is working to complete a 972,000 square-foot North Terminal by February 2019. The project will cost about USD 1 billion to construct. When finished, the new terminal will include 35 new gates, a massive parking garage for 2200 cars as well as a central utility plant.

Besides increasing the passenger capacity, the project created about 64,000 jobs and generated USD 6.4 billion in local spending and USD 2.4 billion in local earnings. The project is also responsible for tons of steel consumption in the form of beams, bars and panels. On November 17, 2017, workers erected a steel beam at the highest elevation of the new terminal, signaling the project will most likely be completed on schedule.

Incheon International Airport – Korea

It’s not every year Korea gets thousands of visitors in the month of February, but as the host for the 2018 PyeongChang Winter Olympics, Incheon International Airport (ICN) is bustling with passengers. Global passenger flights were up 15 percent this year compared to last year, and up 24 percent in the U.S. alone. In Vietnam, bookings were up 550 percent from the previous year, the Philippines saw a 200 percent increase and Canadians booked 40 percent more flights, all in time for the 2018 Winter Olympics.

To greet the growing number of passengers, ICN completed its second terminal earlier this year using POSCO’s 446M steel. The same type of steel was used to build the first passenger terminal in 2001, but this time, architects decided to apply a special process called Bead Blast to create a rough texture on the roof of the terminal to minimize reflectivity as it can interfere with sight during take-off and landing. The steel also contains high amounts of chromium (26%) and molybdenum (2%), making it extra corrosion resistant.

As the #1 ranked airport in service quality for the last 10 years, ICN will now be able to service more passengers, 72 million to be exact, and 5.8Mt of cargo every year.

Airports play a central role in the tourism industry of its respective country, and the national economy as a whole. Steel continues to be the most widely-used construction material for the building and renovation of bustling airports around the world, and will continue to help cities make a lasting impression on all its visitors.

The budget for the entire event was estimated to be around USD 10 to 13 billion to get PyeongChang in prime shape to host more than 6000 athletes and officials from all over the world. As a result, the winter games will take place in 13 different venues, 6 of which have been newly built and the remaining 7 were renovated specifically for use during these games.

As the biggest steelmaker in Korea, POSCO played a crucial part in building the International Broadcast Center (IBC), Media Residence Hotel and the Kwandong Hockey Center with its World Premium Products and innovative construction solutions.

International Broadcast Center

This year’s Winter Olympics will set a new record as the first Olympics to be broadcast live in all U.S. time zones, and all of this will be coordinated through the IBC. POSCO custom-made H-beams for the center’s pillars and columns using Pos-H, a type of steel produced by precisely cutting and welding POSCO’s hot-rolled steel plates and thick plates together.

The HSA5-based Pos-H is seismic wave resistant and can be customized to fit specific height and thickness requirements for different parts of a building. Plus, compared to existing hot-rolled steel which only comes in a standard size, manufacturers have the added benefit of reducing the amount of steel used, thus saving costs.

POSCO also applied GI-Ace steel and fire-resistant cladding to the IBC’s columns to not only increase fire resistance but reduce construction time. POSCO’s dry fire-resistant cladding is different from traditional methods that require numerous layers of fire-resistant paint to be applied, requiring additional manpower and hours to complete. Dry-cladding can be wrapped around the surface of the columns in a one-time process.

Finally, the 5-story IBC is now capable of supporting a much larger load thanks to a new composite beam with concrete integrated into POSCO’s SM490 steel. Overall, POSCO supplied 8,218 tons of steel for the IBC.

Media Residence Hotel

The Media Residence Hotel is another important facility POSCO’s materials and construction solutions played a vital role in. POSCO wrapped the exterior walls of the 300-room, 4-story building with PosMAC, a magnesium alloy coating, that is 10 times more corrosion resistant than standard galvanized steel.

The interior walls are also lined with steel. Instead of wallpaper, the Media Residence Hotel is lined with a special type of printed steel that feels like fabric to the touch. POSCO also applied PosMAC to the modular bathroom floors instead of traditional tiles. PosMac is 5 times more corrosion-resistant than zinc plating, and has an aesthetically-pleasing finish. POSCO’s stainless steel, PossSD, made up other parts of the bathroom as it is also highly corrosion-resistant and workable. In addition, each entrance was made with POSCO’s high-strength and corrosion-resistant 329LD duplex stainless steel with surface treatment and color processing.

What’s noteworthy about this construction project is that 100 percent of the building was constructed off-site via modular construction. Compared to the time it would take to build a traditional concrete building of the same scope, the construction period for the Media Residence Hotel was 18 months shorter. Since each room is a relocatable building unit, it will be moved to a different venue and recycled as another hotel or dormitory. All in all, POSCO supplied 1,405 tons of steel for the entire construction project.

Kwandong Hockey Center

Kwandong Hockey Center will be home to some of the most exciting action of the winter games, and the facility was built on the “ice wave” concept to reflect the dynamics of ice hockey, waves of the nearby East Sea and the region’s strong winds.

Again, POSCO’s duplex stainless steel 329LD was used to cover the stadium’s exterior to protect against rapid corrosion that is prevalent in coastal areas. Aside from protection against corrosion, the stainless steel is extremely high in strength, allowing the builders to reduce the thickness of the steel plates by 25 percent compared to standard types of stainless steel.

POSCO also aided the construction process by providing additional support such as internal wind pressure structural analysis, surface treatment and a panel processability evaluation to maximize the benefits of POSCO’s products.

With these new and upgraded facilities completed, PyeongChang is now equipped and ready to host the 23rd Winter Olympics. The only thing left to do now is to witness history as the best athletes from all over the world compete for gold. Best of luck to all the Olympic and Paralympic athletes!
