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.

The future may look uncertain for commercial aviation, but the increasing demand for passenger flights, the need for new aircraft as well as new innovations are expected to stimulate the industry in 2018 and beyond.

Smaller planes, more frequent miles

City pairs, or pairs of departure and arrival airports, are growing around the globe. According to Aviation Week Network’s 2018 Fleet & MRO Forecasts, South Asia’s routes will increase from 650 in 2006 to 1200 by 2026. African routes will expand from 1400 to 2600 in the same time frame and Russia and the CIS region will see an additional 1000 routes by 2026.

For such city pairs, 100 to 150-seat aircrafts are ideal, and airlines will opt to add more of the crafts to their fleet over larger crafts that are hard to fill.

The growing global demand for passenger flights will further contribute to the need for more small-sized planes. In 2016, a total of 3.8 billion passengers flew the skies, and the number is projected to reach 4.3 billion in 2018.

Out with the old, in with the new

In the next 20 years, most of the existing fleet of aircraft will retire, and be replaced with new aircrafts. This will create an increased demand for airplane parts, new technology and labor. The overall volume of the global fleet will increase at an average yearly rate of 3.1 percent, and a major bulk of the supply is projected to come from the Asia-Pacific region.

To add, the cost of maintenance, repairs and overhaul (MRO) for aircrafts older than 10 years will reach USD 1 trillion for the first time ever, creating more business opportunities for suppliers and service providers.

Military aircraft will play its part in the Aviation Industry

In the U.S., the government is planning to spend USD 400 billion on fifth generation F-35 fighter jets made by Lockheed Martin Corp, and 11 other countries are currently working out a purchase deal worth over USD 37 billion.

Moreover, USD 67.3 billion is projected to be spent on the MRO of the world’s military aircraft, up 14.9 percent from USD 58.6 billion in 2008. With increasing tensions all over the world and subsequent rise in defense spending, demand for military aircraft will likely continue.

And then there’s flying cars

Although not traditionally counted as part of the aviation industry, flying cars are popping up in cities around the world and blurring the lines that define different transportation industries. With increasing investment, flying vehicles may become a reality in the next couple of years, and most will be flying on clean fuel. Here are some companies with plans to launch flying cars.

Uber

Uber recently announced its partnership with NASA to develop an electric aircraft taxi service called UberAIR, planned to be up and running in 2020. If successful, the vehicle will be quieter than a helicopter, travel up to 150 mph and charging will only take about 4 minutes. Uber has plans to test the service shortly in L.A., after successful trials in Dallas and Dubai. If all goes well, travel time in L.A.’s rush hour can decrease by a third.

Airbus

Airbus is looking to launch their CityAirBus in the skies for taxi service in 2018. The all-electric vertical takeoff vehicles will transport people up to 80 mph over congested traffic to destinations like rooftops, train stations and airports. The vehicles can carry up to 4 passengers at a time and travel up to 80 mph. In the beginning stages of its launch, Airbus plans to have a pilot on board the flights over fixed routes, but will work towards autonomous operations.

Volvo

Geely, which is the parent company that owns Volvo, recently purchased a flying-car startup, Terrafugia. The company aims to have its flying cars in operation by 2019, with a range of 400 miles on a single charge and travel speed of up to 100 mph. Terrafugia already received the U.S. Federal Aviation Administration’s (FAA) approval to start flying. They are also working on their next model, the TF-X, which can fly up to 200 mph and will cost around EUR 180,000.

The aviation industry will see many changes in the coming years. Although steeply rising oil prices will play a major factor in the profitability of the industry, the rising demand for passenger flights, increased military spending and new innovations will lead production and create new business opportunities for 2018 and beyond.

Stephen Zoepf is the executive director at the Center for Automotive Research at Stanford University.

To kick off the forum, Stephen Zoepf, executive director at the Center for Automotive Research at Stanford University gave a presentation called “Electric Vehicles: Adapting to a Changing Marketplace” to share his insights on what future markets will look like and implications for automakers, suppliers as well as consumers.  

Here are the key takeaways.

The Future is Going to Look Very Different

According to a report by RethinkX, an independent research group, 6 trillion U.S. passenger miles will be driven in 2030, up 50 percent from 2021. Of those miles, 95 percent will be driven in self-driving, electric and shared vehicles and only 5 percent of those miles will be driven by internal combustion engine (ICE) vehicles.

The report goes on to say that autonomous EVs (A-EV) will make up 60 percent of the U.S vehicle stock, and those vehicles will be part of a shared-mobility service. As more people start to share cars, the overall number of vehicles on U.S. roads will drop from 247 million in 2020 to 44 million in 2030.

SEE ALSO: Going Autonomous: The Transformation of the Transportation Industry

The change is already happening. In 2016, shared-mobility companies such as Uber and Lyft drove 500,000 passengers per day in New York City, which is triple the number of passengers from 2015. Today, more and more automakers like Tesla and GM are also entering the shared-mobility market.

The findings illustrate a future where people drive more miles with fewer cars, which are fueled by electricity, and shared instead of owned. It’s a radical visualization of the future, but one that is driven by economic forces.

By 2021, shared vehicles will be 4 to 10 times cheaper per mile than private vehicles, and American households will save an average of USD 5600 every year by switching to shared EVs from cars fueled by gas, according to RethinkX.

Zoepf shared another report by ARK investment Management which echoes the finding above- in the next ten years, people will drive three times more kilometers using half the number of cars and the number of EVs on the road will increase 10 fold.

What It Means for Car Manufacturers and Suppliers

A shrinking vehicle fleet consisting of mostly EVs can only mean one thing: a major disruption to the current automotive market.  

Right now, the average lifecycle of a car in the U.S. is 11 years. However, the majority of a car’s total mileage is driven in its early years. It’s the same for shared vehicles, but they are driven about 80,000- 90,000 km per year, 10 times the distance of privately-owned cars. What this shows is a compression of the vehicle lifespan in its first 3 to 4 years.

These statistics pose critical concerns for automakers.

Will overall vehicle sales decrease in the coming future? According to Zoepf, that’s the wrong question to ask. Instead, automakers should be asking “will I make money?” Automakers have a couple of choices. They can either adapt early on and manufacture EVs and/or A-EVs at a competitive price, or become a shared-mobility provider. Early movers such as Tesla, GM and Volvo are already shifting their business strategies to fit these models.

Another question to ask is how these trends will affect vehicle design. With shortened vehicle life-cycles, manufacturers can either design cars to last only 3 to 4 years for quick replacements, or opt for the aviation model where the vehicle will be built to last, but the interior parts, such as seats, will be replaced frequently. Whatever route manufactures choose to take, gaining a competitive edge in vehicle and service quality early on will be key.

What Will This Mean for Vehicle Material Suppliers?

If building cars to last is no longer a primary priority, will car makers downgrade their materials? The short answer is not a chance.

Through a customer survey study Zoepf conducted of 60,000 Zipcar customers, he showed that the number one factor when choosing a car is safety. However, there is no one, ideal model or type of car that is preferred in a shared mobility framework. The purpose of the trip determines the type of vehicle, and the success of a shared mobility service provider will depend on the variety of cars it can provide – all with competitive safety ratings.

The supplier’s role will be to continue providing high-quality materials that can boost the safety and cost competitiveness of future vehicles. Steel suppliers have to keep developing lightweight and high-strength steels like POSCO GIGA STEEL, and research new materials that can boost the competitiveness of EVs such as POSCO’s Hyper NO for motor cores, battery materials and POSCO ICT’s EV charging service and infrastructure.

There remain numerous challenges that lie ahead for a greener and safer future with EVs and A-EVs, and it might take longer than experts predict for lawmakers, corporations and consumers to all agree on an optimal mobility model. However, change is already underway and automakers and suppliers alike need to strategize and adapt early on to take advantage of the upcoming opportunities.

Biggest Challenges in Bridge Construction

The major challenges for building urban bridges are the availability of skilled labor, access to urban areas and environmental compatibility.

Building bridges in megacities with the current scarcity of skilled labor will require a massive recourse to prefabrication. In a few circumstances, prefabricated bridge units will be transported on water with tugs and barges, which will allow the use of heavy, large units. In most cases, prefabricated bridge units will be transported on the ground through congested urban roads, which will lead to the use of light, modular units.

The availability of deck assembly areas and the interference of construction operations with adjacent infrastructure are additional challenges that will govern the bridge design process. As such, incremental launching construction from aerial platforms will see new applications, especially when combined with on-site welding of field splices among modular bridge units. The welding of field splices will also allow for optimized segmentation of bridge units, diminish the cost of field splices, and will relax the fabrication tolerances of the units.

Size Determines Cost, Cost Determines Everything Else

When constructing a bridge for an urban area, the size of a bridge governs the construction process. in turn, the construction cost of a bridge determines the materials and technology. Technology includes labor and investment in special construction equipment. The quantities of structural materials for a bridge depend on the design loads of the bridge, the flexural and shear span of the bridge units, and the mechanical strength of the material.

Small and large-scale bridge projects are both necessary in megacities and demand will only increase in light of the newly emerging megacities all over the world. When looking at both the construction of new bridges and the maintenance of existing bridges, the number of small-scale projects will definitely be larger than the number of large-scale projects. The impact these construction projects will have on the mobility of people and goods within a megacity is massive.

Although one may assume large-scale bridge projects with a larger budget will allow for design optimization and the efficient use of high-grade steels, scale economies in competition with other megacities will govern the availability of construction materials and workforce. Eventually, the scarcity of structural materials will lead to the efficient, eco-friendly use of steel and concrete in large and small-scale bridge projects alike.

Prefabrication and Incremental Launching for Bridge Construction

It is true that small-scale bridge projects have smaller budgets for technology, which limit design optimization and construction mechanization and increase the labor demand. Therefore, small-scale bridges will most likely be procured as packages of multiple bridges to acquire scale economies and a more efficient use of materials with the optimized design of modular units.

On the other hand, large-scale bridge projects allow for massive investment in special construction equipment, which will facilitate the prefabrication of modular bridge units in smart, eco-friendly factories. It will also diminish the labor demand of site assembly and the need for complementary infrastructure in an urban environment, as well as enhance the quality and durability of the final product.

Thus, large-scale bridge projects will be designed for modularity and have prefabricated standardized units with asynchronous production lines. Parts of the bridge will likely have different cycle times, just-in-time delivery, and require minimal site operations. Overall, construction technology and risk management of the trans-disciplinary relationships of mechanized construction will dictate the design of large-scale bridge projects in megacities.

Small-scale bridge projects will take advantage of incremental launching technologies. Launched bridges minimize the interference between deck construction and the obstruction to overpass, and this is a major advantage for urban bridges designed to overpass congested infrastructure. Launched bridges do not require extra clearance to support the deck during construction, which simplifies connecting the bridge with existing roads and railways. Launched bridges do not require additional right-of-way as the deck is built behind the abutment and incrementally pushed into position. Additionally, the construction area is far from the infrastructure to overpass, which minimizes the risk for workers and the traveling public.

Materials For the Future Generation of Urban Bridges

Steel and concrete are the most common materials for bridges. In the field of steel bridges, high-grade steel will reduce the self-weight of bridge superstructures and the cost of piers and foundations. New composite systems and mechanized plate corrugation will increase the buckling capacity of unstiffened web panels and compression flanges to avoid the use of welded stiffeners.

In the field of prestressed concrete, new steels for rebar will offer higher strength and corrosion resistance to increase the durability and service life of the next generation of urban bridges. Post-tensioning materials are already extremely efficient, and the challenge will revolve around finding new duct systems and passivating materials to able to avoid the quality concerns raised by cement grouts.

Full-span precasting has been employed in thousands of spans of high-speed railway projects and in hundreds of spans of light-rail transit projects. Both steel and prestressed concrete bridges will be present in the mass transit systems of megacities, and both types of bridges are perfectly compatible with steel decks should high-grade steel turn out financially competitive over prestressed concrete in the megacity-oriented life cycle cost analysis.

Modern large-scale bridge projects are designed for 75 or 100-year service life in the USA. The use of renewable protective materials can easily meet this target in steel bridges, but the evolution of design loads and service conditions of urban bridges is hard to predict. Steel bridges offer a major advantage over prestressed-concrete bridges from this point of view, as they are more adaptable and can be modified, strengthened and adapted to new use conditions.

POSCO has held its annual community service tradition, the POSCO Global Volunteer Week, since 2010.  This year, from May 24 to 30, over 79,000 POSCO Group employees from 52 different countries, including Korea, Turkey, Vietnam and the U.S., rolled up their sleeves and got to work. Here’s a look at some of the highlights.

POSCO Group in Korea

In Korea, POSCO Group employees made home improvements for underprivileged neighborhoods, mentored local youth and had a blast painting wall murals.

In the nation’s capital of Seoul, POSCO employees cleaned up marine waste with the Clean Ocean Volunteer Group, and another group delivered freshly baked bread to the community’s elderly.

On May 30, POSCO CEO Kwon Ohjoon and over 30 employees visited Myeongryundang of Sungkyunkwan Munmyo (a Confucian shrine), to repair and replace Korean traditional paper called Changhoji on windows and doors.

In the city of Pohang, POSCO’s volunteer groups visited Sangdo Middle School to conduct first aid and CPR training. Other volunteer groups in Gwangyang, another city in Korea where POSCO conducts business, launched a lunchbox delivery business to create jobs for the elderly and held classes for women for minority communities.

POSCO Group Across the Globe

POSCO subsidiaries in Turkey, Vietnam and the U.S., also took part in Global Volunteer Week.

In Turkey, POSCO ASSAN TST employees opened a Korean culture school for local elementary school students in March. During Global Volunteer Week, Students got to try on traditional Korean clothing called hanbok and volunteers built a playground made out of recycled tires for the kindergarten students.   

POSCO-Vietnam carried out activities to improve the environment of the POSCO steel village and installed safety bars in the POSCO steel bridge. POSCO-VST employees visited local orphanages to deliver healthy meals and deftly handled some exterior painting.

In the U.S., employees at POSCO-America gathered to clean up Centennial Olympic Park. The Detroit office went to the local food bank to distribute food to underprivileged neighborhoods and the Houston office cleaned up the memorial parks in the neighborhood to contribute to their respective local communities.

As one of the world’s leading steelmakers, POSCO will continue its efforts to contribute to global sustainable development by not only developing eco-friendly technologies but also giving back to local communities.

The tradition began when a Parsi banker wanted to have home cooked food regularly delivered to his office and gave the responsibility to the first ever dabbawala. It soon caught on among others and the demand for the meals-on-wheels service soared. 

Steel, the Preferred Metal for Your Meal

While the wala, or carrier, is no doubt the driving force behind the system, the dabba, or lunchbox, is a central component of India’s meal delivery culture. Widely used throughout the subcontinent, these multi-tiered “tiffin” (Indian English for a light midday meal) carriers are generally made from stainless steel and can keep food warm for up to three hours.

In addition to the tiffin boxes’ warming properties, the fact that they are made of steel means they offer plenty of other benefits, too. For one, they don’t leach toxins like plastic, ensuring food is safer, and they’re also more hygienic and easier to clean than those made of other materials—a big plus when it comes to rinsing off curry, vegetable and dal residue. Furthermore, the containers are durable and sustainable, meaning they don’t damage easily and can virtually last a lifetime.

Similar types of lunchboxes are also commonly used in other parts of the world, such as Southwest Asia and Northeast Africa, as well as parts of South America and Europe. Like India, the boxes in these containers hold much more than just food. They often contain mementos—a flower, a movie ticket, an apology note—and more importantly, love from the cooks, who are usually hardworking housewives. But the journey these steel boxes must undergo is a lengthy one—one that takes a dabbawala an entire day to complete. 

A Day in the Life of the Dabbawala

By 9 o’clock every morning, the dabbawala has hit the streets, pedaling his bicycle—one designed with extra iron to withstand a heavier load—through the congested Mumbai traffic to his assigned area. As many older buildings are not equipped with elevators, the dabba climbs up and down the towering residences to collect the tiffin boxes from homes.

By the time he completes the collection, it’s already about 10:30am. He now carries the 30-40 lunchboxes he has accumulated on his bike, undeterred by the poor road conditions, mud, traffic and merciless Mumbai monsoons that plague the region every summer.

He then reaches the nearest railway station where fellow dabbawalas gather and sort the tiffins by destination utilizing a simple but seemingly flawless coding system. By now, most of his tiffins are handed over to other teams dispersing to various parts of the city. He joins one of them, and with his teammates, transfers different tiffin boxes in crates and hastily transports them to the railway platforms on his head.

If a tiffin is on a complex route, it is further sorted on the railway platform where even more dabbawala teams work together to move the wooden crates into the trains. With the boxes put away in the luggage compartments, the men can take a short break before arriving at their assigned stations around noon.

Racing against the clock, the wala rushes out of the station with the lunchboxes atop his head and once again disperses them among other teams. Joining yet a different group, he and the men place the boxes in trollies and dash toward the business centers, the final destinations for the tiffin boxes.

As they do, pedestrians make way for the shouting, pushing dabbawalas, knowing well that they don’t stop for anyone. Each man then takes the responsibility of delivering the lunches to separate buildings, moving up and down the elevators. By 1pm, all are delivered, but the dabbawala’s job is not over yet. After a brief lunch, the dabbawala takes the empty tiffin boxes from the offices and repeats the process until all of the dabbas are returned to their respected homes before 6pm.

The century-old Indian meal delivery system that is powered by teamwork and steel remains incredibly efficient, even in an age where just about everything else is operated using the latest technology. Time will only tell how the process may evolve in the future (registration has recently gone virtual), but it is certain it will continue to serve as a model of service excellence for the entire world.
