Airports in China Hew to an Unswerving Flight Path

New arrivals are whisked on electronic walkways through a bright, spacious airport terminal that features elegant lounges, free Wi-Fi, speedy security checks and an efficient baggage handling system.

This is what the best airports now look like in the world’s second-largest economy.

Three years after it opened, Terminal 2 at Hongqiao International Airport in Shanghai stands as a testament to China’s economic ambitions, and to its unique approach to infrastructure development.

With extraordinary government support, Shanghai built a massive airport terminal in 32 months as part of a $9 billion transportation hub that connects the air terminal with the city’s buses, subway platforms and a new high-speed railway network.

“They know how to build things and how to do it efficiently,” said Jeffrey N. Thomas, chief executive of Landrum & Brown, an American firm that helped design the new Shanghai terminal. “That area went from plans on a piece of paper to a complex that has 14 million square feet in less than four years. That’s hard to do.”

At a time when many American airports are falling into disrepair, China is quickening its air travel development, with plans to build nearly 100 more airports by 2015, including some at high altitudes, where special landing gear is required. Many of those airports are expected to lose money, but that hasn’t deterred the government, which views the expansion of infrastructure as vital to economic development.

China’s big-city airports are already colossal. Last year, Beijing Capital International Airport handled 81 million passengers, up from 27 million in 2002.

This year, it could surpass Atlanta’s Hartsfield-Jackson International Airport to become the world’s busiest.

In Shanghai, Pudong Airport — which operates 25 miles east of Hongqiao as the city’s international gateway — has so many flights it plans to add a fourth and fifth runway, something few other airports in the world possess.

The quality and speed with which China builds its big city airports is impressive. But whether China holds any lessons for airport development in America, or Europe for that matter, is unclear, analysts say.

China’s building programs are supported by an authoritarian political system that brooks no challenges. When the government decides to build or expand an airport, there are no public hearings or any public protests of note.

And while economists ponder the long-term consequences of that decision-making process, this country’s leaders push ahead with new megaprojects.

“There’s a pro-investment bias here, partly because the country still has so much surplus labor, which makes it a lot cheaper to build,” said Louis Kuijs, an economist at the Royal Bank of Scotland based in Hong Kong. “And this is a country that knows how to build. Look at the Great Wall!”

Terminal 2 at Hongqiao Airport is one of those “this could only happen in China” developments. With Terminal 1 congested, the city announced plans in 2006 for a new transportation hub to cover 10 square miles, a project that when complete is likely to be the world’s largest transit hub with about 1.1 million passengers a day.

To build it, the city cleared 10,000 residents from a huge plot of land west of Hongqiao by building new apartments for them a few miles away. Because the state owns all land in China, and residents have little bargaining power, local governments and developers often benefit from lower development costs.

And in the case of the transportation hub, once the land was cleared, state-run banks lined up to lend money to the project.

“The relocation and acquiring of land this size, only China can do it,” said Cao Longjin, general manager of Shanghai Rainbow Investments, a state-run company that helped develop the hub. “It’s a miracle.”

When China went on an earlier airport-building spree in the 1980s and early 1990s, things didn’t go quite so smoothly. The airports tended to be poorly designed and minimally functional, and usually lost money.

Now, big cities are flush with cash from a real estate boom. Government officials take part in overseas fact-finding missions, hire international consultants and set up joint ventures that improve the chances that the biggest airports will turn a profit.

In Shanghai, the city’s airport authority helped set up Shanghai Rainbow Investments to develop the new transportation hub and revitalize the area around it. The plan includes a new central business district with towers, five-star hotels and a vast mixed-use commercial project created by the Hong Kong developer Shui On Land. The developer hired the American architect Ben Wood, who designed Shanghai’s popular Xintiandi commercial and entertainment district.

City officials also designed Terminal 2 with profit-making ventures in mind, modeled on airports in London, Hong Kong and Singapore, where terminals double as vibrant shopping malls, packed with duty-free shopping and restaurants.

“We looked at what areas of an airport are profitable and which are typically not profitable,” said Liu Wujun, chief technical officer at the Shanghai Airport Authority and one of the main planners behind Terminal 2. “The areas that tend to be profitable we made as large as possible; the areas not so profitable we made as small as possible.”

The result was smaller roadways alongside the airport (not so profitable), and larger hotels, retail outlets and cargo-processing sections (more profitable).

Atlanta’s airport is one of the world’s most cost competitive, with about 70 percent of its revenue from nonaviation areas like shops and parking. That is Shanghai’s model, Mr. Liu said.

Part of the profitability equation involved lowering the cost of construction. And experts say that comes easier in China, where aggressive building schedules are the norm.

Shanghai, for instance, hired more than 13,000 construction workers to develop the transportation hub and did what many projects here do: it instituted a 24/7 construction schedule. Commuting time was minimal since most of the workers lived on site.

So while Heathrow Airport Terminal 5 in London took nearly six years to build and cost $6.5 billion, Hongqiao’s Terminal 2, roughly the same size, was built in less than half the time for a third of the cost. When it opened in early 2010, Terminal 2 had 80 check-in counters and capacity to handle 300,000 flights a year. Last year, the airport handled 234,000 flights.

Inside, Terminal 2 was also fitted with Starbucks coffee, Armani, Zegna, Hermès and Bulgari stores, a duty-free shopping area and office space for lease. Outside the terminal, a shopping mall that connects the railway station with the airport terminal has been slow to develop. But the government says the terminal is profitable.

With more than 30 million passengers expected to pass through its halls this year, billboard advertising comes at a premium.

But rather than sign a deal to lease out the billboards, the city’s airport authority brokered a potentially more lucrative deal in 2005 by forming a joint venture with JCDecaux, the French outdoor advertising giant, one that gives the airport a majority stake.

An executive at JCDecaux China says the company helped the airport authority plan Terminal 2 with oversize indoor and outdoor advertising displays in mind. Rates in Shanghai, the spokesman said, can be as high as $2 million a year, in some cases higher than rates in the United States or Europe.

Chinese airports have other financing advantages over the United States, like higher landing fees for airlines and mandatory airport construction fees paid by passengers, as much as $13 a flight.

A 1973 law prohibiting airports in the United States from charging passenger fees was changed in 1990. In 2000, the fee was raised to $4.50 a flight, about half as much as China’s fee, though airfares are higher in the United States.

In the United States, there are warnings that the poor state of infrastructure at American airports is likely to hold back the industry, and that one of the impediments is the way government restricts financing options.

“We’re going to have to change the way our airports are regulated in terms of how they finance things and how they put projects in place,” said Greg Principato, president of the Airports Council International North America, which represents the nation’s roughly 450 commercial airports.

Of course, with expansion China’s airports will face tough management challenges, particularly if labor costs rise and air traffic slows. There are also concerns among some analysts who study economic development that China’s airport program is excessive and that the country’s high-speed rail is likely to erode the profitability of airports.

But Mr. Liu, the chief technical officer at Shanghai’s airport authority, jokes about how much more profit-oriented state-owned operators are in China. “The difference between here and the U.S. is that in the U.S., the government manages the nonprofit parts of an airport and gives the profitable parts to the private sector,” he said, laughing. “The U.S. way is more socialist and the Chinese more capitalist.”

Ondas inmateriales, pabellón de SANAA en el Vitra Campus


03 de mayo 2013

Para sustituir un antiguo pabellón de producción y en línea con la estrategia de la firma suiza Vitra de confíar el diseño de sus edificios a los arquitectos más prestigiosos del mundo, los japoneses de SANAA han levantado, dentro del Vitra Campus —el complejo de la compañía en la localidad alemana de Weil am Rhein, cerca de Basilea—, un edificio circular de 20.000 metros cuadrados de superficie, con un diámetro de más de 160 metros y casi 12 de altura. Adaptándose a las necesidades de amplitud y flexibilidad espacial, la forma en círculo imperfecto, en contraposición a los volúmenes ortogonales del resto del campus, supone la reducción, optimización y organización de los flujos de transporte dentro del pabellón, destinado al diseño de tiendas de la marca. La envolvente se compone de una capa exterior, transparente e incolora, y otra interior, opaca y blanca; a través de un complejo proceso se consigue una sucesión irregular de ondas en los paneles fundidos, reforzando el carácter inmaterial del edificio. Hileras rítmicas de huecos en la cubierta y aperturas aisladas en la fachada iluminan el interior.

Foster + Partners inaugura nuevo aeropuerto sustentable en Jordania

 24 Marzo 2013


Con sede en Londres, la oficina Foster + Partners celebró hace algunos días la inauguración de un nuevo terminal para el aeropuerto Queen Alia, ubicado al sur de Amman, en Jordania. El edificio modular, que está cubierto con pequeñas cúpulas de hormigón, se inspira en el diseño tradicional islámico para crear un espacio único que utiliza tecnologías pasivas para mantener una temperatura constante frente a los drásticos cambios climáticos de la región.

Más información e imágenes, después del salto.

Además de crear una estructura visualmente impactante y eficiente, Foster + Partners ha incorporado espacios verdes al aire libre para ayudar a purificar el aire y compensar las emisiones de tráfico del aeropuerto. La tradición fue parte integral del diseño de la terminal del aeropuerto. Tras señalar que “Amman es una de las ciudades habitadas más antiguas del mundo”, los arquitectos se inspiraron en ella para crear las cúpulas teseladas que conforman la estructura de la cubierta, haciendo eco de la “tela negra, que fluye” de una tienda de campaña beduina tradicional.

La parte inferior de las cúpulas cuenta con diseños islámicos grabados tomados de las venas de una hoja, formando lágrimas de tragaluces ubicadas entre las cúpulas, inundando la explanada de la terminal con luz natural. El hormigón estructural visible desde el interior es mezclado con grava local para producir un color de arena que ayuda a crear una continuidad visual entre el vestíbulo del aeropuerto y el paisaje exterior.

Plazas exteriores sirven para propósitos ambientales, sociales y estéticos. Con dos alas, las puertas de salida se extienden a cada lado del edificio central. El patio en la entrada del edificio se extiende y se llena de árboles, generando zonas verdes y bancas para ofrecer a los viajeros con un espacio para saludar y despedirse de los seres queridos.

Edificio de Oficinas 255



Ganador en año 2009 del concurso para diseñar un edificio que produce más energía de lo que consume promovido por el Consejo Regional de Borgoña (Francia), este edificio de oficinas aspira a convertirse en él de mejor rendimiento energético del sector terciario de esta región. Se construyó con estructura de acero y forjado mixto suministrados por ArcelorMittal Distribution Solutions.

Situado en el nuevo parque empresarial de Parc Valmy, al norte de Dijon, el edificio de oficinas "255" de 3.400m2 se caracteriza por su escaso consumo de energía. Esto se ha conseguido gracias a la elección de los materiales de construcción, a la aplicación de tecnologías estándar de construcción, a primar la construcción de una estructura con una gran inercia, al aislamiento externo y al tratamiento de los puentes térmicos.

Una instalación de paneles fotovoltaicos en el cubierta, con una extensión de 450 m2, convierte el edificio 255 en un "edificio de energía positiva" con una sobreproducción de energía de 20. 000kWh/año.

Sin embargo, este edificio de concepción singular puede no ser una excepción. A pesar de que es un edificio técnicamente muy logrado, el "255" es un modelo que se puede reproducir con facilidad, con un coste similar a una construcción más clásica y con unos costes operativos menores a largo plazo.

SETUREC y otras empresas que ocupan este edificio participan en la reducción del consumo de energía en el sector terciario y por lo tanto van 12 años por delante de las obligaciones legales establecidas en la ley Grenelle II. El objetivo de la legislación francesa con Grenelle del Medio Ambiente I y II es el de fomentar y promover un urbanismo económico que sea consecuente con el espacio y con los recursos energéticos. Establece que desde comienzos del año 2012, todo edificio nuevo de Francia debe tener la clasificación de edificio de bajo consumo energético (con un consumo máximo de 50 kWh/m2). Desde el año 2020 en adelante, toda nueva construcción debe tener un balance energético positivo.

255 – ¿Un edificio de consumo energético bajo, pasivo o incluso con balance positivo?

En teoría el edificio 255 cumple los criterios de edificación con balance energético positivo.

Gracias a su instalación fotovoltaica y a su aerogenerador, el edificio producirá anualmente un 12% más de energía de la que en realidad consume. En los próximos años se aplicarán una serie de medidas con el fin de evaluar el consumo real de energía y en caso de que sea necesario se adoptarán ciertos parámetros con el fin de mantener la clasificación de edificio con un excedente real de energía.

Principios técnicos de la construcción del 255:

- una fuerte inercia: el objetivo es almacenar el aire caliente o frío gracias a la propia masa del edificio (suelos, paredes ..)
- tratamiento de los puentes térmicos: minimización de las fugas de calor provocadas por defectos en la resistencia térmica en el ensamblaje de 2 materiales diferentes de aislamiento
- la estanqueidad del aire es un requisito importantísimo en un edificio pasivo; el objetivo es crear un edificio totalmente hermético
- la calefacción con aglomerado de madera (pellets), sistemas de ventilación de doble flujo y pozos hidráulicos, entre otras medidas, aseguran el mantenimiento de la temperatura dentro del edificio en invierno y la refrigeración en verano.
- iluminación y equipamiento general: el sistema de iluminación se basa en detectores de movimiento, la iluminación varía en función de la intensidad de luz natural, incorpora la protección solar, recupera el agua de lluvia para uso doméstico, etc.

¿Por qué 255?


Según se dice, los números se le ocurrieron por casualidad al arquitecto en el momento de concebir el edificio. Finalmente, cuando se elaboró el boceto, en la fase de diseño los tres números se hicieron visibles para todo el mundo en los tres miradores blancos que, de alguna manera, sobresalen y resaltan con la fachada de ladrillo rojo.

Su destino quedó sellado definitivamente cuando se recibió el permiso de construcción y hubo que dar al edificio un nombre oficial.

Grandes espacios, luminarias, grandes ventanas y paneles de vidrio en el suelo permiten que la luz y el calor entren en el edificio. Con su fachade de colores cálidos el edificio 255 realmente fue concebido como un espacio para un modesto consumo energético y sin embargo es un edificio moderno, cómodo y acogedor.

El enfoque global no solo concierne al edificio en sí mismo, sino que también tiene como objetivo la concienciación de sus ocupantes respecto a aspectos medioambientales y al ahorro de energía. Por ejemplo, se les invita a utilizar el transporte público ya que el Parc Valmy está conectado a la red de tranvías desde diciembre de 2012.

Zaha Hadid appointed to develop plans for new London airport

22 febrero 2013


News: Zaha Hadid Architects has been appointed by the Mayor of London to help develop plans for a major new airport in the southeast of England.

Hadid's firm will work alongside UK-based engineers Atkins and Pascall+Watson, the architects who designed Terminal 5 at Heathrow airport, to prepare a submission to the UK government about the future of aviation around the capital.

"This work is essential to deliver the most integrated transport solutions for London and the UK," said Hadid. "It will enable London to maintain its position as one of the world's most important economic, commercial and cultural centres, outlining the city's future growth and development, which has always been founded on global connectivity."

The Mayor of London, Boris Johnson, said: "It is absolutely imperative that work to progress a new hub airport in the southeast is completed as soon as possible. The government has set a timetable that dawdles, when dash should be the order of the day.

"That is why I have assembled a mighty team of experts who I have tasked with delivering a fulsome examination of the most realistic solutions to our aviation crisis in the shortest time possible, which I look forward to sharing with the government."

In 2011, architect Norman Foster unveiled his own proposals for an airport and transport hub on the Thames estuary, while last year architects Gensler proposed a floating airport connected by underwater tunnels for the same location – see all airports.

Earlier this week Hadid slammed the UK's "misogynist" attitude towards women architects after a survey found nearly a third knew they were paid less than their male counterparts – see all news about Zaha Hadid.

Top image shows Hadid's proposal for an extension to Zagreb Airport in Croatia.

Here's the full press release:

--------------------------------------------------------------------------------

Mayor announces world-class team to develop hub airport plans

The Mayor of London has appointed a world-class team of experts to help develop plans for a multi runway hub airport in the southeast.
 Today (11 February) the Mayor will also give oral evidence to an aviation inquiry convened by the Parliamentary Transport Select Committee. Committee members are expected to ask him why developing a new hub airport is so important to London and to explain why further expansion of Heathrow is impossible.

Appointing a world-class team of experts has added further weight to the work being driven forward by the Mayor to address the nation’s aviation crisis. He has made it very clear that he wishes to see the speediest possible resolution to the debate on where to build a multi runway hub airport, so that the British economy is given the best chance to prosper in the face of huge competition from its global rivals
 The Mayor has confirmed that the following organisations have all been engaged to help with work being prepared for submission to the Government.

They will provide expertise under the following themes:

Airport design & infrastructure

Atkins - one of the world’s leading design, engineering and project management consultancies. Projects they have worked on include the London 2012 Olympics, Bahrain World Trade Centre and the Dubai Metro. Atkins will also lead on consideration of surface access and environmental impacts.

Zaha Hadid Architects – Zaha Hadid was awarded the Pritzker Architecture Prize (considered to be the Nobel Prize of architecture) in 2004 and is internationally renowned for her theoretical and academic work. Time Magazine included her in their 2010 list of the 100 most influential people in the world. She has worked on globally celebrated projects such as the London 2012 Aquatics Centre and Guangzhou Opera House in China.

Pascall & Watson architects - Previous projects include Heathrow Terminal 5, Dublin Airport Terminal 2, Rome Fiumicino Airport Masterplan. They also designed St Pancras International Station.

Socio economic impacts

Ramboll – a leading international engineering and management consultancy with a track record of examining the economic impact of airports and other infrastructure from around the world, supporting key developments in European air traffic control, working on the new Thames Crossing and developing National Policy Statements.

Oxford Economics – a world leader in global forecasting and quantitative analysis for business and government with unrivalled experience of exploring the economic impact of the aviation sector and airports for clients including IATA, ATAG, BAA and Airbus and developing economic forecasts and scenarios for London.

York Aviation – a leading firm specialising in the assessment of the economic impacts of aviation and aviation demand planning.

Professor Peter Tyler - Peter is a Professor in urban and regional economics in the Department of Land Economy, University of Cambridge and Fellow at St. Catharine's College. Peter has an extensive track record in undertaking research for the public and private sector and an established reputation in the field of urban and regional economics with a particular emphasis on the evaluation of policy. He has been a Project Director for over seventy major research projects for Government.

Commercial viability

Ernst and Young – a global leader in assurance, tax, transactions and advisory services.

Legal and regulatory

Ashurst – The leading global law firm, which specialises in advising corporates, financial institutions and governments. Their core businesses are in corporate, finance, energy, resources and infrastructure.

The Mayor of London, Boris Johnson, said: "It is absolutely imperative that work to progress a new hub airport in the southeast is completed as soon as possible. The Government has set a timetable that dawdles when dash should be the order of the day. That is why I have assembled a mighty team of experts who I have tasked with delivering a fulsome examination of the most realistic solutions to our aviation crisis in the shortest time possible, which I look forward to sharing with the Government."

Zaha Hadid said: "This work is essential to deliver the most integrated transport solutions for London and the UK. It will enable London to maintain its position as one of the world's most important economic, commercial and cultural centres; outlining the city's future growth and development which has always been founded on global connectivity."

Mike Pearson, UK director of airports, Atkins said: "This project is not purely about the creation of a new hub airport, it's about forming the foundations for London's future development and reaffirming the UK's position as a key international centre. It will fundamentally shift the debate on UK aviation once and for all, providing both a convincing and compelling case for how international air connectivity is critical to underpinning the UK economy, as well as driving wider regeneration."

Around 15 different proposals for a new hub airport in the southeast have already been made public. The Mayor has consulted on criteria that will be used to evaluate each of those proposals and to form a shortlist of options. That shortlist is expected to be announced within weeks and the team now assembled by the Mayor will combine their expertise to produce detailed feasibility studies of the shortlisted options that the Mayor will submit to the Davies Commission.
