Arup have released a new image of the proposed copper-nickel alloy cladding that will adorn Heatherwick Studio’s Garden Bridge in London. According to a report by the Architects’ Journal, the “concrete structure will be coated in ‘cupro-nickel‘, from its feet on the riverbed up to the base of the balustrades on the bridge deck.” The copper will be donated from Glencore, a multi-national mining company, forming ”a protective skin to the carbon steel structure giving it a maintenance free 120-year life, protecting the bridge from river and environmental corrosion.” More than 240 tonnes of the metal alloy, which often finds use in medical equipment and ship propellers, will be used.
According to a document published last month, London’s aspiration to become “a great cycling city” has taken one step closer to reality. The office of the Mayor of London has approved plans to develop Europe’s longest segregated bicycle lane through the centre of the city following modifications to an original plan that drew sharp criticism from residents and commuters. The new plans, which have been supported by a number of private companies and public bodies, aims to maintain vehicular traffic capacity whilst allowing the segregated cycle lanes to cater for a large capacity of cyclists.
With structurally unsound bridges, unsafe dams, and derelict roads becoming increasingly common problems, infrastructure has been brought to the forefront of many political agendas. However, limited funding in this area brings to mind the question of economics: how will improvements to North America’s major trading channels be made without driving the nation further into debt? This is what Jordan Golson addresses in the article, It’s Time to Fix America’s Infrastructure. Here’s Where to Start. Although not all of these infrastructural problems can be resolved in the foreseeable future, according to Golson, however some smaller improvements in the next few years can be a manageable starting point.

The Metropolitan Redevelopment Authority of Perth has released conceptual images for what is to become the city’s latest public space, designed by a team comprised of Aspect Studios, Iredale Pedersen Hook, and Lyons Architecture. With construction to begin in mid-2015 and slated for completion in 2017, the square takes its name from Yagan, an Indigenous Australian warrior of Perth’s local Noongar people. Integral to early resistance against British colonization, Yagan’s tenacity, leadership, and subsequent execution by settlers have cemented his role in Indigenous Australian folklore.

Crossrail, “the largest infrastructure project in Europe (costing more than the 2012 London Olympics) has been slowly winding it’s way beneath London‘s streets for years. Now, as the tunneling efforts begin to draw to a close, Crossrail have released a series of fascinating photographs demonstrating just how complex this latest London subterranean labyrinth is. There are currently more than 10,000 people working directly on Crossrail at around forty separate construction sites, who have now completed 90% of the total tunneling. This brings the entire project to two thirds of the way there.

The following is an excerpt from Keller Easterling’s latest publication, Extrastatecraft: The Power of Infrastructure Space, which explores areas of infrastructure with the greatest impact on our world. Easterling is a professor at Yale School of Architecture.
The road between Nairobi and Mombasa is lined with, and virtually lit by, advertisements for the mobile phone companies that have entered the region—all promising new freedoms and economic opportunities. With their images of Masai tribesman in native dress phoning from a remote wilderness, the ads employ an essential trope of leap-frogging—the desire for a perfect collapse between technology and nature, tradition and modernity. The billboards express the enthusiasm of a world turned upside down in which not the developed but the developing world has their hands around a majority of the world’s cell phones.
Over the last 150 years, the ocean floor has been laid with thousands of miles of submarine cable of all types for telegraph, telephone, and fiber-optic infrastructure. In the nineteenth century, it took only thirty years for the British cable-laying companies to string the world with telegraph cable, and a little over a decade from the late 1980s to the late 1990s for most of the world to be connected to fiber-optic cable. Yet until recently, East Africa, one of the most populous areas of the world, had no fiber- optic submarine cable link and less than 1 percent of the world’s broadband capacity. A country like Kenya had to rely for its broadband on expensive satellite technology acquired in the 1970s that cost twenty to forty times its equivalent in the developed world. Before 2009, one Mbps (megabit per second) of bandwidth could cost as much as 7,500 US dollars per month against the world average of $200. The monthly cost of putting twenty-five agents on the phone was $17,000 a month instead of the $600–900 that it would cost in other developed countries.(1)
After a fortnight of highs and lows for Thomas Heatherwick and British celebrity Joanna Lumley’s campaign for a garden bridge stretching across London’s River Thames, Rowan Moore of The Observer has meticulously described the project as “nothing but a wasteful blight.” Although he acknowledges that support for the bridge “has been overwhelming,” he argues that Heatherwick – though an “inventive and talented product designer” – has a past record in large scale design which “raises reasonable doubts about whether his bridge will be everything now promised.”
CEMEX has unveiled the international finalists for the XXIII Building Awards, which aim to recognize the best architecture and construction internationally. Spanning across three categories, the awards recognize housing, institutional/industrial and large-scale infrastructure projects that were built during 2013 and stand out for their constructive solutions, aesthetics and innovative techniques.
Both the international and national winners will be announced on November 5. Read on after the break for the international finalists and check out our coverage on the Mexican finalists for the XXIII Building Awards here.
Despite Finland’s relatively cool temperatures, climate changes have made heat waves more common in Northern Europe, and the demand for cooling buildings in summer is increasing. Instead of installing air conditioners for individual buildings, Helsinki is pioneering a vast network of underground infrastructure that pumps cold water from lakes and seas into local buildings. Beneath an unassuming park in downtown Helsinki sits a reservoir containing nearly 9 million gallons of water that is recycled and cooled by waste energy after it is used for cooling, replacing the need for air conditioning in the city and cutting carbon pollution by 80%. Read more about this undertaking in this article from Fast Co. Exist.
“Nearly half of London’s population lives east of Tower Bridge yet they are served by only two fixed road river crossings,” says Colin Stanbridge, Chief Executive of London Chamber of Commerce and Industry (LCCI). This is the infrastructural predicament which has sparked the LCCI’s “Bridge East London” campaign, a proposal for bridge linking Beckton and Thamesmead at Gallions Reach, which is aided by a design by HOK.
The proposal was unveiled on Monday, the 120th anniversary of the opening of Tower Bridge. Designed to allow clear passage for both ships underneath and aircraft taking off or landing at City Airport above, the bridge also features a segregated cycle path, adding a much needed - and entirely safe – river crossing for London’s growing number of cyclists.

The Moscow Metropolitan is the second busiest metro line in the world, transporting 2.4 billion passengers a year. However despite this, it is a long way short of being the most extensive, with Beijing, Shanghai, London, New York, Tokyo, and Madrid all surpassing it in terms of total track length.
In order to rectify this, in 2012 Moscow launched an ambitious expansion plan, aiming to add over 150km of tracks and 70 new stations by 2020. For the first time, they have launched a competition to design two of these new stations in the South-West of the city, in the Solntsevo and Novo-Peredelkino Districts.

The construction of Hudson Yards, the biggest private real estate development in the history of the United States and currently the largest development in New York City since the Rockefeller Center, is gaining momentum. The vast infrastructural project in the heart of the city is set to enclose an active rail yard with an expansive platform, paving the way for 28 acres (and 17 million square feet) of commercial and residential space. Housing over 100 commercial units, 5000 residences, 14 acres of open public space, an enormous school and luxury hotel all on top of a working train depot, the project will directly connect to a new subway station and meet with the High Line.
First-Place Winner of Santiago Landmark Competition: Smiljan Radic + Gabriela Medrano + Ricardo Serpell
Smiljan Radic, Gabriela Medrano, and Ricardo Serpell have won a competition to design a new landmark for Santiago, Chile: an antenna tower to be placed on the summit of San Cristobal Hill, in the heart of the city. The “Santiago Antenna Tower,” a unique telecommunications tower with panoramic views, should be completed in 2017, in time for the centenary of the Metropolitan Park of Santiago.

We architects know full well the power of renderings to capture the imagination. Apparently – so too do politicians. Capitalizing on the popularity of adaptive reuse projects around the world (a trend instigated by the success of New York’s High Line), French politician Nathalie Kosciusko-Morizet has made converting Paris’ unused “ghost stations” a major part of her platform, promising that these projects will come to pass should she be elected mayor.
The renderings, by Manal Rachdi OXO Architects and Nicolas Laisné Associés, show the Arsenal station (unused since 1939) alternately as a swimming pool, a green park, restaurant, disco, or theater. As there are in fact 16 disused metro stations in Paris, the idea behind these renderings is to instigate debate among practitioners as to how these spaces could best serve the city. See all the renderings, after the break.
Writing for Future Cape Town, this article by Julia Thayne – originally titled The Skycycle: A Plan for the People? - explores the proposal by Foster + Partners to build an elevated cycle highway above London’s, explaining why it is little more than an optimistic pipe-dream.
Headlines in London this November were grim. Six cyclist deaths in less than a fortnight. All but one cyclist killed in accidents involving trucks, buses, or coaches. People were understandably concerned. From 3,000 miles away, my mother sent me a fluorescent coat and another set of bike lights, and as a cyclist commuter, I avoided roundabouts that I had previously sailed through, noting that cars seemed to be driving more slowly and other cyclists thinking twice before flouting traffic laws.
In response to the deaths, the public and public sector alike launched a “cycling state of emergency.” Officers patrolled the streets to ticket both vehicles driving unsafely and cyclists disobeying road rules. A thousand citizens gathered for a candlelight vigil at the roundabout where three cyclists’ lives had been claimed. Another thousand staged a “die-in” outside of Transport for London’s headquarters, in which protesters lay down in the streets, using their bicycles to block traffic. Newspaper columns, magazine articles, and blog spots examined and re-examined the safety of cycling routes around London. Mayor Boris Johnson’s Cycle Superhighways (four blue-painted, supposedly safety-enhanced cycling routes around London) became a particularly contentious topic of discussion, as three of the six cyclist deaths during those two weeks (and of the 14 deaths thus far in 2013) had occurred on or near one of these routes.
From the conversation about cycling and safety, the Skycycle has emerged.

The AIA has given the 25 year award - for architectural projects which have stood the test of time – to the Washington DC Metro System. Designed by Harry Weese and opened in 1976, the metro system has been praised for its application of a sense of civic dignity to the function of transportation, as well as the consistency of the design across its 86 stations. You can read an accompanying article about the design of the Metro System here.
Located in Doha, Sharq Crossing is a set of three interconnected bridges spanning almost ten kilometres in the Doha Bay. Designed by the famed architect Santiago Calatrava, the bridge will connect the city’s cultural district in the north to Hamad International Airport and the central business district in West Bay. The bridges, which are designed to accomodate as many as 2,000 vehicles an hour per lane, are also flanked by a series of subsea tunnels to manage and direct the flow of traffic across the bay.
OMA has won an international competition to design Pont Jean-Jacques Bosc, a bridge across the river Garonne in Bordeaux, France, that will link the municipalities of Bègles and Floriac. The 44m by 545m bridge, which will act as “a generous new public space” and “an urban planning intervention” for the city, giving priority to pedestrian traffic, is the first to be realized by OMA. It is scheduled for completion in 2018.
According to Clément Blanchet, director of OMA France, the bridge ”is not the ‘event’ in the city, but a platform that can accommodate events of the city [...it] may be the least technical, least lyrical, but [it is] the most concise and effective structural solution.”
