Remnant Infrastructure

In an interestingly archaeological story from the world of digital infrastructure, engineers who discovered "an unused fibre optic cable in Mongolia" were able, after putting it back into service, to "shave milliseconds" from a British firm's internet traffic between London and Hong Kong. After all, there is "unused cabling infrastructure around the world," like forgotten limbs awaiting future reactivation.

"We're finding unused cables all time, everywhere [from] China and Russia to parts of Brazil," a manager named Scott Ritchie explains to Information Age. He continues:

Quite often, when electricity lines are put down, there's underlying optical fibre as well, because if you're digging a hole you may as well whack as many services in there as possible. Some of these assets have been decommissioned or just forgotten about after companies go bankrupt. And sometimes when military objectives change, all of a sudden a bunch of infrastructure becomes available.

And there are backstage geopolitics involved: "We found a cable that went from the Russian border directly down through Mongolia, which cuts out the Northern part of China," Ritchie explains. But, he asks, "Why would there be a secret substation on the Russian border? You would need to ask the Chinese government.'"

It's as if closed-door diplomacy and international espionage together work to leave spatial and infrastructural fossils: embedded fragments of obsolete, redundant, or otherwise forgottenperhaps only recently declassifiedsystems that no longer serve their original purpose.

So they're resurrected for business and finance, requiring astute forensic detective work to uncover: "Discovering cables like these is a matter of technical analysis and local market intelligence. 'We have a dedicated team of network engineers whose sole job is to improve the performance of our network,' explains Ritchie. 'A major element of that is discovering new network systems'"where "new," in this specific example, refers instead to the remote archaeological remains of cross-border espionage projects, old spies' wires brought back online for private telecommunicative purpose.

Imagine a modern descendent of Piranesi with a summer job for AT&T, sent off alone with a truck, a tent, and some wire-testing equipment to explore abandoned villages in the mountains, on the hunt for internets he must single-handedly reawaken.

Loop Geography as Defensive Tactic

BLDGBLOG 02/01/2012 18:37

In a fascinating detail from a long series of articles published two years ago in the Washington Post, recently expanded as a stand-alone book called Top Secret America, we learn about one way to hide classified government infrastructure in plain sight.

[Image: Photo by Michael S. Williamson, courtesy of The Washington Post].

"[J]ust outside Washington," authors Dana Priest and William Arkin explain, in the exurbs of depopulated office parks and "huge buildings with row after row of opaque, blast-resistant windows," there can be found what the authors describe as "the capital of an alternative geography of the United States, one defined by the concentration of top-secret government organizations and the companies that do work for them."

One such complex, called Fort Meade, "is the largest of a dozen such clusters across the United States."

And it is cleverly camouflaged:

The existence of these clusters is so little known that most people don't realize when they're nearing the epicenter of Fort Meade's, even when the GPS on their car dashboard suddenly begins giving incorrect directions, trapping the driver in a series of U-turns, because the government is jamming all nearby signals.

It's an experiential trap streetan infinite loopa deliberate cartographic error introduced into the mapping of the world so as to sow detour and digression. A kind of digital baffling, or recursive geography as state defensive tactic.

I'm also curious when we might see this privatized and domesticatedgated communities, for instance, blocking the GPS navigation of their streets in the misguided belief that this will help protect them from future burglary, effectively delisting themselves from public cartographic records. Perhaps the future of neighborhood security lies in the privatized repurposing of advanced signal-jamming technology, the misleading lamination of other, false maps onto the streets as they really exist.

The Baffler

[Image: From "Baffles and Bastions: The Universal Features of Fortifications" by Lawrence H. Keeley, Marisa Fontana, and Russell Quick, courtesy of the Journal of Archaeological Research (5 March 2007)].

In a paper called "Baffles and Bastions," published in the Journal of Archaeological Research, anthropologists Lawrence H. Keeley, Marisa Fontana, and Russell Quick offer a detailed history of militarized building design features such as "V-sectioned ditches, defended gates, and bastions."

All of the features they subsequently analyze occur at peripheries, borders, and thresholds. In their own words, "the militarily functional ditch and gate features and bastions discussed below, in fact and by definition, are all distinguished by being part of enceintes (that is, surrounding barriers or enclosures). Enceintes are barriers that prevent access to and, almost always, obscure vision of a particular location."

Their diagrams of "baffled" entryways, seen above, are particularly interestinga kind of archaeological variation on floor plan pornrevealing the various techniques used to at fortified points of entry to gain an advantage over invaders. Through a navigational encounter with architecture, attackers are forced to show their vulnerabilities. "Baffled gates force attackers who enter them to expose their flanks and rear to defenders fire," the authors write. "Ideally, they require attackers to turn left exposing their unshielded right side. Left-turning baffles also were useful against (typically) right-handed bowmen."

Bioluminescent Billboards

[Images: A "living neon sign" made of bioluminescent bacteria; via UC San Diego].

Scientists at UC San Diego have made a bioluminescent bacterial billboard. They call it a "living neon sign composed of millions of bacterial cells that periodically fluoresce in unison like blinking light bulbs." Making it all work "involved attaching a fluorescent protein to the biological clocks of the bacteria, synchronizing the clocks of the thousands of bacteria within a colony, then synchronizing thousands of the blinking bacterial colonies to glow on and off in unison."

These are referred to as biopixels.

Two summers ago, we looked at the idea of a "bioluminescent metropolis," where light-emitting organisms could be used to supplementor even replacea city's existing sources of illumination, as if scaling the Newnes Glow Worm Tunnel up to size of a whole city (something that might be useful for places where streetlights are being turned off and even physically removed because paying tax in support of public infrastructure is socialist).

In that post, one of my personal favorites here on the blog, we looked at the work of architect Liam Young, who once proposed the creation of bacterial billboards, squirrel-like living screens that would crawl through and inhabit the city. They would nest in trees like LED ornaments and spring up whenever there's news (or advertisements) to display.

[Image: Bioluminescent billboards by Liam Young].

So could this vision of a bioluminescent metropolis be far off? UC San Diego suggests that their "flashing bacterial signs are not only a visual display of how researchers in the new field of synthetic biology can engineer living cells like machines, but will likely lead to some real-life applications." Surely it would not take much workeven if only as a media stuntto make a full-scale functioning prototype of a bioluminescent streetlight? Or a bioluminescent bathroom nightlight for your kids?

But, then, of course, the inevitable escape from domestication, when invasive bioluminescent organisms, from genetically-modified kudzu and street weeds to super-bright worms and bacterial mats, conquer the city.

Ice Island Infrastructure

BLDGBLOG 31/12/2011 19:08

[Image: "From Seismic Arrays on Drifting Ice Floes: Experiences From Four Deployments in the Arctic Ocean" by C. Läderach and V. Schlindwein, from Seismological Research Letters].

In a paper published back in the July/August 2011 issue of Seismological Research Letters, authors C. Läderach and V. Schlindwein from the Alfred Wegener Institute for Polar and Marine Research discuss the benefits of tracking deepsea earthquakes using "seismic stations mounted on drifting ice floes." Indeed, they write, because of the lack of fixed ground points, "mounting conventional land seismometers on drifting sea ice is the only way to acquire seismic data in the Arctic Ocean."

In other words, they want to turn drifting fragments of Arctic sea ice into floating research stations, mapping earthquakes at sea.

[Images: "From Seismic Arrays on Drifting Ice Floes: Experiences From Four Deployments in the Arctic Ocean" by C. Läderach and V. Schlindwein, from Seismological Research Letters].

The authors have already seen considerable success with this method. In a short passage detailing how these systems are physically installed, we read that the seismic arrays "are deployed and recovered by helicopters operating from icebreaking vessels." However, "the time for station installation is very limited," due to weather and rough seas.

Station installation requires two people and a helping hand from the helicopter pilot, and takes about 30 minutes with the data loggers being programmed before the deployment flight. The limited time does not allow waiting for the sensor to equalize. Therefore, we only check the sensor response and locking of the GPS position before leaving the station.

While the authors compare this, briefly, to using buoysindicating that their method is not all that different from other free-floating oceanographic instrumentation systemsthe transformation of icebergs into scientifically useful platforms is a compelling example of how a natural phenomenon can become infrastructure with even the smallest addition of equipment. The iceberg has literally been instrumentalized: a temporary archipelago, too short-lived to appear on maps, turned into a scientific instrument.

In this context, it's worth revisiting the story of Drift Station Bravo, one of many inhabited icebergs in the Cold War era that had its own postal system, complete with historically unique stamp cancellations.

[Image: Drift Station Bravo postage cancellation mark, via Polar Philately].

As explained on the website Polar Philately, Colonel Joseph O. Fletcher, commander of an Air Force weather squadron stationed in the Arctic, discovered "a large tabular iceberg... that had broken off the Arctic ice shelf... [and] gone adrift." This ice island was soon "codenamed T-1, taken from its original radar designation as a target." Future "ice islands" were codenamed T-2 and T-3.

On March 19, 1952, the U.S. Air Force led by Colonel Fletcher and some scientists landed on this ice island [T-3] in a C-47 aircraft, setting up a weather observation station. Fletcher established a research station that was manned at this big ice sheet for roughly the next 25 years, despite a grim quote given by the head of the Alaska Air Command at the time, a General Old, who was quoted in a Life magazine article of the time as saying "I don't see how any man can live on this thing."

It's worth repeating that Fletcher's team operated this weather station on a repurposed ice floe for 25 years.

Fletcher's Ice Island, and the research station that was located on it, rotated in circles in the Arctic Ocean, floating aimlessly along in the Arctic currents in a clockwise direction. The station was inhabited mainly by scientists along with a few military crewmen and was resupplied during its existence primarily by military planes operating from Barrow, Alaska.

The islandlater renamed "Drift Station Bravo"was inhabited long enough that it actually got its own postal network.

[Image: Letters postmarked from Drift Station Bravo, via Polar Philately].

From Polar Philately:

During the period of active habitation, T-3 covers [postage stamps] were serviced, each stamped with a variety of hand-stamped cachets and markings, dated, and often marked with a manuscript notation of the geographic position of the drifting station on that particular day of ops. The T-3/Bravo covers were often cancelled at Barrow or at a USAF base in Alaska, and then placed in the mailstream.

In other words, envelopes would be stamped with the latitude and longitude of the iceberg at the moment of a letter's departure.

[Images: Postal marking and a letter from Drift Station Bravo, via Polar Philately].

The story takes on clear geopolitical dimensions when we remember that Drift Station Bravo and its ilksuch as Drift Station Alpha, about which you can watch an entire documentary filmwere created in direct response to the Soviet Union's own ice island program. The Soviets "already operated six drifting ice camps of this kind," we read in the documentary transcript, downloadable as a 27kb PDF, but, "owing to the particular strategic importance and sensitivity of the Arctic Basin, little information from these early Soviet stations had reached the West."

The transcript goes on to explain how the U.S managed to architecturally colonize these mobile platforms. Military civilization on the ice established itself as follows:

...a ski-equipped C-47 landed on the ice and deployed the first team of workers. It included an Air Force Major as camp commander and several soldiers with technical skills who had volunteered for 6 months duty on the ice, plus four of the typical tough and versatile Alaskan construction workers.

Modular buildings, called Jamesway huts, camp supplies, fuels, two small World War II Studebaker tractors, called Weasel, and a small bulldozer, were dropped by parachutes.

The story expands rapidly from here. In an article originally published in the September-October 1966 issue of Air University Review, we read that competitive Soviet drift stations apparently discovered a "second magnetic north pole... located near 80° N and 178° W, with magnetic medians extending across the Arctic Ocean," and that sulfuric gas fumes from a badly timed u

In 1886, Los Angeles moved the Fort Moore High School. "A contractor who claimed he could accomplish the task hoisted the building onto scaffolding and, using rollers, horses, and human labor, slowly moved the schoolhouse toward its new location," KCET explains. "After work was underway, the contractor decided that the task was impossible after all. The building remained where his crew left it"unfortunately, not marooned on the stilts seen here, like some steampunk Walking City, but on its new ground-level site blocks away. Once lowered back to earth, it was "repurposed as a schoolhouse for younger students while a new, grander high school was built atop Fort Moore Hill."

It's as if, in a dreamtime state before any of us can remember, buildings once moved around Los Angeles, nomadic titans settling down only with the end of prehistory. Perhaps they will wake up and walk again, criss-crossing valleys, crawling over hills, rearranging roadways around themselves.

Eventually, most of Fort Moore Hill itself was physically removed from the city. "In 1949, construction crews transported away most of the hill by the truckload," we read, turning it into one of the "lost hills of downtown Los Angeles." If only the hill had disappeared, however, leaving all the buildings built upon it stranded on wooden scaffolds in the sunlight, a tablecloth trick in architectural form.

Return of the Brick Swarm

BLDGBLOG 24/12/2011 17:27

A short video has been released documenting the brick swarm project mentioned here last month, in which Swiss architects Gramazio & Kohler deploy semi-autonomous flying robots to assemble a structure of foam bricks. However, it's as if the architects underestimate the interest of their own work, fast-forwarding through the bulk of the assembly process as if no one would want to watch such a thing (or perhaps their robots were less graceful than originally hoped). Either way, check out the results, embedded above.

Speleological Superparks

As part of an overall strategy to rebrand itself not as a city of gambling and slot machinesnot another Las Vegasbut as more of a gateway to outdoor sports and adventure tourisma kind of second Boulder or new MoabReno, Nevada, now houses the world's largest climbing wall, called BaseCamp, attached to the side of an old hotel.

[Image: The wall; photo by BLDGBLOG].

BaseCamp is "a 164-foot climbing wall, 40 feet taller than the previous worlds highest in the Netherlands," according to DPM Climbing. "The bouldering area will also be world-class with 2900 square feet of overhanging bouldering surface."

You can see a few pictures of those artificial boulders over at DPM.

[Image: The wall; photo by BLDGBLOG].

Fascinatingly, though, the same company who designed and manufactured this installationa firm called Entre Prisesalso makes artificial caves.

One such cave, in particular, created for and donated to the British Caving Association, is currently being used "to promote caving at shows and events around the country. It is now housed in its own convenient trailer and is available for use by Member Clubs and organizations."

[Image: The British Caving Association's artificial cave, designed by Entre Prises; photo by David Cooke].

These replicant geological forms are modular, easily assembled, and come in indoor and outdoor varieties. Indoor artificial caves, we read, "are usually made from polyester resin and glass fibre as spraying concrete indoors is often not very practicable. Indoor caves provide the experience of caving without some of the discomforts of natural or outdoor caves: the air temperature can be relatively easily controlled, in most cases specialist clothing is not required [and] the passage walls are not very thick so more cave passage can be designed to go into a small area."

Further, maintaining the exclamation point from the original text: "The modular nature of the Speleo System makes it possible to create any cave type and can be modified in minutes by simply unbolting and rotating a section! This means you can have hundreds of possible caving challenges and configurations for the price of one."

It would be interesting to live in a city, at least for a few weeks, ruled by an insane urban zoning board who require all new buildingsboth residential and commercialto include elaborate artificial caves. Not elevator shafts or emergency fire exits or public playgrounds: huge fake caves torquing around and coiling through the metropolis. Caves that can be joined across property lines; caves that snake underneath and around buildings; caves that arch across corporate business lobbies in fern-like sprays of connected chambers. Plug-in caves that tour the city in the back of delivery trucks, waiting to be bolted onto existing networks elsewhere. From Instant City to Instant Cave. Elevator-car caves that arrive on your floor when you need them. Caves on hovercrafts and helicopters, detached from the very earth they attempt to represent.

This brings to mind the work of Carsten Höller, implying a project someday in which the Turbine Hall in London's Tate Modern could be transformed into the world's largest artificial cave system, or perhaps even a future speleo-superpark in a place like Dubai, where literally acres of tunnels sprawl across the landscape, inside and outside, aboveground and below ground, in unpredictably claustrophobic rearrangeable prefab whorls.

The "outdoor" varieties, meanwhile, are actually able "to be buried within a hillside"; however, they "must be able to withstand the bearing pressure of any overlying material, eg. soil or snow. This is usually addressed by making the caving structures in sprayed concrete that has been specifically engineered to withstand the loads. Alternatively the cave passages can be constructed in polyester resin and glass fibre but then they have to be within a structural 'box' if soil pressure is to be applied."

In any case, here are some of the cave modules offered by Entre Prises, a kind of cave catalog called the Speleo Systemthough it's worth noting, as well, that "To add interest within passages and chambers, cave paintings and fossils can be added. This allows for user interest to be maintained, creating an educational experience."

[Image: The Speleo System by Entre Prises].

As it happens, Entre Prises is also in the field of ice architecture. That is, they design and build large, artificially maintained ice-climbing walls.

These "artificial ice climbing structures... support natural ice where the air temperature is below freezing point." However, "permanent indoor structures," given "a temperature controlled environment," can also be created. These are described as "self generating real ice structures that utilize a liquid nitrogen refrigeration system."

[Images: An artificial ice structure by Entre Prises for the Winter X Games].

Amongst many things, what interests me here is the idea that niche sports enthusiastsspecifically cavers and climbershave discovered and, perhaps more importantly, financially support a unique type of architecture and the construction techniques required for assembling it that, in an everyday urban context, would appear quite eccentric, if not even avant-garde.

Replicant geological formations in the form of modular, aboveground caves and artificially frozen concrete towers only make architectural and financial sense when coupled with the needs of particular recreational activities. These recreational activities are more like spatial incubators, both inspiring and demanding new, historically unexpected architectural forms.

So we might say that, while architects are busy trying to reimagine traditional building typologies and architectural programssuch as the Library, the Opera House

Brooklyn Vent

[Image: Disguised infrastructure; photo by BLDGBLOG].

In the novel Foucault's Pendulum, two characters discuss a house that is not what it appears to be. People "walk by" this certain house in Paris, we read, "and they don't know the truth. That the house is a fake. It's a facade, an enclosure with no room, no interior. It is really a chimney, a ventilation flue that serves to release the vapors of the regional Métro. And once you know this you feel you are standing at the mouth of the underworld..."

[Image: The door to the underworld; photo by BLDGBLOG].

Two days ago, Nicola Twilley and I went on an early evening expedition over to visit the house at 58 Joralemon Street in Brooklyn, with its blacked out windows and unresponsive front door.

This "house" is actually "the world's only Greek Revival subway ventilator" and disguised emergency exit.

[Image: Disguised infrastructure; photo by BLDGBLOG].

According to a blog called the Willowtown Association, "the ventilator was a private brownstone dating from 1847. The substation was built in 1908 in conjunction with the start of subway service to Brooklyn. As reported in the BKLYN magazine article, the building's 'cavernous interior once housed a battery of electrical devices that converted alternating current to the 600-volt direct current needed to power the IRT.'"

[Image: A view through the front door of 58 Joralemon Street; photo by BLDGBLOG].

It is New York's more interesting version of 23/24 Leinster Gardens in London. As the Brooklyn Daily Eagle wrote last year, "the exit disguised as a brownstone leads to a grimy-lit set of metal stairs that ascend past utility boxes and ventilation shafts into a windowless room with a door. If you opened the door, you would find yourself on a stoop, which is just part of the façade."

[Image: Photo by BLDGBLOG].

You'll notice on Google Maps that the 4/5 subway line passes directly beneath the house, which brings to mind an old post here on BLDGBLOG in which we looked at the possibility that repurposed subway cars could be used someday as extra, rentable basement spacethat is, "temporary basements in the form of repurposed subway cars," with the effect that "each private residence thus becomes something like a subway station, with direct access, behind a locked door, to the subterranean infrastructure of the city far below."

Then, for a substantial feeas much as $15,000 a monthyou can rent a radically redesigned subway car, complete with closets, shelves, and in-floor storage cubes. The whole thing is parked beneath your house and braked in place; it has electricity and climate control, perhaps even WiFi. You can store summer clothes, golf equipment, tool boxes, children's toys, and winter ski gear.
When you no longer need it, or can't pay your bills, you simply take everything out of it and the subway car is returned to the local depot.
A veritable labyrinth of moving rooms soon takes shape beneath the city.

Perhaps Joralemon Street is where this unlikely business model could be first tried out...

In any case, Nicola and I walked over to see the house for a variety of reasons, including the fact that the disguised-entrance-to-the-underworld is undoubtedly one of the coolest building programs imaginable, and would make an amazing premise for an intensive design studio; but also because the surface vent structures through which underground currents of air are controlled have always fascinated me.

These vents appear throughout New York City, as it happensalthough Joralemon, I believe, is the only fake houseserving as surface articulations of the larger buried networks to which they are connected.

[Image: Two views of the tunnel vent on Governors Island; photos by BLDGBLOG].

The Battery Tunnel has a particularly noticeable vent, pictured above, and the Holland Tunnel also vents out near my place of work.

[Image: Holland Tunnel exhaust tower; photo via SkyscraperPage.com].

As historian David Gissen writes in his excellent book Subnature: Architecture's Other Environments, New York's ventilation control structures are "strange buildings" that have "collapsed" the difference between architecture and civil engineering:

The Holland Tunnel spanned an enormous 8,500 feet. At each end, engineers designed ten-story ventilation towers that would push air through tunnels above the cars, drawing the vehicle exhaust upward, where it would be blown back through the tops of the towers and over industrial areas of the city. The exhaust towers provided a strange new building type in the citya looming blank tower that oscillated between a work of engineering and architecture.

As further described in this PDF, for instance, Holland Tunnel has a total of four ventilation structures: "The four ventilation buildings (two in New Jersey and two in New York) house a total of 84 fans, of which 42 are blower units, and 42 are exhaust units. They are capable, at full speed, of completely changing the tunnel air every 90 seconds."

Drone Tax

A post on sUAS Newsa blog tracking the "small unmanned aviation system industry"we read about the possibility of drone aircraft being used to enforce residential property tax.

Citing a recent court ruling in Arkansas that "has approved the use of aerial imagery to collect data on property sizes," and making reference to the already-controversial state deployment of aerial surveillance tools, sUAS suggests that drones could someday be used to manage a near-realtime catalog of local property expansions, transfers, and other tax-relevant land alterations.

Whether enforcing local building codeskeeping an eye, for instance, on illegally built structures such as the so-called Achill Henge in Irelandor reconciling on-the-ground property lines with their administrative representations back in the city land archives, how soon will drones become a state tool for regional landscape management?

[Images: Might semi-autonomous systems such as this someday track residential property lines? Images courtesy of Draganfly].

"Imagine your local planning officer having access to your back garden at a moment's notice!" sUAS writes with alarm. "With the pullback from Iraq and other spots under way, this scenario is much easier to imagine. Perhaps it's already happening."

(Thanks to Ruth Lyons for the Achill Henge link).
