We have the technology … why not wear it?

As the wearable technology market continues to grow, we round up a few of the newest and most innovative articles of attire intended to boost safety and productivity in construction.

Lending a bionic hand

Ekso Bionics’ Zero-Gravity Arm aims to make operating heavy hand-held machinery easier and safer. The company gained its rep producing exoskeletons—wearable robotic aids for soldiers and the partially paralyzed—and is now branching out into bionics for the construction trades.

Ekso’s new Zero G arm renders power tools (up to 36 pounds) virtually weightless. Though exoskeleton technology takes some getting used to, noted a Wired reviewer, the effect is to enhance the user’s strength, mobility, and endurance. The system works on the same principle as the Steadicams used in Hollywood, swiveling about on springs and counterweights. The bionic arm also absorbs the powerful feedback produced by power tools, reducing strain on the worker.

When put to the test (see video below), a worker using the zeroG arm completed a jobsite task not only faster, but with more accuracy and much less fatigue. Meanwhile, a worker using the traditional method tired sooner, and took far longer to complete the task:

Tactical textiles

In Britain, more than 10,000 insurance claims have been made for vibration white finger and carpal tunnel syndrome over the past decade, according to the British Health and Safety Executive. That’s a cost of £20 million to £250 million (or roughly $25 million to $322 million). And these conditions result from continuous operation of vibrating hand-held machinery.

Seeking to combat these permanent industrial diseases, a new wearable technology being developed at Nottingham Trent University in the UK warns construction workers when a hand injury is imminent. The e-gloves, not much bulkier than average heavy-duty work gloves, are embedded with tiny sensors that warn workers when they’re exposed to dangerous levels of vibration.

Only 2 millimeters long, the sensors are imbedded into a yarn textile and knitted into the gloves. The seemingly simple technology performs an impressive safety duty. When triggered by dangerous levels of vibration, these tiny sensors warn wearers to stop work.

Vested interest

Redpoint Positioning has developed an innovative safety vest that protects workers and has the potential to improve incident reporting, drive efficiency, and cut costs.

Embedded with Redpoint’s indoor GPS tracking system, this high-tech personal protective equipment (PPE) gives full visibility to jobsite operations. When a worker enters a designated “danger zone” on the jobsite, it triggers the vest’s flashing red lights and audio feedback, while managers receive customized digital data on the worker’s location. The data is tracked and logged to help manage on-site safety practices.

Redpoint calls the technology a “wireless safety net,” lending an integrated approach to PPE. Of course, some workers might chafe at the thought of being tracked, and it is important not to abuse the technology, said Gary Cunningham, recently retired as Suffolk’s national safety director. “It has to be a partnership,” Cunningham said, with the shared goal of reducing injuries.

But “if you’re afraid of a tracking device,” said Suffolk Senior Safety Manager Joe Villela, “throw away your cell phone!” At 1700 Webster in Oakland, Villela gave workers radio frequency identification (RFID) tags to wear. “The whole point is safety,” he said. “In case of a catastrophic event, such as an earthquake—which on the West Coast we know is not a matter of if but when—we can make sure everyone is out of the building.”

The RFID tags, from Trimble, were effective, though they weren’t as flashy (literally) as the Redpoint vests:

A step forward for construction footwear

SolePower founder Hahna Alexander was recognized by Toyota’s “Mothers of Invention” female entrepreneurs’ series. Her innovation: generating electricity through footsteps. Alexander found a way to harvest kinetic energy from the human motion of a heel hitting the ground. The energy then transfers into a mechanical system, which, in turn, uses it to spin a micro-generator. In simple terms, human energy fuels kinetic chargers, providing a better, lighter power source.

This power source, when placed inside the back of a work boot, wirelessly gathers data and measures worker safety, efficiency, and productivity. The SmartBoot technology promises to keep workers safe, fit, and productive, and could be valuable on a worksite in lowering accident rates, tracking hours and monitoring workers’ locations in the event of an emergency. In turn, these incredible Smartboots could save money, lives and time, and improve incident reporting accuracy on the jobsite.

Stop the sway, a simpler way

Streamlining the counterweight systems that limit a building’s wobbles

Take note, high-rise builders and daring designers. You know those giant counterweights, called tuned mass dampers, that keep spindly skyscrapers and bridges from swaying in the wind? Well, now there’s a pint-sized portable tuned mass damper.

Wait a second. How does a regular tuned mass damper even work? A little background: especially at great heights, a structure can be strong without being stiff, and when it lacks stiffness relative to the forces acting on it—wind, footfalls—it can swing perceptibly. The building won’t topple, but the movement can cause occupants alarm, discomfort, even nausea. A notorious example, Boston’s John Hancock Tower, swayed as much as three feet off its base before dampers were added.

Increasingly common in Manhattan, the typical tuned mass damper (TMD) is essentially an enormous counterweight on springs or a pendulum, built into the top portion of a tower. When high winds push on the building, the weight swings in the opposite direction, staying the tower’s shift. But in order to make it work, engineers have to “tune” the damper to match the building’s natural frequency, ensuring that the weight swings just enough to counteract the wind. (Frequency being the speed of a vibration.) Practical Engineering explains it all with a fun video here.

The drawbacks are size and cost. For example, the 728-ton steel ball that stabilizes the 1,667-foot-tall Tapei 101 tower in Taiwan cost $4 million—and it takes up six stories of prime real estate.

A lighter package

By contrast, a portable tuned mass damper, under development at Virginia Tech, weighs about 275 pounds. And a building owner with no technical training can adjust the damper’s settings with a five-dollar iPhone app.

Of course, the damper itself will cost more than $5, but it will be affordable, says its inventor, Mehdi Setareh, an architecture professor and the head of the Vibration Testing Lab at Virginia Tech. “What I’m trying to do is reduce the cost so it can become more common,” Setareh told us. “It’s like what Henry Ford did with cars.”article-image.img.490.high

Setareh’s invention is best suited to those modern buildings constructed of lightweight materials and given swooping, eye-catching shapes with computer-aided design. Setareh is himself an award-winning structural engineer who helped design the dramatically cantilevered headquarters of MFP Automation Engineering (right).

Such bold designs have become more common—and along with them, so have complaints about noticeable vibrations, according to Setareh. His lab has studied and helped modify structures such as a theater balcony in Detroit and the monumental stair in the Zaha Hadid–designed Broad Art Museum in East Lansing, Michigan (left). “The floors are designed for strength,” Setareh hastened to point out. “When people walk on the floor, it holds the load, no problem.” But a slight bounce gives users the unwelcome impression of shakiness. “It can be scary, or at best annoying.”

Rather than sacrifice aesthetics or boost costs by building with heavier beams, said Setareh, architects (or, after the fact, building managers) can apply a simple fix. Acting like a shock absorber, the portable tuned mass damper (PTMD) consists of a weight on springs, tuned to have a natural frequency close to that of the floor. When the floor is rattled by foot traffic, the springs are activated and the movement of the weight pushes back against the movement of the floor, neutralizing it. “When the floor goes down, the damper mass goes up,” Setareh said, “and when the floor goes up, the mass goes down.”

The device sits two feet high and weighs a fraction of the floor, but it compensates by moving ten to twenty times faster than the floor vibrates. “So even though the mass of the [PTMD] is, say, 200 pounds, it’s like 4,000 pounds of force moving against the floor,” Setareh said. “That’s how it reduces the vibration substantially,” up to 60 percent in the Virginia Tech lab’s testing facility (see below).

A result of rocketry

That’s a fine solution for a variety of unique buildings—hospitals, theaters, corporate headquarters. But what about a straightforward residential high-rise? It’s hard to imagine a small, convenient version of the titanic TMD at Tapei 101.

And yet, a team at NASA has developed a damper the size of a coffee can (though it sits in a long pipe filled with water) that can stop a tall building’s shakes in a heartbeat. Spun off from rocket technology, a variation of this “disruptive tuned mass” has been installed on the new 32-story 461 Dean in Brooklyn, the world’s tallest modular building. It turns liquid into a secondary mass that absorbs and dissipates the energy of a building’s vibrations.

Engineering firm Thornton Tomasetti licensed the technology and adapted it to 461 Dean (right), which is built of lightweight steel modules. Thornton Tomasetti’s rooftop system, which they call a fluid harmonic absorber, consists of four U-shaped PVC pipes, each 50 feet long and three feet in diameter. Air springs are fitted to the outside of the pipes and tuned to a certain “sloshing frequency,” explained Michael Wesolowsky, a Thornton Tomasetti engineer. The tubes are pressurized so that during a wind or seismic event, air pushes on the water, and then vice versa.

“The liquid is tuned to slosh back and forth at exactly the same frequency as the building’s movement, but out of phase,” said Wesolowky, “pulling the building back in the opposite direction,” thereby keeping it steady.

“It’s like the air spring in your car,” added Elisabeth Malsch, another Thornton Tomasetti engineer, “if you have a newer, fancier car.”

Already, the system has performed well on high-wind days, Malsch said. And it has advantages over the gargantuan conventional TMDs. The absorber at 461 Dean (the first of its kind in a commercial application) is “cheaper, lighter,” said Malsch. “It required very little reinforcement” to the building below. It’s also easier to tune, not to mention maintain. After all, “we know how to patch leaks in pipes,” Malsch said.

Like the PTMD out of Virginia Tech, the fluid harmonic absorber can be installed after initial construction is complete, if a structure turns out to behave differently than predicted in high winds. The Smithsonian speculated that historic landmarks built before earthquake codes might be retrofitted with the NASA-bred system, another benefit of which is its fast-acting nature. (Skyscrapers can still sustain damage during the few seconds it takes for a quake to activate a conventional, pendulum-style damper.)

Malsch can attest that older buildings are good candidates for the addition of such a cutting-edge streamlined damping system. Her office is in Manhattan’s 40 Wall Street, at 71 stories the world’s tallest tower when it was completed in 1930 (before being surpassed by the Chrysler Building a few months later). On windy days, the structure’s age is apparent—or audible.

“Every six seconds,” said Malsch, “you can hear it creak.”

The Space Needle, the Jetsons, and what today’s futurists see for tomorrow

It looks like a flying saucer, perched atop spindly, upward-swooping legs. It’s as if a UFO and its exhaust trail were frozen mid-takeoff. Like something out of a sci-fi movie. And that’s the point.

In case you missed it, the Seattle Space Needle recently turned 55—old enough to get the senior discount at Old Country Buffet. Much like the Eiffel Tower in Paris, the Space Needle was built for a World’s Fair; attracted its share of criticism; and is now a landmark that defines its city’s skyline. And while this Space Age artifact may seem a tad dated now, its influence has rippled across the decades and perhaps—if a company called Arconic fulfills its vision—will continue to alter skylines in 2062.

Speedy in Seattle

The Space Needle was conceived as the centerpiece of Seattle’s Century 21 World’s Fair, a showcase of tomorrow’s technology. It was vintage midcentury: can-do optimism, tinged with Cold War urgency. The Soviet Union had shocked Americans when it sent the first satellite into orbit in 1957, kicking off the international space race. But in the JFK era, with federal dollars flowing to scientific research, and finned automobiles speeding down superhighways, anything seemed possible.

Rising 605 feet high—then the tallest structure west of the Mississippi—the Needle was built in just 400 days, at a cost of $4.5 million. The foundation, which was 30 feet deep and 120 feet across, took 467 cement trucks about twelve hours to fill. It was the longest continuous concrete pour attempted in the West at that time.

Including 250 tons of rebar, the foundation weighs 5,850 tons; the Needle structure itself weighs 3,700 tons. This means its center of gravity is just five feet above the earth’s surface. The Needle is fastened to the foundation with 72 thirty-foot bolts.

Not only can the Needle survive earthquakes (e.g., one in 2001 that measured 6.8 on the Richter scale), but it was designed to withstand winds of up to 200 miles per hour—double the code requirements in 1962.

But what struck most was the daring design of the tower and its bulbous top house. The spacecraft look was deliberate. Initially, the building was painted with colors “Astronaut White,” “Orbital Olive,” “Re-entry Red,” and “Galaxy Gold.” As the building seemed to reach for the stars, it signaled a nation’s upward progress.

Construction was completed in December 1961. The Needle’s signature rotating restaurant held an opening gala on March 24, 1962. The Century 21 World’s Fair officially opened on April 21.

Seattle_Space_Needle_CropUnlike other architectural relics of the period—e.g., unloved Brutalist exemplars such as Boston’s City Hall and the Salk Institute in La Jolla, California—the Space Needle appears on T-shirts and postcards, earned official Seattle landmark status at age 37 (in 1999), and remains one of the city’s most popular tourist destinations. While many Sixties buildings raised eyebrows, the Needle prompts smiles as well. It may be that, along with its aspirational spirit, the tower’s very cartoonishness is what makes it so endearing—and enduring.

The Jetsons connection

That drawn quality quickly translated into actual cartoon form when The Jetsons debuted on TV in September 1962. The series imagined a family in 2062. The Jetsons and their contemporaries drove flying cars, employed robot maids—and lived in high-rises that looked a lot like the Space Needle. In case you were deprived of re-runs as a child, here’s the program’s opening:

The resemblance of the Jetsons’ home to the Space Needle was no accident, animator Iwao Takamoto told the New York Times in 2005. The “skypad” on stilts took direct inspiration from the Seattle tower.

Art imitates life, and vice versa. A new engineering company called Arconic—spun off the aluminum giant Alcoa—has taken inspiration from The Jetsons to reimagine the world of 2062. Arconic’s updated Jetsons drive flying cars and live in skypads that make use of technologies currently in development or, in some cases, available already. The company hired filmmaker Justin Lin (Star Trek Beyond) to illustrate their vision with this video:

Arconic’s futurists predict that three-mile-high skyscrapers will be built using 3D printing. The technology will allow for more organic, nature-inspired shapes. “I think you will see less of the square, boxy shape of current skyscrapers,” Arconic’s Don Larsen says in another promo video.

Arconic skyscraper

Furthermore, Arconic hopes those skyscrapers will employ their products such as Bloomframe. This is a motorized window that transforms into a balcony in less than 60 seconds.

hofmandujardinwelcomebloomframe03tileMoreover, those windows would clean themselves—and the environment—if coated with EcoClean, an Arconic product already on the market. This titanium dioxide coating absorbs light and water vapor, activating free radicals (the atom-sized variety), which suck up and eliminate dirt as well as pollutants in the air around a building.

Will Arconic’s vision come to pass by 2062? Nobody can answer that. But the company is making a big bet on it, investing millions in advanced materials and technologies. At a time when much of the talk nationally is about fear of the future and a return to the past, Arconic’s embrace of a bright tomorrow is refreshing. So it’s no surprise we can trace the roots of this campaign to the audacious tower that rose over Seattle to celebrate and imagine the 21st century, back in 1962.

High tech, low bar

No learning curve with these AEC innovations

Your workload is big enough already. You don’t want to spend a lot of time learning how to use a new tool. Of course, the up-front investment of time should translate into time savings down the road. Yet the reluctance to learn something new, along with other factors, can pose a big barrier to tech adoption.

So it’s welcome news when an innovation promises to improve practices or workflow without requiring a day to figure out how to use it. In that vein, we take a look at some new products with potential. These advances in familiar technology aim to improve upon things you already use, whether in the office, trailer, or job site.

A VR vision, easy to view

“For a technology to crack the mainstream,” wrote the New York Times in January, “there is an unspoken understanding: It shouldn’t make the people who use it want to throw up.” And yet, the Times reported, at the International CES trade show in Las Vegas, the presenters of one 3D headset made barf bags available to users, just in case. It seems that wearing virtual reality goggles can be not only disorienting but sometimes literally nauseating.

A new app called Building Conversation removes these barriers by putting virtual and augmented reality on a tablet or smart phone. Imagine an architect and a developer standing at the edge of an empty lot. The architect simply hands over an iPad; the developer aims it at the site; and a 3D vision of the tower appears on the screen, overlaid atop the real-life view. If their meeting takes place instead in a boardroom, the tablet can be pointed at the table, where, through the screen, a holographic model of the building appears. A contractor and subcontractor can use the app to virtually walk through a model of the building. In whichever mode users select, they can pan through or around the image as they move. No goggles—or barf bag—required.

There’s less of a “wow” factor than with an immersive headset, but the image is clear enough and the ease of use can’t be beat. Plus, by allowing stakeholders to literally share the vision, passing the tablet back and forth and looking at the same 3D image together, this twist on VR/AR technology brings back the human interaction that is essential in project development.

Construction of tomorrow inspired by insects?

We think of termites as agents of destruction. Here in North America, the little buggers chew through untreated wood and give homeowners headaches. But in the Southern Hemisphere, colonies of termites—each less than a centimeter long—collaborate to build complex mud mounds rising up to 25 feet high.

The bugs do this without a blueprint or any supervision. There’s no tablet-toting termite foreman directing the workers. Nor is there specialization among workers. Each termite has the same, limited set of skills. As individuals, they’re expendable: If a human steps on some or an aardvark slurps up a bunch mid-task, the others take up the slack. But because there are a million of them to a colony, the insects—sharing a collective goal and a few instinctive rules—eventually get the job done. (It can take a year, or years, just like our own skyscrapers.)

To a few Harvard scientists, these massive mound projects begged the question: Could the same principles be applied to robotic builders?

Justin Werfel, Radhika Nagpal, and Kirstin Petersen form a joint team from Harvard University’s Wyss Institute for Biologically Inspired Engineering and School of Engineering and Applied Sciences. Their ongoing research is so far most notable for the Termes experiment, in which small, simple robots worked independently to build proportionally large structures, without a human or even a smart computer coordinating their efforts—at least, not in the way we might think of it.

The experiment made waves after the journal Science published the results in February 2014. Since then, the Harvard researchers have been traveling to Namibia to learn more about the termites that inspired the project. Werfel, who has also authored a book chapter on the ecology of Fraggle Rock (remember the Doozers?), walked us through the Termes project.

Of whegs and stigmergy

The Termes system was realized both in computer simulations and in a physical lab setting. “In the simulations, you’ve got dozens of robots building enormous skyscrapers flawlessly,” said Werfel. In the latter—i.e., the hardware—came the true test. Built by Petersen, the three Termes robots measure about seven inches long and 4.3 inches wide. Each is equipped with infrared and ultrasound sensors, a clawed arm capable of lifting in the manner of a front-loader, and a kind of tail to aid in carrying cargo.

The robots move about on “whegs”—combination wheel-legs, in a triskelion shape (like on the Manx flag). This is to help the robots climb up and over the blocks they’ve already laid. Though the Harvard team didn’t invent whegs, Werfel recalls learning about wheels with protruding sticks for enhanced mobility when, as a child, he saw the following TV commercial:

As with termite workers, no one Termes robot has a special skill or role. Each is capable of the same few simple tasks—walking and climbing, picking things up and putting them down.

The bots’ building materials are interlocking foam blocks, shaped somewhat like electric beer coasters—the kind that flash and hum when your table is ready at the steakhouse. The blocks fasten together magnetically, so the robots don’t have to be precise when stacking them. They’re also notched at the edges, aiding the robots in gaining a foothold as they climb up or walk across them.

Werfel’s team fed the robots the design plan for a structure, such as a staircase or a pyramid—which are, not coincidentally, well suited to the robots’ climbing ability. The bots were also coded with a set of “traffic laws” to avoid crashes.

From there, the robots were on their own. To make the system work the way termite colonies do, Werfel said, “the robots need to be independent; they need to have knowledge that only they can sense themselves; they’re going to be building large-scale [structures]; they’re going to be climbing over things they build in order to get to higher places they couldn’t otherwise reach . . . and they’ll be coordinating through indirect communication.”

That indirect communication occurs “via the joint manipulation of a shared environment,” as Werfel wrote in the Science article. In other words, as the robots work in parallel, moving blocks around, they leave one another cues (and in turn pick up on cues) as to what should be done next. This form of communication by implicit coordination is called “stigmergy.”

In this decentralized approach, there’s no prescribed order in which the robots must stack the blocks, just a prescribed outcome. It’s up to the robots how they get the job done. (Not that they plan this in advance, since they’re simply behaving reactively—remember: stigmergy.)

termes-simulation-graphic

The advantage with such a system of several unsophisticated robots is that there’s no single failure point. If one of the robots falls on its back and can’t get up, the other two keep working and finish the job. That said, little failures in the hardware sometimes added up to an overall failure, as when a robot fell in a spot where the others couldn’t pass it. “And we didn’t have a tow truck,” said Werfel. “Well, we did; it was Kirstin. In a real system, you’d want a tow truck.”

Nevertheless, the robots ultimately succeeded in building a structure ten blocks tall. In Werfel’s terms, they proved that an emergent outcome can be engineered into a system of low-level independent agents. Check out the time-lapsed video, below, showing the Termes robots at work:

Out of the lab

So will giant Termes-style autonomous robots build high-rise hospitals or luxury condo towers in the middle of dense cities with no supervision? Not likely in our lifetimes. However, we might well see such robots in action during a flood, piling sandbags to build emergency levees. Or in another disaster scenario, Werfel suggested, the robots could enter an area struck by an earthquake to shore up a shaky building. “You don’t want to send in people because the building could actually collapse while you’re trying to reinforce it,” he said. After all, the robots are expendable, while people aren’t.

In the more distant future, Werfel envisions similar robots being used to build Martian homes or deep-sea research stations in advance of human explorers’ arrival, or in other situations when it could be considered highly impractical or prohibitively dangerous to employ us flesh-and-blood types.

Paradoxically, if such high-tech facilities can be erected without the loss of a single human life or limb, we’ll have the lowly termite to thank for the inspiration.

3D-printed buildings: Is the future already here?

“Soon, we will be able to construct an entire building … with a printer.”

That was the headline for our blog story posted back in March 2015. It is now August 2016 and “soon” has arrived. A company called WinSun, which was featured in our previous 3D printing blog post, recently took another bold step forward in the “3D printed building movement.” The company announced — through its partnership with the country of Dubai, which is aiming to be the world leader in 3D printing — that it has built the world’s first fully-functional 3D-printed office building, dubbed the “Office of the Future.”

At more than 2,600 square feet, a building of this size would typically take five to eight months to build using traditional construction means, methods and materials. However, C|NET Magazine reported that it took a mere 17 days to print the building components layer by layer using a cement mixture. The 3D printer used for printing the building components was a massive machine, the size of a warehouse that stood 20 feet high, 120 feet long and 40 feet wide. It also took only two days to assemble those building components, with just a fraction of the manpower that would be required to construct a similar building this size.  In all, “Office of the Future,” which was designed by HKS Architects, cost only $140,000 to build, saving approximately 50 percent of the normal labor cost.

Saif Abdullah Al-Aleeli, CEO for the Dubai Future Foundation, which is the organization that occupies the new building and is charged with the creation of other futuristic structures for Dubai, believes that “20 years down the road entire cities will be 3D printed.” So what do you think? Is the future of 3D-printed buildings really here?  We’d be interested to hear your thoughts…comment below!
