\"\"The construction site hasn\u2019t changed much over the years. Humans in hard hats still scurry across scaffolding, lay rebar, and\u00a0pour concrete. While automation has transformed the world of manufacturing, construction remains relatively untouched by self-sufficient machines. That is about to change. Artificial intelligence, 3D printing, and robotics are poised to bring automation to building construction. Here we examine six technologies likely to be found on the construction site of tomorrow.<\/p>\n

1) Mesh Maker<\/strong><\/p>\n

ETH Zurich\u2019s\u00a0in situ<\/em>\u00a0Fabricator\u00a0will soon be laying down bar for D\u00fcbendorf\u2019s NEST (Next Evolution in Sustainable Building Technologies). The building is meant to be a primarily digitally produced structure. To that end, the Fabricator, a\u00a0robotic arm\u00a0on caterpillar tracks, will be constructing a double layer of metal bars. This mesh framework will subsequently be filled with concrete. The free roaming robot, using the Mesh Mold technology, as they call it, can create a framework that bends and waves, allowing NEST architects to design non rectilinear walls.<\/p>\n

2) Brick Layer<\/strong><\/p>\n

Not all walls are concrete, of course. The traditional brick wall is built brick by brick, each one put in place by human hands. But a typical bricklayer can only place something like 500 in a day. Construction Robotics\u2019 Semi-Automated Mason, or SAM, can put down 6,000 per\u00a0day, with mortar. SAM won\u2019t eliminate all human workers, though. They\u2019re still needed to tidy up the \"\"mortar and load SAM. But the\u00a0heavy lifting\u00a0will be done by the machine, saving a few backs and a few bucks as it raises brick walls faster than ever.<\/p>\n

3) 3D Printing, Gantry Style<\/strong><\/p>\n

3D printing has been building walls a layer at a time for a few years now. In some cases, like the structures from China\u2019s WinSun, those walls are built in sections and trucked to a site where they are assembled. Other systems do their printing on site. Copenhagen\u2019s BOD building (for Building On Demand) will be made this year with a gantry printer capable of putting down layers of concrete 50 to 70 millimeters thick at 2.5 meters per\u00a0minute. The concrete it will use is mostly made from sand and recycled tiles. One of the pioneering companies for 3D printing in construction, Contour Crafting, will also have a system for sale to construction companies later this year.<\/p>\n

4) Drone Builds<\/strong><\/p>\n

3D printed buildings are limited by the gantry\u2014or the robotic arm\u2014that prints them. Not only are they constrained by the physical size of a printer, a large site can\u2019t really use more than one at a time, as they get in each other\u2019s way. So instead of one giant autonomous builder, why not use hundreds, or thousands, of tiny ones? A swarm of robots could be capable of \"\"working together on a building of unlimited size, without colliding. Harvard researchers have created brick-laying\u00a0termite bots, for instance. But the most untethered of robots is the drone. Researchers at ETH Zurich managed to use a few quadcopters, working in harmony, to build a rope bridge. If we can solve the small issue of power, drones could bring any material to any point in space for any kind of building.<\/p>\n

5) Artificial Intelligence<\/strong><\/p>\n

No 3D printer, drone, or robotic arm will be of much use without quality software. For robots to successfully take over the construction site, they\u2019ll need good intelligence, of the artificial kind. With AI, constructor bots will know where they and each other are at all times. They\u2019ll also learn as they go. Deep learning is already being put to use on human dominated construction sites. The folks at\u00a0Smartvid.io\u00a0have used the millions of photos and videos taken of construction sites to teach their program what unsafe conditions looks like. Anyone on a construction site can take a picture of a portion of that site and have Smartvid.io\u00a0identify potentially unsafe areas. Similar technology could one day guide robots to fix errors they\u2019ve made, or at least to flag a human when they see something dangerous.<\/p>\n

6) Foam Spewing Arm<\/strong><\/p>\n

MIT\u2019s\u00a0Media Lab\u00a0has used an existing industrial robotic arm to create the Digital Construction Platform. Untethered by a gantry, it has the ability to travel anywhere at a given site, constructing as it goes. This year the researchers used the DCP to create a 12-foot high, 50-foot diameter dome out of foam insulation. The process took only fourteen\u00a0hours. The foam of that structure, or of any similarly constructed building, could easily be fitted with rebar and filled with concrete.<\/p>\n

\"\"\u00a0\u201cUnlike direct extrusion of concrete, with print and place\u00a0you are not changing how the structural elements of the wall are assembled,\u201d says Julian Leland, a mechanical engineer who worked on the project. \u201cYou could\u00a03D print\u00a0a formwork that looks exactly like conventional insulated concrete formwork. As long as the rebar structure and the concrete mix, and the way you poured it and treated it after, as long as that meets building code, we have reason to believe that the structure would meet building codes, at least in the US.\u201d<\/p>\n

Though some of this technology has a long way to go before it becomes a reality, much of it is practically ready to go. The primary reason we don\u2019t see robots erecting buildings is the industry\u2019s resistance to change.<\/p>\n

\u201cThe construction industry has a well-developed model of how to build buildings, how much those buildings are going to cost, what labor is required, et cetera\u201d Leland says. \u201cThey don\u2019t want to tinker with that.\u201d<\/p>\n

To get their technology working on actual buildings, it might be better for researchers to approach architects, who are more eager to turn to the cutting edge. But however we get there, it\u2019s undeniable that there is a time coming when buildings will practically raise themselves.<\/p>\n","protected":false},"excerpt":{"rendered":"
