Construction workers in Moscow using a rooftop crane to lift a giant pane of glass to the top of a 30-plus-story skyscraper will unfortunately have to try it once again. The glass was almost in their reach when the cable apparently snapped, sending the window and its support rig plummeting to the ground.

The plan to 3D-print a bridge in mid-air was always bonkers. How could a technology best known for creating flimsy prototypes and personalized action figures be used for permanent construction projects? Well, the team at MX3D in Amsterdam just answered all of the hard questions and revealed it: the world’s first…

The death toll from the collapse of a pedestrian bridge over a road at Miami’s Florida International University on March 15th has risen to at least six, with the university admitting on Saturday that one of the project engineers had waved off concerns over a crack just hours before.

It’s amazing what kind of useless skills you can teach yourself while you’re bored at work. But twirling pens on your fingers or mastering Solitaire aren’t nearly as impressive as driving an 18-ton front-end loader on two wheels while making the gigantic machine twerk.

A group of Australian bricklayers found a clever to way to work smarter, not harder, by turning the top layer of a brick wall into a run of over-sized falling dominoes. You’ll want to watch the video all the way through, because something completely unexpected happens when the last brick topples over.

You’d assume that when the earth opens up to swallow a big chunk of a crowded city it would take months to fix the damage. But in the Japanese city of Fukuoka, it took repair crews just four days to fix a massive five-lane-wide sinkhole that suddenly appeared last week.

Building a floating city also known as an aircraft carrier is hard as hell to do because the numbers are basically unfathomable. A basic aircraft carrier is made of 60,000 tons of steel, 4.5 acres of non-skid surface with four 325-foot catapults. The whole thing weighs 200 million pounds and takes five years to build…

Tall buildings often have tuned mass dampers hidden inside their structures to stabilize them against the wind. Those tuned mass dampers are huge and heavy and help limit a building’s movement by swaying in the opposite direction of the building. That is, if the wind is making a skyscraper sway to the right, the…

Seeing a train get assembled is a lot like watching someone play with Lego bricks, only if that someone was God and the Lego bricks were stupid ginormous. This timelapse of a London Elizabeth line train being built out at Bombardier in Derby is especially cool because it seems like pieces and parts are just flying…

You know who wins when an angry dude fights an excavator at a construction site? All of us watching the battle unfold from the sidelines, because it gives us the chance to stop and think about the excavators we’re all dealing with—metaphorically.

There are so many dump trucks and pavers and road rollers paving Moscow’s Tverskaya Street in this time lapse that it looks like a massive swarm of machines have taken over Russia. The smaller road rollers look and move a lot like the little planes that launch from the mothership (which, in this case would be the dump…

The timelapse gets a little hectic and sometimes you don’t know what the hell is going on (unless you’re well-versed in canal building), but it’s just crazy to see a strip of land get carved out and then built out with concrete. Like, we just really gashed the Earth and filled it up with water.

Bad idea: trying to use a crane to lift a water tank before checking if it’s empty or not. You can see the crane’s arm begin to buckle under the weight of the tank and then watch it totally collapse as it drops the tank onto the side of the building and flips itself off the ground.

Cruise ships are basically giant floating cities. How do you build a giant floating city? Well, it’s pretty much like playing with Lego bricks. This time lapse shows the construction process of building AIDA Cruises’ new flagship in Nagasaki: the AIDAprima. The AIDAprima can hold up to 3,300 passengers with 900 crew…

Two hours outside of Paris stands Guédelon, a castle that looks like it’s from the medieval period, but is actually being constructed right now. What’s more, the castle isn’t being built with new technology but instead with medieval techniques and materials. That means every stone, every tile, every single part of the…

Any man worth his salt should know the difference between cement, concrete, and mortar. I am not that man. They’re all just gray sludge to me. But This Old House explains the difference between the three in a very easy to understand way.

Any type of tree house rules. Throw a shanty on a tree trunk and the world immediately becomes a beautiful place. This tree house, though? This tree house is legitimately awesome. In the woods and next to the water, it has a bridge, windows, a deck, and basically everything you ever wanted in a tree house.
