One of the challenges with construction is determining how your work can and will affect the existing conditions surrounding your job site. That’s why it’s increasingly important to not only perform proper due diligence procedures, but also react to the findings. That, unfortunately, doesn’t always happen and could potentially be what caused a massive sinkhole in Fukuoka, Japan, last week.
Around 5:15am local time, a 98 foot (30m) by 88 foot (27m) section of roadway was completely swallowed by a sinkhole. As crews were working on an underground subway line directly beneath the road, groundwater began to flow into the tunnel, according to the Asahi Shimbun. Shortly after, the road above began to collapse, exposing a flowing sewer line under the pavement. Luckily, no injuries were reported, but hundreds of residents and businesses were without power or gas, as the nearby utilities were compromised. Due to fear of the sinkhole growing, city officials ordered the hole to be filled in later that afternoon.
Perhaps even more astonishing, repairs have been made to all the utilities and the pavement in a week’s time, as the road was opened back up to the public on November 15th. After the hole was filled in, it only took crews 48 hours to repair the utilities and re-pave the roads, according to CNN. The 50 foot (15m) deep hole took roughly 8,100 cubic yards (6,200 cubic meters) of a sand and cement mixture, which the mayor of Fukuoka says is now 30 times stronger than before, reported the Guardian.

Everyone has a camera in their pocket these days and when something goes down on the jobsite, you can bet it’s going to be captured on video one way or another. That can either be a great thing for marketing or an awful way to showcase your business.
Look, you could mobilize on site the boring old way by loading your heavy equipment on the bed of a trailer and driving it to site, or you could take a note from the Bravo Company of the 37th Engineer Battalion of the United States and spice things up a bit.
“World’s Largest” is definitely a sought after goal, especially in the construction industry. Sarens, a crane rental, heavy lifting, and engineered transport company in Belgium, has recently released a supersized crane that is being regarded as the largest crane in the world, by both size and lifting capacity.
Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
A construction crane that was working on a highway widening project in St. Martin Parish in Louisiana collapsed onto the adjacent roadway last week, injuring one driver.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
Cranes are an extremely useful and important piece of equipment on the majority of construction sites. They can also be extremely dangerous if they are not understood or respected.
