Last week, Japanese construction workers earned plenty of praise after they were able to repair a gigantic 90 foot by 88 foot by 50 foot sinkhole that formed in Fukuoka, Japan in the middle of a 5 lane road in under a week. A timelapse video of the repair can be watched by clicking here. This week, CNN reported that the road had to be closed again after it began to sink again.
According to the reports, sections of the repaired road sunk up to 2.7 inches (7cm) in some areas causing some public concern. The road has since been reopened, but the road sinking like this should not be a huge surprise, especially to those on the earthwork side of things. After having to fill the hole with roughly 200,000 cubic feet of soil in such a short period of time, it was not possible for the soil to reach peak compaction. Each cubic foot of soil can weigh between 74 and 110 pounds, so, using a conservative estimate of 92 pounds per cubic foot, that’s equals almost 20 million pounds of material. That extreme amount of weight is bound to cause some considerable settling.
The mayor of Fukuoka, Takashima Soichiro, took to Facebook to apologize to the residents for not warning them the road may sink again. It has since been reopened, but the settlement could continue for a while longer. The city recently sustained an earthquake, which measured a 3 on the Richter scale, which may have also contributed to the drop.

Kansas, the state that we can thank for a large portion of our wheat, corn, sorghum, and soybeans, lands just inside the top 10 at #9. With a relatively low population density, ranked 40th in the country, Kansas is also one of the most affordable states to live in. Their cost of living is the 4th lowest int he country, according to MERIC, at 10.3% below the national average.
As mobile apps and project management software are becoming more prominent on construction sites around the world, it’s important that those getting ready to enter the industry, whether it be through college or trade schools, get the training they need to hit the ground running with these programs. PlanGrid,a construction project management and mobile productivity software, has recently announced the release of PlanGrid Schools & Unions, which gives access to hands-on training curriculum and software licenses to industry educators.
Last November, Manhattan District Attorney Cyrus R. Vance Jr. announced felonious assault charges against a contractor’s superintendent and a manufacturer’s branch manager after two men suffered horrific injuries on a New York jobsite. Last week, OSHA formally announced citations against the St. Louis, Missouri based contractor.
“Coolest,” in its very essence, is a very subjective term, but I tried my best to cover construction projects throughout the world that set themselves apart, through either design, construction method, or situation.
When we first began talking about construction technology in 2015, there were a lot of pie-in-the-sky ideas. Many products had financial backing, but no legitimate proof of concept or path to a commercial market. Fast forward just 3 years and many of those same products are starting to hit limited jobsites and have a viable chance to succeed in the industry.
We’ve finally made it to the top 10 on our countdown and the Hoosier State, Indiana, is on the board. The state of Indiana is ranked 38th in total land area, 17th in total population, and 1st in amount of basketball hoops affixed to the side of a barn.
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.
