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.

At the National Safety Council Congress & Expo on September 10, 2019, OSHA’s deputy director of Directorate of Enforcement Programs, Patrick Kapust, announced their preliminary list of the 10 most frequently cited safety violations for their fiscal year 2019.
A few technology companies have been trying to wedge augmented reality into construction for a few years now, boasting benefits of overlaying BIM models onto the real life site you’re working on, as well as interactive collaboration with remote workers. One of those companies that we thought was going to make a pretty big impact is apparently closing its doors in the near future.
The most popular method of demolition these days is by implosion, but not always welcome in certain areas or situations. The use of explosives can greatly damage neighboring buildings and spread hazardous materials over a large radius, which is why a cooling tower at the Mülheim-Kärlich power plant in Germany had to be slowly dismantled from the top.
Late last year, crane manufacturer, Sarens, announced that their brand new – and enormous – crane, was ready to be sent off to it’s first job. After several months of prep, the Sarens SGC-250 has finally made it onto its intended jobsite and is ready to lift.
For the past few years, tool manufacturers have been making cordless tools possible that no one thought could be done. We now have battery powered table saws, 12” miter saws, even battery powered pipe threaders. But one thing that no one has done yet, until now, is a battery powered worm drive circular saw.
It’s no secret that the construction workforce is dominated by men, but women are slowly increasing their numbers in recent years as gender barriers continue to be knocked down. With construction jobs expected to continue to grow over the next few years, women will play a significant role in filling job openings.
Construction employers are legally responsible for following and enforcing safety regulations on their jobsites. If caught not abiding by these rules and failing to keep workers safe, an OSHA violation and fine can follow. Recently, however, several contractors are also facing criminal charges following employee deaths on their jobsites.
After causing devastation in the Bahamas, Hurricane Dorian worked its way up the U.S. East Coast last week and eventually made its way up to Nova Scotia, Canada as a Category 2 storm. The storm left more than 369,000 without power in the Canadian Region, according to CBC, but also caused a tower crane to buckle and collapse in the city of Halifax.
A little over 3 years ago, reports surfaced that San Francisco’s luxury high rise, the Millennium Tower, has been consistently sinking and tilting since it was completed in 2009. Lawsuits have been underway for years involving dozens of lawyers from many different parties, but an expert panel has just approved a $100 million plan to keep the building from sinking and tilting any further.
If you are looking for the right scaffolding for your construction project, you will need to consider the choice of scaffolding available to you. However, there is one type of scaffolding that is chosen for a number of different projects because of the benefits that come with it. This kind of scaffolding is Mobile Scaffolding and regardless of whether you are working on a roof or working on the brickwork of a building, they are often a great choice.
