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.

Many construction companies require their employees to get either an OSHA 10 or OSHA 30 safety certification, but there are a few different ways to take the courses. Throughout my career, I’ve had safety training in a few different capacity: in-person classroom as part of my construction management degree curriculum, a work organized 10-hour course, and, most recently, an OSHA 30 online course.
For the past 5 years, construction technology company, Procore, has hosted their customers and tech enthusiasts at a multi-day conference called Groundbreak. There’s been significant growth since the events humble beginnings, not only in just attendees, but in the conference’s offerings.
This was my second time attending Groundbreak and, in case you couldn’t make it, here are the highlights of the items you missed:
Tragedy struck in New Orleans over the weekend when an under construction 18-story hotel suddenly collapsed, killing at least 2 with 1 still missing and injuring up to 30 others.
For nearly 3 years, an update to the overtime pay rule was held up in court battles, but we may finally have a resolution. The update sought to increase the minimum salary threshold of workers that are exempt from being paid overtime pay for any overs worked over the traditional 40 hour work week.
If you want your construction company to be best-in-class, you need to be able to objectively measure yourself against them. To help assist with that difficult task, Autodesk has announced the release of a new self-assessment tool to measure where your company stands against your competitors based upon 7 different key performance indicators (KPIs).
In a recent press release, OSHA announced that it has implemented a new OSHA Weighting System (OWS) for their 2020 fiscal year. The change will better help OSHA allocate their resources where needed.
Just days ahead of their annual Groundbreak conference, Procore has announced a new feature upgrade to their platform called Embedded Experience.
Infrastructure projects can require some pretty massive heavy equipment to perform all necessary tasks, so it’s a great opportunity to get some stunning footage of the machines and workers during the process.
Mass timber buildings have been a bit of a hot topic in the construction industry for the past few years, especially after Oregon became the first state to approve mass timber buildings up to 18 stories high, which was closely followed by the International Code Council approval of the same height in 2018.
A few months ago, we wrote about a pretty weird and creepy robot dog that was designed to navigate tough and constantly changing terrain, such as on a construction site. Boston Dynamics, the maker of robot, has now officially announced it is available for sale.
