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.

One of the best parts (for me, anyway) of large developments that cost hundreds of millions of dollars being built is being able to learn about different construction methods that can reduce costs or deliver the project sooner than traditional methods. The Crown Sydney, a future 890 foot tall tower in Australia, is using a method called “top down construction” to shorten their project schedule and avoid additional hazards on the $740 million project.
If not for having the lowest cost of living in the country, according to the MERIC data, MIssissippi would be in contention for the lowest ranking on our list. However, having a 14.5% lower than the national average boosted the state up 15 spots to #35 after adjustment.
In January of 2018, ten construction workers were killed and another eight were injured when a bridge spanning the Chirajara canyon in Columbia partially collapsed. That collapse has since been blamed on a poor design, reports have stated. Last week, the remaining sections of the bridge were demolished in dramatic fashion.
A 47 year old crane operator is facing charges of driving while intoxicated and leaving the scene of an accident after driving a truck mounted crane into several vehicles on the Long Island Expressway in New York.
OSHA's new crystalline silica dust exposure regulations officially went into effect on September 23, 2017. Over the past 10 months, there has been plenty of confusion about the lung disease causing material. In the first 6 months after the effective date, OSHA's inspectors yielded 116 violations across the country.
Vermont is one of the few states in the Northeast that doesn't have a ridiculously high cost of living, according to MERIC, at only 2.9% higher than the national average. That helped Vermont rank higher than many others in the Northeast in this list, but it's lower than average adjusted hourly rates for the construction industry still kept it on the bottom half of the list overall.
A couple weeks ago, we shared a list of the 100 tallest buildings to ever be demolished. One of the most interesting things that I learned while researching for that article was that although Detroit’s Greater Department Hudson Store was not the tallest building on the list (it was #21), it was the tallest on the list to actually be imploded.
Since the dawn of green buildings, these projects have always been synonymous with LEED certification. The process of obtaining that LEED certification has not always been an easy one for contractors; there is a ton of paperwork and documentation that needs to take place in order to prove all LEED credits have been rightfully earned. A new construction standard, called BREEAM, is hoping to disrupt the United States’ green building certification world with its impending New Construction Standard Release in 2019.
