A devastating 6.4 magnitude earthquake rocked Taiwan on Saturday, February 6, killing a total of 116 and injuring many others. All but two of the deaths were caused by a collapse of the 17 story tall Weiguan Junlong (Golden Dragon) tower, the only high rise building to collapse in the city.
As crews have searched the area and initial investigations into the collapse have begun, they have discovered empty tin cans inside structural concrete beams. As crazy as that may sound, the reason those cans were there in the first place might be even crazier. A structural engineer told CNA, a Taiwan news channel, that, prior to 1999, use of cooking oil cans in concrete beams was actually not even illegal and were used to make the beams look bigger without adding much weight, for aesthetic reasons. Cooking oil cans. You read that right. The Golden Dragon tower was built in 1983, so the presence of the cans isn’t technically supposed to be a problem. Rebar was also found bent to 90 degrees, instead of 135 degrees, which increases the risk of the rebar loosening in the event of an earthquake.
However, on Wednesday, February 10, Taiwanese authorities did arrest the developer and two executives of the company that originally built the tower, even though the companies that built the structure are no longer in business. According to CNN, the three people arrested will face charges of professional negligence resulting in death.
The video below, by TomoNews US, gives a pretty good rundown of the factors that caused the collapse.
Scissor lifts are on most typical construction job sites and they’re an often overlooked hazard. Too often, liberties are taken with the lifts that create unsafe conditions, which can cause injuries and deaths. OSHA recently released the results of their investigation of 10 fatalities and 20 injuries involving scissor lifts and released their findings in what the organization refers to as a “Hazard Alert.”
If you’re into heights, then China may be the place you need to be. The country recently unveiled the world’s highest and longest glass bridge and, as scary as many tourists may find that, it was way more dangerous while it was under construction. New footage of another construction site in the Laowang Monutains is giving that bridge a run for it’s money.
Since Construction Junkie was conceived in 2015, we’ve seen a lot of construction equipment flip for some really stupid reasons. Like this crane, this other crane, and this third crane dropping a bulldozer. Those are just some of the ones caught on video and they should be enough to convince you not to go out of your way to do dangerous things with a crane.
A portion of the Skagit River Bridge, located in Mount Vernon, Washington catastrophically collapsed into the water below after a semi hauling an oversized load clipped a cross beam in 2013. Luckily and amazingly, no one was killed by the incident, but 3 people were taken to the hospital for minor injuries as several cars fell into the river. It took over 3 years to determine a cause and the report states that there were several causes. First, below is security camera footage of the collapse, uploaded to Youtube by newschannel500, in which you can see just how quickly the collapse happened.
Cranes are a staple of many construction sites throughout the world, but they’re susceptible to damage caused by sudden bursts of high wind. Winds were blamed for the collapse of the New York City crane collapse that killed one man and injured 3 others in 2016 and again for the devastating crane collapse in Mecca, which killed over 100.
Much like the stories above, a crane collapsed last week in Dubai, UAE, after sudden heavy winds burst through town.
Tragedy struck a Florida construction company last week after 3 construction workers passed away while working underground below a newly paved road. Another volunteer firefighter is in critical condition, and possibly in a coma according to WSVN Miami, after entering the manhole trying to save the victims.
No matter how fun demolitions and demolition videos might be, there’s an inherent danger to performing them that cannot be overlooked. Just last year, a different parking garage collapsed during a demolition in Houston, Texas, which landed on one of the excavators performing the work. Thankfully, no one was injured in that collapse, but it could have been much worse.

When construction sites are safer, then productivity increases as well as profits. More construction safety means less time lost due to accidents, lower insurance premiums, and less money spent repairing damaged equipment.
Jobsite pressures, such as time crunches and monetary issues can quickly tempt otherwise good people into making some pretty poor decisions. There are also others who use their construction business as a front for other illegal activities. Many people were arrested for a variety of reasons in 2016 and the list below should serve as both a reminder and a warning for those considering making bad decisions.
