Since the horrific FIU bridge collapse last Thursday, there has been a lot of speculation on how exactly this catastrophe happened, based on pieces of information learned over the past few days, as well as a couple grainy videos of the collapse. It’s going to be a long time before investigations into the true causes are determined and all the dust surrounding impending lawsuits clears, but for now, we have one very interesting Youtube video explaining a plausible cause of the failure.
For those who don’t know AvE, he’s a Canadian YouTuber known for his colorful language and tearing apart tools to see what makes them “cooch” (one of the many words he’s made popular amongst his viewers). In other words, he’s got an engineering mind with the mouth of a sailor.
He recently got his hands on some preliminary plans for the FIU bridge and believes he’s found the “smoking gun” for what caused the collapse. In the 16 minute video below, he’ll take you through a few of the most interesting drawings and details of the structural system. He analyzes the images and videos from the scene, in addition to performing what he calls a “homebrew experiment” to illustrate his point.
This is obviously just one theory, but it appears the most plausible so far. What do you think of Ave’s theory?
If you couldn’t gather from above…be warned that there is foul language in the video, if you’re averse to that.
Bluebeam Revu is a very popular PDF markup and collaboration tool for the construction industry. Each year, the technology company updates its flagship program to adapt to how their customers currently use the program and makes changes to increase their productivity. Bluebeam recently announced the launch of Revu 2018 and we have a breakdown of all of the changes.
Overall, Oregon was in the middle of the pack with regards to hourly wage for the 25 construction professions analyzed, with an average ranking of 18. However, the Northwest state has the 3rd highest cost of living, according to MERIC, as it costs 31% more to live there versus the average state.
The construction industry has never been one to freely share information without charging a fee. That’s changed slightly recently, with some major players willing to provide useful tools and information to help us become better. For instance, we recently shared that Procore has released hundreds of free continuing education courses on their education platform. Another useful site we’ve found recently has shared dozens of toolbox talks to help your team on the jobsite learn about safety.
[guest post] The reality is that construction workers, who already face hundreds of hazards just by working in the industry, are also often at risk for becoming injured or ill due to contact with wildlife.
Back in 2015, engineers at MX3D made a huge announcement: they were going to 3D print a steel pedestrian bridge on-site. That plan has been altered slightly in the nearly 3 years since the announcement, but the group recently completed printing the full span of the bridge.
Maryland is ranked 7th in highest cost of living wages according to MERIC, which dropped their overall hourly wage ranking from around 20th to the 48th ranked state.
Demolitions by implosion seems like the easiest way to knock down a structure, but there is so much preparation that goes into it that even the slightest mistake can have a huge impact. When smokestacks are demolished correctly, it can be a thing of beauty, like when these two silos in Scotland hit each other midair or when this asbestos filled stack was precisely demolished to fall into a pool of water. Things didn’t go so smoothly for demolition crews in Denmark last week, however.
It should be obvious that formal safety training is extremely important to running a successful safety program on any construction site. The most common route for construction employers to train their staff is through OSHA 10 and OSHA 30 courses, but, in the past, it was pretty confusing to determine who was actually authorized to teach the courses and where to find them.
[guest post] Spring is here and before we know it, summer will follow. In both seasons, weather conditions can present dangers to construction workers. Without education and preparation, workers may find that they are seriously ill or injured during work.
