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.

I’ve mentioned this several times before, but the single greatest thing technology companies can do for the construction industry is to allow cross-platform integration. That’s essentially what construction is at its core, anyway, a bunch of different entities working together for a common goal. Autodesk’s BIM 360, which already integrates 60+ different softwares into its platform, has recently added NoteVault to its list.
Arizona’s cost of living is 3.5% below the national average, according to MERIC, which helped them jump about 7 spots in the rankings after adjustment. There are two professions ranked in the top 10, including security and fire systems installers at #2 and solar panel installers at #5. The lowest ranked professions in the state are insulation workers at #40 and crane operators at #38.
When we’ve talked about construction robotics in the past, it’s mostly been about really large machines working on exterior structures, like this brick-laying robot, or this self-driving track loader. A technology institute in Japan is busy working towards bringing robotics to the interior finish side of the construction world with the development of a drywall installing robot.
Last week, we shared some newly updated Trenching and Excavation safety information from OSHA, which was part of their priority goals for 2018. Those updates included a public service announcement and updated online resources. The administration has just announced the update of their National Emphasis Program (NEP) on trenching and excavation safety, which features a period of education and prevention outreach.
A construction crane that was working on a highway widening project in St. Martin Parish in Louisiana collapsed onto the adjacent roadway last week, injuring one driver.
The first state to be on the right side of our countdown is the Centennial State: Colorado. It received it’s nickname after becoming an official state 100 years after the Declaration of Independence was signed.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
Earlier this year, it was announced that reducing injuries and deaths caused by trenching and excavation collapses would be a priority goal for OSHA in 2018. The administration planned to achieve this through increased inspection rates, public service announcements (PSA), updating online resources, and creating a better public-private partnership. Recently, OSHA made good on their promise to issue PSAs and update their online resources.
