US Dept. of Labor (OSHA) PDF reports of construction accident incidents 2

Oof... toughing reading these. But it's for the best that we do.

It'll be interesting to see Millennium Tower entered one of these days...

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

I believe the listed projects all involved OSHA violations and or worker injuries. Millennium Tower may not have injuries -- yet.

There is a highly disproportionate number of these incidents taking place in South Florida.

I think they're not listed until the report is complete.
And I mildly disagree that the "Hair Hang Act" at the Ringling Bros. and Barnum & Bailey Circus is a construction incident, but it's still interesting.

bones - I noticed the same thing.

The Glulam pedestrian bridge really jumped out at me for some reason. Maybe it's because I was tasked with some (much smaller) glulam ped. bridges when I was just starting and I felt completely lost. But seeing how neglecting one basic property of wood/glulam design can cause such catastrophic results - isn't there a quote attributed to Hardy Cross to the effect of 'a structure is a series of connections held together by beams and columns"? What with all of our delegated connection design in steel and the minimal attention paid to connection design generally (I think we learned what a bolt was in my undergrad) it's not all that surprising that some of these accidents are happening.

That glulam bridge was a pretty audacious design. Lot's of highly engineered intricate novel connections. I can see how they have lost sight of bigger picture (yet basic) issues like notching beams. I just finished designing dozens of novel high capacity timber connections and was definitely in microscope mode most of the time. Having unrealistic timelines and pressure to "just get it done" doesn't help either. You need that time at the end of a project to re-examine everything with fresh eyes, not just breathlessly emailing the drawings to the client 30 seconds after printing to PDF at 4:59 on a Friday.
