Miami Bridge

[cda]

Appears in the news shots, there is a center support,

But do not see it in the move::

So I wonder if this is final design::

And more temporary support should have been in place?

"""The main span across SW 8th Street is held by 2 supporting towers, and a cable system for bracing that had not yet been installed."""

Lack of those towers and the tensioning that was done may have upset the spans balance.

Though MCM is owned by five brothers, a lot of people one rung down the ladder from them are women. Some of the construction workers are even women. How ironic is it then, that earlier this month, MCM was slapped with a lawsuit for hiring “incompetent, inexperienced, unskilled or careless employees.” Fox reports:

The company is building an expansion to Fort Lauderdale International Airport and a worker there was injured when a makeshift bridge collapsed under his weight, the lawsuit says, according to the Winston Salem-Journal.

Leonor Flores, FIU alumna, and MCM project exec says her number one priority when building bridges is to make sure they look pretty. Nothing else matters:

“It’s very important for me as a woman and an engineer to be able to promote that to my daughter because I think women have a different perspective. We’re able to put in an artistic touch and we’re able to build too.”

No. You can’t build things. The bridge collapsed for no other reason than terrible structure. Though the death toll is currently at six, police say that the number is likely to rise. But no, let’s talk about how strong and powerful these women are. This company prides itself on how many women they hire, saying that it’s a big step towards gender equality. That’s not working out so far, is it?

There’s a reason you don’t hear about women in construction; they’re not very good at it, and quite frankly, they don’t want to be. Women in MCM promote feminism when it’s convenient; when everybody’s looking tough and ready to conquer the world in their construction hat. But when their projects fail, and lives are lost, everyone wants to focus on all the men in the company. Nobody, not them or the mainstream media is talking about all these women and how they dropped the ball. None of them want to take responsibility, and that makes both the media and these women spineless cowards.¹

The collapse starts on the left, where there is a construction crane and active work happening. There was a triggering action in the work being done.

Completely agree. Looking at the frames at 7:72 and 7:78, the collapse appears to either have been right where they were working, or where the support they are working on bears to the right.

Here's an overly-long summary of what was described on the Reddit engineering subforums. Short version: post-tensioned cables failed first, probably due to being overstressed. source of stress is not known, but one potential source might be due to how the prefab bridge was supported during transport.

Warning, foul language.
