Mailvox: Hultgreen-Curie, architecture edition

Has it ever occurred to feminists that perhaps there is a very good reason for the glass ceiling?
You have probably heard about the collapse of a pedestrian bridge at FIU in Miami today.  I was researching who the builder is, I stumbled across an article from yesterday celebrating the bridge’s construction.

 Key quote from the female engineer/project executive, Leonor Flores (speaking about teaching her daughter that women can go into STEM):

“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.”

Yeah, about that…
FIU pedestrian bridge collapses days after installation; police say multiple deaths, cars trapped.

If you think about it, what is this but an example of Merkel's Germany or May's Britain writ small? Or, to put it in even more brutal terms, Carly Fiorina's Hewlett-Packard....

Oh, my (stronger expletives deleted).

Engineering does not give a damn for sex. Sea, sky, and land will kill you just as dead either way. From my perspective, they either botched the design (either of bridge or the end supports), fabrication, or sabotage. And with a structural failure this soon after installation, the problem had to be blazingly obvious. Civil engineering isn't aerospace work, you can work with a comfortable factor of safety.

Blogger Noah B The Savage Gardener March 15, 2018 4:49 PM  

A single error doesn't cause a bridge collapse of this magnitude. There are normally all sorts of checks in place to help prevent this sort of mistake, but those procedures are only as good as the people carrying them out. Yay diversity!

Blogger AnvilTiger March 15, 2018 4:50 PM  

Apparently MCM built the bridge. The bridge was designed by a separate company, Figg Bridge Design. Initial assessment is that the horizontal part of the bridge (the span) did not fail, it was one of the support columns (a pier) that failed. What do you want to bet that they used cheap Chinese steel rebar in the support column? And that the supplied rebar will be found not to meet spec?

See here: http://www.theconstructionindex.co.uk/news/view/steel-producers-warn-on-chinese-rebar

"A significant – but unknown – proportion of the Chinese rebar sold in the UK contains boron in excess of 8 parts per million (ppm). Samples have been tested with boron at 30 ppm. The Welding Institute has now issued guidance that rebar containing boron in excess of 5 ppm requires changes from the normal welding techniques used.

The only way of telling which Chinese rebar contains boron is to test every single bar. Otherwise, fabricators cannot tell which welding technique needs to be used, experts advise. As such tests are not generally undertaken, there is thus a real risk that welded structures using Chinese rebar could fail, UK Steel warns."

Women should stick with being Interior Designers, even then many times it's too much emotion and not enough common sense. In my 20 years, all the engineers have been men, and common sense has been the theme throughout. It is idiocy to put someone in a position simply because they are a woman. Yeah, we can blame the Chinese steel all we want, the problem begins when you are hiring for the sake of diversity and not who can do the job the best.

Blogger Noah B The Savage Gardener March 15, 2018 5:03 PM  

It's unlikely that bad rebar was the primary cause of column failure. In concrete that's under compression, the rebar carries almost no load. The job of the rebar is to delay catastrophic failure, but it can only do so much.

Likely possibilities include bad design that wasn't thoroughly reviewed, substandard concrete placed that wasn't discovered by the testing lab, and catastrophic geotechnical failure.

Blogger FUBARwest March 15, 2018 5:05 PM

Interesting ... from the link "celebrating the bridge's construction" at the beginning of Vox's post, there is a "artist conception" drawing depicting a vertical central support beam with distributed supports. From the collapse photos I've seen there wasn't a vertical central support beam. Assuming it was part of the original design, it would not have collapsed like this. Like magic dirt ... magic concrete isn't magical.

One of the first things I learned in my studies to become an engineer was this ancient Hammurabi’s Law:
229. If a builder build a house for someone, and does not construct it properly, and the house which he built fall in and kill its owner, then that builder shall be put to death.
I believe this is one of the oldest laws known to history.

My first thought was China’s shitty steel, my second thought was shoddy (illegal) immigrant labor, then ‘minority owned’ business....
I didn’t even conisder female engineer until I saw this!

Not just "can" but "have to by law", in many cases.  If I recall correctly, the safety factor of cables for passenger elevators is something like 11:1.

Looking at this bridge, it's (it was) a relatively new style of suspension bridge which eschews the catenary arch for cables direct to the roadway, and requires the roadway to carry the horizontal component of the cable tension back to some point.  It looks like at least one end of the span was just resting on its support pier, so the force would have been carried by the roadway in compression back to the center pier where the cables anchor.  It's not immediately clear to me what could have failed in order to produce the pattern seen.

Every competent engineer knows the importance of using compliant materials. Every competent designer knows the importance of limiting 'artistic' design paradigms to the risk profile of a new construction. Every competent project manager knows the importance of checks and balances. As a petson who drives cars under bridges I don't care about sex or qualifications, I care about competence.

When it becomes more impotant for women to be in unsuitable STEM occupations than to check their own level of incompetence, disaster is inevitable.

College gender quotas in STEM = systemic decay from within. Something speciific will be blamed for the record, but I guarantee that there was more than one incompetent thing that led to this disaster.

This collapse is about a failure of accountabity. It has little or nothing to do with cheap Chinese materials. They'll always be there. Ever tried to check and balance a gender quota engineer if you're a man (or a lower-status woman, for that matter)?

Gender quotas in STEM are synonymous with decay. It's only a matter of how, where and when. Incompetent women will be well defended and twice as hard to hold accountable after the fact than before. Better to call them out before rather than after and save lives. Men do this all the time with each other.

Hold an incompetent woman accountable today and save lives!

@56 They hadn't even hung the cables yet. The part that collapsed was just half the span. They still had to build the central spire, place the other half of the span, and then hang the suspension cables.

Looks to me like the spans were constructed as pre-cast and assembled on site into a single unit before being placed on the abutments.

There are hundreds of things that could have gone wrong here.

Simple as it seems, good functional civil engineering on this scale isn't something that just any fool can pull off properly (as we're seeing).

Blogger Johnny March 15, 2018 7:10 PM  

The bridge is described as iconic, which means an original design, which also means there could be a design problem. But what is likely is the contractors were the problem. That would be the ones who took the bid or subcontract bids, not the low level guys who do the grunt work. They take bids and save money by cutting corners. If not watched a lot of them are given to that. This is such a routine problem that the people who have to be alert are the folks who put out the bids. You don't just turn it over, you have somebody familiar with design and materials inspect on a regular basis. If it is genuinely an all female or otherwise rookie team they probably lacked the experience necessary to supervise the contractors. That is where the cure has to be because you are not going to cure the contractors.

The other possible cure is to be selective in who you hire. That is apt to mean not taking the lowest bid. Even if the contractor is at fault, cure has to be with the people who put out the bids because that is what can be fixed. Yea old buyer beware in the building trades.

This is not the first time something like this has happened in Miami.

Several years ago, a nearly-completed parking garage at the Doral campus of Miami Dade College collapsed, killing four construction workers:
http://miami.cbslocal.com/2012/10/10/garage-collapses-in-doral-at-miami-dade-college/

The structure was torn down and rebuilt from the ground up.

During construction, a small portion of the new garage came down:

It has since been completed and is now in full operation.

Corruption in Miami is endemic. The city and the county governments have been controlled by the Cuban "exiles" for many decades now. (Fidel used to call them the "Miami Mafia.")

"The other possible cure is to be selective in who you hire. That is apt to mean not taking the lowest bid."

Public entities rarely have that option though. They can reject bids due to irregularities but are generally required to accept the lowest bid that meets all published criteria. People often complain about the lowest bidder building something, but the alternative is uncontrolled graft.

Much of the race-to-the-bottom dynamic can be stopped if honest, competent inspectors are provided on site full time. But most cities and private developers choose not to do this because it costs a lot of money, and they also know that contractors will raise their bids if they know that inspectors will actually prevent them from cutting corners.

You just had to drop the F word on me, didn't you? May God forgive me, but I hate that effing F woman. I was working at HP when she got the CEO spot. First thing she did is add the word "Invent" to the HP logo. Then she started firing all the inventors. Most jaw-droppingly cynical move I've ever seen.

She bought Compaq so that she could use "lateral transfers" from Compaq to dilute the established HP management structure, which was resisting her tooth and nail. There was nothing that woman would not do to destroy the culture of what had been one of the most innovative of the Silicon Valley tech giants. She acted as though she hated the company she was charged with leading...and I really think she did hate it. Maybe the reason for that was that most of the tech people were men, and management was pretty much white and male.

Under the F regime, there would be layoffs every three months. This in a company that had a proud tradition of never laying off people. After the first one, which gave the impression of eliminating some actual deadwood, who was chosen for elimination seemed to be completely random. See, it wasn't as though you could work really hard, get good reviews, and buy immunity to being laid off. It didn't matter what the quality of your work was. Essentially, the company was saying in the most direct and clear manner possible: "We don't care about you or your work. You are disposable. You are interchangeable. You are nothing.". It was pretty bleak, and had the kind of effect on morale and personal relationships that you can well imagine.

The timing of the layoffs strongly suggests that their actual purpose was to show "cost cutting" in the quarterly report. After the report was out, they'd hire more people--but not the same people. Cheaper people, like H1B contractors.

When they finally got to me, it was a relief. I was outta there. But the F name is still anathema to me, and I'm not alone. At least they aren't mentioning her as a possible presidential candidate any more. Considering how many people she antagonized (as in hundreds of thousands of HP employees), maybe that's a case of payback. I like to think so.

3. Why had they not installed the final supports?

Because the center support pier for the cables is not designed to sustain large bending loads.  You need to tension the cables on both sides at the same time.  It couldn't be done before the second span was emplaced.

2. Why were support cables "loose" in the first place?

See above.

1. Why stress test when there is traffic underneath?

Idiocracy.

The LiveLeak video does appear to show the reinforced concrete lower deck failing in tension, but that may not have been the triggering event.  Between the low frame rate and only partial coverage of the construction zone it can't be determined from that alone.  The failure site is suspicious, though; bending moments are highest at the center, not closer to the 1/4 point where the break appears to have occurred.

I'm betting that the vagineer didn't do a stress analysis for the incomplete bridge, only the ultimate state with all the support cables in place.  This is going to smash the "more women in STEM!" crusade.

Looks to have been a failure during post-tensioning of one of the upper diagonal truss members on the end that collapsed.

The tell-tale is the post-tensioning strand extending several feet out of it's conduit with the hydraulic tensioning unit still attached to the end.

If the strand or the anchorage thereof failed during tensioning, the structure would fail almost immediately in tension right at the midpoint of the member that the missing strand was loading.

What possessed them to undertake a high risk operation like post-tensioning while traffic was live under the bridge, only God knows for sure.

THAT is the decision that needs to be scrutinized most closely.

Structural failures during construction happen sometimes, especially when the design is new and edgy (IE poorly thought out and/or too close to the razor's edge), but nobody would have died here if they hadn't left the road open to traffic while they were doing this.

Figg was responsible for the design-build and noticed a crack during the tensioning process and there lead engineer left a voicemail on an FDOT machine acknowledging that a crack had developed in the span but apparently did nothing to mitigate the risk. Smoking gun.

Tension stressed concrete can wickedly and catastrophically fail so I'm not sure why the Figg engineers thought a crack appearing during tensioning was no big deal. Incompetence.

Correct. Unfortunately, FIU ("International" being an odd way to spell "Cuban" but hey) has made a big commitment / investment in teaching ABC techniques. Keeping the road open during construction is the whole selling point of ABC, so closing the road to do the work... well, closing the road is 100% guaranteed to make someone unhappy. Not closing it? Maybe we'll get lucky.

Also, looks like they didn't follow the design for moving it into position. They shifted the transporters to different support locations on the span and left off spreader plates. In particular, according to AvE's YT, the end of the span that collapsed may have been left unsupported right under the PT strand that failed while they moved it.

Anonymous Anonymous March 17, 2018 10:54 PM  

One of the post-tensioning rods failed. AveE has an excellent video about this.

So, they were stress-testing. And the bridge failed its stress test. That's cool - after all, that why tests are done. Why exactly it failed is not really the issue (chinese steel, bad design, misplacement of the installation supports, whatever).

The reason people died is that the area was not barricaded off.

The root of the failure here is the concept of an "instant bridge", the idea that something like this can be installed and good-to-go in a couple of days with minimal disruption to the area.

Well guess what? That works perfectly fine … until it doesn't.
