Updates on Miami ped bridge collapse

Posted by Strongbad (aka Rambler14) Mar 16 '18, 10:01

6 confirmed fatalities, which could increase as the day goes on

U.S. Senator Marco Rubio had tweeted Thursday night, “The cables that suspend the #Miami bridge had loosened & the engineering firm ordered that they be tightened. They were being tightened when it collapsed today.”

Miami-Dade County Deputy Mayor Maurice Kemp said, “We have not confirmed that there was a stress test. The key here is not to jump to conclusions, not to speak on speculations, but to work on fact. And that’s what we plan to do.”

As an engineer,
it looked very much like a stress test was going on according to the grainy surveillance video I saw on CNN.

And without a lot of facts yet,
this looks BAD for both the contractor and whoever was responsible for inspections, not as much for the designer.

Now is not the time to look at the engineering of bridges. Thoughts and prayers. -- nm - Mop Mar 16, 11:20
I keep reading it was some new construction technology that was moved into place as a unit, which makes construction much faster. Maybe they didn't - jnine Mar 16, 10:09 2
- IIRC that's how they build a lot of freeway stuff, preform, internal cables to stress it, move it into place over night. -- nm - Guinnezz Mar 16, 10:32
- LYC, here is a great video on accelerated precast construction. Not sure if this was used at this site or not. -- (link) - Strongbad Mar 16, 10:12 [youtube]
I am going to be interested in the final report, as I am curious if it was design or build at fault -- nm - crash davis Mar 16, 10:05 10

        at least you are smart like that. -- nm - groiny Mar 16, 10:31
  - “What do you mean we can’t take the supporting blocks away and just leave the bridge hanging in mid-air?” -- nm* - znufrii Mar 16, 10:18 1
    - L3 -- nm - SyrDragon Mar 16, 10:19
