Has anyone actually seen the 2020 Morabito Consultant report referenced in the letter the head of the condo board sent out to the residents in April of this year? I’ve seen the original 2018 report posted in this thread, but several news stories keep referencing the newer report. NPR has some...

I played with the street view you linked to, and you can definitely see that several of the lower balconies were in poor repair on their undersides:
IR Stuff, I thought it was interesting that the NTSB made such a point of company policies against using PED’s while driving too. In this case, while the deceased driver was using a personal vehicle he was also distracted by playing a game on his Apple-owned PED. Since the crash occurred while...
The NTSB held their hearing yesterday. I haven’t had the time to watch the full 3-hour presentation, but the board had some very harsh words against Tesla, the NHTSB and Apple (for not having a company-wide policy against using personal electronic devices while driving).
Link to full meeting...
Since the prior thread has been closed, I thought some might be interested to learn what the outcome was for the gas company involved in the disaster. Record 53 million dollar fine and the company, Columbia Gas, is to be sold. For some reason, residents just don’t feel safe leaving Columbia Gas...
The pilot was IFR rated and recently retrained, but interviews with other pilots he flew with indicate he did not have experience flying in fog or cloudy conditions. You may be qualified AND current and still simply lack direct experience with those conditions. It doesn’t take very long for...
The NTSB released a preliminary report on the crash today. Short but does give some new information. Specifically, it looks like the engines were working at the time of the crash and the blades were rotating at the time of impact. Looking more and more like the pilot may have become disoriented...
Vance, consider what might have happened if they had closed the road after the March 15th meeting.
They would also have suspended the retensioning of the PT bars in 11, since putting up a crew would have been unsafe. If the PT bars had NOT been retensioned it is possible that the bridge could...
JStephen, yes, Figg was the designer for the new Harbor Bridge. Yes, the bridge is under construction, or was until Texas DOT suspended the build.

Reading through FIGGs analysis as well, Vance. I find it supremely unconvincing.
They state several times that MCM/BP did not accurately inform them that the cracks in 11/12 and the pier diaphragm we’re getting worse, and then they admit in the details that they knew this information but were...
Vance, I’ve spent all day trying to find the dimensions of member 12 that FIGG used for their models, and I’m having no luck confirming that what MCM said in their analysis is correct. However, I think we are on the right track about the pylon/member 13 pour happening prior to the backspan. If...
Vance, I’m trying to find the calculations you asked for in the reports. The dimensions of member 12 are mentioned in MCM’s analysis of the collapse but I am looking for confirmation of this in FHWA report. Starting at page 76, they go into FIGGs use of computer modeling to analyze forces and...
The model matters because the model FIGG used for their calculations, the simple span, overestimated the dimensions of member 12 and ran the calculations as if the backspan was partially in place. FIGG never properly accounted for the forces in the structure when the main span was supported with...
I’ve been following this forum since the day of the collapse but since I’m not in structural or construction, so I’ve never thrown out any comments. However, I’ve been an NTSB follower for many years and have watched at least a hundred of these board meetings. I’ve never seen anything like this...
