Imminent failure mechanism for this structure. because the tower that came down, came down on itself. it s almost like a controlled demolition. and, you know, there are several ways that can happen. the column can fail. punch and shear could have happened. the foundation could have given way. we also need to check the original design. was this structure well-designed? folks might say that the building has been standing for 40 years. so was the i-35 bridge. it stood for 50 years, and coll collapsed. those are the things that i would check. this engineer s report was craig out for more investigation into the building in 2018. professor, you know, you re right about the bridge. and you re right, as we looked at that video, we saw the video of this structure, this condo
States. but also understand, that s an uphill climb. doj has to show there was purposeful discrimination behind these lawsuits. they do a good job in the complaint. but again, you don t have anybody out there saying let s pass these laws so we can discriminate. you have to look at the stats and read between the lines. but it s really important that doj is taking up this fight. every election can t be like this one. oh, my gosh, this is going to be nuts. i don t know have i have the stomach for it. thank you, gentlemen, i appreciate it. a 2018 report said there was, quote, major structural damage. three years later, the building is a pile of rubble. we ll look at what could have caused it, that s next. plus the nfl comes out during pride month, the nfl comes out during pride month. i ll explain. you have to see their new ad. - had enough? - no. arthritis. here. new aspercreme arthritis. full prescription-strength? reduces inflammation? thank the gods. don t thank them too soon.
Of this report being out there. and these were not the only concerns, by the way. there have also been concerns about nearby construction, some people in the building say they felt shaking in the building which alarmed them. we ve heard reports of creatks n the building. does any of that definitely have to do with the collapse? absolutely not, but these are things that have to be looked at closely by investigators. tom, thank you. i want to bring in a professor of structural engineering at drexel university, thank you so much for joining us, professor. you took a look at the reports that raised major concerns about the major structural damage to the concrete slab below the pool deck and cracking and crumbling of the columns and beams of the parking garage. professor, does that offer clues as to why this building came
A miami-dade government structural and electrical assessment of any building 40 years old. according to the condominium association attorney, the building had multiple inspections and was in the process of extensive work which would have cost $15 million. structural engineer jason borden examined champlain tower just last year. i saw typical things we see in buildings, cracks in the stucco facade, i saw deterioration in the concrete balconies, cracks in the plaza level. those are all things we re accustomed to seeing. that s why our job exists. any cause for alarm in what you saw? in what i saw, no. reporter: the lack of alarm is sending chills through residents who live here and beyond. voluntary evacuations for the champlain tower s sister building and a rush to answer
Down? the clue it offers is that the engineer should have been given access to check the interior of the building, the slab, which he never had access, for some reason. it showed that deterioration was going on. but he did not check the main towers and check the slab/column connections. this building is a flat slab construction. so punch and shear, where the column punches through the slab, that s a common failure for these types of structures. if he had been given access to check those column connections to the slab, we would have known whether those were badly deteriorated and whether punch and shear was going to be an
