Actually, it is clear from this version of the Morabito plans where the "new slab drop panel" detail was planned. Note 10 on S2C-1.0 defines these locations with a box with a dash line. If you look at the driveway area near the west end of the site, you will see where this condition is...
That lawyer seems to be presenting themselves as an expert in geotechnical engineering and offering theories which imply some degree of certainty, with no citations to actual experts in the field.
"Absent an act of terrorism, the most likely cause of the building’s collapse was either a...
I had two points about over reliance on the direction of noise in the forensic analysis, but since Spartan covered the first I only have one.
The physical evidence suggests a ground level failure originating at the garage. If a ground level column failed at the exterior face of the building...
Spartan5 - they're not there. The morabito plans only called for removing the topping at the pool deck, repairing whatever cracks they find, and then installing a new topping (and waterproofing). They called for some more significant structural alternations along the driveways into the at...
Solid analysis by Building Integrity. Would like to learn more about his calculations showing that the pool deck was designed at 100% capacity with dead load, and whether that considered additional loading from the topping layer, sand layer, and pavers, along with planter beds containing water...
Insurance companies doing what insurance companies do best. They love taking your money, but always find ways to not pay out their own. I don't see how the insurance companies can refuse to cover the engineer at this point, until the cause of the collapse is better identified. Even then...
Based on the deformation near the door frame in the unit 711 Ring video, I think it's very likely that anyone in the 11 stack, including 811 could have had difficulty opening their front doors. We do know that 111 and 611 got out so maybe it was some but not all doors.
Pretty clear that the...
Not that I think this was part of the cause, but it's been reported that the Town stopped the construction at one point because the developer didn't have permission to build the penthouse, and it violated local ordinances (which were later changed to appease the developer). From Wall Street...
I think you are looking at the uncollapsed portions (which eventually collapse) behind the front face that is in the process of collapsing. This may include the lower roof (between the elevator shaft and penthouse) pitching down as well as the 13th floor passageway to the penthouse condos.
Buildings are built next to each other every day, in every city, in every country, across the world. This includes buildings with deep foundations in urban settings, with next to zero clearance. It's unrealistic to look at this as some unique situation that caused the collapse. While I don't...
I'm here due to need for answers on something that just isn't supposed to happen. Conventional "wisdom" has been that concrete fails slowly, shows distress, cracking, deflection, etc. before catastrophic failure. I've been checking back to see if new evidence drops.
The slow trickle of...
But we can go, the building fell down because the design made it fall down if the deck collapsed.
It may be the "it's just a pool deck" thinking that led to the maintenance not being taking seriously for 40 years. If one of the condo units had cracks, water, and rust dripping into it, they...
Not sure if anyone tried this already, but I tried to create the same angle in Google Earth as the security camera footage of the collapse. It's pretty clear that the middle part of the building has already dropped about one story at the beginning of the video.
The engineer probably made one set of plans for everything and then were later asked to divide the project up into different bid packages, that's how non-relevant specifications end up where they are not needed. It's also a good way to end up with overlaps or scope gaps. The intent though in...
Thermopile - I think this is a topping they added to the flat structural slab to introduce slope towards the pool deck drains. The problem with that in addition to the added load, is it left a cold joint between the sloped topping slab and flat structural slab, which would be a nice place for...
