What Went Wrong At Surfside Collapse?

On July 6, 2021, Informed Infrastructure Editorial Director Todd Danielson interviewed Steven M. Baldridge, P.E., S.E., LEED AP, president of Baldridge & Associates Structural Engineering (BASE), which he founded in 1995. A leading engineering firm in areas of high natural risk, the company now has offices in Hawaii, Chicago, Florida, Guam and India.
The topic of the interview was the deadly June 24, 2021, failure and collapse of the Champlain Towers South in Surfside, Fla. Visit www.informedinfrastructure.com to learn more.

    Yes it's ok ..I believe the building sinking and being maybe a deck slab and floor attached may have applied downward pressure on the deck causing punch in the planter area which was in poor condition in 2018 🙄

    I heard it mentioned elsewhere that every time it rained or there was a storm sea water got on the pool deck. The deck absorbed the water (even though some of it was drained out). When it all evaporated, it always left the salt which would attack the concrete and the rebar over the decades. Add in the weight of more continuous water on the deck, cars, planters and possibly over-weighting of some apartments above with large marble tile walls and floors and granite counter tops, etc. and the collapse seems inevitable.

    You bring up so many potential paths to failure it is very frightening. If one column can be removed for a building failure then how many holes need to be drilled and how much explosives used. My understanding is the whole building was made out of concrete and rebar. They stopped rescue work Saturday and 24 hours later the building was down then cleaned up. How fast could a team go in the basement and drill some holes. The building swayed could that have been an explosion? What if a car or other vehicle damaged a post could that have started a collapse?

    2:30, wrong. Evidence is not on the bottom of the pile. It’s on top. The columns are on top of the slabs and that means all of slabs slid down all of the columns, which then fell on top of the slabs. Inherently unstable flat plate design. Similar design buildings are in danger of collapse as their rebar ages. If only one joint fails, the whole thing collapse just like this one. This is not the first to collapse- many have. 60% of collapsed in Mexico City were this cheap and dangerous design.

    Aged rebar? Rebar that has been flexed too many times or rebar that has rusted, or rebar that hasbeen asked to do more than it can because of missing concrete, but old rebar?

    By Leon Wechsler Architect: The one and only reason this building collapsed is lack of concrete beams under the pool deck and the same in the building portion that collapsed. However this will never be brought up in the inquiry, because Structural Engineers are not ready to expose this main reason, because many of them design the same thing in buildings that were not built with post tension cables in the slabs.

    I tell you what happened... Stolen rebar by the constructor, very thin pillars, weak pillar beam junctions, no concrete shear walls in the structure (except for the elevator wall). How in the world a column can punch through the pool deck slabs which practically carry no weight. This is unheard of and unimaginable. Decades of old godforsaken concrete piers with rusty rebars and whatnot literally over the sea just stand indefinitelly. This is called a royal theft and murder. It's twin must be demolished ASAP and the unit owners should sue the constructor for a compensation. Period.

    Good point about the collapse of the pool deck being pretty ridiculous. No other videos have mentioned that, but there has been discussion of standing water on the pool deck contributing to the weakening there, and discussion of water damage evident on the ceiling of the garage under the now collapsed building.

    ​@@davesmith5656 Water normally has no power over the pool deck. There are so many flexible leak proofing mortars to apply the tiles. With the usage of proper material, sloping and drainage it's the easiest thing to make it water proof. It's definitelly a construction fault. I mean really... This kind of chain reaction yielding a total collapse of the whole structure is possibly unheard of in civil engineering.

    Developer Nathan Reiber used his own money in the project's early phases. He faced crazy-high materials costs and was constantly worried about his bottom line. When his capital ran out - the project stalled, leaving unused construction material exposed to the elements, while he returned to Canada to seek more funds. By this time, two Contractors resigned from the project, citing Reiber's reluctance to stick with the plans and skimping on rebar and concrete quality/quantity. He was also known to hire unskilled, non-union labor(see crane collapse video) and even hired a cut-rate Architect, who was previously suspended for structures that failed during Hurricanes. Some say he even failed to do proper soil analysis and foundation piles were not as the drawings specified. Codes in 1979 were quite lax. This project should have never happened. Reiber was initially in Florida enjoying his retirement as a Canadian tax expat, when suddenly envisioning a luxury beachfront community, while on a walk one day. Everything was hastily planned and executed. Reiber was obviously blinded by the dollar signs, which he eventually received when the last unit sold($23,000,000/total). Unfortunately, he is no longer available to answer for anything, as he passed in 2014.
