Academic: Miami Building Collapse an “Early Warning” of Climate Change

Guest essay by Eric Worrall

According to Visiting Lecturer in Sustainable Development Ran Boydell, The horrific collapse of the condo building in Surfside may be a warning of things to come, if we don’t reduce CO2 emissions.

Most buildings were designed for an earlier climate – here’s what will happen as global warming accelerates

Ran Boydell
Visiting Lecturer in Sustainable Development, Heriot-Watt University

Climate change will affect every aspect of our lives – including the buildings we live and work in. Most people in the US, for example, spend about 90% of their time indoors. Climate change is fundamentally altering the environmental conditions in which these buildings are designed to function.

Architects and engineers design buildings and other structures, like bridges, to operate within the parameters of the local climate. They’re built using materials and following design standards that can withstand the range of temperatures, rainfall, snow and wind that are expected, plus any geological issues such as earthquakes, subsidence and ground water levels.

When any of those parameters are exceeded, chances are some aspect of the building will fail. If there are high winds, some roof tiles may be ripped off. If, after days of heavy rain, the water table rises, the basement might flood. This is normal, and these problems cannot be designed out entirely. After the event has passed, the damage can be repaired and additional measures can reduce the risk of it happening again.

The tragic recent collapse of an apartment building in Miami in the US may be an early warning of this process gaining speed. While the exact cause of the collapse is still being investigated, some are suggesting it might be linked to climate change.

Whether or not the link to climate change proves to be true, it is nevertheless a wake up call to the fragility of our buildings. It should also be seen as a clear demonstration of a critical point: wealth does not protect against the effects of climate change. Rich nations have the financial clout to adapt more rapidly and to mitigate these impacts, but they can’t stop them at the border. Climate change is indiscriminate. Buildings are vulnerable to these impacts no matter where in the world they are, and if anything, the modern buildings of developed countries have more things in them that can go wrong than simpler traditional structures.

Read more:

I tried to find Ran Boydell’s staff entry on the Heriot-Watt university website, but his name didn’t appear in my search.

As for Ran’s claim about the building collapse being caused by climate change. We are used to climate scientists trying to opportunistically attach themselves to any recent crisis, to push their fear mongering. But in my opinion trying to exploit the Miami building collapse, before the investigation has concluded, while people are still searching for bodies, sets a new low for this kind of behaviour.

Look at the garage roof in the second link. Ripped out rebar everywhere. I looks likely they poured plaster instead of concrete.

This is much closer view of what we could see in all the floor sections which were exposed last week. The rebar ripped out on the underside. This view does seem to show the bar was deep enough, so this probably means they were using substandard concrete. Indeed I don’t see any hardcore there, it looks like very homogenous, fine grained mix. Strange.

I read an analysis in The Graun that argued that sea level rise “acceleration” meant salt water was rising up through the limestone foundations faster than expected and this was causing the rebar to rust and expand, making the concrete foundations crack and split.

They also mentioned that that part of Florida is subsiding at 2mm a year!

So come on, which is it, the salt, the water, or both, let’s have a decision here based upon a terrible tragedy resulting in the loss of life? I know nothing about structural engineering being a retired Chartered Structural Engineer (UK), however, I suspect a combination of water, salt, poor foundation design, poor construction, poor quality control on site, poor quality control off site, poor supervision by the authorising organisation, but a meagre 1.1 degree rise in globally averaged temperature over the last 150+ years I very much doubt had anything to do with any of it!!!

The only rebar I can see is hanging freely in the air because it ripped out of the concrete. Clearly something was not built correctly.

Look at the garage roof in the second link above. ALL the rebar is stripped out. The same thing can be seen in the floors exposed in the part which collapsed.

That is NOT how “steel reinforced concrete” works.

The rebar you see “hanging freely in the air” actually trances back, in almost every case, to the lower 1-2 inches of the concrete slabs comprising the floor/ceilings of the remaining standing structure. The central area of the total building (the portion that first collapsed) sheared away in a completely different manner from the “tower” that collapsed 2-3 seconds later: in that section one does not see into the various rooms as one does on the tower section. However, there is still evidence of the rebar being peeled away from the vertical surfaces, indicating that it was not properly buried in the interior of the concrete walls.

I agree 100% that this is NOT how steel-reinforced concrete is designed to be used in structural elements.

The entire AGW scam is a top-down creation. Black Swan author Nassim Nicholas Taleb describes these in his book Anti-fragile as fragile creations. Because they are top down built and thus is fragile. Being fragile, they can collapse easily when even mildly shocked with new information and better ideas
The Marxist Left has recognized this fragile feature of their Climate Scam. Thus they must suppress counter-evidence and also scientific critics bringing new data and alternative interpretations. i.e the Cancel Culture is born in this suppression.

Excellent comment, thank you Joel.

The global warming alarmists’ abysmal predictive track record:
The global warming alarmists have a NO predictive track record – they have been 100% wrong about every scary climate prediction – nobody should believe them.
The radical greens have NO credibility, make that NEGATIVE credibility – their core competence is propaganda, the fabrication of false alarm.
The wolves, proponents of both the very-scary Global Warming / Climate Change scam and the Covid-19 Lockdown scam, know they are lying. Note also how many global “leaders” quickly linked the two scams, stating ”to solve Covid we have to solve Climate Change”- utter nonsense, not even plausible enough to be specious.
Regarding the sheep, especially those who inhabit our universities and governments:
The sheep are well-described by Nassim Nicholas Taleb, author of the landmark text “The Black Swan”, as “Intellectual-Yet-Idiot” or IYI – IYI’s hold the warmist views as absolute truths, without ever having spent sufficient effort to investigate them. The false warmist narrative fitted their worldview, and they never seriously questioned it by examining the contrary evidence.

This is getting a lot of South Florida attention. One of Biden’s cabinet suggested sea level rise. NOPE.
The 2018 engineering inspection showed seriously deteriorating concrete from corroding rebar (thing is on the ocean, and they did not use epoxy coated rebar to prevent salt corrosion), especially under the pool plaza which also had an improperly designed waterproofing. And this morning, as the implosion crew was drilling to place explosives in the remaining vertical columns to take the remaining portion down, it was discovered that there is less ‘Tbar’ tying the remaining vertical columns to the foundation slab than the design had called for. At that time, rebar was super expensive.
-flawed design 1980 (flat rather than sloped waterproofing-no drainage)
-construction corners cut 1981 (bare steel, not enough steel)
-poor maintenance detected 2019 but deferred for cost reasons until mandatory 40 year building recertification.

Collapse just before overdue concrete repair was scheduled to start in July.
NOTHING climate related despite the nutty professor.

Though I can not find the video, a retired civil engineer, I believe, described a truly plausible scenario based on his career knowledge.

“Miami building failure.
Post tension flat slab concrete with internal cable failure at lower level. ”

Versus static slab construction of most other buildings.

Firstly, he stated he would never accept an engineering project of this style of construction because in the first place it’s cheap. Secondly, as he described it, this is a stack of cards construction where a weakness at any point in the cabling system for post tensioning creates a vulnerability in the Whole system.

The pool deck thing is a rational point of weakness and corrosion where the cabling is hidden internally and inspection difficult.

His final read was that there are many, many buildings that used this construction technique 40 years ago and they are All vulnerable. He referred to the many buildings in Florida and up the east coast and he finally stated that buildings of this type may become uninsurable. Yikes!

Engineers of this level of integrity keep the rest of us safe.

Except the pictures show this was not cable tensioned slabs. There are Miami Dade rescue pictures of the collapsed garage under the still standing west portion of the building clearly showing ‘columns punch thru shear where the garage slab simply fell leaving its inadequate slab rebar dangling out the sides of the column. Probably a secondary rather than primary cause. And may not be a single primary cause, rather two or three all mutually reinforcing.

Most concrete from the Roman era wasn’t anywhere near as consistent as our modern concrete, so most of it has long ago crumbled away. However, they noticed over a couple of generations that concrete made with a particular volcanic sand from the town of Pozzuoli lasted impressively well. This was due to anti-crack propagation properties of the material. Our entire concrete construction industry is cost optimized for a life cycle of about 200 years, rebar is readily available, and Pozzuoli sand or a synthetic equivalent would be more expensive than people generally would want to pay.

There is zero evidence that ground water intrusion (allegedly related to claimed sea level rise under the Climate Scam) led to that condo collapse. None. People claiming that are just making sh!# up to serve an agenda. Any academic who claims this, and should know better, is simply a liar.

What seems obvious to me is the structural slab underneath the condo pool was catastrophically compromised by a break-up/rupture in the pool plumbing and the pool itself that sent tens of thousands of gallons of poll water into an already weakened structure The structural slab and columns already had been noted with extensive rebar corrosion from what was likily a leaking pool for years. There are pictures of standing water in the pool pump-filter room under neath the slab that supported the pool. Chlorinated pool water easily leads to corrosion of rebar through cracks in concrete that had been noted but not repaired.

That inrush of pool water likely led to a slab-column punch through under the weakened corroded reinforced concrete. When the slab gave way, the entire side of that condo collapsed like an implosion demolition under failing columns to a impulse dynamic loading.

Most houses built around 1900 used open slab limestone with a cement layer inside. It could work well for centuries if here wasn’t a lot of ground water to leak in.

In the neighborhood I lived in in St.Paul all the houses from downtown out were built that way. Every 10 blocks or so, 1 mile, was the distance for each new development extension. You can walk down any street going towards the river and see the change- free laid limestone slabs, cut slabs or block, smallish square precast concrete, bigger plain hollow blocks similar to current concrete block, next the the blocks were decorated to imitate carved rock, then modern concrete block, and then each house used a somewhat different foundation style ending up with various poured concrete foundations.

As long as the groundwater was controlled everything worked well.

Nothing at all unusual about a building collapsing straight down.
When the first column gives way, the load spreads to the next which also collapses, then the next collapses and pretty quickly then have all given way.
This process can occur in 10’s to 100’s of milli-seconds.

“Nothing at all unusual about a building collapsing straight down”.

but some interesting fluid dynamics goes on in the process, as rubble & debris start acting like a viscus liquid.

The twin towers was a prime example of a progressive collapse, each floor collapsing onto the one below increases mass & velocity resulting in a percussion effect several floors below each last collapse (the pictures of which lead to conspiracy theory’s of controlled demolition ). There is also a horizontal cushion of air expelled from between each floor at high velocity taking light debris out sideways, some of which go up & then back in towards the building center as there is now an area of low pressure in the space the building occupied.

Great video.
Thank you.

I worked for the Manhattan engineering company that designed the internal systems of the building.

Each floor is attached to a square pattern of columns with brackets
When one floor falls on top of the floor below, then two floors fall on the next floor below, etc.

The plane mostly evaporated (aluminum vapor) upon impact on the building. Heat of impact.

In a short time, resulting fires weakened the floor connections to the columns, etc.

From images accompanying the 2018 engineering inspection, it was. The vertical concrete support columns were all exposed to salt spray entering the partly open parking (foundation slab) level. They all had severe spalling from rusting bare rebar (which swells) from salt intrusion from sea spray. We see the same thing in Chicago freeway vertical concrete; the salt there comes from seasonal winter road salt so is not year round like Champlain Towers South.

We live directly on the ocean on the twelfth floor in Fort Lauderdale, about 50 miles up the sand from the disaster. We have to clean salt spray off the massive hurricane proof balcony glass facing the ocean about once a month, from salt spray when waves break on the beach during the every afternoon onshore breeze.
Our building used coated rebar. The vertical support columns are all exposed in the three story garage structure. There is ZERO spalling since completion in 1997.

It’s not actually from Heriot-Watt, but from an Australian activist and architect who works in the UK. To qualify for the title of ‘visiting’ lecturer he probably only gave a couple of lectures on his favourite subject but believes the connection to a University gives him more credence. The University may well be completely unaware that he’s using their name in his activist pieces.

I wonder how much delay all the various “closed-due-to-COVID” planning/permitting offices contributed. I know the department that hears appeals to King County, WA property tax assessments has been closed for over a year. In the meantime, property owners must pay tax based on the latest appraisal. No idea how backed up they are, but “about a year” would be a reasonable guess.

The kind of repair work the Surfside condo board were planning to do requires dozens of permits.

July 4, 2021 11:58 am

I read somewhere that the condo building had been sinking 2 mm a year, on those smallish concrete columns that were holding it up. That apparently also didn’t have enough rebar as per the original plans. I don’t know how far the concrete columns went down into the limestone ‘rock’, but any limestone is susceptible long term to erosion from water. If the pool had been leaking down into the ground below the condo and was slightly acidic, then a good possibility that the limestone starting rotting out allowing the building to shift slowly over time until something snapped. Not a sinkhole, but just eroding limestone without the basic strength to hold it up. Nothing to do with any minimal rising sea level, which would be alkaline pH anyway. Just natural rain water drainage which has an acidic pH would also contribute to the limestone decay.

I saw a video yesterday taken from the building next door. It was a stream of water pouring into the garage level of the building about 20 minutes before it collapsed.
Looked to me like a water main that had broken.
My guess is that whatever settling was occurring, had started to speed up.

One of the eyewitnesses (now missing and presumed dead) was on the phone with her husband when this started to happen. She told him the building was shaking and that a ‘sink hole’ had opened on the pool deck below their unit just before the phone went dead (collapse). That at least means part of the pool deck slabs collapsed into the parking garage below. Whether it means the below ground slab pilings had also collapsed into a subterranean ‘sink hole’ (support piling failure) is not (yet) known.

The 1997 landslip at Thredbo ski lodge, New South Wales:
Eighteen bodies were recovered and one survivor was rescued from under debris more than 60 hours later. Subsequent investigation found the cause of the landslide to be a leakage from the water main leading to the saturation of the fill embankment on the road.
Unless investigators at this Florida event have confidently eliminated this water/colloid/liquefaction mechanism, it might be fruitful to include it among possibilities. The topic is comparatively understudied in engineering and in geology. Geoff S

Not an engineer but can speak to that. Depends on the concrete PSI loading (a function of how much cement, sand, and crushed stone in the mix—more cement and less sand gives a higher psi crush strength—and the steel rebar design.

Specific example. Our building is 27 stories from ground level, so 28 from the lower lobby/bottom garage foundation slab, itself tied into numerous large concrete/rebar columns sunk down about 80 feet thru sand into the limestone bedrock. (Same as a newer, lower height complex just completed about a half mile south, also on the beach).
So we are over twice as high as Champlain Towers South. The vertical columns are exposed in the garage, and partly exposed in the lower lobby and lockoff storage rooms of the tower itself. They are all the same, about 1 foot wide by two feet long (rectangular), 10 foot high to next floor (each floor slab is also tied to the column by extra ‘Tbar’ set in an extra concrete floor thickness “box” about 5 x 5 foot square and about 8 inches thick around the column itself, integral to the ‘ceiling’ slab, done in one pour. The columns are not regularly spaced because of the building shape, but average about 15-20 feet apart.

So ‘spindly’, but good enough for a 28 story structure to withstand a 150 mph Cat 5 hurricane (the rating of our balcony glass and sliding doors, themselves set in 1/4 inch thick extruded solid aluminum frames anchored every two feet into the floor/ceiling concrete slabs.

Champlain Towers was built pre-Andrew, so not to our newer codes, and less than half as high. It would have been ‘spindlier’. Think it was rebar corrosion forcing concrete spalling that was not repaired, rather than basic structural engineering, that caused the partial collapse.

This was interesting. Included portions of a building report. As you suggested, spalling had been identified as a problem.

Reply to  Rud Istvan

McDonald made general claims of beach sand and of salt water used in some foundations 40 years ago, which increases spalling due to rebar corrosion.
Also 40 years back there were much lower standards for the quality of the steel used in rebar, as well as the amount of reinforcement.
If Champlain was even partially inundated with salt water during Andrew or any subsequent weather event, or even badly implemented drainage of salt spray, that would also affect corrosion in reinforced concrete.

It was affected by climate but not caused by climate change.
1) The building is built on a sand bank that once had vegetation (eg. mangrove swamps) & close to salty water reduces the life of typical concrete structures. Always has been open to the storms & hurricanes of a similar level, no significant change.
2) The building had a basement that was dug several metres below the sea level when it was built, adding a few centimetres of average MSL would not have changed that.
3) Several levels lacked or damaged water sealing so more water was in contact with the concrete & moving through it. This includes from the pool level into the basement, water through doors/windows (lacking seals/drainage or later damage of frames).
4) The rebar had no protection against rust. Modern steel reinforcement bars can be coated in plastic to keep out water (costs more). Rusting steel expands, cracks the concrete & eventually fails.

If this building was constructed >5km from the sea with basement & footings above sea level & proper waterproofing & drainage then it would have lasted >60years.

By David Brown| In Sinkhole RepairSinkholes
Mapping Florida’s Sinkholes: Understanding the Sinkhole Threatcomment image

Sinkholes can form anywhere in Florida, but the highest activity level occurs in west central Florida because of the karst limestone environment. There are several influences that increase the risk of sinkhole activity such as long-term weather conditions, heavy acidic rains, and drought-like conditions.
The regional map on the right depicts sinkhole locations that have been reported since 1954 by the Florida Geological Survey Series No. 110. It does not show all sinkhole activity in Florida, but you can get a generalization of how widespread this problem is.

Sinkhole Zones in Florida

  • Zone 1 (Yellow): This region consists of exposed or thinly-covered carbonate rocks. Broad and shallow sinkholes are common in this area. Cities in the zone 1 region include Miami, Coral Springs, Hialeah, and Hollywood.
  • Zone 2 (Green): This region has permeable sand that varies in thickness from 20 to 200 feet. It mainly consists of small cover subsidence. Zone 2 cities include Fort Lauderdale, Port St. Lucie, and Orlando.
  • Zone 3 (Blue): Zone 3 has cohesive, low-permeable soil that forms abrupt collapse sinkholes. Cities in zone 3 include Tampa, Tallahassee, and St. Petersburg.
  • Zone 4 (Pink): This region consists of deeply inter-bedded carbonate rocks and cohesive clayey sands. Sinkholes are uncommon in this region, but collapse and small subsidence sinkholes can occur in shallow beds. Cities located in zone 4 include Jacksonville and St. Augustine.

Sinkhole formation has accelerated over the years. They are commonly created by extended droughts, heavy rainfall, land development, water pumping, and construction of retention ponds. Sinkholes in Florida can range in size small to large. Some are large enough to swallow homes, roads, swimming pools, and buildings.
Not only does sinkhole activity destroy structures, but they also pose an environmental concern. The carbonate rocks, which are present in sinkhole formation, provide direct access to all types of pollutants such as fertilizers and pesticides. Oil and gasoline also channel directly into the sinkhole. Despite all the problems sinkholes produce, they are a natural part of the ecosystem.

Know the Common Signs of Sinkholes in Florida
As a homeowner or business owner, it is important to know the common signs of sinkholes in Florida. Most sinkholes give early warning signs before they create become a serious threat. Look for the common signs of sinkhole activity such as:

  • Cracks in interior joint areas
  • comment imageCracks in stucco or exterior block
  • Sticking windows and doors
  • Yard or street depressions
  • Separations, cracks, and gaps in concrete
  • Wilting plants
  • Neighbors with sinkholes
  • Actual cavity forming
  • Foundation cracks
  • Settling foundation
  • Sloping floors
  • Ceiling cracks
  • Loss of pool water

If you notice any of these signs, give us a call. We can inspect your issue to see if it is a sinkhole and repair it if necessary. We offer sinkhole repair for the residents of Florida. Our services include compaction grouting and void filling.

  • Compaction grouting: This is designed to stabilize loose soil. It is a fast settling method that uses polyurethane foam that is injected into loose soil. As the foam expands, it compacts the soil.
  • Void filling: This is another sinkhole repair method. It involves filling up spaces and gaps underneath the concrete. We use a high density, lightweight material called polyurethane. It is injected into drilled holes. It expands as a foam, covering the area in seconds.

Propaganda is SO much fun to write!! The infamous “SOME” are “SUGGESTING” “MAY”.

NO mention of data. NO reference that links to any actual data. ALL the reporting is quite specific(unusual) that the building was 8 years late for inspection. Almost every report points to gross short cuts that had been taken during construction that effectively eliminated long term protection from corrosion of the steel, the strength of the concrete, and effective foundations.

The are also hints that the design, construction, and double checking of the building were not done completely. The style of construction did not have a long history of successful results.

The results they suggested based on the known facts are simply silly.
“But in my opinion trying to exploit the Miami building collapse, before the investigation has concluded, while people are still searching for bodies, sets a new low for this kind of behaviour.”(Eric Worrall).

Mr. Worrall is entirely correct in calling out the speculations(not facts) about the construction or circumstances of the building. “Climate change ” had nothing to do with it- not enough for tenths of a degree in temperature to have any effect.

I have designed several large industrial structures in Miami-Dade. I can tell you that we design with redundancy. Reinforced concrete design has always required sizing members so as not to fail in a brittle catastrophic manner. The failure mechanism presents the distress long before collapse. So consequently these catastrophic failures are extremely rare in the US.
However, drive a vehicle with a high yield device down into the underground parking garage next to an interior column, and you have a problem. And it’s not an environmental one.

Amongst the above-floated fluff from author Ran Boydell is this: “Whether or not the link to climate change proves to be true, it is nevertheless a wake up call to the fragility of our buildings.”

This is a ridiculous statement on its face. The Surfside building collapse got all of its news coverage for the basic reason that such a collapse is so extremely rare, not being associated with an earthquake, a violent storm, flooding, fire, terrorist attack, etc. (my comment here is certainly not meant to diminish the tragic loss of life and grief and suffering associated with this building collapse).

What the video and photo coverage of the remains of building clearly tells me is that the steel rebar—that was supposed to be used to “pre-stress” the concrete to obtain specified design strength for the main structural material (reinforced concrete) used throughout the building—was incorrectly positioned within in concrete floors/ceiling and wall slabs. In an extraordinary number of visible locations in the standing structure, as well as some of the collapsed concrete slabs, one can see evidence of the rebar rods being located within an inch or less of the surface, NOT in the middle zone of the 4-6″ thick horizontal and vertical concrete slabs, as it should have been to develop maximum structural strength.

Furthermore, even including the Surfside building collapse, what is the total percentage of 40+ years old concrete “high rise” structures that have collapsed in such a fashion over, say, the last five years? I willing to bet it is less that 0.005% . . . and that’s what Boydell refers to as “the fragility of our buildings”???

Climate change has absolutely nothing to do with improper design or improper construction.

There is no way a properly-designed building should have totally collapsed in a matter of 12 seconds. What happened was a chain-reaction (or domino-effect if you prefer). Modern building designers are supposed to ensure there are enough reserves of strength throughout the building’s key structural components to prevent small, localised failures from propagating right across the building. So if a column breaks, the load it was carrying can be transferred onto the adjacent columns without them breaking too.
It is clear from press photographs that some of the columns were seriously lacking stirrup links. Such links are absolutely essential to a column’s strength.
Also, the building seems to have used a form of construction called “flat slab” – i.e. just columns and slab – no beams. But years after they became fashionable, someone found a flaw in the then-prevailing theory of flat slabs. So the early flat-slab buildings had (and still have) woefully inadequate rebar in the slab-to-column connection. This fault can be seen in some of the press photographs of the Chaplain South Tower.
That building was a death-trap on the day it opened.
