Saudi Arabia’s Jeddah Tower was engineered to reach an unprecedented 1,000 meters into the sky, but restarting construction after a 7-year pause has exposed a critical structural engineering challenge.
For seven years, construction halted abruptly at Floor 63. During this extended shutdown, exposed rebar and concrete surfaces were subjected to extreme coastal weather, intense desert heat, and high-salinity air from the Red Sea. Now, as new concrete pours resume and engineers prepare to stack an additional 50 floors onto this aged joint, questions arise regarding structural integrity, cold joint shear strength, and differential settlement.
Resting on an innovative piled raft foundation over porous coral rock formations, the kilometer-high skyscraper operates on razor-thin tolerances—where uneven foundation settlement of just over an inch could severely stress the entire concrete core. Can modern forensic engineering and structural remediation ensure the safety of the world’s tallest megatower, or does building directly onto a 7-year weathered core pose an irreversible mechanical failure risk?
In this deep-dive engineering analysis, we explore:
The Floor 63 cold joint and saltwater corrosion mechanics
Structural challenges of pouring fresh concrete onto aged, weathered surfaces
Deep foundation engineering on Red Sea coral bedrock
Wind vortices, vortex shedding, and lateral shear forces on a 1-kilometer megatructure
How mega-scale construction restarts handle hidden structural defects

In Bible times, there was a mighty hunter in opposition to Jehovah God. It was under his direction the Tower of Babel began. He wanted to make a tower so tall that its top will reach all the way to heaven. God suddenly made them speak different languages. Since they could no longer understand one another, they stopped the building work. 😊
PS, I sit corrected! I apologize to my Arab friends! Should have known it was an American and all for a freaking title!!! And whoever built the one in Dubai is Evil cause this means that they knew before they built it that there was no sewage infrastructure! Y'all did know that, right… no sewage infrastructure, fact check me! They flush the skyscrapers toilets at night in dump trucks and go to the ocean or the desert!
I think it's a combo of Texas Tea, Petrol dollars, the heat and the too tight turbins on their head that messes with the frequencies and wi fi affecting their cognitive function or here in the Texas Panhandle, Stupidity with a side of Pride!😂
ha ha, WEST is colapse …in DA slow motion-LOL
When it begins to tilt who will tear it down?
Kaboom !
Turmbau zu Babel. Sie bauen auf 'Sand', nicht auf Werte.
Que veut prouver l'Arabie Saoudite par la réalisation de de la Djeddah tower.
Les etudes viennent de l'occident
La technique de réalisation vient de l'occident
Donc quel prestige peut tirer l'Arabie Saoudite ? Est ce prestige d'avoir l'argent ?
La Norvège a plus de fond souverain,mais ne cherche pas un prestige construit par les autres.
Nous devons tous nous rappeler la leçon de la légende de "Haroun" ,qui voulait acheter la vie éternelle,et on lui a conseillé de lui faire remplacer sa tête par un tête en or et de les avoir cru ce fut sa perte ,une fois coupé,sa tête en or ne repris pas la vie.
C'était la " legende de la richesse de Haroun"
⅓ SPIRE?
SMD! THAT'S BS.
GFY GUYS!
This is such a vanity project.
Why don't they just all go in the bathroom with a tape measure!
WTF are they thinking about?
All these Saudi mega projects are the same BULL. Nothing more than yet another vanity project FFS.
So funny. So stupid. So useless. So sad.
Record heights replace quality and safety for the egos of the builders. Shortsighted fools.
And It’s Failing ? The only thing failing is this laughable AI crap video. 😂
More money than sense. What goes up, must come down!
These projects are built for clout by idiots with more money than brains.
All these buildings should include demolition plans.
What is the point?!?
wesh ! halal !
If the goal was to have humans waste a huge chunk of their labor and resources, then this is a valid design.
HAS ANYONE FIGURED OUT THE ISSUE OF A ((( FIRE ))) IN A BUILDING THAT HIGH — THEY COULD NEVER EVACUATE THE PEOPLE FAST ENOUGH — CAN YOU IMAGINE THE ELEVATOR SYSTEM THAT HIGH
AND THE FIRE SURGING UP THE ELEVATOR SHAFTS –THE STAIRS WOULD BE JAMMED .At some point, somebody is going to make a modest building with a very high spire. Say, 50 stories, and an aluminum spire.
We (u.s.) have spire envy. Face it we (u.s.) are yesterday's news. the Arabs do not cut corners. These structures have a invisible purpose. They are mosque or temples reaching to the heavens.
Personally, I'd only count height accessible without special equipment, eg, street clothes. A mechanical floor counts. A spire does not.
I guess that 'spike' will be carbon fiber.. a real lightening rod..
More money than sense or brains. Both of these Arab skyscrappers are on a ticking clock. They will both collapse. The Burg is already on the way. There will be no rescue from these buildings. In a fire, you are trapped if the elevators fail and the stairwells are blocked.
Hubris built the towers. Pride goeth before a fall. The ruins of these "civilizations" will be astonishing and very sad.
If you were the lead structural engineer on this project, would you have approved pouring 50 new floors onto that 7-year weathered seam—or is continuing construction simply not worth the risk? Let’s hear your take below
