You are looking at concrete being poured higher than any building has ever reached and they are nowhere near the top.

80 floors, 320 m, still only 1/3 of the way up.

This building will reach one full kilometer into the sky.

The Burj Khalifa held the record for 15 years.

The Jedha Tower will make it look like a medium-sized building.

Standing at the base and looking up stoer, you cannot see the top.

The construction workers up there are invisible from down here.

Every 4 days, a new floor.

1,000 workers on site.

The fastest concrete pour at this height in human history.

thumbnail

Concrete pumped 800 m vertically, a distance that has never been achieved anywhere on Earth before.

Then nothing.

In 2018, the cranes stopped.

The workers left.

For 6 years, this building stood frozen, going nowhere.

January 2025.

The cranes moved again.

The world’s most ambitious building, abandoned for 6 years, came back to life.

The site is so large that workers use vehicles to travel between areas.

A construction city built around one impossible tower.

before a single floor went up, they spent a year building underground.

And what they built underground is extraordinary.

Coral reef limestone beside the Red Sea.

The worst ground possible for a kilometer tall building.

The cores came back full of voids.

Gaps where a billiondoll foundation would find nothing.

Every cavity grouted shut before a single pile was driven.

Hole by hole across 3,200 m.

Bower drilling rigs from Germany, 1.

8 m wide, 105 m deep into Coral Reef, 270 piles, each one deeper than the Washington Monument is tall.

105 m deep.

That pile goes further underground than this building is currently tall above ground.

Each cage built in 30 m sections, lowered in sequence, one sitting on top of the last.

4,400 tons of steel in the piles alone before a single floor existed above ground.

Concrete poured from the bottom up, displacing the fluid above it.

One continuous fill.

The Red Sea soil eats steel.

A cathodic protection system wired through every pile fights it permanently.

270 pile heads exposed.

Now, the platform that connects them all, 3,650 tons of rebar.

Workers tying every intersection by hand across an area bigger than a football pitch.

Six layers of rebar 5 m deep.

The strongest foundation ever built for a building.

18,260 cub m of concrete pushing against the perimeter forms.

The pressure of a dam wall.

The pour starts at night.

Cooler air.

The concrete generates its own heat.

It needs help staying controlled.

18,260 cubic meters of concrete poured without stopping.

That is enough concrete to fill seven Olympic swimming pools.

72 hours without stopping.

Stop it and you get a cold joint.

A weakness buried forever.

Too much heat and it cracks.

Workers controlled the temperature inside this concrete for 28 days.

One year of work.

Invisible forever under everything that comes next.

The hexagonal core goes up first.

The spine that carries every floor, resists every wind, supports 1 kilometer.

The jump form climbs automatically.

Workers ride it up.

It has been climbing since 2013.

Core walls 1.

5 m thick at the base.

85 megapascals, twice as strong as standard concrete.

85 megapascal concrete mixed on site, pumped immediately, poured and vibrated within 90 minutes of mixing.

One floor every four days.

The workers feel the platform rise beneath them.

They don’t see it happen.

Three wings, three jump forms, all climbing, all connected to the core at every single floor.

Every floor, the wall angle changes, the rebar changes with it.

Every floor is different from the last.

Every batch tested before it leaves the plant.

Substandard mix rejected.

No exceptions.

350 bar of pressure.

Pushing concrete up 800 m through a pipe the width of your arm.

This pipe carries concrete from here to 800 m up.

The concrete arrives at the top.

Still workable.

Two floors below the core.

The slabs follow.

Install.

Pour.

Strip.

Move up.

Never stops.

Post tension slabs.

Steel tendons stressed after the pour.

No beams needed.

Faster, thinner, stronger.

Each tendon stressed to 200 tons.

Locked.

The slab permanently in compression.

Each floor slab poured in a single day.

Laser screeded to 3 mm flat.

The floor someone will walk on forever.

Formwork stripped after 7 days.

Moved up.

Installed again.

The same equipment used 150 more times.

12 hoists running simultaneously.

Three tons each.

The supply chain feeding 1,000 workers at height.

Four cranes climb with the building, bolted to the core as it rises.

700 m still to climb, climbing a tower crane inside a live building.

One of the most complex operations in construction.

Monthly at 300 m, wind forces that would topple a conventional building.

The three wings were shaped to stop it.

The wings split the wind vortices.

The building sheds wind instead of fighting it.

Shape is the solution.

No outriggers, no belt trusses.

The wings are the structure.

Simpler, stronger, faster.

320 m up, tying rebar in desert heat, red sea below.

Same work, higher every week.

45° of heat.

Concrete mixed with ice and chilled water to arrive.

Workable 800 m up.

Squeeze a 10 cm cube of this concrete.

It takes 85 tons before it breaks.

Nothing weaker could carry this building.

Workers start at dawn before the heat peaks.

Jeda is still sleeping below them.

Every bag, every tool, every water bottle hoisted 300 m.

The logistics are as hard as the structure.

The walls thin as the building rises.

Less load at the top.

Every meter of wall designed for exactly its load.

Steel embeds cast into every wall positioned to 5 mm before the concrete covers them forever.

Floor 50, 200 m.

Already taller than most skyscrapers, still 1/5 of the total height.

Construction doesn’t stop at sunset.

Night shifts pour in the cooler hours.

The tower rises in the dark.

November 2017.

Saudi Arabia’s political earthquake.

Key figures detained.

The crane stopped the next morning.

The contractor bin Laden group was tied to the detained individuals.

Within months, Pure work stopped.

A thousand workers left the site.

The crane stopped turning.

63 floors, 252 meters.

Then nothing.

6 years frozen.

Cranes rusting.

Sight empty, going nowhere.

6 years of Saudi sun and Red Sea salt air.

The concrete didn’t deteriorate.

Not a single floor failed.

September 2023, 14 contractors invited to bid the world’s most ambitious abandoned building coming back.

Same contractor, $1.

9 billion contract to finish what they started 7 years before.

Every existing floor inspected before one new pore, 63 floors of abandoned concrete, all passed.

January 2025, cranes moved.

Workers poured floor 64.

Six years of silence ended in a day.

Same mix, same method, same workers.

The pores erased in a single continuous paw.

Floor 64 to floor 80.

January to December 2025.

One floor every 4 days.

Faster than before the pause.

Old concrete bonding to new.

The critical question.

Core samples confirmed it.

6 years made no difference.

workers, rebar, formwork, concrete.

Repeat.

That is what building the world’s tallest structure looks like.

February 2026, floor 100.

Confirmed by the structural engineers.

The pace is accelerating.

Pre-fabricated rebar cages hoisted complete.

One lift replaces 40 individual bar placements.

That is why a floor takes 4 days.

800 m of vertical concrete pumping.

A world record broken every single day.

The workers pour.

These hands are building the tallest structure in human history.

5,000 pairs of them.

The workers on this site come from 30 countries.

Most earn $20 a day.

They are building something that will stand for a century.

500,000 cub m of concrete.

80,000 tons of steel.

Truck by truck, floor by floor.

80 floors, 320 m.

taller than everything around it and 680 m still to build above that.

At 1,000 m, the building sways.

The tuned mass damper moves opposite.

Cancels it.

Nobody feels it above the occupied floors.

The wings stop.

The core continues alone to 1,08 m.

Pure concrete reaching up.

The top 200 m are structural spire only.

No floors, no occupants.

59 elevator shafts, five double-deck cars, 10 m/s.

The fastest passenger elevators ever built.

Elevator rails aligned to 1 mm over 500 m.

Workers do it by laser.

There is no other way.

Top floors pouring concrete.

Bottom floors installing pipes and wiring.

30 floors of fit out simultaneously.

Glass panels installed from inside.

The only safe method at this height.

800 kg each.

Floor by floor.

Floor 157 644 m.

The world’s highest observation deck.

Currently 324 m above the highest pore.

Every pore sampled.

Every cube tested.

Every batch verified.

Then and only then the next floor goes on.

Above 40 km per hour, the cranes halt automatically.

The sensors stop them before anyone gives the order.

45°ree heat.

Workers rotate every two hours.

Ice vests at this height.

Heat stroke means 30 minutes to evacuate.

Every worker clipped to a lifeline at the perimeter.

The wind at 300 m doesn’t care who you are.

This clip is what stands between a worker and 300 m of air.

On this site, clipping in is not optional.

It is the single non-negotiable rule above floor 10.

The cranes visible from 20 km at sea.

Sailors navigate by them.

The highest construction lights on Earth.

Rebar pre-fabricated at ground.

Hoisted complete.

One lift replaces 40 bar placements.

The reason the pace holds.

Every 30 floors, the wall steps thinner.

The formwork adjusts.

The rebar changes.

The hardest pour on every cycle.

A 30 m steel balcony at 600 m.

No building has ever canlevered this weight at this height.

At 1 kilometer, you can’t evacuate by stairwell.

Refuge floors, sky bridges, express elevators, all being built in now.

Every 30 floors, a refuge level, fireproof, pressurized, independent power where people wait if it goes wrong.

100 floors, 400 m.

The Burj Khalifa at 828 m.

Now the target above them.

Their fathers poured the Burj Khalifa.

These men pour the Jeder Tower.

Their children will know what that means.

600 sensors embedded in the concrete.

Strain, tilt, settlement.

The building reporting its own condition in real time.

Every sensor in this building tells the engineer something.

At 1,000 m, you cannot guess.

The building tells you what it’s feeling and you respond.

25 mm of total settlement allowed.

After 12 years of construction, 10 mm used, the foundation is performing perfectly.

Workers tying rebar on the 85th floor.

Right now, the highest active construction floor on the planet.

Today, every floor tapers, every facade panel a different size.

157 floors.

No two panels identical.

The pump pressure increases as the building climbs.

The target, 1,000 m of vertical delivery.

Never done before.

Shift handover at 300 meters.

Every problem passed person to person.

The Red Sea from 320 m.

Workers see it every day.

Future occupants will pay millions for that view.

59 elevator shafts, eight stairwells, every service riser, all rising simultaneously inside a single hexagonal core.

5,000 workers per shift.

Home to Jedha.

Back tomorrow.

same floors, higher every week.

Every one of those workers knows they are building the tallest building on Earth.

You can see it in how they walk.

There is something in building something that no one has ever built before.

Every morning the cranes catch the sun first.

The highest point of any active construction site on Earth.

80 floors done.

77 occupied floors to build.

Then 200 m of spire.

The hardest half still to come.

1,08 m.

The first building in human history to cross 1 km.

This is what it looks like being built.

Three times the Eiffel Tower, twice the Empire State.

180 m taller than the Burj Khalifa.

644 m.

World’s highest observation deck.

On a clear day, the curvature of the earth is visible.

204 seasons rooms.

Floors 19 to 27.

The workers pouring those floors.

They will never stay in them.

The penthouse at 600 m.

One apartment.

A 30 m balcony over nothing.

The most expensive address on earth.

270 piles.

105 m deep each, 38,000 cub m of concrete, all invisible, all carrying everything above.

Every project we build starts with one question.

What should we bring to life next? That answer is yours.
