Get it up.

Narrator: In chicago...

[ speaking spanish ]

Narrator: ...A team
of elite engineers

Is embarking on
an epic endeavor.

Man: All right!
We're coming down!

They're building
a super tall skyscraper,

One of the most luxurious
residential towers in the world.

It's going to be just
an architectural icon.

This one is special.

Narrator: The team must battle
fierce arctic-like winds...

Thompson: If you told someone
what goes on up there,

You wouldn't believe it.

Good there, james.

Narrator: ...Extreme vertigo...

Hold on, rodrigo.

The higher we are,
the more of an adventure it is.

Narrator:
...And an uncompromising

Deadline...

Should've been done
yesterday.

Where's my hammer?
Who stole my hammer?

There is no time to come back
and fix anything.

Narrator: ...To add this
colossal new centerpiece

To the world-famous
chicago skyline.

This skyscraper ranks
in a league of ambitious

New engineering wonders

That are bigger, faster,
taller, and more advanced

Than anything
ever constructed before.

This is the inside story of
the extraordinary challenge

Of building these giants.

Chicago.

150 years ago, this city
gave birth to the skyscraper.

Today, nearly 3 million people
live here.

Demand for living spaces

In the busy city center
exceed supply.

Chicago developer kris schwengel

Is devising
an innovative solution.

Since I was a boy,
I wanted to build big,

Tall buildings,
high-rises, skyscrapers.

It was the vision
from the beginning to create

Not just a series
of buildings

But to really create
a neighborhood.

Narrator: This family-run firm
plans to build their most

Ambitious skyscraper
to date in downtown chicago.

Schwengel: It's the biggest.
It's the tallest.

It really is kind of the apex

Of everything that we've been
trying to do out here.

Narrator: Their vision
is to construct

The 1,200-foot-tall vista tower.

Three giant towers make up

This stunning
cloud-piercing skyscraper.

One of chicago's busiest roads

Passes beneath
the central tower.

Further up, 15,000 custom-tinted
windows form its curved sides.

A shimmering facade
that mirrors the lake.

A five-star hotel
occupies the base,

While 393 luxury apartments
make up the higher levels.

The tallest tower soars nearly
1,200 feet above the lake below.

These penthouse levels
give unrivaled 360-degree views

Of the stunning city skyline.

♪

Building this soaring
triple-tower skyscraper

Won't be easy.

On the vista's north side
is the river

And chicago's
famous multilevel wacker drive.

They plan to build their tower
right over this street.

We have a public street
going right through the project.

Narrator: The lower level
of wacker drive

Will make a right turn and pass
directly underneath the vista,

Creating an unprecedented
construction challenge.

The roadway has basically
a 70-story building above it.

Narrator:
And as the team builds higher,

They'll also have to brave
the windy city's

Notoriously wild weather.

The weather we can't control.
[ chuckles ]

Narrator: This is the plan.

Crews will begin by sinking
124 concrete support pillars

Called caissons
110 feet into the ground.

Hundreds of trucks will pour
100,000 cubic feet of concrete

On top to create
two giant foundation pads.

The team constructs central
cores for the two outer towers

And builds a thick concrete
wall to join them together.

This giant super core makes
all three towers stronger.

Workers make each new floor
a different size

To create
the tower's wavy profile.

Crews need to complete a floor
every three days

To stay on track.

Finishing crews will then
wrap the building

In 700,000 square feet of glass

To create a stunning addition
to chicago's skyline.

Work begins in August 2016.

We have a wide site that sits
right on the river in chicago.

Narrator: Although on paper,
this prime riverfront

Real estate looks like
a fantastic spot to build on,

In reality, it's anything but.

Schwengel: We're actually on
what used to be lake michigan.

This is completely reclaimed
land from the chicago fire.

The fire happened in the city,
and they took all the debris

And just pushed it
into the lake.

Narrator: In 1871,
the great fire

Completely destroyed chicago.

Following the disaster,

The chicagoans
banned wooden buildings

And cleared the burned remnants
of the old city into the lake

To make way for
the world's first skyscrapers.

High rises like the famous
home insurance building

Rose up, built from
the new materials of steel

And reinforced concrete.

♪

Today, kris' team must build
on top of the debris

From the chicago fire.

They need to sink the foundation
caissons 110 feet below ground

Just to reach a solid base.

Roughly a 12-story building

That we go down to found
the building on bedrock.

Narrator: As the building rises
up from its gargantuan

Foundations, the team faces
their next big challenge

Constructing this
triple-tower skyscraper.

The 30,000-ton central tower
will need to float 50 feet

Above the busy
wacker drive turnoff.

This requires some complicated
engineering.

Like most skyscrapers,
the two side towers

Rely on a solid concrete core
for their strength,

Huge central pillars
that rise from the foundations

And support the building's
extraordinary weight,

But the middle tower
is different.

Because it sits above a road,

It can't have a central core
running to foundations below.

Instead, a thick concrete wall
which begins above the road

Runs the width of the building
from east to west.

This binds the middle tower
to the cores on either side

And channels its weight
to the other towers' foundations

Through a solid central spine.

This creates one unified
megastructure,

Bridging the roadway beneath.

Schwengel:
We have a wall here anyway.

We're just making the wall
a little bit thicker

And tying
the two cores together.

Narrator:
The tower's unusual core design

Creates a huge bonus
for its residents.

We have the added benefit
of having more open planning

For the residents
of the building,

Giving bigger floors,
bigger units, more usable space.

Seven, four, 90.

Narrator: The vista's concrete
skeleton will weigh over

100,000 tons.

Head of concrete kevin morley

Is in charge of every wall
and floor.

[ indistinct chatter ]

His crews are on
a punishing schedule

Of completing one entire
floor level every three days,

A difficult target
given chicago's

Notoriously
temperamental weather.

Morley: The level of difficulty
is pretty extreme

With the weather.

It's very unpredictable.

I eat, sleep and look at weather
24/7, so that's our life.

It basically
drives our schedule.

Narrator: Chicago is exposed by
lake michigan to the east

And the great plains
to the west,

Creating some dangerous
swings in the weather.

-I got the hull there.
-It could be calm all day,

And we get a storm blow through
that could have

80-, 90-mile-an-hour winds.

It could change in five minutes.

You don't know.

♪

Narrator: In chicago, workers
building the super tall

Vista tower need to make
quick progress

Before the winter weather hits.

You got to be prepared for,
you know, whatever type

Of weather comes in.

Narrator: But the vista's
complex shape isn't helping.

Unlike the flat-sided towers
of the last century,

This groundbreaking design
curves inwards

And outwards as it rises.

This creates a problem
of where to place

The columns
that support each floor.

Schwengel:
In a traditional building,

These columns would go
straight up and down.

Now, as you can imagine,
the building gets

5 or 6 feet wider here.

This column would be
in the middle of the room.

We didn't want that.

Narrator: If the buyers
are paying millions,

They expect unobstructed views
and no awkward columns

In the middle
of their luxury living spaces.

The skyscraper's engineers
devise an innovative solution.

♪

20 concrete columns support
each floor of the vista tower.

They transfer the massive weight
of the building downwards,

But the building's wavy profile

Creates a construction
challenge.

If they stack the outer columns
directly on top of one another,

They would pass through
the middle of some of

The most desirable apartments,
taking up valuable floor space.

To overcome this, they plan to
line up the outer columns

With the edge of each floor.

Every floor,
they shift by 5 inches,

Walking out over 5 feet,
then shifting inwards again,

Following the building's
distinctive curved profile.

Morley: It's not part of our
nature to building stuff

Leaning, build it at an angle,
build it out-of-plumb,

But in this case,
out-of-plumb was the way to go.

Narrator: Head of concrete
kevin morley is in charge

Of the team building
these so-called walking columns.

They start by assembling
huge panels into a mold,

Being careful to offset it
from the column below.

Man: Okay!

Schaack: Five inches was sort of
the maximum we could step out

To make sure that the load

Transferred correctly
through the building.

Oh, I got a 5/8.

Narrator: Once each column is
poured, there's no going back.

Hey!

So every measurement
has to be perfect.

Okay!

If two columns
don't overlap enough,

It could bring
the whole floor down.

Morley: Well, your typical
buildings that, you know,

Go vertically straight up
are looking pretty simple

After you go through
something like this.

Narrator: Once the 20th
and final mold is filled,

Another floor is done.

It takes 16 months
for kevin's crew

To reach the top floor
of the skyscraper's first

And lowest tower.

The construction crews
make rapid progress.

Let's take it
back in, okay?

But with just over
a year to go

Until the first residents
move in,

One of the worst winters
on record strikes chicago.

A freak weather system plunges
the city into a deep freeze.

In the past two days,
we were getting, you know,

20 below zero.

Up at the top, we're at
minus 10 degrees from that,

So it's negative 30 up top,
and chills are negative 60.

[ man shouting indistinctly ]

Narrator: Vista's hardened crew
is used to the cold.

Coming back in!

But this is out of
the ordinary.

Thompson: This is what we're
dealing with right now.

The wind is driving the snow
and ice at 45 degrees.

These are our edge
protections, our netting.

But actually,
there at the bottom,

You'll see me
kick it here now.

That's probably
an inch solid of ice.

Morley: I've never experienced
this extreme-cold temperatures.

The guys get out
of the man hoist,

And their eyeballs
start freezing up,

And the guys with, you know,
full beards right now,

They have icicles
hanging off their beards.

Narrator: The team still has
20 floors of the skyscraper's

Tallest tower to construct.

Man: Move in!

But with the crew's safety
at stake,

Kevin is forced to
shut the site down.

[ man shouting indistinctly ]

It's beyond the beyond,
pretty brutal.

♪

♪

Narrator: As the vista tower
soars farther into the sky...

...A record-breaking
winter storm hits chicago.

Severe ice halts construction
for five days.

[ indistinct chatter ]

Eventually, the spring
sunshine breaks through.

[ indistinct chatter ]

And even though the top
of the tower

Is still bitterly cold,

This tough crew can roll
with the punches.

Man: Number one!

As the tower rises, the team
now faces a new challenge --

The wind.

Morley: We're seeing
a substantial increase in winds,

And as we get higher,
we're expecting those winds

To keep increasing.

Narrator:
At over 1,000 feet in the air,

The winds hitting the finished
tower will be so strong,

They will cause this
slender skyscraper to sway.

Building moves.
All buildings move.

It's important that they move.

Narrator: Engineers design
all high-rise buildings

To have some sideways movement
to cope with wind forces.

But too much movement could
cause problems for residents.

Thompson: The building is
going to sway back and forth

At its natural frequency.

You could potentially feel
a sense of motion sickness

Because of the acceleration
of the building.

Morley: Some of these
older buildings, older designs

From years ago, you could
actually feel it within.

You could see the water
in the toilets moving.

Narrator: To counter the tower's
motion, the vista's design team

Has turned the idea
of sloshing water

Into an ingenious solution.

At the top of the highest tower,

Engineers will build
giant concrete boxes

Filled with water
called slosh tanks,

Six in total.

When high winds
push the building one way,

The water in the tanks starts
moving in the same direction

But more slowly.

This delay in the water's motion
means its massive weight

Ends up traveling in the
opposite direction to the tower.

The construction crew will also
install giant steel paddles

Inside the tanks, suspended
inches from the bottom.

The water pushes against
these paddles,

Exerting a stabilizing force
on the tower,

Evening out the wobble
caused by the wind

And keeping the building still.

♪

Kevin and his team get to work

Shaping the enormous
concrete tanks.

Morley: Tanks are, you know,
60 foot tall,

And they're essentially
concrete walls

On the very top
of the building.

Man: All right!

Narrator: They use giant
16x25-foot wooden panels

To build the mold
for the wall of each tank.

Morley: So now you got extra
walls that you're doing

At the very top
of the building,

And it's something
that you do not

Want to be dealing with up
at those elevations,

Which is your deadliest winds

And your deadliest
weather conditions.

Narrator: Moving the giant
slosh-tank panels is

A dangerous job for
crane operator mike femali.

It's very challenging.

You don't want to wreck
the crane.

You don't want to wreck
the form work.

You don't want to hurt anybody.

You guys ready?

All right.
Coming up.

If they get caught
with the wind,

They're just like giant sails up
on the very top of the building,

And once they take off,
you got problems.

Narrator: The only solution is
to use the tower itself

To shield the slosh-tank panels
from the wind.

You use whatever, you know,
building you have poured

As a protection from the wind.

The operator has got to sneak
them in behind the walls

And keep them down
below the windstream

So those panels do not
get jeopardized by the wind.

♪

Narrator: But the weather throws
them a curve ball -- dense fog.

The tower suddenly disappears
below mike,

And he's flying blind.

Femali:
This tower is full of ice.

It's foggy, maybe 20-foot
visibility,

And we can't see the ground.

We can't see what we're doing.

We can't see anything, so we
have to depend on their signals.

Narrator:
The work is dangerous,

And progress
is agonizingly slow.

Femali: There's no room
for error. There really isn't.

You have to trust the guys
that you're working with.

♪

Narrator: The team battles
through the worst

Of the weather,
and panel by panel...

Man:
Just tap it down.

...Cavernous slosh tank
begins to take shape.

Down, stop.

The crane lowers in
the giant steel paddles.

We're coming down!

And workers suspend them

Precisely 3 inches
above the tank's floor.

Coming down another
3 inches, mike.

Landed!

They pour the lid, and another
slosh tank is complete.

But there's no rest
for the weary.

The concrete crew pushes on
to build the three remaining

Giant tanks,
while 500 feet below,

The window crew faces a daunting
challenge of its own --

Clinging to the outside
of the tower.

I tell everybody, "it's the fear
that keeps you alive."

♪

Narrator: In chicago,
the vista tower is nearly

At full height,
but it's still missing

Half its signature feature --
its glass.

The vision had always been
to have this gradation

In the building
that reflected the colors

That are in lake michigan.

The water goes from green
to gray to blue to aqua.

It's really amazing
and beautiful.

Narrator: The designers are
blending six colors of glass

From dark to light
to accentuate the curved shape

Of the building.

♪

With these six colors of glass,
it's going to be just

An architectural icon.

You guys going to have
another record day today?

Narrator:
Shane jenkins heads up

The skyscraper's
window-installation crew

Tasked with placing
15,000 glass panels.

Jenkins: Typical unit is
installed from the inside.

The window is set on its sill,
and it's tipped up into place.

Narrator: The glass needs to
wrap around the entire building.

All good?

But at three places
along the perimeter,

The vista has solid walls
that block the crew's path.

Where you have a concrete wall,
you obviously can't set

The window from the inside
and tip it up.

Everything has got to be
set from the outside.

Narrator:
Shane and the window crew

Have come up with
an ingenious solution.

First, engineers attach
strong steel tracks

To the base of
the tower's outer wall.

Next, they attach a giant
four-story scaffold

To these tracks.

This allows workers to swing
the specially designed

Glass panes out of the building
and bolt them to the wall.

Once they finish a row,
hydraulics push the whole

Scaffold up the track, elevating
crews to the next floor.

When they run out of track
above, engineers bolt

The scaffold to the wall itself

And detach the track and slide
it further up the wall.

This extends the pathway
for the scaffold to climb

Until it reaches the top,
800 feet above the city below.

Galvan: All right, you got
a little tension on there now?

Narrator: The daredevil team
working on the scaffold

Is led by rolando galvan jr.

Galvan: First, I was wary about
it, like, "what am I doing

Standing on this thing?
How's it hold on?"

Kind of weird,
but we accepted it,

And we just kept
rolling with it.

You know, we got a job to do,
you know?

Coming up.

Narrator: 42 floors up,
the crew climbs outside

And begins swinging the panels
off the building's edge.

Galvan: Bring it out.

Narrator: Each half-ton panel
must spend as little time

As possible hanging from
the scaffold's narrow chains.

Man: Let me get
a temp on here.

Speed is essential.

All right. That's what
we want. That's cool.

All four crew members
on the scaffold work in sync

To set and seal the windows
as fast as possible.

We're good there,
james.

[ man shouting indistinctly ]

Yes, sir.

Galvan:
So it's like a train.

Like, everybody
is working in the flow,

So nobody's going to be
missing out on the action.

If you're not busy,
there's no reason to have you.

[ laughs ]

Narrator: Halfway along
the outside wall,

They hit a problem.

-Yep, he...
-A little high.

Yeah, sitting high over here,
that's the whole thing.

This window panel doesn't
line up with the others.

Crank it down.

Everything is designed
to fit perfectly,

But sometimes extra muscle
is needed, too.

We haven't
checked it yet.

Man #2: We're down!

There you go.

Okay, coming down.

The crew maneuvers
one panel after another...

Easy now.

...Until they cover
the concrete wall.

I'm right where
I need to be.

But the real test is when
they move inside

To squeeze in
the final few panels.

Keep an eye on it.

We put the last panels
on the floor

To close off the southeast
corner of the building.

Narrator: The window units
are millimeter-accurate.

Got it.

If this final panel doesn't fit,
they know they've messed up.

Galvan: That's what keeps
them together,

Is nice and tight-sealed
vessels, and, like I said,

No air or water
will get through.

If they're not,
something's wrong.

Narrator: It's a tight fit.

But eventually it's in.

That's all, folks.

So those windows
look good down there?

Yeah.
Everything is cool

Everything is good,
lining up.

All right.
Sounds good then.

We'll be jumping up
to the next floor.

Narrator:
This floor is finished,

But above, the penthouse levels
are still being designed.

There is no time to come
back and fix anything.

To make the changes.

and get it right the first time

Because there's an army
of workers in hot pursuit.

We have up to 50 to 60
framers on one floor.

Once it gets going,
it's eight hours of, you know,

Just go, go, go.

Narrator: Victor's team powers
through another penthouse

And moves on to the next one,

But they can only work
on watertight floors

With windows already in place.

This puts pressure on
window superintendent

Shane jenkins and his team.

They getting down

That's what we need
to start setting.

Every trade has got
their own schedule

That they have to stick to,

So we're the first, you know,
step in that process.

We have all the other trades
that are coming up right behind

That are waiting.

Narrator: The crew setting
the windows from the inside

Are up to the 84th floor.

To stay ahead of
the carpentry team,

Shane has no option but to
split this window team

Into separate units.

We have crews that set just
the sills,

Which is the bottom
framing of the windows,

And then we have separate crews
that come in

And install the heads.

Then the windows are set
and installed

In between the heads
and the sills.

Narrator: Each crew
sticks to one role

And becomes expert at it.

Jenkins: So if you were to
have one crew do it all,

It would take forever,
so it's got to be a fluid motion

Of everybody
moving up the building.

Narrator: The tower's windowsill
installation crews lead the way,

Battling their instincts
in order to lay track

For the windows
inches from a 1,000-foot drop.

Jenkins: The typical thought is
that guys up here working

This high, looking over the edge
are not afraid of heights.

But they are.
They're terrified of heights.

You're constantly making sure
you're tied off,

Constantly making sure
that whatever tools you have

Are also tied off.

It's the fear
that keeps you alive.

Man:
Just locking it in.

Narrator:
Once they lay down the sills,

Workers use a laser
to level them off.

It doesn't look bad
right now.

Millimeters count.

They need to leave a perfectly
sized gap for the windows.

So there's a tolerance built in
to where that window can move

Up and down inside
the head and the sill.

the window header above.

This team needs to work
in perfect tandem

To make sure the window frame
is spot on.

Narrator: Another floor of
window framing is complete.

Once the windows are in place,

Shane's next step
is to prove they're watertight.

Jenkins: We have to create
the facade that gets

Everybody watertight.

If we can't provide that,

Then the building is
at a screeching halt.

Vista tower are
on the final stretch.

The windows are rising quickly,

But it's all for nothing

is putting this tricky

Balcony section to the test.

They rig up high-pressure hoses
to pound the balcony windows

With a simulated rainstorm.

So obviously if no water
penetrates the panel,

It's a passed test.

Narrator: This super tall
skyscraper will need to pass

A tougher test
than most high-rises.

With the size of this project,

We're testing the wall
a little bit more.

Narrator: The inspectors enclose
the windows with

Airtight sheeting
and use an air pump

To try to suck water
in from the outside.

This technique mimics
the onslaught

Of a chicago storm.

Man: With the vacuum pressure,
we're basically simulating

77.5 miles per hour
for a sustained 15 minutes.

That's a pretty
significant storm.

Narrator: The inspection team
hunts for any signs of moisture

On the inside
of the balcony windows.

Man: We leave nothing to chance.

We build the building as if
we're building our own house.

My house,
I don't want it to leak.

I don't want the owners'
building to leak either.

And with no signs of moisture,

They switch off the pump.

No water observed
which is a pass, so great news.

at the top of the building.

This process is called
topping out.

♪

Head of concrete kevin morley
is under pressure.

He has just 10 days to top out
and finish the vista tower.

The summit is right there
on top of that rebar,

So the idea is to get to there,
top out, and be done.

That's the end of our job.

Narrator: Workers rapidly finish
the last levels.

Now they have to pour
one more slab

At the very top of the tower.

This will be the last time
I use this.

♪

Narrator: But on the morning
they're set to top out,

The wind returns.

Morley: Right now,
the winds are picking up,

So it's kind of dodgy
for the top.

We got about 45 mile an hour,

And they're supposed to increase
throughout the day.

Narrator: The wind could
prevent their crane

From being able to lift
the concrete bucket to the top

And even knock the elevators
out of action.

Morley: So you see
that power cable

Shifting into the building?

If it gets tangled up,
we lose power to the skip

And we get stranded up there,

So we got to keep a close eye
on that cable.

So I'm going to come over.
I'm going to call phil.

Rich is going
to watch the cable.

Narrator: The team anxiously
waits to hear from

The hoist operator
if they can proceed.

-So what's it clocking?
-All right. Get some out here.

Narrator: It's a go.

Yeah, let's go.
Fly it up.

Man: Okay.

Wait.

But as v.I.P.S gather
for a press call

To mark this milestone...

Hey, max!

...Kevin's team spots a gap
around a section of pipe.

[ indistinct chatter ]

A hole in the roof would send
wet concrete cascading

Into the slosh tank below.

Should've been done yesterday.

♪

Narrator: The crew quickly
patches up the hole...

Here you go.

...And tapes over the joints
as an extra precaution.

They can't take any risks today.

Man: The wind is going to take
the cable for sure.

Narrator:
With the wind speed rising,

The last bucket
can't wait any longer.

Get in there, kathy.

And with
one last team push...

One, two, three.

♪

...The vista tower
hits full height.

Congratulations.

It's a team effort.

-Thank you, guys.
-Congratulations.

Thank you.

Job done, on to the next one.

Narrator:
It's been a herculean effort

From the construction crew.

It's a tremendous effort
on everybody's part.

Narrator: Now the workers focus
on putting the final touches

To the tower.

Schaack: Everybody has to be
on their "a" game.

It's very much a team effort.

Narrator: The skyscraper's
stunning windows reach

The summit, and this
1,200-foot-high building

Becomes the most radical
and elegant skyscraper

On chicago's skyline.

The sense of accomplishment
is pretty deep.

This one is special.

A lot of us have smaller kids,

And when we're gone,
that's our legacy.

"our moms and our dads
worked on that building.

They helped build
that building."

You know, that's important
to a lot of us.
