All language subtitles for Impossible Engineering s10e04 Abandoned Resurrection.eng

In today's impossible engineering.

This is one of the largest regeneration
projects in Europe.

Engineers take on one of London's most
iconic landmarks. No one has ever tried

to put any kind of lift like this within
a chimney.

Attempting an epic transformation.

It is a seemingly impossible task.

Using groundbreaking innovations from
the past.

It's 900.

40 degrees in here. The Rockefeller
Center, the Chrysler Building, Madison

Square Garden, even the Empire State
Building all included beams made here.

That made the impossible possible.

London, England.

At the heart of this. sprawling
metropolis, lies one of its most

buildings,

Battersea Power Station.

Nearly 100 years old, in its prime, it
supplied electricity to a fifth of homes

and businesses in the capital.

But for more than three decades, this
once great cathedral of power had stood

derelict.

Battersea Power Station is a really
important, iconic building, partly

of the scale and size of it, but also
its location right in the centre of

and on the bank of the River Thames.

But now this legendary building is about
to be reinvented, and Sarah Banham is

part of the team facing the daunting
task.

I think Battersea Power Station is quite
unique.

It's in a lot of films, music. It's
instantly recognizable.

But it has been called the Everest of
real estate.

It wouldn't have stayed empty for over
30 years if it had been a simple

solution.

The plan is to radically transform this
immense 260 ,000 square foot building on

the banks of the River Thames.

On the inside, the old boiler house.

which is large enough to hold four jumbo
jets, will become six floors of office

space, plus apartments and an event
menu.

On either side of it, the two mammoth
turbine halls will be transformed into

retail space.

Next, the two former switch houses are
to be converted into over 200

apartments.

Finally, the building's four iconic
chimneys will be rebuilt.

and inside one, a cutting -edge glass
elevator will be installed, allowing

visitors to enjoy breathtaking views
across the capital.

Today, work is nearing completion on the
ambitious billion -dollar project

to turn this powerhouse of the past

into a cutting -edge centerpiece of the
city.

I think it's the biggest project that I
have worked on and certainly one of the

most challenging for me.

There isn't just one building that's
being built here. There are effectively

eight all rolled up into one massive
project.

On -site project manager Nacho O 'Leary
has his hands full.

So we're now approaching the east
elevation of the power station. This is

East Annex Wall.

What you can see above us is all the new
resident departments.

And this is the new glazing that we're
putting in for the shop front that will

be facing the phase one.

The size of the project is astronomical.

This is where the residents will be
entering into, coming in through the

landscaping from the side, using the
lift, and then going up to their

above.

More than 2 ,500 workers must excavate
the equivalent of 60 Olympic swimming

pools worth of earth.

install over 25 ,000 tons of steel
structure, and replace 1 .75

million bricks.

The redevelopment of Battersea Power
Station is one of the largest projects

going on in Europe.

It's significantly complex in terms of
the volume of work that we're

and the number of man hours that we're
working to, but also retaining the

existing building and respecting that is
a very challenging piece of work.

Many people have tried and failed to
redevelop the battery power station.

I've been on here since 2013, right at
the very beginning, so I know how

it is. It is seen as a very impossible
project for the undertaking, especially

for those that aren't involved.

To repurpose this 20th century icon, the
team is facing many extreme engineering

challenges.

How do you keep one of the world's
largest brick buildings standing when

slowly turning to dust?

The replacement of the 1 .75 million
brick is quite daunting.

And ensure that it doesn't simply
collapse when you start repairs.

This isn't just the biggest project that
I've ever had to deal with. It's the

most complicated.

How do you thread a new underground
railway through one of the world's

subterranean environments?

This is one of the biggest challenges
that London Underground has had for 30

years.

Finally, how do you transform a chimney
into a world -class tourist attraction?

It has never been done anywhere before,
certainly not at this scale, or even

attempted within a chimney like this.

The power station's four distinctive
chimneys are an iconic part of the

skyline, but they're in a precarious
state.

Nacho O 'Leary is responsible for
finding a solution.

The chimneys at Batsi Power Station are
the iconic part of the building that

people remember the most.

When I first arrived, we had large lumps
of the chimneys falling down from

height at 107 meters high all the way
down to ground level of where we are

So because the chimneys were in such a
bad condition, there was nothing further

we could do than to take them down.

Piece by piece, the historic structures
were carefully removed.

We employed a specialist steeplejack to
undertake the work because the works are

happening at such height.

In their place, four identical chimneys,
built from steel and reinforced

concrete, start to take shape.

And to ensure they're indistinguishable
from the originals, engineers have

replicated the construction method used
in the 1930s.

Instead of using a pump, 25 ,000
wheelbarrows full of concrete are taken

160 feet in an elevator and poured into
circular mold.

So once the concrete's set, we jump the
shuttering.

And where that jump occurs, you can see
where the horizontal lines are every

four foot.

Then nearly 400 gallons of protective
paint ensures they'll last the next 100

years.

A friend of mine asked why we hadn't
replaced the chimneys. He hadn't

that all four of them had been taken
down and had gone back up and were

effectively the same as they were
originally.

With the chimneys complete, engineers
can now attempt the most ambitious part

the project.

The chimney lift is a really large
passenger lift with an entirely glazed

The public will be able to come in and
get an incredible view across London

the top of the most iconic chimneys in
the world.

For engineer Adrian Forge, it's unknown
territory.

As far as we know, no one has ever tried
to put any kind of lift like this

within a chimney.

It's the chimney's unusual cylindrical
shape that makes building an elevator

inside the shaft especially difficult.

So normally a lift shaft is completely
straight, but you'll see the chimney

tapers. It's wider at the bottom than it
is up at the top, and that's not normal

for a lift shaft. You don't want your
lift rails being anything other than

completely plumb and straight, because
otherwise you have problems with ride

quality.

But the biggest challenge for engineers
is how to pull the elevator to the top.

Because we're trying to give people a
view from the top of the chimney, we

have any of our equipment at the top
getting in the way of the view.

A large motor at the top could also
damage the chimney structure.

The chimneys are designed to be
chimneys.

We are putting a lift inside it which is
heavy.

The machines that operate it are heavy.

And what we can't do in this lift shaft
is put all the weight, all the machinery

at the top.

because we know that the chimneys won't
be able to cope with that.

It's a formidable problem to solve.

It has engineering challenges about
every aspect of it, so it has certainly

given me sleepless nights.

To find another way of pulling this
elevator to the top, engineers need to

to history's great pioneers.

To convert Battersea Power Station's
iconic chimneys into one of the best

in London, engineers are turning to
their predecessors.

Could the structural difficulties of
adding an elevator to a restored chimney

overcome with guidance from the past?

Elevator manufacturer executive Patrick
Hess is discovering the secrets behind

an engineering masterpiece located high
in the Swiss mountains.

The Bürgenstock Mountain is famous for
its unparalleled views and it's been

popular holiday location since 1872.

So one hotel, the Bürgenstock Hotel,
wanted to provide something unique to

guests. They wanted to provide a few
from the summit.

And this was the result.

This is the Hometschwand lift.

The top is 3 ,700 feet above sea level,
making it the tallest

outdoor elevator in Europe.

But building an elevator on the side of
a mountain presents a monumental

challenge.

At the time, all elevators have the
machinery at the top.

But putting a heavy machine on top of a
tall elevator shaft would make the

structure too unstable.

Who would be the engineer brave enough
to tackle such a challenge?

Carl Lolle was a German bridge engineer.

But in 1905, he built one of the most
astonishing elevators in the world.

What a structure.

In the 1900s, a truly remarkable
undertaking and a huge engineering

The elevator shaft is a truss design.

influenced by Lole's railroad bridge
background.

To attach the shaft to the mountain, no
scaffolding could be brought here. So

builders had to uptail like acrobats on
rope in order to drill holes to make

anchor points for the steel structure.

Miners from Italy and Austria were
brought in with additional expertise

the rock needed blasting with dynamite.

The shaft needs to be straight to ensure
a smooth ride.

We think Lole must have used a plumb
line like this. It's a string with a

on the bottom to make the shaft
perfectly straight.

Lole's outdoor elevator was a game
-changing piece of engineering.

But the real brilliance of the system is
in the design of the mechanism.

This is the heavy machine which pulls
the car up and down.

After more than 100 years, it's now a
new machine, but it's in the same place

Carlole put the machine.

It's on the bottom of the lift and not
on the top.

At ground level, a large motor winds
steel cables connected to a drum at the

of the shaft.

As the system turns, the car is raised
and lowered as required.

This brilliant idea made the shaft more
stable and is protecting the machinery

from the difficult weather conditions.

is what it was all for.

Look at this outstanding view.

For the past 120 years, the Hamachfond
elevator has provided one of the most

scenic views of the Alps.

Karl Löhle, he was an engineering
pioneer.

He has made the impossible possible.

And he has inspired elevator engineers
around the world.

At the Battersea Power Station in
London, engineer Adrian Forge and the

have taken Lole's strategy to jaw
-dropping new heights.

So we can just get ourselves into the
lift shaft now.

Lift shafts are normally very protected
spaces. Not many people get to go

inside.

So we're right at the bottom of the
chimney now.

So the machine is...

I would say the biggest lift motor you
can buy. It weighs just over seven tons.

It produces 23 ,000 newton meters of
torque.

This chimney lift is absolutely
enormous, and that's why we need some

equipment to get it moving.

Just like at the Hummich Fund lift, this
monster machine is at the base of the

elevator shaft instead of the top.

By keeping all the equipment at the
bottom of the chimney, it means there's

nothing up the top that allows us to
bring the lift right out of the top of

chimney. It gives people an amazing view
across London from the top of the

chimney itself.

The elevator is pulled up by cables
attached to a massive steel ring at the

of the chimney.

Cables run down to the motor at the
bottom, back up to the top, and down to

counterweight. It's known as an
underslung elevator.

But as the chimney gets narrower towards
the top, engineers have also had to

devise an innovative way to ensure the
rails inside stay straight.

So these are the rails that the lift car
is going to run onto.

We know that this chimney isn't
completely straight all the way up, so

going to use these brackets, which are
adjustable, to make sure that we can

this rail really straight so that we can
give a really good ride quality as

people move up to the top of the
chimney.

To get people from the ground to the top
of the chimney, engineers have designed

a unique glass car with capacity for 30
people.

A ride to the top of the 350 -foot
chimney will take just 26 seconds.

The chimneys are iconic, and what we are
trying to create here is a truly unique

experience.

I know that I am going to have been part
of something incredibly special.

I think we are going to, at the end of
this, be looking on this as an

wonderful feat of engineering.

Engineers may have found a way to retain
the power station's iconic chimneys,

but now they face a more fundamental
problem.

The power station when we arrived on
site was sterile.

The largest space between the four
chimneys was entirely empty.

We needed to start putting in floors.

To solve it, the team will have to turn
to the great innovators of the past.

To construct a super tall tower,
engineers would need super strong steel

In London, the Battersea Power Station
redevelopment is one of the most

astonishing construction projects on the
planet.

This enormous industrial icon covers an
area over 260 ,000 square feet,

equivalent to 96 tennis courts.

Its steel frame consists of 8 ,000
individual sections.

Around that, six million bricks formed
the walls of the structure, making it

of the largest brick buildings in the
world.

But having had its roof and floors
removed over 30 years ago,

engineers now face the task of finding a
way to divide this empty shell of a

building into homes, offices, retail,
and event space.

It's the biggest engineering challenge
Michael Brooks has ever faced.

So, the power station when we arrived on
site was derelict.

Lots of the floors were missing.

The largest space between the four
chimneys was entirely emptied.

150 meters by 150 meters by 60 meters
tall.

The volume of space that needed filling.
We needed to start putting in floors.

The team plans to install 14 new floors.

The problem they face is that, unlike
the office and residential spaces at the

top of the building, which can be
supported with columns, the retail and

space below must remain open, forcing
engineers to find another solution.

We've got a retail mall, we've got
office space, we've got an event space,

all of these different uses have
different structural needs.

We can have columns within an office
space, but we don't want to have columns

an event space.

How do we overcome that challenge?

It is a seemingly impossible task.

To achieve strength on such an enormous
scale, engineers will need inspiration

from history's great pioneers.

Urban planner Cara Michelle is in
Bethlehem, Pennsylvania, uncovering a

revelation that is behind New York's
biggest skyscrapers.

In the 19th century, Manhattan's
population was booming.

And the only way to accommodate everyone
was to build higher.

By that time, buildings were already
starting to get taller, but they were

typically limited to about 20 stories.

To construct a super tall tower,
engineers would need super strong steel

Luckily, one man was working on a
solution.

In the late 1890s, English engineer
Henry Gray patented a new method for

creating steel beams that were much
stronger than those that currently

It was an innovation that would change
skylines around the world.

And it all started here.

This is the former Bethlehem Steelworks,
known as the place that built America.

The Rockefeller Center, the Chrysler
Building, Madison Square Garden, even

Empire State Building all included beams
made here.

Bethlehem Steel owners took a risk.

Henry Gray steel mills were new and
different, and almost no one else was

them. But they bought the patent anyway,
and they began manufacturing.

Gray steel rolling mill could make beams
stronger than had ever been achieved

before.

So what made these beams so resistant to
bending?

When a beam has weight on it, The top is
in compression, pushing the steel, and

the bottom is in tension, pulling the
steel.

By changing the shape of the beam, more
steel is at the top and the bottom where

it's needed most.

I've got two beams here.

They're both the same weight.

The only difference between the two of
them is their shape.

This one is a straight beam, while this
one is a wide -flanged beam.

So we're going to put these two beams to
the test to see which one is more

resistant to bending.

First, the straight beam.

Already, I'm hardly putting any weight
on it, and I can feel it bending

underneath me. It is so flexible.

I don't necessarily know if this is what
I would want to have holding up my

floor.

Now, the wide -flanged beam.

Already I can really feel the
difference.

And I don't feel that same amount of
give underneath me.

Actually, this is pretty impressive.

Bethlehem Steel's gamble had paid off.

By the 1920s, its beams were part of 80
% of New York's iconic skyscrapers.

Henry Gray was able to produce the wide
flange beam better than anyone else had

achieved.

His bend -resistant beams made it
possible to build tall, multi -story

buildings, changing skylines all across
America.

Back at Battersea Power Station.

Engineers are using bend -resistant
steel beams to make 14 new floors.

And one in particular needs to be able
to take the weight of eight new stories

by itself.

This gigantic beam is almost 90 feet
long and weighs a whopping 68 ton.

It's one of the largest pieces of steel
ever made in the UK.

Gray's historic wide -flanged beam made
this remarkable piece of engineering a

key component in Battersea Power
Station's redesign.

But now the team is faced with another
massive challenge, installation.

We had to run tests with lorries with
brooms and ladders out the back just to

make sure that we could actually
navigate the length of the beam through

site.

In the restoration and renovation of
London's historic Battersea Power

engineer Michael Brooks was charged with
one of the most difficult parts of the

entire process, delivering and
installing a record -breaking wide

that will support 14 new floors.

It was picked up by the second -largest
crane in Europe with a capacity just

enough to pick up this beam and install
it in place.

It was a very significant and obvious
milestone for us.

So here is the 62 -ton beam.

It is a supersized I -beam.

We have huge amounts of area of steel at
the top and at the bottom, and not so

much in the middle, and that gives us a
high bending resistance.

Located on the building's fifth floor,
the gigantic beam supports the weight of

the eight stories above.

leaving the event space below column
free.

Then, by adding two vast steel trees,
engineers are able to create floors for

offices above, maximizing the space.

These are the structural transfer trees.

We have one column underneath, what we
call the trunk, and sprouting out of it

are four branches that then divide again
further up into eight branches, and it

travels all the way up to the underside
of the level five, which is where we

have the office space above.

Each of these trees...

supports six office columns.

And by taking six columns above and
pulling all of the load down into one

central megacolumn below, what we've
been able to do is create this grand

as people walk into the retail mall and
yet allow us to maximize the space for

the office above.

The power station redevelopment is well
underway.

But with no direct underground rail link
to the site, the team still needs to

find a way for people to get here.

So with the regeneration of the area,
there's going to be around 20 ,000 new

jobs created, which will mean that we
need a transport hub to bring people in

and out.

For Jonathan Cooper, it will require
some of the most complex engineering on

project. We are going to build a new
underground tube station at Battersea

Station. This is one of the biggest
challenges that London Underground has

for 30 years.

Engineers have formed an ambitious plan
to dig a pair of tunnels almost two

miles long, connecting the site with the
existing northern line.

And where the old and new sections of
tunnel meet, junctions will need to be

created to accommodate the additional
section of track.

We've got to connect the existing
northern line, which is around 100 years

into the new tunnel. This is really
difficult because... The tunnel that

connecting into has to remain
operational at all times.

The process starts with two 700 -ton
tunnel boring machines being lowered 85

feet underground.

Watch the step here.

So this is where the tunnel boring
machines were brought down in 20 -metre

sections. They were put together and
pushed into the launch tunnels.

Moving at two inches a minute, they
grind through the London clay.

Behind the boring machine, the freshly
excavated tunnel is sprayed with

to create a reinforced lining.

It is very dark down here.

Roughly halfway along the route,
engineers face the most precarious part

process,

tunneling just six feet below the
existing Victoria Line.

While we were tunneling through this
area, the operational service continued

whole time, and no one even knew that we
were tunneling under here.

We're so close to the Victoria Line
train here that you can actually hear

trains going above us when they pass.

Right there.

After tunneling for nine months, the
team eventually reaches the site of the

existing Northern Line.

But there's one final problem to
overcome.

In order to tie the old line to the new
one, engineers must connect the two with

a junction.

To do this, they dig a larger tunnel
around the old one, revealing the

cast iron tube that dates back over 100
years.

Next, a prototype machine lines the new
larger tunnel.

Meanwhile, inside the existing tube,
trains continue to run.

Then, with the services halted for the
weekend, the old section of cast -iron

tunnel is removed and the two
underground lines are connected.

This is where the new tunnel joins with
the old tunnel.

It's really awesome to see a train
running in the underground because it's

restricted area, and normally you can't
see this.

This has been the biggest project I've
ever been involved in.

I'm really excited about seeing it
complete.

Back on site, the team still faces one
of the biggest challenges of the

Battersea Power Station project.

We think we need an order of 1 .75
million for it.

To tackle this 21st century problem,
engineers will need to look to the past.

You can totally see it's glowing almost
bright white.

In the heart of London,

Battersea Power Station, once an
essential piece of infrastructure that

electricity to the capital, is being
reborn.

After laying derelict for more than 30
years, today engineers are converting

this iconic structure into a brand new
neighborhood.

where future generations will live,
work, and play.

So far, the structure's four famous
chimneys have been rebuilt, with one of

transformed into a unique glass elevator
that will offer visitors stunning views

across the city.

27 ,000 tons of steel has helped to
construct 14 new floors.

And the London Underground has been
extended by nearly two miles, giving

Battersea its own station.

But on site... We've just got a ramp
here.

Be careful here.

Project manager Nacho O 'Leary still has
one final, crucial problem to crack.

Battersea Power Station is one of the
biggest brick buildings in Europe.

Over a number of years, the bricks have
been exposed to the elements of water

and also to wind.

A number of the bricks that you can see
have already defaced, just purely down

to the lack of maintenance that happened
for about 30 years whilst the building

laid open.

In total, over 6 million bricks were
laid by hand when the structure was

originally constructed back in 1929.

But more than nine decades later, this
aging brickwork is presenting a problem

for Nacho and the team.

Where we've had the water ingress come
through, some of the damage has meant

that a lot of the bricks are actually
unstable.

This is a prime example.

It's got a lot of mortar around it, and
this crumbles away quite easily.

The mortar is actually not holding the
bricks in at heights of 56, 58 meters

high. We're having to take out the
unsafe structure to make sure that

damage to the builders below.

With the crumbling, weathered bricks and
mortar in the process of being removed,

Engineers will need to replace them with
new materials. But this presents a huge

problem. We think we need in the order
of 1 .75 million bricks just for

replacement. So that's not including the
new walls that have gone up. That's

just replacing bricks that have been
exposed over time to the elements.

But making 1 .75 million new bricks that
match the original is a huge challenge.

Engineers will need to look back to the
19th century for the solution.

Archaeologist Kathy Newland is in
Gloucester, England, exploring how an

brick production technique could help
make millions of bricks for Battersea.

Bricks are absolutely essential in the
Industrial Revolution.

You've got all these infrastructure
projects. You've got canals, you've got

bridges, you've got housing, you've got
factories.

All those things absolutely depend on
bricks.

The problem was that brickwork simply
couldn't keep up with the enormous

Making bricks is actually quite a fine
art.

You've got to heat it up really slowly,
really gently, hold it at firing

temperature for a perfect amount of
time, and then cool it just as gently.

If you do it right, you get something
like this.

If you do it wrong...

You're going to get this.

Boldy, cracky, not fired properly, not
structurally sound, absolutely no good

for engineering.

And it's a process you just can't rush.

Fortunately, in 1858, German engineer
Friedrich Hoffmann invented a system

would revolutionize production.

Rather than using separate ovens to fire
bricks, Hoffman's innovation used

multiple interconnected chambers that
allowed heat to pass between them,

a vast number of bricks at the same
time.

At the Northcott Brickworks, their
gigantic Hoffman kiln measures 130 feet

64 feet long, and is capable of holding
up to 264 ,000 bricks.

If we look in the ceiling, we can see
feed holes. This is where the fuel comes

in. Right at the beginning, in the
1850s, this would all have been coal

down around the bricks.

And if we look down in the corner, down
here, there's a second set of holes

really low down. These are called the
trace holes. And they are kind of the

genius bit of Hoffman's invention.

They allow you to use the hot gases from
the combustion chambers, draw it

through all of your other chambers to
preheat those bricks.

And that's why Hoffman design is so
cutting edge. It saves you time, because

they're already preheated, and it saves
you money that you're not spending on

coal.

When one set of bricks is being fired,
the chambers near it warm up too.

So when the next chamber is fired, the
bricks are already preheated.

And when bricks are finished, they're
kept warm, allowing them to cool slowly.

That's the first chamber, and that's
being set.

The second chamber here, bricks are all
in there. There's something like 16 ,000

bricks packed into that little space.

And then you brick it off with these
bricks, which is what you call the door.

And then we go down to the third chamber
where the bricks have been sealed.

You've had this sort of clay mixture put
on it to keep all the air out to make a

decent seal.

And then round here is where it gets
really hot.

Now this is all ready to go and it is
being fired.

It's 940 degrees in here and it will be
kept to that temperature for another six

hours.

And it's really throwing out some heat.

Now coming round this corner, this one's
cooling down, making sure those bricks

come out perfectly.

It takes about three days to get from a
freshly fired chamber to cool enough to

deal with.

Having a Hoffman kiln could increase a
factory's production from 2 million

bricks a year to 20 million.

Thanks to Hoffman and his innovative
kiln, enough bricks could finally be

produced to meet the demands of the
Industrial Revolution.

And because of the savings in time and
in fuel, two Hoffman kilns were being

built all over the world.

Hoffman's pioneering kiln proved so
effective and durable, some are still in

today. And Battersea Power Station's
engineers... This kiln is so good that

is as efficient as a modern -day kiln.

...will put one in particular to good
use.

To meet their need for over a million
new bricks, the engineers at Battersea

Power Station... have turned to this
historic Hoffman Kiln at Northcott

Brickworks.

The very same one that the original
bricks for the building were fired in

in 1929.

Overseeing the massive undertaking, Dale
Moss is confident that Friedrich

Hoffman's innovation will deliver.

The Hoffman Kiln is vital.

It gives you variation.

It enables the beauty of the brick to be
achieved.

Unbelievably, most of the 1 .3 million
bricks are being made by hand.

And Dale has an innovative technique to
ensure the new bricks precisely match

their 95 -year -old counterparts.

We've developed our own weathering
antiquing process where... We can age

bricks to match old buildings.

So we weather them by putting them into
water, into weathering fluids for

various times.

The new bricks blend seamlessly with the
originals.

Personally, making the bricks the
Battersea Power Station is my biggest

achievement.

Back on site.

Bricklayers are painstakingly laying new
bricks to carefully match the original

pattern.

There are over seven different types of
brick and 20 different types of mortar.

This mammoth task will take around five
years to complete.

But at the top of the building, project
manager Nacho O 'Leary faces another

problem.

Over 160 feet in the air, here it's too
difficult, dangerous, and time

-consuming for workers to lay individual
bricks by hand.

This is the east wall of the boiler
house.

We've had to replace the bricks that
were originally here.

There's about 750 ,000 bricks in this
facade alone.

So, to speed things up, the team created
giant 13 -foot square brick panels.

that can be lifted into place quickly
and safely by a crane.

By using panels, not only was it easier
for us to install and had less impact on

other works going on, but it was a lot
quicker way for us to actually mount the

volume of bricks we had to the wall to
form the wall itself.

That reduces risk on site, and that's a
massively significant point to flag when

using panels.

This historic power station that stood
derelict for decades

has been transformed.

I'm very proud to save this wonderful
historic building.

Battersea Power Station is without doubt
the most exciting engineering project I

have ever.

been involved in.

It's been a privilege to work on one of
the largest brick buildings in the

world.

And it's a very proud project for me to
be involved with.

The thing that I think we like most
about it is the challenge.

The engineering skill behind it has been
tremendous.

Inspired by the innovators of the past.

By adapting their ideas.

and refining their design.

I'm really excited about the opportunity
to be a part of this project that will

push the boundaries of structural
engineering.

Engineers have breathed new life into
this iconic structure.
