0:00:01.513,0:00:04.113
(Announcer) Civil engineering[br]is everywhere.

0:00:04.113,0:00:07.733
It's in every road you drive.[br]It's in the clean water you drink.

0:00:07.733,0:00:12.794
It's where you live, work, and play.[br]it really is all around you.

0:00:12.794,0:00:16.823
Civil engineers help improve the lives[br]of millions of people every day.

0:00:16.823,0:00:20.034
We're gonna meet three civil engineers[br]and look at some of the real ways

0:00:20.034,0:00:22.264
that they're helping [br]communities right now.

0:00:22.264,0:00:25.324
America's water waste system [br]is home to an entire ecosystem.

0:00:25.324,0:00:27.063
The animals that live in the water,

0:00:27.063,0:00:29.345
depend on us to keep their [br]communities clean.

0:00:29.345,0:00:30.815
This is James Wanaburg.

0:00:30.815,0:00:32.844
James is working to [br]create a healthy habitat

0:00:32.844,0:00:35.825
and ecosystem in Washington[br]D.C's Potomac River.

0:00:35.825,0:00:38.074
He's a resident engineer for The[br]Blue Plains Tunnel,

0:00:38.074,0:00:40.017
part of the DC's Clean Rivers Project.

0:00:40.017,0:00:42.384
This tunnel project is [br]using a massive drill

0:00:42.384,0:00:45.806
that's almost 30 feet high [br]and over 400 feet long.

0:00:45.806,0:00:47.246
(James) This is my office.

0:00:47.246,0:00:48.886
(upbeat music)

0:00:48.886,0:00:51.974
We're here for D.C Water working[br]on the Clean Rivers Project.

0:00:51.974,0:00:56.226
This project is intended to[br]eliminate sewer overflows.

0:00:56.226,0:00:57.812
into the D.C. waterways,

0:00:57.812,0:01:00.432
which ultimately go down [br]to the Chesapeake Bay.

0:01:00.463,0:01:05.023
So, we're cleaning up the rivers.[br]Right now, we're working on a deep tunnel.

0:01:05.023,0:01:06.181
It's called the Blue Plains Tunnel,

0:01:06.181,0:01:09.213
and this is going to capture[br]storm water underground,

0:01:09.213,0:01:12.612
and allow that to be treated [br]later after a big rain event.

0:01:12.612,0:01:15.314
The tunnel boring machine[br]we're using here is

0:01:15.314,0:01:17.612
an amazing piece of equipment.[br]It's fantastic.

0:01:17.612,0:01:22.294
It's 26 foot diameter,[br]and it bores horizontally underground,

0:01:22.294,0:01:26.464
like a drill, and it holds back[br]all the earth pressures

0:01:26.464,0:01:29.414
and the hydro static forces[br]that are below ground at that depth.

0:01:29.414,0:01:32.784
It also allows us to install the pre-cast rings,

0:01:32.784,0:01:35.265
they're made out of [br]concrete, pre-cast segments,

0:01:35.265,0:01:37.905
and that ring forms the [br]pipe that will be there

0:01:37.905,0:01:40.474
permanently after we're [br]finished digging the tunnel.

0:01:40.474,0:01:44.038
Civil engineering is a, [br]it's a fantastic profession.

0:01:44.038,0:01:47.485
it really deals with engineering [br]all of the world around us.

0:01:47.485,0:01:52.075
There's infrastructure on the surface,[br]things that people see and use every day,

0:01:52.075,0:01:54.865
like roadways, bridges, [br]things of that nature.

0:01:54.865,0:01:58.115
Then there's also a tremendous [br]amount of civil engineering

0:01:58.115,0:01:59.799
below the surface that no one ever sees.

0:01:59.799,0:02:01.636
That's what we're dealing with here.

0:02:01.636,0:02:06.986
In my view, that's one of the best parts[br]of civil engineering

0:02:06.986,0:02:09.607
is working on the underground side.[br]It's so much fun.

0:02:09.607,0:02:12.267
I never imagined I'd be able [br]to work on something this cool,

0:02:12.267,0:02:14.127
but I always had an [br]interest in big projects.

0:02:14.127,0:02:16.140
I love being part of it. [br]It's a great mission.

0:02:16.140,0:02:18.417
I come to work everyday excited to do this[br]

0:02:18.417,0:02:20.387
and we can't wait to see the end result[br]of all the hard work.

0:02:20.387,0:02:22.467
My name's James and I'm a civil engineer.

0:02:22.467,0:02:27.257
(Upbeat Music)

0:02:27.257,0:02:29.606
(Narrator:) Hurricanes can [br]destroy entire communities

0:02:29.606,0:02:31.478
that then take years to rebuild,

0:02:31.478,0:02:34.548
Maggie Jakes is a Civil Engineer[br]who went to Haiti to help

0:02:34.548,0:02:36.977
restore clean drinking water[br]after the hurricane.

0:02:36.977,0:02:39.498
Maggie was forever changed[br]through her experiences

0:02:39.498,0:02:43.030
in Haiti, helping a desperate[br]community and touching lives.

0:02:43.030,0:02:45.229
(Maggie:) So, my junior year in college,

0:02:45.229,0:02:48.349
my professor did a presentation[br]on his trip to Haiti

0:02:48.349,0:02:52.829
and what he found when he was there.[br]Their biggest problem was drinking water.

0:02:52.829,0:02:54.619
They didn't have clean water to drink

0:02:54.619,0:02:57.890
and thousands of people are[br]dying each year because of this.

0:02:57.890,0:03:01.967
So, he was trying to get[br]civil engineering students

0:03:01.967,0:03:05.290
from Merrimack to travel there.[br]2011 we traveled to Haiti.

0:03:05.290,0:03:09.220
For the first time, we went[br]to a town called Manoir.

0:03:09.220,0:03:12.280
This is where severe cholera[br]outbreaks hit every year.

0:03:12.280,0:03:14.480
There's a big clinic there

0:03:14.480,0:03:17.661
and we saw all the[br]cholera tents still set up

0:03:17.661,0:03:18.990
from their recent outbreak.

0:03:18.990,0:03:22.380
The system was damaged[br]by the 2010 earthquake,

0:03:22.380,0:03:27.181
and it was broken in a few places,[br]but the water was relatively clean.

0:03:27.181,0:03:29.584
So, we made a few repairs to that.

0:03:29.584,0:03:31.662
They were just so grateful[br]that we were there.

0:03:31.662,0:03:33.392
Because we were there, we gave them hope.

0:03:33.392,0:03:36.601
In the United States, we're really lucky[br]to have access to clean water

0:03:36.601,0:03:40.332
and that's thanks to years[br]of hard working engineers.

0:03:40.332,0:03:44.650
My experiences in Haiti, and[br]my later years at college,

0:03:44.650,0:03:46.688
really opened my eyes to[br]how many possibilities

0:03:46.688,0:03:50.212
there really are for[br]civil engineers to help.

0:03:50.212,0:03:52.702
My name is Maggie Jakes[br]and I'm a civil engineer.

0:03:52.702,0:03:57.824
(wind blowing)

0:03:57.824,0:04:00.281
(crowd cheering)

0:04:00.281,0:04:03.795
(Narrator:) Ah, baseball,[br]the crack of the bat,

0:04:03.795,0:04:06.185
the roar of the crowd,[br]the amazing ball parks

0:04:06.185,0:04:08.212
that are home to our national pastime.

0:04:08.212,0:04:10.894
Meet Aaron White, the civil engineer

0:04:10.894,0:04:13.466
in charge of designing the[br]hurricane-proof retractable roof

0:04:13.466,0:04:15.074
at the Marlins Park in Florida.

0:04:15.074,0:04:16.864
(Aaron:) This is the first roof in the [br]world

0:04:16.864,0:04:18.694
that was designed for a[br]category five hurricane.

0:04:18.694,0:04:24.834
It weighs roughly 7,800 tons of steel[br]and it was actually designed to be[br]

0:04:24.834,0:04:28.435
positioned in a slightly open position[br]for the hurricanes to let wind

0:04:28.435,0:04:32.305
into the space and then back out[br]to decrease the wind pressure on the roof.

0:04:32.305,0:04:35.024
Obviously, anytime there's the threat[br]of a rain storm during a game,

0:04:35.024,0:04:37.395
you have the problem of a rain delay.

0:04:37.395,0:04:38.275
If you know Miami,

0:04:38.275,0:04:40.325
it rains here pretty much[br]every day during the summer.

0:04:40.325,0:04:42.695
So, they have the ability to[br]close the roof very quickly

0:04:42.695,0:04:44.869
if there's an impending[br]thunder storm or rain storm.

0:04:44.869,0:04:47.316
So, there's a guarantee[br]that the game's gonna happen every night

0:04:47.316,0:04:50.565
and that's extremely important.[br]The mechanization is very efficient.

0:04:50.565,0:04:53.085
It's designed so it only[br]costs about 10 dollars

0:04:53.085,0:04:55.206
in electricity to move[br]the roof open and closed.

0:04:55.206,0:04:57.875
So, early on in the design,[br]we tried to establish what

0:04:57.875,0:05:00.916
the minimum height of the roof[br]over the playing field actually is.

0:05:00.916,0:05:03.037
So, we scoured the internet

0:05:03.037,0:05:05.685
and found some equations[br]that were put out by NASA,

0:05:05.685,0:05:08.077
I believe, for the[br]flight of a batted ball.

0:05:08.077,0:05:11.257
Through those equations, you can actually[br]calculate the flight of the batted ball

0:05:11.257,0:05:14.292
at all different angles of[br]the ball leaving the bat.

0:05:14.292,0:05:18.037
So, if it goes straight up in the air,[br]it goes straight horizontally, or a nice

0:05:18.037,0:05:19.218
trajectory of a line drive.

0:05:19.218,0:05:22.047
So, we actually crated[br]those shapes early on

0:05:22.047,0:05:26.248
and put them over the playing field[br]to make sure that the shape of the roof[br]

0:05:26.248,0:05:28.717
that was above the playing field[br]would never come in contact

0:05:28.717,0:05:30.148
with a batted ball.

0:05:30.148,0:05:32.058
We really interact with a lot of people.

0:05:32.058,0:05:35.717
So, there's a common conception[br]that engineers just kind

0:05:35.717,0:05:39.086
of go in their office[br]and work by themselves doing calculations,

0:05:39.086,0:05:41.557
but that couldn't be[br]further from the truth.

0:05:41.557,0:05:43.800
I'm Aaron White and I'm a civil engineer.

0:05:43.800,0:05:50.760
(upbeat music)

0:05:50.760,0:05:52.938
(Narrator) Civil[br]engineers have cool jobs.

0:05:52.938,0:05:55.040
They're creative and innovative people.

0:05:55.040,0:05:59.540
They make an impact and change lives,[br]making our world a better place.

0:05:59.540,0:06:02.779
The bottom line, if you[br]want an amazing career

0:06:02.779,0:06:05.381
that makes a difference,[br]then do something real.

0:06:05.381,0:06:07.480
Be a civil engineer.

0:06:07.480,0:06:21.682
(upbeat music)
