RUSS NICLOY: Now, in Civil 3D, we're

00:15

going to come back in here to calculate the raw materials

00:19

and the grading quantities for the roadway

00:21

that is coming up to our Bridgeway here.

00:23

The first thing we need to do for that

00:25

is to create a surface on the corridor

00:30

for the subgrade information.

00:31

So I'll select on the corridor.

00:33

Go to Corridor Surfaces.

00:35

Under the Surfaces tab, I'll select and add a Surface.

00:39

This is the road subgrade.

00:44

I'm going to go to the Data type Links

00:46

and choose the code of Datum, and click the Plus sign,

00:49

and add that in.

00:51

I'm also going to go to the Boundaries tab, right-click,

00:54

and corridor extense is out of boundary.

00:57

This should create a boundary on the outside edge

00:59

and rebuild the corridor so that we

01:02

can get just the surface in that area there.

01:06

You can see it's done that.

01:09

I am going to hit Escape and let go of the corridor.

01:11

I'm going to hit Save, so we can save the file.

01:14

And then, I'm going to create the sample lines

01:17

along this roadway so that we can measure

01:19

the volumes for this side that's on the West side

01:22

of the project.

01:23

I'll go to the Home tab of the ribbon, Profile and Section

01:26

Views panel, Sample Lines.

01:28

I'm going to hit Enter, so I can select it from a list.

01:31

And if you remember, a 19 was the alignment

01:33

that we were dealing with there.

01:36

And in here, I don't want the existing transportation

01:39

or proposed ground.

01:40

Those are Infraworks ideas of what

01:42

was going on with the road.

01:43

I do want the existing ground 19,

01:46

which is the corridor and 19 road subgrade,

01:49

which is the surface we made from the corridor.

01:52

So I'll go with that.

01:53

I am going to change the subgrade surface

01:55

from Existing Ground to the Finished Ground style.

01:60

I'll click OK.

02:02

And now, I'm going to pick in the sample line tools,

02:08

this button here to create a bi-range of stations grouping.

02:12

I'm going to start from the very beginning,

02:14

but I'm going to end this batch, this volume calc batch,

02:21

to the end of the roadway there, at the end of the corridor,

02:24

before we get to the bridge.

02:27

I'm also going to widen the width of the left swath

02:31

and the right swath.

02:35

We will make these every 50 feet,

02:37

and I am going to start at the range start and the range end

02:42

because they're not at nice round numbers

02:44

or probably aren't at nice round numbers

02:46

and we want volume calcs right up to the edge.

02:49

So I'll click OK, and drops those in.

02:51

By back up, I still am in the sample line creation tools

02:57

until I right-click and let it know that I'm done.

02:59

At that point, it will add the labels

03:01

to all of the sample lines, so I know that that calculation

03:05

has been done.
