Working with foundations Part 2

00:02

After completing this lesson,

00:03

you'll be able to place and set out piling create linear arrays

00:09

and work with model groups.

00:11

The objective domains covered are 1.1 a work with foundations and

00:22

A linear array can be used to set out piling with regular distances between pole

00:27

centers or used to distribute a required number of piles along an element's length.

00:33

When the linear Aral

00:34

is used, you have the option of grouping these elements together.

00:38

Therefore, if you make changes to the elements, setting out all the other groups,

00:41

objects would update

00:43

certain restrictions apply when grouping elements.

00:46

For example, if you have a pile that is located on a grid, by default,

00:51

the pile will move with grids.

00:53

If you then group the piles without the grid,

00:56

the relationship cannot be maintained.

00:60

Go ahead and open up the model 012,

01:03

work with structural foundations. Part two,

01:06

the model opens up in a 3d view.

01:10

Our first task is to place some piling along a ground beam

01:14

to do this. We're going to open up the top of foundation plan.

01:20

Let's zoom in to grid three.

01:22

And you'll notice on grid three,

01:23

we have this ground beam passing through this grid position.

01:28

Here,

01:29

we're going to place three piles into the ground beam and

01:32

then group those piles together and copy them to other locations.

01:36

So let's begin by clicking the structure ribbon

01:39

and then isolated

01:42

in the properties paddock

01:44

in the type selector,

01:45

ensure that you have round in situ concrete pile families selected.

01:49

And here we're going to use our 16 inch diameter, 16 ft long pile.

01:56

You'll notice in the properties pad that the level that this

01:59

is constrained to is negative 01 top of Found Ocean.

02:03

You'll also notice here that we have a height offset from level of minus 2 ft.

02:08

That's so our pile is set out on the soffit of our ground beam.

02:14

So now we can go ahead and place out our first pile.

02:18

I'll then place another one at an arbitrary position on this grid here

02:21

and another one to the left,

02:25

we can now use temporary dimensions to set out these piles.

02:29

So I'd like to try and maintain 2.5 times the piles diameter.

02:33

So in this case, that's going to equate to 40 inches.

02:37

I've selected this pile here.

02:39

You'll note that the temporary dimensions,

02:41

Witness line isn't attached to the correct element.

02:44

So I can simply drag this to the pile center.

02:47

And here

02:49

again, stipulate 40 inches.

02:53

So our piles are now set out the next step is to group these piles together.

02:59

Now,

02:59

one of the things we have to be mindful of is the first

03:01

pile that I placed down is positioned on this grid line here.

03:06

So consequently, when I group these together,

03:09

because the grid's not gonna be in the group rev, it will show a warning.

03:13

Let's go ahead and select our foundations. So I'm going to window select them

03:18

and then we'll use the filter

03:20

to remove the structural column.

03:22

So we've only got the three piles in the selection set.

03:27

Notice up on the context ribbon, I have the option of creating a group.

03:34

Now, as I've said here, you'll notice that these piles are currently set out on grid

03:39

here.

03:39

Rev It is informing us that a structured element will

03:41

be detached from the grid due to inconsistent group membership.

03:46

That's fine. We'll click OK here

03:48

and we can name the group. So I'm just going to call this 13 pile

03:53

setting out

03:58

and then click. OK.

04:01

Now you'll notice here that we can adjust the origin of our group.

04:05

I'm going to have this on the grid intersection.

04:11

OK.

04:12

So now that we have our group created,

04:14

we can then proceed to use the group to populate other grid intersections

04:19

to do this.

04:19

If we look in the project browser, we'll notice that we have a folder titled groups.

04:24

And here we have model groups.

04:27

Here's our group that we've just created.

04:29

I can simply drag and drop from the project browser

04:32

and then place the group down on another grid intersection.

04:38

If we now go into the 3D view and review our model in three dimensions,

04:43

we'll now see these piles in groups.

04:47

A nice property of a group is that if I want

04:50

to go ahead and perhaps change the length of these piles,

04:53

I can select the group

04:54

and on the context ribbon, I can edit the group.

04:58

Now,

04:59

it might be here that we have a requirement for the center pile to be slightly deeper.

05:03

So I've selected this pile here

05:06

in the properties padded in the type selector, I can use a 16 inch diameter pile.

05:10

But this time 24 ft long

05:14

note, when I click the finish tool over here,

05:18

all the groups update.

05:21

Now, if I didn't want them all to update, I could choose one of the groups

05:25

and I could perhaps

05:27

gro

05:27

this which will convert this back into three different elements.

05:34

Next, we're going to use an array to create a linear pattern of piles.

05:39

Let's open up the negative 02 lift pit plan

05:46

here, we're going to place some piling underneath this structural wall here.

05:51

Now, here we have a foundation slab which is 24 inches deep.

05:55

We need to make sure that the top of the pile is set down 24 inches.

05:59

So we're going to adjust the height offset from level of our pile.

06:04

So on the structure ribbon select isolated

06:10

notice here that we have our 16 inch diameter pile. Once again, it's 16 ft long

06:16

and we'll place our first pile on the intersection of these two walls.

06:22

But note here that we have a high offset from level of 2 ft.

06:28

OK. So I'm now going to array this pile so we can select the pile.

06:33

And on the context ribbon, we have the

06:36

areal.

06:37

Let's go ahead and select a ray

06:41

on the options bar. We have either a linear pattern or a radial pattern.

06:47

The default is a linear pattern

06:51

here, we can stipulate the number of items that we want in the array.

06:55

And here I'm going to move this to the second item

06:59

so I can snap to the original pile that I've placed down,

07:03

move my mouse to the right. And again, here I need to use 40 inches for our setting out.

07:11

So you can now see that we have our piling laid out. Currently, I only have two piles.

07:16

So here we can adjust this.

07:19

So perhaps we could set this to eight piles

07:22

and you can see that almost takes us to the edge of the wall.

07:25

Now, what I could do here is simply stretch out these piles.

07:28

So I have eight piles set out along the length of that wall.

07:31

If I wanted to do that, I could take the last pile here

07:35

and drag it. And you can see that it would snap to the center line of that wall,

07:40

our piling is now set out.

07:43

Now, once again, here, if we go into the 3d view,

07:46

we'll note that that piling now resides inside a group.

07:51

Of course, if I wanted to change the item inside the group there,

07:54

I could edit the group,

07:56

we could select the pile.

07:58

And as we saw previously, we could change the length perhaps to 24 ft

08:04

click finish.

08:06

And of course, all the piles update.
