Manage Clashes and Create Issues

00:01

DEEPAK MAINI: Welcome to the first objective of this course.

00:04

In this objective, we are going to manage clashes and create

00:07

issues.

00:10

One of the most important rule of thumb in managing clashes

00:13

is that not every clash that we see is a problem.

00:17

So for example, in our case, we have not

00:19

modeled the penetrations yet, but we

00:22

can see those penetrations as clashes in the model.

00:25

In this case, we can select these clashes

00:27

that are valid penetrations and we can mark them as non-issues.

00:32

However, the clashes that are problematic we

00:36

need to address them.

00:38

And the way we address them using the Model Coordination

00:41

module is by creating issues on those clashes

00:44

and then assigning those issues to the individuals who

00:48

could then go into the authoring tool like Revit

00:51

and fix those clashes.

00:53

So let's jump straight into the Model Coordination module

00:56

and look at this workflow.

00:59

As you can see, I'm in the Model Coordination module

01:02

and currently I'm on the Views tab.

01:05

In the last course, we created these two views.

01:09

These two views were created using

01:11

the models that are available in the shared file coordination

01:14

space.

01:15

In this case, I'm going to click on Plumbing vs Structure view.

01:21

It now opens the view with these two models federated.

01:24

I'm going to click on the Clashes panel,

01:29

and now I can see where there's clashes.

01:31

But at this stage, these clashes are grouped by the structure

01:33

elements, so I'm going to click on the model dropdown list

01:37

and pick the plumbing view from here.

01:41

Now these clashes are grouped by the plumbing elements,

01:44

because these are the elements that we have to modify.

01:47

Now this is where we can start interrogating these clashes.

01:50

So we can start looking at all these different clashes

01:53

one by one.

01:54

We can also click on these clashes in the Clashes panel

01:57

on the left.

01:58

So for example, if I click on this particular clash here,

02:03

we can now see that that's the problem right there.

02:06

Similarly, if I go to another clash,

02:12

we can see that that's the problem right there.

02:15

Now as I mentioned earlier, some of these clashes

02:17

could be non-issues.

02:19

In my case, I know that I have not modelled penetrations

02:23

on the slab.

02:24

So I can click on this slab here.

02:26

As soon as I do that, it now selects 17 clashes.

02:30

These 17 clashes are with this particular slab.

02:33

If I want, I can review these clashes one by one

02:36

to make sure that I've picked all the right clashes, which

02:40

in this case, I know I have.

02:43

So I can now change all these clashes into non-issues.

02:47

So let's click on this Not an Issue button.

02:52

Now it's asking me for a title, slab penetration.

02:56

Now the reason, we'll go and say this is a valid penetration.

03:01

And in the comments I'm going to say,

03:02

we haven't modeled the penetrations yet.

03:07

Now with this, I'm going to click OK,

03:09

and we can straight away see the total number of clashes

03:12

are reduced from 53 to 36.

03:16

This is where we can go to other clashes as well

03:18

and we can review them to decide whether they are real clashes

03:21

or we can convert them into non-issues.

03:24

Now to create issues, I'm actually

03:26

going to go into the other view.

03:28

Let me close out of this view.

03:31

I'm going to create a brand new view, and for that I'm

03:34

going to pick the 3D Electrical view coming from the Revit MEP

03:38

model and the Class Extension view from the Structure model.

03:45

I'll click on the clashes group by the electrical elements,

03:49

and now we've got this problem here to resolve.

03:53

So obviously we need to move these Troffer Corner

03:56

inserts down, but we don't know how much

03:59

we need to move them down.

04:02

And this is where we can use the measurement

04:04

tool available inside this interface.

04:09

Now before I start measuring the elements,

04:12

I'm going to modify my measurement settings,

04:14

make sure that Unit Type is set to the right units.

04:17

In this case, I want them to be in feet and decimal inches.

04:21

And now I want to find out what's

04:23

the distance between the bottom of this beam

04:26

and the top corner of this Troffer Corner insert.

04:31

So it's telling me that the z-value is 1 feet, 5.1 inches.

04:36

Similarly, if I go and check this one here, it's 9.1 inches.

04:42

So what we are going to do is create

04:44

issues to let people know how much these need to move down.

04:49

Now I've got two options.

04:51

One option is where I can create a single issue

04:55

to move all these elements down, or I

04:57

can create three separate issues,

05:00

one for each of these groups.

05:03

So I'm going to pick one, two, three, four elements,

05:08

and I'm going to go and click on Issue.

05:13

Now in this issues area here, I'm

05:15

getting asked to place a pin, so I'm

05:18

going to spin the model around and I'm

05:19

going to place the pin somewhere here.

05:23

The title for this issue is going to be Electrical

05:26

because that's the discipline, so I'm going to say E-L-E-C,

05:30

move the elements.

05:34

I'm going to assign it to this user here.

05:37

I want this user to fix it by Sunday because they've

05:40

got nothing else to do.

05:42

So I'm going to go into this date here,

05:45

and that's when they need to fix it by.

05:47

If I've got some location information,

05:49

I can enter this here in location

05:51

and also in location details area.

05:54

Root Cause is really important.

05:56

I'm a big fan of Root Cause, so I'm

05:58

going to call this as a design coordination issue.

06:01

And in the description area here, we

06:03

can add a description about how much

06:04

do we need to move these down.

06:06

So in this case, I'm going to go and say move this down by 156.

06:14

Now I'm going to go down and click the Create button.

06:19

It now goes and creates the issue,

06:21

and that particular issue is available on the Issues

06:24

panel on the left that we'll have a look at now.

06:27

As you could see, this is the issue that we have created.

06:29

If I click on this particular issue here,

06:31

it will take us to that issue.

06:33

One thing that I want to quickly show you

06:35

here is if I go to the Attachment tab here,

06:39

it would show me an image that it has automatically created

06:43

of this particular issue.

06:45

This image is really handy for the users

06:48

who are accessing the issue from the document management module.

06:52

I'll talk about this in detail in the next objective.

06:55

Let's now go back to our plushest panel.

07:00

So as you can see, those elements

07:02

are now removed from the clashes.

07:08

Similarly, I'm also going to create issues

07:10

for these group of Troffer Corners.

07:13

One of the questions that I get asked on a regular basis

07:15

is, you are creating these issues

07:18

and you're asking to move these elements down,

07:21

but what if there are ceilings here?

07:23

What are you going to do about them?

07:25

And this is where, again, the Model Coordination module

07:27

is absolutely fantastic.

07:30

What you could also do is, before you create your issues

07:33

you can add an additional module or a 3D view to make sure

07:37

that what you are advising is OK and the elements will not

07:41

clash with the other elements.

07:43

To do that, I'm going to go to the Models panel

07:47

and I'm going to click on this add/remove models button.

07:51

And in this case, I'm going to also add the architecture clash

07:55

detection view.

07:58

So what it's now doing is it's federating the architecture

08:01

clash detection view with our current view.

08:04

In this case, we can see that that would not

08:06

cause any of the clashes, again a really smart way of using

08:10

this technology to make sure that your advice is not going

08:13

to cause any other clashes.

08:16

I'm going to remove this architecture model

08:18

and now I can go and create issues with these items.

08:26

I'll assign it to the same user and make sure

08:29

that they work on the Sundays as well and fix this problem.

08:34

We'll make sure that we specify how much we

08:36

need to move these down.

08:39

And pretty much the same thing we can do for these elements

08:42

as well.

08:45

Just a reminder, I would strongly

08:47

recommend adding Root Causes as well,

08:50

because that way you can either filter the issues based on root

08:52

causes, or on the BIM 360 home page,

08:56

you can display dashboards with issues about root causes.

09:01

So that's how we manage the clashes

09:03

and we create issues using those clashes.

09:06

In the next objective, we are going

09:08

to look at how we can resolve these clashes by taking

09:11

this information into Revit and fixing these models there.

09:15

See you in that objective.

09:16

Cheers.
