So what is this BIM
00:10
level of development?
00:11
Wait,
00:12
isn't it level of detail?
00:14
No, it's level of development.
00:17
Let's just get started with the general confusion.
00:19
When it comes to this acronym LOD,
00:22
there's two different LODs.
00:24
One is level of detail. That's the more popular assumption as to what LOD means.
00:29
And one is a level of development.
00:31
Both are LOD.
00:32
Right out of the gate, there's confusion - at
00:35
least I was confused.
00:37
I'll be honest, I get confused pretty easily.
00:39
So I'd rather you just tell me what you want me to put in the model and when you want it,
00:44
is that too much to ask?
00:47
Isn't using BIM supposed to make everything easier?
00:51
So here's the breakdown before I have a breakdown.
00:54
So what is the level of development?
00:56
The level of development is basically what needs to
00:59
be in the model at a specific milestone.
01:03
This is generally broken down by trade.
01:07
This will be consistent with the project milestones
01:09
agreed upon in the front end documentation.
01:13
This ensures that everyone stays on the same page and there's no surprises.
01:19
This is completely project specific.
01:22
Each project is going to have its own deadlines and milestones
01:26
and needs of level of development.
01:29
I like to
01:29
put these dates on everyone's calendar.
01:32
This is actually project management
01:36
level of detail.
01:38
This is what we're all more familiar with.
01:41
So what is the level of detail?
01:44
How much information is acceptable for this project?
01:47
On a scale from 100 to 501, 100 is a report or basic symbols,
01:53
calling out schematic design.
01:57
Level 200 means items are modeled but they're in there as placeholders,
02:01
they're not verified.
02:02
They might not be the right size, they might be floating around the floor.
02:10
Items modeled as designed with accurate dimensions.
02:14
All systems in level 300 are to be defined.
02:18
Level 350.
02:20
Well,
02:20
that gives us 300 plus clearances such as
02:23
no fly zones around mechanical or electrical equipment,
02:27
miscellaneous metals,
02:28
meaning angle iron, uplift, bridging, stuff like that,
02:32
reinforcing in concrete
02:35
hangers and brick and black cooing.
02:37
So 350 really drills in the specifics.
02:45
to be assembled as well as manufactured off site and installed on site.
02:50
This all needs to come from the model. If you're shooting for a 400 level of detail,
02:58
It's an as built condition as well as facility management info,
03:03
which is asset information
03:05
lockout tag out
03:06
or commissioning information.
03:09
In the next few videos, we'll look at how to bring all this stuff into context.
03:14
But what I like to say is try not to overthink this stuff. To be honest,
03:19
I think there's one too many committees overthinking this stuff as it is.
