Start with a Quiz!

(without prizes…)


What LOD?

Titel van de presentatie

It is about trust/reliability


LOD’s

No clear definition

Nobody knows what it should be

Everybody knows what it should be


Everybody has their own definition


What do you need?

To perform a task, at a given time?


A project!


Looking at ‘LOD’-levels in different countries


Looking at Dutch created levels (by companies)


Even trying to find an LOD in files….


But it is all about:What do you/I need?

To perform a task, at a given time?


BIM informatieniveaus


So….….


We need to know more….

How does that look?


1. The base: information matrix

2. The projecttemplate

Template is the core of usage in a BIM collaboration.

Therefore we made it part of www.bimprotocolgenerator.com

(and also other parts of the National BIM Guidelines for the Netherlands. For

example ‘BIM and legal aspects’; ‘IFC exchange’; etc)


3. Guidelines for use: examples

Work in progress

MEP is not good enough yet

Infra is in there, but only from one company

Future work:

Connecting with objectlibraries


Interesting

Very similar levels as in like Denmark, UK, etc..

Very similar concept to bimforum LOD (developed parallel)


It is about trust/reliability/confidence

“Does this model hold the information I need?”“Where can I use this model for?”


Interesting

It is not about the geometry

Geometry is also ‘just’ information

In many cases ‘the other’ does not need the geometry information
