Levels of BIM maturity

Question 1

What is level 0 BIM?

Answer 1

The simplest level of BIM maturity
Simple 2D drawing
Output and distribution is via paper or electronic parts

Question 2

Does the industry still use level 0 BIM?

Answer 2

No, the majority is ahead of this now

Question 3

Is there any collaboration in level 0 BIM?

Answer 3

No

Question 4

What is level 1 BIM?

Answer 4

Mixture of 3D CAD for concept work, and 2D for drafting documention for final production info.

Question 5

How is electronic sharing of data carried out in level 1 BIM?

Answer 5

From a common data environment (CDE) often managed by the contractor.

Question 6

Is there collaboration in level 1 BIM?

Answer 6

None or partial collaboration between disciplines.

Question 7

What is level 3 BIM?

Answer 7

Full integration and collaboration between all disciplines by means of using a single, shared project model.

Question 8

How does level 3 BIM have the benefit of removing risk of confilicting information?

Answer 8

All parties can access and modify the same model.

Question 9

What level of BIM has the UK government reasserted its commitment towards?

Answer 9

Level 3 BIM

Question 10

What is level 4 BIM?

Answer 10

By data mining and applying algorithms, buildings can be designed to be more attuned to the communites demands.

It will become rapid, semi-automated

Question 11

What is ‘lonelyBIM’?

Answer 11

When you build a model in REVIT and generate drawings from it.

Very useful to analyse a building and generate drawings, but not in the true spirit of BIM.

Question 12

What is a federated model?

Answer 12

A combined/merged Building Information model that has been compiled by combining several different models into one.

Question 13

What does ‘CDE’ stand for?

Answer 13

Common data environment. An online place to collect, manage and share information among your team.

Question 14

What are the benefits of a federated model?

Answer 14

Earlier design developments on key decisions with 3D info.

Clash detection

Improved estimations.

Question 15

What is a Federated Model in BIM Level 2?

Answer 15

A combination of individual discipline models that are brought together without directly interacting.

Question 16

Do individual models in BIM Level 2 interact with each other?

Answer 16

No, they do not interact; they are separate and only supply data for the Federated Model.

Question 17

How does the Federated Model affect liability in BIM Level 2?

Answer 17

Liability for model suppliers remains similar to traditional working methods, as models are distinct.

Question 18

Why is liability unchanged in BIM Level 2?

Answer 18

Because individual contributors retain control over their models and do not directly alter others’ work.

Question 19

How is data shared in level 2 BIM?

Answer 19

Through a common file format using a common data environment.

Question 21

What major change is expected in BIM Level 3? (federated)

Answer 21

The move to a single, integrated online project model accessible by all participants.

Question 22

What is a key difference between BIM Level 2 and BIM Level 3?

Answer 22

BIM Level 2 uses separate models; BIM Level 3 involves a shared, collaborative model.

Question 23

What contractual challenges might arise in BIM Level 3?

Answer 23

Defining responsibilities and liabilities in a shared model environment.

Question 24

How might copyright be affected in BIM Level 3?

Answer 24

Shared contributions could blur ownership, making copyright management more complex.

Question 25

What legal consideration becomes more important in BIM Level 3?

Answer 25

Ensuring clear contracts to handle shared access, edits, and model contributions.

Question 26

Why is careful contractual planning essential in BIM Level 3?

Answer 26

To address new issues in liability, ownership, and collaboration within a single model.

Question 27

A 'clash' is not the failure of the designer, what is?

Answer 27

Not spotting one

Question 28

If clashes were missed, and only spotted during construction, what could this result in?

Answer 28

Potential for huge costs and delays.

Question 29

Why is BIM clash detection good?

Answer 29

Clashes can be found earlier, making it easier, cheaper, and less time to rectify.

Question 30

What is a 'hard' clash?

Answer 30

When 2 components occupy the same space. For example, a column running through a wall.

Question 31

What is a 'soft' clash?

Answer 31

When an element isn't given the spatial or geometric tolerances it requires. e.g. air condtioning.

Question 32

What is a 4D clash?

Answer 32

The shceduling of contractors, delivery of equipment and materials, and general timeline conflicts.

Question 33

What is an acceptable clash?

Answer 33

A geometric clash that is acceptable. For example, a pipe passing through an RC beam.

Question 34

How are clashes resolved?

Answer 34

Running a clash detection scan. Reviewing and cancelling these clashes.

Question 35

What is the improvement with level 3 BIM for clash detection?

Answer 35

One collaborative, co-ordinated building means that clashes are dramatically reduced.

Question 36

What is level 2 BIM?

Answer 36

Where all parties use their own models to create a federated model.

Question 37

What year did the UK government set all parties to be working at level 2 BIM?

Answer 37

2016
