Building

Information

Model

(BIM)

Capitol Theatre, Edmonton, AB

• The BIM is a union or federation of many subBIMS or

BIMbits

• Each participant would own, maintain and be

responsible for their part of the BIM

• Models (if federated) or Worksets (if unified) are read-

write by the authoring party

• BIM is read-only by receiving parties

• BIM can be successfully shared along traditional

contractual structures

• BIM can be distributed

Changes & Risk

AIA E202 2008 as a Protocol

A/E’s own, maintain and are

responsible for the design portions and

design corrections to the BIM.

Contractors/Fabricators own, maintain

& are responsible for the built portions

and required modeling to the BIM

Designers are responsible for BIM

fidelity from LOD 100 – 300

Producers are responsible for BIM

fidelity from LOD 400 – 500

Can be safely federated or unified

inside BIM or 3rd Party federation

software such as “Navisworks”™

Engagement

Think of BIM as: Bim NOT BIM1. Data Centric versus Document Centric Thinking

2. Model only what needs to be modeled to create

an INFORMED interchange vs exchange milieu

3. Consistent, coordinated and complete BIM by

repeated communication and consultation

If BIM does not deeply

alter your core DNA

and profoundly change

your psyche then you

will not understand BIM

at all.
