Q

What are the challenges faced in organisation implementation?

A
  • Not enough training
  • Senior management to buy in
  • No external incentive to use BIM
  • Cost of Software
  • Mindset Change
  • CAD Evolution 01
  • Focus on drawings production
  • Project’s information in multiple files and formats
  • Difficulty to manage changes late in the design
  • Risk of data loss during multidiscipline coordination
  • BIM best practice and implementation strategies
  • Mindset Change
  • To many, even until today, still think BIM is an upgrade of AutoCAD mindset
  • A perception of drafting tools in 3D

Q

BIM Definition: Drawings

A

Drawings means two dimensional representations, hand sketches, perspective views or other graphical outputs printed physically or electronically.

As stated in revised Clause 1.10, Drawings will become part of the Model, thus there should not be a distinction between Model and Drawings.

This also results in the deletion of the clause stated in previous condition version, as clause on whether Model or Drawings prevail against each other is unnecessary.

Q

BIM Definition: Model

A

Model means a digital representation of the Project or part of the Project, and used to describe a two dimensional representation, three dimensional representation, as well as other data representations, including Drawings, as identified in the BIM Execution Plan.

The BPC V2 aims to redefine the meaning of Model, as it is possible to generate many types of data directly from the Model, including Drawings.

Instead of questioning whether a contractual deliverable should be in 2D, 3D, Drawings, BIM etc, the validity of the contractual deliverable should be determined by the content it represents.

Q

BIM Definition: Released Model

A

Released Model means a Model identified as such and released by the Model Author from time to time as agreed in the BIM Execution Plan.

Definition was previously changed from “Final Design Model” to “Released Model”.

It is possible that multiple Released Models may be made available at the same time.

The descriptions of each Released Model must be clearly documented in the BIM Execution Plan to avoid confusion to Model Users

Also note a Released Model may include two dimensional representations as well.

Q

BIM Definition: Model Author

A

Model Author means the party responsible for developing the specific content of a Model to the level of detail required for a particular purpose of the Project. Model Authors are identified in the BIM Execution Plan.

Key importance to note
Specific content of a Model
Particular purpose of the Project

As many information it to be embedded into a collaborative BIM modeling, different author uses the model and enter information at different phases for different purpose. This distinguish the model authorship and they shall be defined clearly in the BEP.
