BIM

COMMENT BY NOTE TAKER:
For those who attended this session, you may remember that the session discussion tended to be a bit chaotic and at times even heated.  The result was simultaneous conversations bouncing from the definition of “BIM”, the realities of “BIM” today, how “BIM” is being used to other tangential topics.  Needless to say it was pretty tough to get everything together on paper in a nice linear progression.   

So.........
I have decided to organize much of what was said into a few sections to help get a better understanding of the spirit of some of the major discussions in the session.

Cheers,
Chris Dizon


Part A
Example of SketchUp in “BIM”, presented by Hosted by mechanical eng

Easier to design plumbing in 3d... and with SU
Presentation of project examples:
    • Piping/Plumbing projects visualized in 3D.  
    • Use of sketchup as a “BIM” tool - Example: Through ruby/macros to build out data attribution.


Question: What is the deliverable?
Answer: Exported SketchUp model out to PowerCAD (dwg into PowerCAD)
Question:  Owners are wanting data sets for future management.... are you seeing that as a deliverable?
Answer:  I am not being asked for it.

Learning curve with SU helps get individuals into get up to speed quickly when in their initial training with his firm.

Part B
The many definitions of “BIM”

“BIM is like pornagraph, cant define it but you know it when you see it"

Is “BIM” a Noun or Verb?

There are various perceived pieces of “BIM”
BIM ==> 3D (first step)
BIM ==> Data attribution
BIM ==> Intelligence

“BIM is an instantiation of an agreed upon schema”

What is a practical BIM?
3d visualization of objects

Part C
Phil Reed - Revit & SketchUp

The goal of “BIM” is to create one data model to be accessed by many people and by many markets.  Is this actually possible?

Question: Should Google/SketchUp chase the BIM paradigm
..... if YES (SU as a “BIM” tool),  will SketchUp no longer be a viable useful design tool

Power of SU as a non “BIM” design tool:
........ SU is not parametric so it forces people to think more about the design.  Parametric models may result in “lazy” design

If 1 “BIM” model is not a realistic and viable expectation for projects, then “BIM” projects may contain 3 separate models:
- design model (intent model)
- construction model
- owner managed model

*********************************

BIM is needed to aid in the experimentation of the building before construction


Dangers of “BIM”
“....... garbage in equals garbage out”
“....... more implied in a 3d (BIM) model than a 2D
“....... “BIM has a long way to go”


If a project is made up of mutliple different data types (skp, dwg, rvt, dgn, etc).....
Who integrates the various designs (M/E/P) from the various contractors?
