How many words is a words is a model worth?
Models can be MUCH more than just a series of pictures They can represent:
• What if the model was produced by someone who is was a specialist?
• What if the author was non-specialist?
• What if the author was incompetent?
Introduction
BIM & CAD Basics
• What if the author was incompetent?
• What if the author was disorganized?
• What if the author was not yet finished?
What would be
communicated then?
Sample of difference in content between a specialist and a non-specialist. A non-specialist does not produce geometrically accurate models, but does indicate likely geometry.
The point is:
One of the largest challenges for the foreseeable future is managing the enormous influx of data.

Make sure that your team is communicating with relevance and effectively.
This Delta relates to the
cost & time needed to
produce subtrade
accurate drawings.

intended model will not work, all
effort is wasted and must be
repeated or abandoned.

Traditional CAD workers, and Modelers by habit grab a 300LOD content and attempt to finalize it to 400LOD. The final product was clean, crisp, timely, and never put through a clash review. Site determined success and managed the mistakes.
The Transition from 2D to 3D modelling.
The Effect On Traditional CAD Detailing
With BIM you have to break the habit of rush to 400LOD, and revisit the concept, making sure that the best intent has been found.
With BIM old habits need to be broken
24
The Construction industry as it now stands is more than 2 centuries old.
BIM by comparison, despite its decades of practice and theory, is still relatively in its infancy.

Panacea:
The goddess of
Universal remedy.
� BIM is Not Panacea
� BIM is best implemented by savvy Subtrades that are prepared to invest in an ongoing manner to maximize profit margins. If implemented and planned correctly the higher overhead, can be justified through cost savings.
� Any entity that views BIM as a band-aid or simple fix is likely dooming itself.

What needs to be in place?
� Any entity that views BIM as a band-aid or simple fix is likely dooming itself.
� Successful BIM implementation requires a thorough knowledge of technical, business and practical aspects and cannot replace the grail of experience.
� Failing to respect and plan BIM implementation would likely contribute to such downfall. It can be risky.
26
Don’t Let Anyone think that BIM is a panacea, Magic or Perfect:
� Not Corporate

� Not Project Management
� Not Site workers
� Not BIM staff
When does one start planning and setting up for a project/corporate adoption:

If BIM staff can’t set up the project, it’s a fight set up for a loss

Implementing BIM as a Mechanical Contractor
What needs to be in place?
Virtual Construction is not a single model. This is a huge point of risk.
� Full VC projects have multiple models from all major Consultants, Subtrades, Suppliers, and General Contractors. With each model representing the intent of it’s creator.representing the intent of it’s creator.
� Sub trades will absolutely have more than one model even if there are no other collaborators vacuum
� Manage the File Size & File Merge Line Risk

Data Storage & Filing Organization
Is one of the most critically important items no matter what level or CAD/BIM sophistication a company has. Whatever strategy is taken it MUST:

sophistication a company has. Whatever strategy is taken it MUST:
� Be intuitive
� Be organized
� Accurately track archived work (both internal and external content)

One of the most important yet difficult customers to win over to adopting a BIM strategy are site trades people.
� High knowledge/experience base
� High personal pride in work
� Very established methods of work and hierarchy

� Very established methods of work and hierarchy
As a result, tradesmen have much to offer to the process and much to gain, but may be very unwilling to accept new processes and standards. Prior experience with poor virtual construction implementations may further sour the process.

Come to terms with the fact that Implementing BIM will be challenging but possible.
There are 2 Options for implementation:
1. Cheap: Grow the BIM program organically with patience

What needs to be in place?
1. Cheap: Grow the BIM program organically with patience
2. Expensive: Go big, and solve it with money
Both will successfully gel with the realization that The BIM department core needs to have a very high level of Trade knowledge, and software knowledge.

1. Have a corporate Strategy and support

3. Have BIM leadership that understands the trade AND technology to a high level
4. Manage the LOD curve and risk constantly
