3. What is BIM?
• Building Information Modeling (BIM) is
an intelligent 3D model-based process
that gives architecture, engineering, and
construction (AEC) professionals the
insight and tools to more efficiently
plan, design, construct, and manage
buildings and infrastructure.

10. BIM Test – Is it BIM?
• Is Drawing in 3D BIM? – No
• Is Downloading CAD Drawings to Fabrication
Equipment BIM? – No
• Is linking Schedule (Time) to a Model BIM? –
Yes
• Is having product information in Model BIM?
- Yes

11. Key Concepts of BIM
• It is a Database – Not just 3D Drawings.
• It is all about sharing info through a Model with all
disciplines.
• Refers to a “Model” but it is a “Process” not a Product.
• Ultimate Communication Tool because it’s visual.
• Collaboration to the Nth degree
• Process + Tools = Power of BIM.
• Enabler for Lean Construction – can rely on Model to
help facilitate prefabrication.
• VDC (Virtual Digital Construction) + Analysis +Facility
Information = BIM

12. Why BIM?
Reduction of Waste - 31% of cost gets wasted.
• Correction/Re-work.
• Slowdown/Stoppages of Work Processes.
• Lack of Teamwork/Communication.
• Moving Materials on site.
• Inefficient Construction Methods.
• Waiting for Design Review Comments.
• Performing Work out of Sequence.

14. Advantages of BIM
• Automate Construction.
• Minimize Change Orders.
• Documentation.
• Reduce Co-ordination issues.
• Predictive Maintenance.
• Asset Tracking.
• Facilities Management.

15. Traditional vs. Digital Construction
Digital Construction offers the following
advantages:
• Clash Detection.
• Direct quantity Take-off.
• Drawings generated easily.
• Operation.
