This document discusses Building Information Modeling (BIM) and how it improves construction processes. It defines BIM as an intelligent 3D modeling process used in architecture, engineering, and construction. The document outlines the benefits of BIM such as clash detection, quantity take-offs, coordination, and prefabrication. It also discusses how BIM reduces waste and improves documentation, maintenance, and facilities management. Traditional construction methods are compared to digital construction using BIM. Finally, common BIM software, implementation around the world, and how to become a BIM professional are summarized.

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.

• 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.
