What Is BIM?
5
Definition

• BIM is the move from analog to digital design and
  construction. A model-based technology linked
  with a database of project information - AIA

• Construction is the only industry that does
  not/cannot test a design before production

6
2D vs. 3D
7
2D

• Traditional drawings

8
3D

• BIM

9
3D - Installed

• Actual

10
4D Example

• The Sundt Corporate Office

11
4th Dimension - Time

• Each element in model tied to CPM Schedule
• Construction sequence can be simulated showing
  conflicts between trades
• Play What if? game with model to find more
  efficient construction path - saving time and
  money
• Once construction begins model used to track
  construction progress

12
5D

• Each component of the BIM tied to the Cost
  Estimate

13
Current Practices
14
Collaborated Model
Struct Model (Revit)
Arch Model (Revit)
Civil Model (Bentley)
Collaborated Model (Navisworks)
Fire Model (CadPipe)
Plumb Model (ABS)
Elect Model (Graphisoft)
Mech Model (CadDuct)
15
Model Changes

• The ability to change the model is strictly
  limited to those who are responsible for changes
  to that portion of the model
• A precise audit trail can be maintained

16
BenefitsandAdvantages
17
Benefits Advantages

• Clash Detection
• Faster Construction Time
• Streamline Delivery/Fabrication
• Better Performing Facilities
• Fewer Claims
• Real Time Value Engineering
• User Understanding 3D Visualization

18
Challenges
19
Challenges

• Lack of standards for organization and format of
  data contained within the model
• Contracts/Delivery Methods
• Defining responsibility
• Allocation of Risk
• Ownership of data
• Insurance/Surety/Bonding
• Interoperability
• Fear of change
• Initial investment costs
• Learning curve

20
Challenges For Designers

• Change in culture work flow
• Work is divided up by major building elements in
  lieu of by drawing sheets
• Decisions are made earlier as to materials,
  specifications and quantities

21
The BIMPath
22
First Steps

• Get Senior Management involved to ensure
  leadership support
• Dedicate someone to the effort BIM Champion
• Prepare a BIM plan keep it simple and specific

23
Learning Curve

• It is generally accepted that there is an initial
  cost and loss of productivity while obtaining the
  necessary resources as firms go through the
  initial learning curve.
• Those firms who have made it through this initial
  learning curve (on average between 6 and 18
  months) experience the benefits.

24
Question Yesterday vs. Today

• Yesterday When why adopt BIM?
• Today How do we effectively deploy it?

25
Software Training Cost

• Design Software 3,200.00 /- per user
• Navisworks 8,000.00 /- per copy
• Training

Case Studies

• Sundt Office Building
• Cronkite School of Journalism, ASU
• Butler Treatment Plant

Butler Treatment Plant

• Sequenced Work

31

33
Cronkite School of Journalism

• Level 1 Fire Protection Clashes
• Orange Ductwork
• Red Mechanical Piping

34
Cronkite School of Journalism

• Mechanical Room (Is this going to fit?)

35
Summary

• Use of BIM is leading to a revolution in project
  delivery and facility maintenance.
• The traditional tri-party approach to design and
  construction will, over time, be replaced by
  Integrated Practice and collaboration

Examples

• Cityscape Construction Timeline
• Cronkite School of Journalism
