6. Challenges
• Four Billion more people
• Infrastructure failing ($40T WW)
• Transportation needs expanding
• Funding Gap (~$20T WW)
Reactions
• Re-focusing - from dispersed habitation to urban infill
• Rising of the 3 R’s – Repair, Recondition and Retrofit
• A Greener Planet - Resilient Infrastructure, optimized
mobility & green buildings
• Outcome vs prescription based requirements
14. Success Awaits
“The company spent $40,000 to create the models, but identified more than
$150,000 in system clashes. Requests for information were reduced
by 75%, with zero change orders.
The 12 people who worked on the model during preconstruction saved the
work of dozens in the field later, reducing the schedule by 18%.”
- Dan Klancnik, VDC Manager
The Walsh Group

17. What is BIM?
BIM = Building Information Modeling
3-D CAD w/ Intelligence; not just line work
Collection of objects with editable attributes
Can include: Size, Material, Specs, When Installed,
Cost
Database Driven
Models for Each Design Discipline
Master Model for Extractions
Views or slices of the model (Data extraction
from objects (i.e. material takeoffs)
18. Establishing a 3D Database of Existing Conditions
Application: Lack of “As Built” Documentation
Less time playing catch up
3D Database of Existing Conditions
Complete Set of Data
No more repeated reviews of existing conditions as needed
during design; all there at beginning
No additional CAD costs
Same effort required; just moved to front of project
Design, Construction, Building Management Tool
Best of Both Worlds
Still use traditional presentation methods (2-D dwgs)
along with new ones (i.e. 3-D PDF interface / output)
19. Shift in Design Schedule
Rethinking How We Work
TRADITIONAL
DESIGN
BIM
DESIGN
20. Shifted Design Schedule - Challenges
While same overall effort is expended, labor is moved
to beginning of project for surveying and design
Higher rate of labor burn early in the project.
Early decision making crucial
Difficult to make major changes late in project

23. 3-D Survey of Existing Facilities
Point Cloud

No intelligence
24. 3-D Survey of Existing Facilities

25. 3-D Survey of Existing Facilities
Create 3-D Cad Model with No Intelligence
26. 3-D Survey of Existing Facilities
Convert to Create BIM Model with Intelligence
Post processing used to will create line work from data points
32. Lessons Learned
Ensure sufficient level of detail is specified for
3-D surveys
Obtain plenty of views/scans
Allow time for post-processing raw survey data
Establish CAD layering early
Define BIM model objectives
Phasing: temporary, interim and final
33. Reducing Risk to Stakeholders
Accurate existing condition information from
the beginning
Effective communication and visualization tool
for all parties
Identify conflicts / potential problems very early
in design
Ensures coordination between disciplines
Accurate estimates
Allows Designer, Client and
Contractor a full understanding
of the project
34. Future Applications
Scoping / Feasibility / Existing
Condition Studies
New Industries (Aging
Transportation and
Infrastructure)
Design / Build Projects
Protecting Stakeholders
(Owners/Designers/Builders)

The AIA IPD Guide identifies the characteristics of IPD and provides specific
information and guidance on how to utilize IPD methods to achieve enhanced design,
construction and operations processes.
Integrated Project Delivery (IPD) leverages
early contributions of knowledge and
expertise through the utilization of new
technologies, allowing all team members to
better realize their highest potentials while
expanding the value they provide
throughout the project lifecycle.

The AIA BIM Protocol is a practical tool for using BIM across all phases of a project.
It also defines the extent to which downstream model users, such as contractors and
fabricators, can use and rely on the model for scheduling, pricing, fabricating and
construction.
• Who is responsible for each element of the
model and to what level of development?
• What are authorized uses for the model?
• To what extent can users rely on the model?
• Who will manage the model?
• Who owns the model?
