 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

BIM – a Cultural Change
• Much more than visualization
(renderings; animations; 3D CAD
representation) its thinking!
• An integrated planning, design
and construction process based
on an extensive digital database
• Special-purpose 3D/4D/5D
models built and documents
generated as needed
• Planners, designers
constructors and owners
have shared understanding
of project elements and
challenges
• Cross-disciplinary
collaboration reduces design
errors; avoids conflicts;
increases productivity; and
reduces risk and liability

The Evolution of Design & Construction
Today
Modeling (BIM)
Edges of pavement, sewer & water …
Visual models of objects and their parameters by discipline
– pockets of automation
Some transfer of models between disciplines, clash
detection, automated estimating take off, move to Design-
Build, occurrences of IPD
Complex discipline design problems and alternatives –
sustainability, supply chain schedule, Carbon footprint
Tomorrow
BIM
Digital prototypes of cities, regional developments, cloud
analysis
Visualize, simulate, analyze entire systems and delivery –
creator, consumer, community – supply chain
Interdisciplinary thinking with real time collaboration on
sustainable cities on central model servers (IPD, PA)
Whole scale multiple design approaches & alternatives
(Lifecycle cost analysis & tradeoffs)

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

Presentation Overview
 Use of Laser Scanning and BIM for
Documenting Existing Conditions
with 3-D Surveys
Process, Hardware/Software used
 Creating BIM Model of Existing
Conditions
 Application to New Work /
Modifications
 Reducing Risk for Stakeholders
 Lessons Learned / Future
Applications
Data Collection of
Existing Conditions &
Use of Data

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)

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)

Shift in Design Schedule
Rethinking How We Work
TRADITIONAL

BIM
DESIGN

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

Process: 3-D Survey of Existing Facilities
 Laser Scan Equipment
Set up at multiple locations
Overlapping views

Process: 3-D Survey of Existing Facilities
 Laser Scan Process
Set up at multiple locations
Overlapping views

3-D Survey of Existing Facilities
 Point Cloud
Millions of spatial data points
No intelligence

 Create 3-D Cad Model with No Intelligence

 Convert to Create BIM Model with Intelligence
Post processing used to will create line work from data points

Advantages
 Early Coordination among Disciplines
 Estimating Exact Quantities

Advantages
 Use by Construction Management for
Progress Tracking

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

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

Future Applications
 Scoping / Feasibility / Existing
Condition Studies
 New Industries (Aging
Transportation and
Infrastructure)
 Design / Build Projects
 Protecting Stakeholders
(Owners/Designers/Builders)
from surprises

Construction Simulation Movie

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.
• A195–2008, Standard Form of
Agreement Between Owner and
Contractor for Integrated Project Delivery

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?
