AEC Industry• Lot of Casualties…
– Poorly Coordinated Design Documents– Change Orders & Rework – Delays & Cost Overruns– Claims & Litigation– Greater Risk– Poor Turnover Documents– Frustrated Owners– Tight Profit Margins
State of the AEC Industry
AEC Industry• Demand for Better
Sustainability– Construction process> 20%
waste– Buildings consume 60% of
US raw materials– Buildings consume 40%
world’s energy (poorly)• Requires coordinated,
collaborative effort
Center for Excellence for Sustainable Development• Buildings consume 40% of
world’s energy*• 81 million buildings currently
operating in US• Over 30 million more forecast
to start design between 2005-2010
(*Roodman and Lenssen summary on impacts of buildings)
State of the AEC Industry
AEC Industry• Summary…
– $4T industry with > 20% waste (at least)– Buildings consume 60% of US raw materials– Buildings consume 40% world’s energy (poorly)– Projects routinely exceed schedule/budget– Claims and litigation– Low profit margins– Declining productivity– Depleting workforce
• Antiquated processes and tools
State of the AEC Industry
But….. • A major wave is forming
that WILL dramatically change the AEC industry
State of the AEC Industry
BIM• Building Information Modeling
– Enabled by powerful technology– Facilitated by collaboration and
integration
State of the AEC Industry
BIM• Bottom-up, not top-down
– Driven by industry practitioners who see the value
• Important to understand why it is valuable– It will become pervasive– Building Design, Construction,
Development, Ownership and Management will change
BIM: What It Is and Why It’s Important
• BIM is to CAD…• …as CAD was to manual drafting with Ink and Linen
BIM: What It Is and Why It’s Important
BIM is an interoperable database
• Multiple models interoperate– Architectural model– Structural model– HVAC model– Piping model– Telecommunications model– Electrical model– Furniture model– Civil model– Construction model– Fabrication model– Facility management model– etc.
The ability of a system to work with
other systems without
special effort on the part of the customer.

BIM: What It Is and Why It’s Important
BIM is an interoperable database
• Models can interoperate with analysis and other specialty tools – Rendering, 3D Printing– Scheduling– Estimating, Procurement– Engineering Design– Animation, Simulation (construction, energy consumption, etc)– Laser Scanning and Underground Radar– Facility Management
BIM: What It Is and Why It’s Important
• Graphical Information– 3D Objects Visual in the Model –
Architecture, Structure, Ductwork, Piping & Equipment
• Non-Graphical Information– Performance Data
• Linked Information– Schedule & Cost Information
It is all about the Information …

As-Built Model:• Owners receive a “digital double” with Asset information
embedded in the BIM Models.
What this means for BPMs
“When you design a building using [BIM]
Larry RochaWimberly Allison Tong and Goo
you create an intelligent data model of the building that can be used more effectively than standard two-dimensional documents.”
What this means for BPMs
“When you provide Building Product Models
Marc Goldman
you offer intelligent representations of your products that are more valuable to your customers than traditional product information which can provide a competitive edge and help you get spec’d.”
What this means for BPMs
BIM Content is:
In high demand by BPM customers!
Easier to use for design, take-offs, estimate and specification!
Being provided by a couple hundred BPMs!
What this means for BPMs
One Building Product Model contains multiple views (2D and 3D)
What this means for BPMs
Building Product Models are comprised of the “parts & pieces” of your product systems
What this means for BPMsWhole systems of parts with multiple
options and configurations
What this means for BPMs
Not just architectural products…Not just architectural products…
What this means for BPMs
Building Product Models aware of their required clearances.
What this means for BPMs

Fully Parametric:Can control size and many details.

What does this mean for Owners
BIM can be used as a database throughout the life of the building
• Generate as-builts for tenant build-outs• Recall the paint color of the accent wall in the
executive conference room• Calculate the square footage of the same wall• Better adherence to design standards & aesthetics
What does this mean for Owners
BIM can enhance a building’s performance and provide operational efficiency throughout its life
• Better asset tracking & mgmt• Better maintenance (warranty, failure, support)• Better adherence to design standards & aesthetics
What does this mean for Owners
What should building owners should do
• Define BIM Standard which AEC stakeholders must adhere to
• Utilize BIM content which is populated with BF Saul valuable data
• The BIM model must be kept alive after the model is handed over to BF Saul
• Manual data entry will be necessary to maintain the most up-to-date information in the models
This is a fantastic time to be entering the [Building Industry], because [the Building Industry] is going to change more in the next 10 years than it has in the last 50. Bill Gates*
We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. Don't let yourself be lulled into inaction. Bill Gates
Things to Think About
If you don't like change, you're going to like irrelevance even less.Ret. General Eric Shinseki, Chief of Staff, US Army
