BIM Me Up,Scottie! The Next Generation in Construction Technology
Agenda • What is BIM? • Current Practices • Benefits & Advantages • Challenges • The BIM Path • Case Studies • Summary
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
2D • Traditional drawings
3D • BIM
3D - Installed • Actual
4D Example • The Sundt Corporate Office
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
5D • Each component of the BIM tied to the Cost Estimate
Collaborated Model Arch Model (Revit) Struct Model (Revit) Civil Model (Bentley) Collaborated Model (Navisworks) Fire Model (CadPipe) Plumb Model (ABS) Elect Model (Graphisoft) Mech Model (CadDuct)
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
Benefits & Advantages • Clash Detection • Faster Construction Time • Streamline Delivery/Fabrication • Better Performing Facilities • Fewer Claims • Real Time Value Engineering • User Understanding – 3D Visualization
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
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
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
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.
Question: Yesterday vs. Today • Yesterday: When & why adopt BIM? • Today: How do we effectively deploy it?
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

Cronkite School of Journalism Mechanical Room (Is this going to fit?)
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
