3. REDUCING RISK WITH BIM
1 What is Risk?
2 Technology Introduction
3 Construction Technology
4 Case Study: VA Puget Sound
5 Case Study: Stanford Cath Labs
6 Case Study: Robbins Hall
Renovation
4. WHAT IS RISK?
• Altering “Risk = Cost” Equation
• Increase in Architect’s Exposure
• Decrease in Contractor’s Risk
• Decrease in Owner’s Risk
• Reduced Risk for All = Reduced
Cost

6. Increase in Architect’s
Exposure
Unknown Consequences Of Sharing BIM
Information
Design Only Information In BIM Model
Extensive Pre-coordination
Fabrication From Design Models
Increased Exposure to Risk

8. Decrease in Owner’s Risk
Reduced Bidding Costs Due To Reduced
Contractor Risks
Reduced Risk Of
– Change Orders From Unknown Conditions
– Coordination Changes
– Fighting Among AEC Entities
Reduced User Changes Due To Better
Pre-visualization And Planning

31. Relative Sophistication Disparity
General Contractors (Very Low to Low)
Engineers (Very Low to Moderate)
Architects (Low to Moderate)
Subcontractors (Varies, some extremely high)
Maximize advantage of sophisticated players
Enhance process for Subs already using 3D
Mentor less advanced members

Editor's Notes
ADD IMAGEto produce clear documents, showing a buildable design.We use:Again, reliance on a coordinated and integrated team including the Cost Management consultant.And BIM allows us to make our documents fastidiously coordinated and accurate.The BIM model starts with the site and builds from there.The model is shared by all disciplines, and clash detection sessions are regularly scheduled throughout design and document production. We were early implementers of BIM in our industry and began with it 7 years ago.Quantity takeoffs are continuous, estimates revised all the time; major systems updates during design : mechanical & electrical, structural, site, building envelopeAlso take a friendly approach to the constructor to clearly indicate we want him on our team to build a successful project for everyone involved.
