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


Unknown Consequences Of Sharing BIM Information

Design Only Information In BIM ModelExtensive Pre-coordinationFabrication From Design Models

Increased Exposure to Risk

Increase in Architect’s Exposure


Reduced Coordination Errors Reduced Unknown Conditions More Efficient Workflow Cooperation & Collaboration Reduced Contingency

Increased Confidence & Reduced Risk

Decrease in Contractor’s Risk


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


Reduced Risk for All = Reduced Cost

Architect’s Exposure However

Architect’s Risk
