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

The Design Partnership LLP Architects + Planners
Reduced Coordination Errors Reduced Unknown Conditions More Efficient Workflow Cooperation & Collaboration Reduced Contingency
Increased Confidence & Reduced Risk
Decrease in Contractor’s Risk

The Design Partnership LLP Architects + Planners
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
