Rework Waste Prevention
• Coordination with existing conditions• Coordination between building systems• Increased systems awareness• Architects & Engineers (and sometimes
the contractor and subcontractors) communicate and share knowledge
Reduced waste of rework due to spatial coordination.

Construction Waste Prevention
• Material efficiency algorithms• No part duplication/no lost parts• Reduced labor with direct fabrication• No storage/ just-in-time delivery• Prefabrication labor in shop
Reduced waste of due to field labor.

Relative Sophistication DisparityGeneral 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 Integrated Project Delivery

3. “Risk = Cost” Equation
• Decrease in Contractor’s Risk• Decrease in Owner’s Risk• Increase in Architect’s
Exposure• Reduced Risk for All = Reduced
Cost

The Big BIM/IPD/Lean Idea
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 Bids 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
