CM/GC Selection
– Phase I
• QBS or Best-Value
– Experience with construction of similar projects
– Estimating experience
– Innovation
– Phase II
• Negotiated price
–
–
–
–
Guaranteed Maximum Price (GMP)
Fixed Cost (lump sum)
Unit prices
Combination of the above
Phase II Negotiation
– Parties negotiated price & contract terms
• Minimize overall project risk
• Increase DBE participation
• Independent cost estimate (3rd party)
– If negotiations fail:
• Project goes to traditional design-bid-build
• CM/GC can not bid on the project
Outstanding Concerns
– CM/GC Selection Process
• Subjective
• No-bid contract
– Cost Validation
• Verify the price is acceptable to withstand public scrutiny
• What is the process for approving the price
• Will Mn/DOT negotiate in good faith
Implementation Process
– Step 1: Legislation
• Current legislation for CM at-Risk
– Excludes highway and bridge construction
– Not tailored to highway industry
• Requires new legislation
– Tailored to Mn/DOT
Implementation Process
– Step 2: Develop Process with industry
• Identify White Paper Topics
• Draft White Papers
– Step 3: Develop Manuals/Procedures
– Step 4: Identify Projects
– Step 5: Develop contracts
When to use CM/GC
– Not for every project
– Potential applications:
• Innovative construction techniques
• Complex staging/traffic control
• New materials/construction practices (ABC bridges)
