How Does It Work?
• MoDOT provides conceptual design
• MoDOT issues Request for Proposal
• Contractor team selected on “Best Value”
• Contractor completes the design and builds
the project in parallel instead of linear path

New Design-Build Model
• Streamlining internal approvals & reviews
• Flexible
• Limited requirements
– Meet federal design/construction standards
– Propose state design/construction standards
• Innovation and creativity of private sector
• Best value for taxpayers with maximum
improvements for the budget
