Why Seattle Considered Alternative Approaches?
• Lack of Project Type Experience
• Experienced Private Vendors
• Potential Cost Savings
• Organizational Needs

• Looking for Improvements Over Conventional Design-Bid-Build
• State Statute

Alternative Models Considered

A Suggested DBO Project Philosophy
• Specify Performance Requirements• Integrated Vendor Teams Respond
• Encourage Technical Innovation• Use Competition in Innovation & Price
• Assign Risk to Party Best Able to Manage It
• Communications• Public/Stakeholders
• Elected Officials
• Culture of Partnership• Owner Sets the Tone

Better Contract Provisions Long Term Contracting
• Continue to Innovate• Incorporate Incentives into the Contract
• Provisions for Changing Needs• Primarily an Administrative Issue
• Focus Beyond Term of Contract• More than “end of term provisions”
• Asset Management• Consider ISO 55000• Or,… simply requiring annual Asset
