Perkins + Will

How will we generate the Alternative Solutions?

Case Studies • Help us understand the issues, technical

challenges, ideas and economics of the projects

Public Ideas • Ideas proposed by the members of the public and

past design proposals

How will we generate the Alternative Solutions?

Design Ideas • Six international design teams selected through a

competitive process to participate in an 8-week ideas generating exercise

• Two teams were assigned to each of three EA options: Improve, Replace, and Remove

• Detailed briefing on existing conditions and concurrent studies

• Feedback provided by stakeholder and technical committees mid-way through

• The complete design submissions are available for further review on our website

Questions for you to think about

• Which ideas are most consistent with your vision for the waterfront and the city?

• What ideas do you think are the most important to consider as part of the study?

• What ideas do you think are least important to consider as part of the study?
