  2. Agenda • Project Introduction • Four Preliminary Design Alternatives • Final Design - A / E / C Solutions and Interactions • Learning Experience

  3. Introduction • Building for Riverbank University in Sacramento • Virtual Project (Year 2010) • Produce 4 Alternatives and 1 Final Design • Practice A/E/C Interaction

  4. Requirements • Architectural Requirements • Maintain Footprint & Transportation / Circulation • Occupancy, Security, Environmental (3 stories, total height 35’) • Structural Requirements • Load: Earthquake and Total Height of 35’ • Construction Requirements • Budget : $5,500,000 (Structural $550,000) • Time Budget : 12 months (ready in May 2012)

  5. 4 Alternatives 1 2 3 4 $4,500,000 $4,900,000 $4,700,000 $4,100,000

  7. Alternative 1

  8. Alternative 1

  9. Alternative 2

  10. Alternative 2

  11. Alternative 3 3rd floor

  12. Alternative 3

  13. Alternative 4

  14. Reasons for choosing Alternative 2 • Owner’s Decision Aesthetic and Challenging Design • Team’s Preference Attracting Glass Atrium Challenging Structural Systems Feasible in Time and Cost

  15. Further Iterations and Evaluations A Meeting with Owner • Height Limit • Faculty Lounge • Atrium Design • Structural Materials Revised design Feedback on cost Revised design material choice Suggestions and changes E C Revised design Feedback on cost and constructibility

  16. Discussion on Faculty Lounge

  17. Discussion on Structural Materials • Prefab Steel Frame for Atrium • Cast-in-place Concrete Columns
