Winter Proposal: Square Base Slender Roof Framing Traditional Framing System “Table Top” Stable Platform Concept: Golden Section Rotating Squares Defies Gravity Structural and Construction Feasibility Cost: Year 2015

Winter Proposal: Double Square Base Structural and Construction Feasibility Concept: Golden Section Rotating Squares Defies Gravity Cast-in-Place Frame 10” Shear Wall 12” x 12” Columns 10” Inclined Slab in Auditorium Cost: Year 2015

Design Matrix SQUARE BASE DESIGN Strong concept and space planning well integrated with the structural system. Looks complicated but can be build with current equipments and tools.

Unconventional design approach - Building on piers to minimize hydraulic impact. - Flexible floor space. Design Approach To create an innovative building and environment that nurtures the minds and spirits Extending artificial outdoors. Sustainable design.

Design Approach A suspended glass building that defies gravity.

Design Concept Using the Golden Section and Rotating Squares to create innovative spaces and environment Golden Section Rotating Squares

Upgrade Options Aesthetic Improvement: Upgrade interior finish in 2 nd and 3 rd floor circulation areas –California Gold Slate tiles- $7/sf –Add $44,800 (6400 sf) Reduce Life-Cycle Costs: –PV cells on roof and solar electric generator –Initial Cost: $5/watt ($1.8m, $60,000/year over 30-year period) –Life-Cycle Savings on Power: $15/watt (over 30 yrs) –Total Savings: $3.6 million for 12kW Building

Team Interaction: Winter vs Spring Winter Quarter (Schematic Design Phase) o Group Interaction o Synchronous Emphasized o Multiple Iteration o Very Loose

Team Interaction: Winter vs Spring Spring Quarter (Construction Document Phase) o Mentor interactions o Asynchronous professional work o Multiple synchronous integration o Professional design development

AEC Interaction - Framing Architectural Schematics is completed Budget way too high! Can we move to a steel frame? Steel framing is good - I need to reorganize the bay system I have to adjust the 1 st Floor plan to suit the new bay system. I want to erect the steel members before placing the decking. I am concerned about deflection caused by your proposed sequence.

AEC Interaction - HVAC Owner concerned about MEP options Develop MEP requirements Investigate current restrictions Present problem to team A – Sustainable design can decrease demand E – External ducting allow for flexibility C – Radiant heat can increase interstitial space Owner still smiling

Conclusions and Recommendations Lessons learned: Better and faster decisions can be made during Schematic Design Phase using AEC Integration method. Technology can be a powerful tool… when it works. How it can be improved: Critical that A-E-C students be exposed to collaborative tools and methods during their tertiary education. Future prospect: Collaborative design-build has tremendous potential, but limited now by design accountability. A-E-C Integration
