Redesign- Sundial ProjectOriginal Concept• The Sundial will be a marker of time and
movement of the activities that occur inside the building
• Hallways acting like a Telescope (provide view to SF), allowing outsiders to have a clear view of the activities occurring inside.
Goal• Add Cafeteria and Gym
• Using the unique cone structure to centralize main social activity
• Provide more efficient circulation and
encourage interaction.

Attempt of Material Choice
A: Using Tensile structure for the cone structure
E: Concern about safety Issues: Wind velocity
Owner : Low R-Value for the tensile structure
Use double glazing for the
structure
A: short life cycle of the structural material

Construction Constraints and Considerations
• Site Location– Close to ocean
– San Francisco – seismic activity
– Metropolitan area – accessibility and construct ability
120 TonAll Terrain Crane
Grove GMK-5120B
For use with heavy columns And beams as wells as Decking
Reach of 72 feet to 115 feet. Heights from 52 feet to 72 feet. Lift capacities atmaximum reach of 1320 pounds to 2200
pounds. Maximum lift of up to 8800 pounds. For use with VRML
+ ’s - ’s
- Strong sense of directionality
- Clear frame and core defined
- Repetition, Symmetry
- Scarify large amount of space
- Complex interactions between systems
- Too Expensive
- Simple Form and Clear Circulation path
- Various informal social space
- Two Uniformed structure system
- Challenging Design
- Exceeding height limit
- The form is too Rigid
- Eccentric moment issue
- Amount of Glass
- Strong Form and Gesture
- Provide multi level special experiences
- Simple gravity system
- Reassembly of materials\
- Lack of informal social space
- Non-Uninformed Long beams
- Complicated concrete
Comments
Lessons Learned / ImprovementLessons
• Architect – Communication through 2D and 3D graphic program, Patient and Trust.
• Engineer – 3D coordination,Communication,
• CM – Complete Documentation exchange between discipline
Improvement
• Precisely define the size of components
• 3 D software modeling
• Always Keep other members inform of ideas, progress, and changes through website
• Time management and Efficient group meeting
