  1. Final Presentation of Bay Architect Cindy Chan Engineer Yang, Yao-Hung Construction Manager David Walthall

  2. Project Introduction • Engineer School of the Bay University in San Francisco • 3-story building with a total of 30,000 sq. ft • Provided innovative facilities with access to Internet and Telecommunication

  3. Site Constrain • Earthquake Zone • Humidity Control -Sea Fog • Heating/Cooling Degree ( 1921/23 below 65 o F)

  4. Architectural Constraint • 30’ height limit • Maintain the existing footprint, circulation and transportation route

  5. San Francisco State University

  6. Spine Project Information Resource Center Act of Recording, Analyzing, and Storing located at the spine area

  7. Curve Project The curve generates the movement physically, visually, and conceptually  

  8. Structure Alternatives SPINE Core + Brace+ Steel SMRF CURVE Core +Steel MRF and lightweight concrete slab and steel deck

  9. Structural Challenges • Steel SMRF system • Core wall • Cantilever • Auditorium • Steel SMRF system Cantilever Part • Core wall Auditorium

  10. Steel SMRF • Moment connection • W24 resist two NS-EW seismic force • W24x229 I-Beam • W24x131 I-Beam

  11. Core Wall • Connect with gravity • system • C-shape core decreases torsion moment • Share the vertical loading • Cast in place 10 • inch core wall.

  12. 20 ft 10 ft Cantilever • Moment Connection • Sap Modeling 20ft • Sap Modeling 10ft span

  13. Add balcony to increase seats Auditorium

  14. Modeling Curve with SAP 2000

  15. Foundation • Df square=4'  (Depth under the soil) • Bsquare=3.6' (Width of the footing) • Dthick=1' (thickness of the footing) 4X4 spread footing • – Water table - 16-20’ • Soil Friction angle - 20 • Cohesion - 250 lb/Ft2

  16. Evaluation Pro A: Multi spatial movement E: Simple gravity system C: Re-assembly of materials Con A: Lack of informal social space E: Complicated concrete beams C: Non-Uniform beam Pro A: Clear conceptual approach E: Uniform structural system C: Large amount of repetition, symmetry Con A: Exceeding height limit, form is too rigid E: Eccentric moment issue C: Large amount of glass structure

  17. Vision of the Engineering Building • Encourage informal social interaction between faculty and student • Ecological and Climate Responsive design to maximize building life cycle, increase user comfort and save energy cost

  18. 1st Floor Parking 2nd Entrance Main Entrance

  19. 2nd Floor

  20. Open Student Discussion Space Cantilever Structure 2nd Floor Balcony

  21. Basement

  22. Section Faculty Office S. Class Room Auditorium Comp. Lab

  23. A+E+C Structural Supports MEP Location Interaction- Auditorium A- 40’ span E– Curve wall and 2 columns inside the auditorium provide structural stability A– Column space become aisle. Idea: Balcony floor A+Mentor Circulation Security Issues

  24. Auditorium - circulation

  25. Roofing • PV Modules – Photo Wall PV 750-80 + Power Guard Structural system • Daylight: North facing roof monitor with clear glass panel • Energy: Photovoltaic panels facing south • Natural ventilation: Operable glass panel

  26. HVAC Thermal Mass Curve and West wall are Built by mass concrete wall to Minimize AC Controlled AC zone, Bring in outside cool air • Natural Ventilation • Between Floor slab • Large open Window

  27. Layout Crane Radius Site

  28. Most Congested Concrete work done Total length of project = 8.5 months

  29. 4D Construction Sequence Sept Oct Nov Dec Jan

  30. Budget Factors • San Francisco area factor of 124% • Inflation of 2.5 – 3 % Translates into a 5.5 million dollar donation in 2015 being worth 3.2 million dollars in 2001

  31. Budget

  32. Budget Access flooring Mechanical Fire Protection Electrical Plumbing

  33. Projected Savings • Average Educational building consumes: 575.3 kWh/day • 104 PV Panels generate 332.4 kWh/day • At $0.12 per kWh, building saves $958.47 per day $349,839.86 per year

  34. Computer Integrated A/E/C Take advantage from web based technologies • MSN • NetMeeting • Email • Discussion Forums (PBL) • Group web space (PBL)

  35. Group Assessment • Collaborative Inadequacies • Need to have more portions of product model shared • Time Control • Collaborative Successes • Strong integration of structure and architecture on design stage • Friendly relationship • Systematically achieve project requirement through interactive design process

  36. Lessons learned • Through sharing 3D models • Save time and increases efficiency • Easily to figure out and solve conflictions • Everyone should use compatible technology • Formatting correct communication protocols • Understand what other discipline needs • Properly propose what you need • Take necessary courses needed

  37. Thank you.. Mentors
