Final Presentation of Bay Architect Cindy Chan Engineer Yang, Yao-Hung Construction Manager David Walthall
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
Site Constrain • Earthquake Zone • Humidity Control -Sea Fog • Heating/Cooling Degree ( 1921/23 below 65 o F)
Architectural Constraint • 30’ height limit • Maintain the existing footprint, circulation and transportation route
San Francisco State University
Spine Project Information Resource Center Act of Recording, Analyzing, and Storing located at the spine area
Curve Project The curve generates the movement physically, visually, and conceptually
Structure Alternatives SPINE Core + Brace+ Steel SMRF CURVE Core +Steel MRF and lightweight concrete slab and steel deck
Structural Challenges • Steel SMRF system • Core wall Cantilever Part • Cantilever • Auditorium • Core wall Auditorium
Steel SMRF • Moment connection • W 24 resist two NS-EW seismic force W 24 x 229 I-Beam W 24 x 131 I-Beam
Core Wall • Connect with gravity system • C-shape core decreases torsion moment • Cast in place 10 inch core wall. • Share the vertical loading
Cantilever • Moment Connection 20 ft 10 ft • Sap Modeling 20 ft • Sap Modeling 10 ft span
Auditorium • Add balcony to increase seats
Modeling Curve with SAP 2000
Foundation 4 X 4 spread footing • Df square=4' (Depth under the soil) • Bsquare=3. 6' (Width of the footing) • Dthick=1' (thickness of the footing) – Water table - 16 -20’ – Soil Friction angle - 20 – Cohesion - 250 lb/Ft 2
Evaluation Pro A: Clear conceptual approach A: Multi spatial movement E: Uniform structural system E: Simple gravity system C: Large amount of repetition, symmetry C: Re-assembly of materials Con A: Lack of informal social space A: Exceeding height limit, form is too rigid E: Complicated concrete beams E: Eccentric moment issue C: Large amount of glass structure C: Non-Uniform beam
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

A+E+C Interaction- Auditorium. Structural A - 40’ span Supports MEP Location E – Curve wall and 2 columns inside the auditorium provide structural stability A – Column A+Mentor space become aisle. Circulation Idea: Balcony floor Security Issues
Auditorium - circulation
Roofing PV Modules – Photo Wall PV 75080 + Power Guard Structural system • Daylight: North facing roof monitor with clear glass panel • Energy: Photovoltaic panels facing south • Natural ventilation: Operable glass panel
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
Layout Crane Radius Site
Most Congested Concrete work done Total length of project = 8. 5 months
4 D Construction Sequence Sept Oct Nov Dec Jan
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

Projected Savings • Average Educational building consumes: 575. 3 k. Wh/day • 104 PV Panels generate 332. 4 k. Wh/day • At $0. 12 per k. Wh, building saves $958. 47 per day $349, 839. 86 per year
Computer Integrated A/E/C Take advantage from web based technologies – MSN – Net. Meeting – Email – Discussion Forums (PBL) – Group web space (PBL)
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
Lessons learned • Through sharing 3 D 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
