SDSU Senior Design: Civil Engineering Building

Slide 1:

Presentation by Aztec Engineering Greg Favereaux Vu Nguyen Ivan Castro Marcus Albitre Nick Graziano San Diego State University Capstone Design Project

Scope and Purpose: The goal of our project is to design an ecologically green building to meet the requirements of the Civil, Construction and Environmental Engineering Departments for the next 20 years. Named Tonatiuh, the Nahuatl word for “Sun”, this ecologically friendly project that will provide San Diego State University with a 59,000 square foot Engineering Building that will be a jewel in the CSU engineering program, consisting of cutting edge classrooms and laboratories that will advance SDSU’s research goals while providing future engineers with a top quality education for decades to come. :

Site Selection:

Site Selection Four locations were considered for the placement of the building: Current Engineering Building Location A-LOT W-LOT X-LOT

Proposed Location X-LOT:

Proposed Location X-LOT X-Lot is the best compromise of all sites. There is more than ample space to meet the needs of the CIVE, CONE & ENVE for the next 20years. It has the least impact on the environment and displaces the least amount of parking, from the least used lot.

BUILDING SPECIFICATIONS:

BUILDING SPECIFICATIONS Total Building Size : 59,000 sqft Classroom Space : 32,000 sqft Laboratory Space : 20,000 sqft Office Space : 2,400 sqft Student Balcony : 2,750 sqft

Green Elements:

Green Elements Over 200 solar panels will generate 30,000W of electricity. A fiber optic lighting system to provide 3,000W of natural lighting. A length to width ratio of 1.7 for sunlight penetration and natural ventilation. A 340 cfs rainwater catchment tank to be used for flush toilets and irrigation Steel Frame consists of 25% recycled material. View from peak near X-LOT Adobe Falls

Slide 11:

Shallow Foundation Deep Foundation Which foundation???

Shallow Foundation:

Shallow Foundation The two main reasons: Lower cost. Faster to construct. Overall shallow foundations could not be implemented for Tonatiuh. The Issue: Load ranges: from 50 kips – 1,450 kips

Deep Foundation:

Deep Foundation Type: Drilled reinforced concrete piles. 20 columns total. Diameter ranging from 2-3.5ft. Depths of 35ft and 45ft Factor of safety (FS) FS > 2.5

Sustainability:

Sustainability Sustainability - “Capacity to endure” Triple Bottom Line - People Planet Profit

Triple Bottom Line:

Triple Bottom Line People : How will this project affect our neighbors in addition to benefitting the San Diego State student body? Site chosen with neighbors in mind Landmark for SDSU and San Diego Source of pride for Engineering students

Triple Bottom Line:

Triple Bottom Line Profit : How will it profit SDSU and local economy? Increased pride = improved recruiting More students in labs = increased research More research = increased grant revenue More college graduates = greater tax income for the state

Triple Bottom Line:

Triple Bottom Line Planet: What type of “environmental footprint” will we leave behind? Green aspects introduced = reduced emissions and cost savings Reduces flood impact of Mission Valley Uses recycled water/energy Estimated building usage: 50 years
