Engineering the Future-2014
What is Civil Engineering?
Civil engineering is the design and maintenance of public works such as roads, bridges, water and energy systems as well as public facilities like ports, railways and airports. – American Society of Civil Engineers (ASCE)
What does a civil engineer do?
Civil Engineers
• Structural Engineer
• Environmental Engineer
• Geotechnical Engineer
• Transportation Engineer
• Hydraulic Engineer
Structural Engineers
Scientific Terms and Principles:
Forces Gravity Inertia Newton’s Laws Torque Levers
Friction Inclined planes Metallurgy Resonance Seismology Work
Structural EngineersEngineering Terms:
Forces/gravity/Newton’s 3rd Law = Static and Dynamic Loads, Support Reactions Torque/Levers = Moments, Torsion Friction/Inclined planes = Bolted connectors Metallurgy = Welded connectors Seismology/Resonance/Newton’s 1st and 2nd Law = Earthquake loads, Dampening Work = Deflection characteristics
Structural Engineer
The goal of every structural engineer is to design a safe and efficient structure.
Bridges
Buildings
Environmental Engineers
Areas: • Water treatment• Wastewater treatment• Air quality• Distribution systems
Goal: To provide safe resources from nature, and to safely return used resources to nature.
Environmental Engineers
Scientific Terms and Principles: Chemistry Biology Fluid mechanics (liquid and gas)
Geotechnical Engineers
Examples:
•Soils
•Footings
•Foundations (shallow/deep)
Goal: To modify existing soil conditions to be suitable for engineering projects.
Geotechnical Engineers
Scientific Terms and Principles: Geology (Soil mechanics) Hydrogeology (Ground water) Fluid mechanics
Hydraulic Engineers
Goal: To safely control the flow of water in both natural and man-made waterways.
Examples:• Dams• Levees• Drainage channels• Canals• Irrigation
Hydraulic Engineers
Scientific Terms and Principles: Hydrology Hydrogeology Fluid mechanics
Transportation Engineers
Goal: To safely transport people and goods.
Areas:• Planes• Trains• Automobiles• Public Transit• Ships• Rail
Transportation Engineers
Scientific Terms and Principles: Geometry Probability & Statics Geology (soil mechanics)
How many civil engineers does it take to build a
building?
Small Group Activity: • Bel Cheese recently opened a
manufacturing plant in Brookings, SD. Brainstorm the different types of civil engineers that were involved in the project before, during, and after construction.
Before
• Land Surveyor - Site topography• Geotechnical - Soil tests and foundation design• Structural - Building and internal structure
design. • Environmental - Water and wastewater system
design• Transportation – Mobilization of materials,
parking lot design
During
• Geotechnical - Consultation
• Structural - Consultation
• Environmental - Consultation
• Transportation - Moving construction materials to the site
After
• Structural - Design of manufacturing structures and components
• Environmental - Water treatment (in), air treatment and waste treatment (out)
• Transportation - Moving goods
How many civil engineers does it take to build a
building?
Answer: Almost all of them!
