Civil and Environmental Engineering

Engineering the Future-2012

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. - 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 Torque Levers Friction Inclined planes Inertia Gravity

Resonance Metallurgy Seismology Work

Structural EngineersEngineering Terms:

Forces/gravity/inertia = Static and Dynamic Loads Torque/Levers = Moments, Torsion Friction/Inclined planes = Bolted connectors Metallurgy = Welded connectors Seismology = Earthquake loads Harmonics/Resonance = Dampening

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 Principals: Chemistry Biology Fluid mechanics (liquid and gas)

Geotechnical Engineers

• Soils

• Footings

• Foundations (shallow/deep)

Goal: To modify existing soil conditions to be suitable for engineering projects.

Geotechnical Engineers

Scientific Terms and Principals: 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 Principals: Hydrology Hydrogeology Fluid mechanics

Transportation Engineers

Goal: To safely transport people and goods.

Areas:• Planes• Trains• Automobiles• Public Transit• Ships• Rail

Joke: How many civil engineers does it take to build

a building?

Small Group Activity: • Bel Cheese is opening a manufacturing

plant in Brookings, SD. Brainstorm the different types of civil engineers that will be 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

Joke: How many civil engineers does it take to build

a building?

Answer: Almost all of them!
