Civil and Environmental Engineering

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!
