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 Engineers Engineering Terms:  Forces/gravity/Newton’s 3 rd Law = Static and Dynamic Loads, Support Reactions  Torque/Levers = Moments, Torsion  Friction/Inclined planes = Bolted connectors  Metallurgy = Welded connectors  Seismology/Resonance/Newton’s 1 st and 2 nd 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!
