Introduction to Civil Engineering

1

What is EngineeringThe word engineer originates from theLatin term ingenerare, meaning toinvent, to create or to regulate

It is the professional art of applying scientific principles to every day things to help make life easier

2

Engineer vs. ScientistDeviations between engineers and scientists arise through the differences in the ways both apply their educations in mathematical and natural sciences to their work

ScientistsEngineersUse their education to acquire new knowledgeUse their education to develop usable devices, structures and processesSeek to knowAim to do

What is a Civil Engineer?One who improves the quality of life through the production of infrastructureBuildings, bridges and other structuresHighwaysDams and leveesWater treatment plants, waste disposalThis infrastructure must be safe, functional, elegant and economically sound

4

Why We Need Civil EngineersMake sure our human habitat is livableMake sure we use resources wiselySustainable developmentHelp maintain our competitiveness in the global economyIncrease productivity

Geotechnical EngineeringGeotechnical Engineering is concerned with engineering behavior of earth materialsGeotechnical engineers:Investigate existing subsurface conditions (tunnels excavations, pipelines)Determine physical and chemical properties relevant to project consideredAssess risks posed by site conditionsDesign earthworks and structural foundationsMonitor earthwork and foundation construction

The World IslandsA modern marvel of geotechnical engineering!

The World Islands Fun FactsLocated 2.5 miles off the coast of Dubai, United Arab Emirates

The 300 islands are composed of 321 million cubic meters of sand and 31 million tons of rock

The land used to create the islands largely consists of sand dredged from Dubais shallow coastal waters

Overall development costs are estimated at $14 billion USD

Cost for full ownership of one of the undeveloped islands ranges between $10 million and $45 million USD

Transportation EngineeringPlanning, Design, Operation and Maintenance of safe and efficient transportation systems

Incorporating new technologies to improve system performance

Intelligent Transportation Systems

Pretty Amazing!A WATER BRIDGE .. OVER A RIVER!!!

Activity Penny BoatsConstruct your boat using only one piece of the heavy duty aluminum foil provided.Predict how many pennies your boat will hold: _______________Slowly add pennies to your boat. Once water enters the boat, or if any part of the boat touches the bottom of the container, your turn is over.The last penny added will not count in the total amount held.
