Introduction to Civil Engineering
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
Engineer vs. Scientist• Deviations between engineers and
scientists arise through the differences in the ways both apply their educations in mathematical and natural sciences to their workScientists Engineers
Use their education to acquire new knowledge
Use their education to develop usable devices, structures and processes
Seek to know Aim to do
What is a Civil Engineer?• One who improves the quality of
life through the production of infrastructure– Buildings, bridges and other
structures– Highways– Dams and levees– Water treatment plants, waste
disposal• This infrastructure must be safe,
functional, elegant and economically sound
Why We Need Civil Engineers• Make sure our human habitat is
livable• Make sure we use resources wisely
– Sustainable development• Help maintain our competitiveness
in the global economy– Increase productivity

Specialization in Civil Engineering
Structural Engineering
Design of new structures
Upgrading existing structures
Intelligent use of new technologies and materials to control structural behavior
Structures include buildings, bridges, offshore platforms, transmission towers, and other specialized facilities

Construction Engineering
Concepts and designs become reality
Management skills
project cost estimating and scheduling
financial planning, labor coordination and supervision

Geotechnical Engineering
• Geotechnical Engineering is concerned with engineering behavior of earth materials
• Geotechnical engineers:• Investigate existing subsurface
conditions (tunnels excavations, pipelines)
• Determine physical and chemical properties relevant to project considered
• Assess risks posed by site conditions• Design earthworks and structural
foundations• Monitor earthwork and foundation
construction
The World Islands
A modern marvel of geotechnical engineering!
The World Islands Fun Facts
• Located 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 Dubai’s 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 Engineering
Planning, Design, Operation and Maintenance of safe and efficient transportation systems
Incorporating new technologies to improve system performance
Intelligent Transportation Systems
Environmental Engineering
Protect & improve environmental quality natural systems engineered systems
Protect human health & well-being provide safe drinking water waste water treatment systems hazardous waste site clean-ups
Environmental engineers turn disease into delicacy!

• Lesson:–Goals the same, techniques change
One last example …
Pretty Amazing!A WATER BRIDGE .. OVER A RIVER!!!
Activity – Penny Boats• Construct 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.
