INTRODUCATION (PART1)

1. 1. Introduction to Civil Engineering
2. 2. What is Engineering The word engineer originates from the Latin term ingenerare, meaning to invent, to create or to regulate It is the professional art of applying scientific principles to every day things to help make life easier
3. 
   
4. 3. 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 work Scientists Engineers Use their education to acquire new knowledge Use their education to develop usable devices, structures and processes Seek to know Aim to do
5. 4. 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
6. 5. 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

14. 13. Dubai’s expansion from 1991 to 2005
15. 14. 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
16. 15. The World Islands A modern marvel of geotechnical engineering!
17. 16. 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
18. 17. Transportation Engineering Planning, Design, Operation and Maintenance of safe and efficient transportation systems Incorporating new technologies to improve system performance Intelligent Transportation Systems
19. 18. 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

26. 25. • Lesson: – Goals the same, techniques change One last example …
27. 26. Pretty Amazing! A WATER BRIDGE .. OVER A RIVER!!!
28. 27. 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.
