1. 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

2. Engineer vs. Scientist Scientists Engineers
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

3. 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

4. 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. 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. The World Islands
A modern marvel of geotechnical engineering!

17. 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. Transportation Engineering
