Civil engineering involves applying scientific principles to design, build, and maintain infrastructure and facilities. Some key points: - Civil engineers work to improve quality of life through infrastructure like buildings, bridges, roads, dams, and water treatment plants. - Their designs must be safe, functional, elegant, and cost-effective. Specializations include structural, transportation, environmental, and water resources engineering. - Notable projects include Dubai towers, the Eiffel Tower, Hoover Dam, and the Panama Canal. Emerging technologies and sustainable practices allow civil engineers to continuously enhance infrastructure.

1. Introduction
to Civil
Engineering

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. 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 Use their education to
new knowledge develop usable
devices, structures and
processes
Seek to know Aim to do

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

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

15. 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

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

18. 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
