 When do we need Geotechnical Engineer?

3.  The great liability of the engineer …compared to
men of other professions……is that his works are
out in the open where all can see them. He
cannot bury his mistakes in the grave like the
doctors.
He cannot, like the Architect, cover his figures with
trees A design engineer’s responsibility should
include assuring the structural safety of the
design, details, checking shop Drawing. Detailing is
as important as design.

4.  Geotechnical Engineering... That is, Soil
mechanics is the application of the laws and
principles of mechanics and hydraulics
to engineering problems dealing with soil as
an engineering material. In particular it is
concerned with the interaction of structures with
their foundation material.
Introduction to Geotechnical Engineering :

5. What is Geotechnical
Engineering?
• GEO- Means Earth.
• Technical – having
special knowledge
• What do they do?
– Go out to construction
sites to test soil
– Bring soil back to the
lab to test

6. Why Geotechnical
Engineering is Important?
Some of the important properties of soils that are
used by geotechnical engineers to analyze site
conditions and design earth works, retaining
structures, and foundations are: Specific weight
or Unit Weight. Cumulative weight of the solid
particles, water and air of the unit volume of soil.

7. When do we need
Geotechnical Engineers?
 Whenever there is construction!
 Roads
 Bridges
 Buildings
 Excavations
