FOUNDATION ENGINEERING

AIM

-To learn about types and purposes of different foundation systems -To provide students with exposure to the systematic methods for designing foundations. -To discuss and evaluate the feasibility of foundation solutions to different types of soil conditions considering the time effect on soil behavior. -To build the necessary theoretical background for design and construction of foundation systems.
