OBJECTIVES:

• To impart to the student knowledge of types of shallow foundations and theories required for the determination of their bearing capacity.
• To enable the student to compute immediate and consolidation settlements of shallow foundations.
• To impart the principles of important field tests such as SPT and Plate bearing test.
• To enable the student to imbibe the concepts of pile foundations and determine their load carrying capacity.
