Rationale:

Civil Engineering diploma engineers are required to supervise the construction of roads, pavements, dams, embankments, and other Civil Engineering structures. As such the knowledge of basic soil engineering is the pre-requisite for these engineers for effective discharge of their duties. This necessitates the introduction of Soil and Foundation Engineering subject in the curriculum for Diploma Course in Civil Engineering.
The subject covers only such topics which will enable the diploma engineers to identify and classify the different types of soils, their selection and proper use in the field for various types of engineering structures.
The emphasis will be more on teaching practical aspect rather than theory.

Learning Outcomes:

After undergoing the subject, students will be able to:

• Identify and classify various types of soils
• Select particular type of foundation according to loading of structure
• Determine shear strength of soil
• Carry out compaction of soils as per density
• Calculate bearing capacity of soil
• Calculate liquid limit and plastic limit of soil
• Calculate maximum dry density of soil and optimum moisture content of soil
• Perform various tests of the soil
• Apply different techniques for improving the engineering properties of soil.

Instructional Strategy:

The teacher while imparting instructions are expected to lay greater emphasis on the practical aspects rather than theory and mathematical treatment. To bring clarity regarding concepts and principles involved, teachers should organize demonstrations in the laboratories and fields. It is necessary to create understanding that soils fail either under shear or settlement due to heavy loads. This can be shown by making use of photographs on working models of such failures. Efforts should be made in the practical classes that students perform practical exercises individually. Conduct of viva examination at the end of each practical work will develop clear understanding about the concepts and principles related to this subject.

Means of Assessment:

1. Assignments and quiz/class tests
2. Mid-term and end-term written tests
3. Actual Practical Performance
4. Presentation
5. Viva-voce
