COURSE NO: G03-001
An Introduction to Identification and Classification of Soil and Rock
Course Highlights

This online engineering PDH course will introduce you to the principles and practices of identification and classification of soil and rock. Identification and classification are the essential first steps in soil mechanics and engineering, and engineering of foundations for structures such as buildings, dams and bridges. This course will provide you with an understanding of the soil and rock materials in order to proceed with the engineering analysis and design of a specific project.


This 3 PDH online course is intended for geotechnical, environmental and structural engineers, design professionals, and construction personnel who are interested in gaining an understanding of the basic principles of soil and rock identification and classification.
