This document provides a course description for FCE 311 - Geotechnical Engineering I, a 3rd year undergraduate course offered by the University of Nairobi's Department of Civil and Construction Engineering. The course is an introduction to soil mechanics, focusing on soil formation, structure, physical properties, classification, compaction, and permeability. Through lectures, examples, discussions, and assigned reading, students will develop an understanding of soil engineering properties and how to apply basic analytical procedures and laboratory testing methods to solve engineering problems involving soil. Assessment will include laboratory tests, continuous assessment tests, and a final exam.
