All the works of civil engineers must rest upon soils or rocks. Regardless of your future field of specialization, whether it will be in structures, construction, transportation, water resources or environmental, you will need to know how your new project will interact with the local soils and rocks. The study of how soils and rocks behave, from an engineering point of view, is called soil and rock mechanics . The design of civil works in and upon these materials is called foundation engineering . Their combination is geotechnical engineering , which is the common thread that binds all the civil engineering fields together. The geotechnical engineering course at FIU is divided into two parts: analysis and design. (1) Analysis . This first part (a) studies the origins of soils and rocks, which are then, (b) classified and named according to their formation to establish a common language among engineers worldwide, (c) studies the effect of water upon their behavior and then (d) establish their engineering properties (strength and deformation) when subjected to loads from structures, water, earthquakes, etc. Our laboratory sessions will permit each student to experience first- hand these properties, and to develop a deeper insight of soils and rocks as new structural and environmental materials. Our syllabus is as follows:

(2) Design . The second part of geotechnical engineering employs the analytical base of soil and rock mechanics and complements it with structural theory, construction methods and hydraulics to develop a field of knowledge known as foundation engineering .
