DESCRIPTION - summary of the module content
AIMS - intentions of the module
To introduce: the basic concepts of engineering geology and ground investigation procedures and understand the basic principles of foundation design. Fieldwork: Interpretation of geological features in the field while gaining experience of field observation and measurement techniques, site investigation and preliminary design of a civil engineering structure. To develop the essential awareness of ground conditions and general safety on civil engineering sites.
