This module aims to provide students with basic knowledge and skills in civil engineering mechanics. It will cover topics including statics, motion, and hydrostatics over 60 hours of instruction divided into sections. Assessment will be through phase tests. The content is designed for technician students and should be taught with examples applicable to civil engineering works.
