Here is the list of abbreviations used in civil engineering drawings that are commonly used. These abbreviations are very useful and important because, in general practice, these are used in all civil engineering related discussions. Here are the list of abbreviations used in civil engineering. Also, Mentioned below are general abbreviations used in civil engineering.
