On construction drawings, abbreviations and symbols are widely used. Plans reviewers should be familiar with which of the following?

• A. Only common abbreviations
• B. Some of the more commonly used abbreviations and symbols
• C. All abbreviations and symbols
• D. No abbreviations

Answer: (B)

Abbreviations and symbols are shortcuts that convey a lot of information on drawings, so plan reviewers must be familiar with the ones you’ll most often encounter. Knowing the commonly used abbreviations and symbols lets you read layouts quickly and accurately without getting bogged down by a lengthy, impractical vocabulary. Every drawing set includes a legend or notes that define the symbols and abbreviations used for that project, so focus on the most frequent ones and use the legend as your reference. If you see something unfamiliar, refer to the drawing legend, project specifications, or standard references (such as NFPA 170 for fire-safety symbols) to verify meaning. Because there are many possible abbreviations across disciplines, being comfortable with the common ones and knowing how to verify others is the practical approach.
