Individual drawings may be referenced many times throughout a set of construction drawings. Because of the complexity and space required, many symbols do not have any graphic relationship to the items they represent. Think you can identify what these common construction and blueprint symbols mean? Enjoy! The symbols discussed in this chapter are not all-inclusive by any means, but they are the ones that the builder or designer is likely to encounter in most general building-construction applications. One of the vital aspects of graphic symbols on construction drawings is to cite other drawings inside the set. Check notations, detail drawings, and specifications for identification. c. legend. Abbreviations are often used in place of a graphic symbol in order to reduce drawing time and space. Many component symbols are similar to the actual item represented in plan/elevation view. Symbols for Electrical Construction Drawings (ANSI) This publication describes graphic symbols used to represent electrical wiring and equipment on construction drawings. Electrical Wiring Symbols, Meanings and Drawings - Detailed Chart and List of All Electrical Symbols and their Function.

In brickwork, the drawing should contain straight lines. It should be noted that on some HVAC drawings one sees two types of symbols. 3 can be seen on drawing No. Blueprint drawings—as applied to the building-construction industry—are generally used to show how a building, object, or system is to be constructed, implemented, modified, or repaired. Reading blueprints requires a good understanding of line types. Standard schema symbols in electrical drawings represent circuit breakers, transformers, capacitors, bus bars, conductors, and many other details on drawings. Most drawings prepared during the later stages of the design and construction of buildings might be considered to be technical drawings. Figure 8.4A and B show various door, window, and wall symbols used in general construction. The identification of lines and other symbols on a construction drawing is called the a. index b. title block c. legend d. scale.
