Architectural Symbols

A system of architectural symbols are used to indicate commonly used materials and features that

have been developed over the years. To read an architectural plan readily, you must have a good un-

derstanding of what the symbols represent on a drawing. It is not necessary to develope total recall of

each symbol, but is important to recognize what material or component each symbol represents when

a construction drawing. Symbols are designed to approximate the appearance of the material, fixture,

or component. There are hundreds of different types of symbols some of the more commonly seen

symbols on a construction plan are the door, window, and electrical symbol.

Typical door symbols

Typical Window Symbols

Typical electrical symbol

Typical plumbing symbols

how to read engineering drawing

Image titled Read Engineering Drawings Step 1 1 Familiarize yourself with the scale of the drawings. Understanding how large or small certain items are essential when reading engineering drawings. While most engineering drawings are created in "scale" versions of 1/4-1/8 inches (.55-.275 centimeters) per foot, other scales may be used for very large creations. Always determine the scale of the drawing before examining it in detail. If the scale is not obviously evident on the drawing, consult with the engineer who drew it for clarification. Image titled Read Engineering Drawings Step 2 2 Understand the basic symbols used in the engineering drawings. As these drawings are done on such a small scale, the use of symbols is often required. While many symbols exist, understanding a few of the basics can be very helpful when reading engineering drawings. Some of the most common symbols used in these drawings include rectangles, circles, and triangles. As with determining the scale, consulting with the engineer who created the drawing can provide great insight as to the symbols used. Image titled Read Engineering Drawings Step 3 3 Look for circled numbers. As discussed previously, engineering drawings are typically done on a scale so small that creating detail is almost impossible. Because of this, engineers often add circled numbers to certain parts of the drawings. These circled numbers indicate that the area identified is shown in greater detail on another page. Image titled Read Engineering Drawings Step 4 4 Identify specific abbreviations. Abbreviations are a useful tool for engineers. Like symbols, they can indicate shapes, processes, and even dimensions through a few letters. Some of the most common abbreviations used in engineering drawings include DP, which stands for depth, and DIA, which stands for diameter. Image titled Read Engineering Drawings Step 5 5 Work with colleagues. When all else fails, consult with other professionals to better clarify the drawings. While it may be embarrassing to admit that you are having difficulty interpreting the drawing, those who regularly work with and understand the drawings will help you read them. Ask "in the know" individuals on the project to clarify anything you do not understand; better that this happens in the early stages of a project than to encounter a mistake farther into a project because of improperly reading engineering drawings.

structural drawings

Structural Drawings: Structural Drawings are used to progress the Architect’s concept by specifying the shape and position of all parts of the structure – thus enabling the construction of that structure on site. Structural Drawings are also used for the preparation of the reinforcement drawings. Structural Drawings would typically include the following information: North Point Setting out dimensions for the concrete structure on site. Plans, sections and elevations showing layout, dimensions and levels of all concrete members within the structure. Location of all holes, chases, pockets, fixings and other items affecting the concreting work. Notes on specifications, finishes and all cross-references affecting the construction. Provide the detailer with the layout and sectional information required to specify the length, shape and number of each type of reinforcing bar. Reinforcement Drawings: Reinforcement drawings (or details), fully describe and locate all reinforcement in relation to the finished surface of the concrete and to any holes or fixings. They are primarily for the use of the steel fixers and it is preferable that they are kept separate from the general arrangement drawing. As a general rule, circular holes up to 150mm diameter and rectangular holes up to (150 x 150)mm in slabs and walls need not to be shown on the reinforcement drawings. For larger isolated holes with sides 500mm or less, either (i) displace affected bars either side of the hole,
