17.0 Appendix F - Symbols Index

The Symbols Index includes a full range of standard symbols used throughout the construction industry.

Covered in this Appendix are standard symbols, their graphic representation, and their role in creating,

understanding, and fulfilling the intent of construction documents. Standard symbols ensure clear and

concise communication among the architect, engineer, owner, contractor, and consultants.

17.1 Classification

Symbols used in drawings are classified in terms of type:

17.1.1 Identity (ID) symbols indicate individual objects and are used generally in mechanical and

electrical drawings. Such symbols are valves fire alarms, light fixtures, and electrical outlets. These symbols

may be either scale dependent or independent.

17.1.2 Line (LINE) symbols indicate continuous objects and are either single or multiple lines. Walls are

usually drawn with two lines and ducts may be drawn with one or two lines based on the scale of the drawing.

Site and building utilities are drawn with one line with breaks in the line for a letter(s) to identify the utility

line. Some lines are solid, some are dashed, and some combine both. These symbols are scale independent.

17.1.3 Material (MATL) symbols graphically indicate certain materials and are used to help the reader

differentiate one material from another. These symbols may be in elevation, vertical, or horizontal section.

These symbols should be used as necessary but not overdone and used where a material begins and ends or

changes direction. Such symbols are used to designate earth, concrete, stone, steel, wood, and insulation.

Symbols are drawn in an appropriate size and scale of the drawn object. A material symbol may change

based on the scale used or the view presented of the object. These symbols can be either scale dependent

or independent.

17.1.4 Object (OBJ) symbols resemble the actual objects being symbolized. Such symbols are doors,

some with the direction of swing indicated, windows, toilet fixtures, and furniture. These symbols are scale

dependent.

17.1.5 Reference (REF) symbols refer the reader to information in another area of the set of drawings

or give basic information regarding the drawing or data on the drawing. Such symbols are exterior and

interior elevation indicators, building section indicators, partial building section indicators, and detail

indicators. Included with these symbols are drawing block titles, graphic scales, north indicator, room

identifiers, door/borrowed lite identifiers, window type identifiers, louver type identifiers, wall type

identifiers, furniture, fixture and equipment identifiers, identification device (sign) identifiers, key note

identifiers, leaders, dimension lines with terminators, match lines, and revision clouds with identifiers. These

symbols are scale independent.

CADD Standards

17.1.6 Text (TEXT) symbols graphically indicate a commonly used word or words that may be used in

notations on drawings, such as ±, ≤ X°. The text symbols provided are commonly used. For letter symbols,

dimensionless numbers, mathematical symbols, and subscript symbols see the ASHRAE Handbook -

Fundamentals.
