  1. What does a 'keynote' system on construction drawings accomplish?

    Answer: It replaces lengthy notation on the drawing with a number that refers to a legend or specification section

    Keynotes replace verbose annotations on drawing sheets with short numeric or alphanumeric codes that reference a keynote legend or specification section for full descriptions.

  2. On a structural plan, a column grid is typically identified by:

    Answer: Letters on one axis and numbers on the perpendicular axis

    Structural column grids conventionally use letters (A, B, C…) along one axis and numbers (1, 2, 3…) along the perpendicular axis, so any column can be identified by a coordinate such as 'B-3'.

  3. What is indicated when a dimension on a drawing is enclosed in a rectangle or box?

    Answer: The dimension is a reference or 'not-to-scale' value

    A boxed or reference dimension (REF) is provided for information only and does not control construction; dimensions without boxes govern.

  4. On fire protection drawings, a filled (solid) circle on a piping run typically represents:

    Answer: A sprinkler head

    Sprinkler heads are commonly shown as solid circles or circles with a line on fire protection plans, indicating the location of each suppression head.

  5. What does the abbreviation 'N.T.S.' on a drawing mean, and how should it affect how you use the drawing?

    Answer: Not To Scale — measurements should not be scaled from the drawing

    N.T.S. (Not To Scale) warns that the drawing is diagrammatic or distorted and dimensions must be taken from numerical annotations only, not by measuring the printed image.

  6. A 'riser diagram' in mechanical or plumbing drawings shows:

    Answer: A schematic vertical view of piping or duct systems through the building height

    A riser diagram is a schematic (not to scale) vertical section showing how pipes or ducts are routed through multiple floors, including pipe sizes, valves, and connections at each level.

  7. When a drawing note says 'SEE STRUCTURAL' next to a penetration through a concrete wall, the specifier should:

    Answer: Refer to the structural drawings for reinforcing, sleeve sizing, and fire-stopping requirements

    Cross-references to structural drawings mean the governing details—such as sleeve dimensions, reinforcing layout, and any required fire-stopping—are located on those sheets.
