Which portion of project documents communicates the unit system used for dimensions?

• A. Drawing
• B. Construction Schedule
• C. Equipment List
• D. Change Order

Answer: (A)

The unit system for dimensions is communicated on the drawings. Drawings are where all measurements and dimension callouts appear, and they typically include a note in the title block or a general note on the sheet specifying whether dimensions are in inches, millimeters, or another unit. This makes the drawings the authoritative source for how things are measured and built. Other documents like the construction schedule, equipment list, or change orders focus on timing, items, or changes in scope, not the measurement units used for dimensions. They won’t tell you what units to use—that information is established in the drawings.
