Are mechanical room plans drawn to a larger scale than other floor plans?

• A. No
• B. Sometimes
• C. Always
• D. Yes

Answer: (D)

Mechanical room plans are drawn at a larger scale because they must clearly show the detailed layout of equipment, ductwork, piping, valves, and the required clearances. A bigger scale makes it possible to read dimensions accurately, annotate installation notes, and ensure proper coordination with structural openings and other trades. While there can be project-specific variations, the standard practice is to use a larger scale for mechanical plans, so the statement is correct.
