The ductwork on a shop drawing is without detail and dimension.

• A. Yes
• B. Sometimes
• C. Not specified
• D. No

Answer: (D)

Shop drawings for ductwork must provide precise, dimensioned details so the fabricator can cut, assemble, and install exactly as designed. When details such as sizes, lengths, diameters, offsets, connection types, material gauge, seams, fittings, and even hanger locations are missing, the shop cannot fabricate accurately and field installation becomes guesswork. This almost always leads to errors, rework, clashes with other systems, and performance problems like leaks or improper airflow. Therefore stating that the ductwork on a shop drawing is without detail and dimension is not acceptable—the correct response is No. Other options imply that missing details might be acceptable or undefined, which contradicts the need for exact fabrication information in shop drawings.
