What is the difference between design development and construction document drawing sets for sizes, scales, and detail?

• A. DD includes more resolved dimensions and sections; CDs include final details and precise quantities for bidding and fabrication.
• B. CDs include final details and precise quantities for bidding and fabrication.
• C. DD is used for marketing; CDs are used for conceptual design.
• D. DD and CDs are identical.

Answer: (D)

The main idea is that design development and construction documents serve different purposes and levels of detail in the design process. In design development, drawings are developed to show how the design concept will sit together, with more specific layouts, elevations, and systems, and a clearer sense of size and relationship. You’ll see more resolved dimensions and cross-sections than in earlier design stages, but the drawings stop short of final construction details and exact fabrication information. In construction documents, the drawings are prepared to be issued for bidding and construction, so they present fully resolved details, precise dimensions, and coordinated information across trades. They include final detailing, material specifications, and schedules that enable accurate quantities and fabrication or installation, with everything coordinated to a single, integral set of documents. So the key difference for sizes, scales, and detail is that design development increases specificity to convey intent, but construction documents provide the final, fully detailed, and quantity-enabled drawings used for building.
