During the design phase, Design Development is typically associated with which of the following?

• A. 60% design
• B. 30% design (DD)
• C. 10% design
• D. 90% design

Answer: (B)

Design Development follows the initial concept phase and focuses on refining and coordinating the design across disciplines. In this stage the layout is solidified, major building systems are sized and coordinated, and more precise dimensions and material choices are documented. The goal is to resolve key design decisions and produce coordinated drawings and specifications that support cost estimates and procurement planning, while still allowing for adjustments before final documentation. This work is typically associated with about thirty percent of the total design effort, marking a point where the design is concrete enough to evaluate constructability and costs but not yet finalized in full construction documents. The next phase builds on this by completing the detailed drawings and specs for construction.
