DD

Definition

DD, or Design Development, refers to a phase in the architectural and engineering design process where the initial schematic designs are developed into more detailed and refined plans.

Purpose

The purpose of the Design Development phase is to further develop the project's design, addressing specific details, materials, systems, and dimensions. This phase ensures that the design concept can be realistically implemented within the project's budget and constraints, setting the stage for the construction documents phase.

Examples of Use

1. Architectural Projects: In an architectural project, DD involves refining floor plans, elevations, and sections, and selecting materials and finishes.
2. Engineering Systems: Developing detailed plans for structural, mechanical, electrical, and plumbing systems during the DD phase of a building project.
3. Interior Design: Finalizing the layout, materials, and finishes for the interiors of a commercial space during the DD phase.

Related Terms

• Schematic Design (SD): The initial phase of design where the basic concept and general layout are developed.
• Construction Documents (CD): The final phase of design where detailed drawings and specifications are prepared for construction.
• Project Management: The overall planning, coordination, and control of a project from inception to completion.

Notes

• The Design Development phase is crucial for identifying and resolving potential issues before moving into the more detailed construction documents phase.
• Collaboration among architects, engineers, and other stakeholders is essential during DD to ensure all aspects of the project are aligned.
• Changes made during DD can significantly impact the project's cost and schedule, making thorough review and approval processes important.
