Design development phase: Overview, definition, and example
What is the design development phase?
The design development phase is a critical stage in the project lifecycle, typically following the conceptual design and preceding the final construction documentation. It involves refining the design concepts into more detailed and practical plans that can be used for construction. During this phase, the initial ideas are developed further, incorporating technical specifications, materials, systems, and overall design details to ensure the project can be successfully built. The design development phase is important because it bridges the gap between concept and execution, providing a clearer understanding of how the project will look and function once completed.
For example, in architecture, the design development phase might involve finalizing floor plans, choosing building materials, and ensuring that structural, electrical, and plumbing systems are integrated into the design.
Why is the design development phase important?
The design development phase is important because it transforms the initial conceptual designs into actionable plans that can be built. It helps identify potential challenges and refine the scope of the project, preventing costly changes during later stages of construction. This phase ensures that the design is feasible from both a technical and financial standpoint, helping to avoid surprises during construction. It also provides an opportunity to engage stakeholders, gather feedback, and make adjustments before the project moves into construction.
For businesses and project owners, a well-executed design development phase can lead to more accurate cost estimates, smoother construction processes, and a higher-quality final product. For contractors, it ensures that they receive clear and complete instructions on what needs to be built, which minimizes risks and delays.
Understanding the design development phase through an example
In a commercial office building project, the design development phase would involve taking the initial concept design and fleshing it out with detailed specifications. The architect and engineers would finalize the floor plans, select materials such as flooring and wall finishes, and determine the necessary structural and mechanical systems. For example, the design team might decide on the types of HVAC systems, lighting designs, and the layout of electrical circuits. This detailed plan would then be used as the basis for the next phase—preparing the final construction documents.
In another example, a residential home design might progress from the conceptual sketches of a new house to more detailed plans. The design team would specify where windows and doors are placed, decide on materials like roofing and siding, and finalize the interior layout with dimensions for kitchens, bathrooms, and living spaces.
An example of a design development phase clause
Here’s how a design development phase clause might appear in a contract:
“The Architect shall proceed with the Design Development Phase upon approval of the Conceptual Design by the Owner. During this phase, the Architect will develop the design to include detailed plans, elevations, and specifications, including the selection of materials and systems. The Architect will provide the Owner with regular progress updates, and any changes to the design will be discussed and agreed upon before proceeding to the next phase.”
Conclusion
The design development phase is a key step in turning conceptual ideas into a practical, buildable project. It refines designs by adding the technical details, material choices, and system integrations needed for construction. This phase is crucial for minimizing risks, ensuring that the project is feasible, and providing clear direction for contractors. By thoroughly developing designs during this phase, stakeholders can ensure that the project proceeds smoothly into the construction phase and meets all expectations.
