4. Design Development

During this phase the Designer refines the project, establishes the scope, relationships, forms, size and appearance of the project by means of plans, sections and elevations, typical construction details, equipment layouts, and three-dimensional visualizations.

Although some design issues will continue to be refined, resolved or modified during the construction documents, bidding, and construction phases of the project, the primary achievement is to enable the Client to understand how the project will function as well as give more detail about what it will look like.

The Design Development Documents shall also include specifications of the materials, finishes, furnishings such as furniture, lighting, flooring, wall covering, and artwork that will identify major materials and systems and establish in general their quality levels.

Depending on the complexity of the project, the Designer also might submit drawings for approval by a construction inspector to ensure that the design meets building codes. If a project requires structural work, the Designer works with an Architect or Engineer for that part of the project.

Once the Design Development phase is approved, the project moves into the Construction Documents phase.
