Which phase provides detailed plans and elevations that clearly define the nature of the project?

The phase that provides detailed plans and elevations which clearly define the nature of the project is known as Design Development. In this phase, the initial concepts developed during the Schematic Design phase are elaborated upon, resulting in construction documents that specify the project's design intent more concretely. These documents include detailed drawings and specifications that outline the building’s layout, dimensions, materials, and systems, ensuring that all stakeholders have a clear understanding of the project's specifications.

By the end of Design Development, significant elements such as structural, mechanical, electrical, and plumbing systems are further defined, making it easier for contractors to understand the requirements before construction begins. This clarity is crucial as it helps prevent misunderstandings and changes later in the project, which can lead to delays and increased costs. The attention to detail achieved in this stage plays a vital role in the successful execution of the project.
