Design Development: A stage subsequent to schematic design where the schematic design decisions are worked out in greater detail. A clear and coordinated description of all aspects of the design including Architectural, Structural, Mechanical, Plumbing, Electrical and Fire Protection Systems is worked out providing a basis for the preparation of construction documents. Construction Manager assists Owner and architect in determining potential cost savings, energy efficiency, and constructability improvements. At the end of the design development phase the architect will provide the client with drafted to-scale drawings that will illustrate the project as it would look when it’s constructed. These drawings will very specifically define the site plan, floor plans and exterior elevations. It is important that the client provide input to the architect at this time as the design development drawings are used as the basis for the construction drawings and preliminary cost estimates in building a home.
