The design prepared in the planning stage of a project and submitted as part of the project brief. The drawings and specification s that comprise the Preliminary Design should be clearly specified as a matter of policy and provide the basis for the Appropriation estimate. [D01243] CCCP
Preliminary Design (the second of the Acquisition Phase activities) converts the functional baseline from Conceptual Design (the ‘what' of the system) into a preliminary definition of the system physical architecture (the ‘how').
(IEEE) (1) The process of analyzing design alternatives and defining the architecture, components, interfaces, and timing and sizing estimates for a system or component. See: detailed design. (2) The result of the process in (1).
Crude designs used to try different approaches to solving garden design challenges.
The engineering and environmental studies associated with the development and comparison of alternate locations, alternate alignments, detailed analysis, ongoing public and agency interaction project review and final selection of a project alternative.
The process of analyzing design alternatives and defining the software architecture. Preliminary design typically includes definition and structuring of computer program components and data definitions of the interfaces, and preparation of timing and sizing estimates. The result of the preliminary design process. See also design analysis, functional design.
The final phase of work in the Project Development Work Program (PDWP) in which preliminary engineering work is performed and formal community and environmental approval of an Initially Preferred Alternative is obtained.
