| Conceptual structural design describes the earliest stages in the development of a structural engineering project. While innumerable tools are available to assist the structural engineer in the later stages of design, this is not the case during conceptual design. The engineer has relatively few structured techniques to augment experience and intuition at this phase. The early stages of design are characterized by greater fluidity, abstraction, and uncertainty than the later stages. As designs progress, concepts become more concrete while the level of uncertainty decreases. A wide range of techniques, both deterministic and probabilistic, are available to evaluate the performance and reliability of a system at this stage. It is widely accepted that the earlier in the design cycle a decision is made, the greater the overall cost implications. | |

| The earlier a design may be validated for future consideration or excluded, the more efficiently those resources may be allocated to explore the most beneficial design alternatives. | |
