Which method is NOT considered a standard estimating technique?

The cost-benefit analysis is not considered a standard estimating technique in the context of construction and project estimating. Unlike techniques such as the square foot method, price per unit method, and conceptual estimate, which focus specifically on estimating costs associated with construction projects, cost-benefit analysis serves a broader purpose.

Cost-benefit analysis evaluates the overall financial implications of a project by comparing the costs involved against the benefits expected to be gained from it. It helps in decision-making but does not provide a direct estimation of project costs or resource requirements as the other techniques do. The square foot method estimates costs based on the area of the project, the price per unit method calculates costs based on individual items, and the conceptual estimate provides a rough idea typically based on historical data.

Thus, the distinction lies in the fact that cost-benefit analysis looks at the overall efficacy of a project rather than providing a specific method of estimating construction or project costs.
