_____ estimating has no flexibility and uses 100% complete designs.

• A. Detailed
• B. Rough
• C. Conceptual
• D. Parametric

Answer: (A)

In estimating, the level of design maturity drives how fixed the cost estimate is. When the design is fully developed, with 100% complete drawings and specifications, you can perform exact quantity takeoffs, apply fixed unit costs, and price the project with minimal guesswork. This produces a detailed estimate that directly reflects the final scope, and it’s typically used for bids or owner approvals where the price needs to be precise. Because the design is fully defined, there’s little to no flexibility to change quantities or scope without triggering redesign and a new estimate. That’s why this approach is described as detailed estimating. The other options come from earlier stages or alternative methods: conceptual and rough estimates rely on incomplete designs and more assumed data, while parametric estimates use cost relationships and can be less tied to a fully developed design.
