Difficulty: Easy
Correct Answer: All of the above purposes
Explanation:
Introduction / Context:Before construction begins, decisions must be made with imperfect information. Estimates translate scope and market assumptions into a best available approximation, not a guarantee. Understanding the intent of estimating avoids overconfidence and ensures appropriate contingencies are carried.
Given Data / Assumptions:
Concept / Approach:Good estimates are transparent about basis, inclusions, exclusions, and risks. They support choices such as go/no-go, scope trade-offs, and procurement strategy by offering a reasoned approximation of cost. While later reconciled to actuals, the estimate's role is to frame expectations, not to certify exact outcomes in advance.
Step-by-Step Solution:
Define the estimate's objective: inform decisions with an approximate cost.Include the right structure: direct costs, indirects, overhead, contingency.Communicate uncertainty bands rather than a single-point false precision.Verification / Alternative check:
Compare estimate classes: conceptual (wide range) to definitive (narrower range) to validate that even at best the result is an approximation.Why Other Options Are Wrong:
Asserting an estimate certifies the exact final cost ignores market risk, scope changes, and unforeseen conditions.Common Pitfalls:
Understating contingency; failing to document assumptions, which hinders later reconciliation.Final Answer:
All of the above purposes
