AACE CEP Estimate Review, Validation, and Reconciliation

Estimate review is a control process. It checks whether the estimate is complete, traceable, internally consistent, and suitable for the decision it will support.

Review focus

A strong review checks:

• scope coverage and exclusions
• estimate basis and assumptions
• quantity and pricing sources
• labor productivity and crew assumptions
• indirect cost treatment
• escalation and contingency treatment
• estimate classification and accuracy expectation
• consistency with schedule and procurement strategy
• arithmetic, coding, and summarization

The exam may present a technically detailed estimate with a weak basis. Do not be distracted by volume. The issue is whether the estimate can support the decision.

Validation and benchmarking

Validation compares the estimate with independent checks, historical data, benchmarks, ratios, or alternate methods. A large difference does not automatically mean one method is wrong. It signals the need to investigate scope, timing, location, productivity, indirects, escalation, or risk treatment.

Reconciliation

Reconciliation turns differences into a defensible estimate. The estimator should document why changes were accepted or rejected. If uncertainty remains, it should be communicated as a range, risk, or limitation.

Sample Exam Question

An estimate review finds that the bottom-up estimate is 18 percent higher than a recent benchmark. What is the best next action?

A. Replace the bottom-up estimate with the benchmark.
B. Keep the bottom-up estimate and ignore the benchmark.
C. Reconcile the difference by checking scope, location, timing, productivity, indirects, escalation, and risk assumptions.
D. Average both numbers and issue the estimate.

Best answer: C

Why: A material difference requires investigation and reconciliation before the estimate can be relied on.

Why the others are weaker: A and B choose a source without analysis. D hides the difference instead of explaining it.
