Indicator C4 — Schedule / Date Inconsistencies

AI-verified / Na-verify ng AI Data as of October 21, 2026

Schedule / Date Inconsistencies

Completion before start, implausible duration for cost, or future dates marked complete.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: contract 23CJ0144 (₱57.19M) is recorded as completed in 73 days against 191 planned; similar-cost projects take a median of 285 days, putting it in the fastest 1.9%. This may be due to efficient project management, favorable conditions, or overestimated planning timelines.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

The project was completed in 73 days, which is much faster than both the planned duration (191 days) and the peer median (285 days), placing it in the fastest 1.9% of similar-cost projects. All relevant figures and record links are present, and the anomaly is clear and checkable. Innocent explanations (e.g., favorable weather, pre-fabrication, or overestimated planning) are plausible but do not negate the anomaly.
