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 24HE0059 (₱96.45M) is recorded as completed in 80 days against 306 planned; similar-cost projects take a median of 285 days, putting it in the fastest 2.3%. The project may have benefited from unusually efficient work, favorable weather, or overestimated planning duration.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

The project was completed in 80 days, which is much faster than both the planned duration (306 days) and the median for similar-cost projects (285 days), placing it in the fastest 2.3%. All relevant data is present and the anomaly is clear and checkable. Innocent explanations are possible (e.g., early completion due to favorable conditions or overestimated planning), but this does not block publication.
