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 24BG0020 (₱96.48M) is recorded as completed in 48 days against 322 planned; similar-cost projects take a median of 285 days, putting it in the fastest 0.5%. The project may have benefited from unusually efficient work methods or pre-fabrication.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

The project was completed in 48 days, which is extremely fast for its value (₱96.48M), compared to a median of 285 days for similar-cost projects. The evidence is complete, with all relevant record IDs and URLs provided. There is no data artifact or legitimate reason in the packet to reject. Innocent explanations (e.g., pre-fabrication, over-reporting of completion, or unusually efficient work) are plausible but do not block publication.
