Indicator C4 — Schedule / Date Anomalies

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

Schedule / Date Anomalies

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 23AH0071 (₱49.00M) is recorded as completed in 76 days against 201 planned; similar-cost projects take a median of 239 days, putting it in the fastest 2.4%. The contractor may have deployed extra resources or worked in favorable conditions, enabling faster completion.
