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 21CM0058 (₱77.20M) is recorded as completed in 76 days against 209 planned; similar-cost projects take a median of 285 days, putting it in the fastest 2.1%. The project may have been completed quickly due to favorable weather, efficient management, or early preparation.
