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 24BI0049 (₱89.75M) is recorded as completed in 38 days against 311 planned; similar-cost projects take a median of 285 days, putting it in the fastest 0.3%. The project may have been substantially completed earlier, or the recorded completion date may reflect only paperwork or a reporting artifact.
