Indicator C5 — Pattern Consistent with Contract Splitting

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

Pattern Consistent with Contract Splitting

Multiple similar contracts to the same contractor/DEO just under a threshold in a short window.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: 3 contracts awarded to VEN RAY CONST CORP by the same office started within 114 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is common for flood control projects to be distributed across different rivers and barangays within a municipality.

This is a textbook C5 case: three contracts, same contractor and DEO, all just under the ₱50M threshold, started within 114 days, and all in the same municipality. The titles name different rivers/barangays, but C5 expects projects to be at different sites within the same municipality. There is no data artifact or false positive here, and the evidence is complete.
