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: 4 contracts awarded to VEN RAY CONST CORP by the same office started within 36 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is common for flood mitigation projects to be distributed across several barangays within a municipality in a single funding year.

This is a textbook C5 case: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started within 36 days, and three are in the same municipality. The titles are similar but name different barangays/rivers, which is expected for C5 (the rule is about clusters in one municipality, not duplicate works). There is no evidence of a data artifact or false positive.
