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: 5 contracts awarded to NFH CONST & SUPPLY by the same office started within 16 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 multiple barangays and rivers within a municipality, resulting in several similar contracts in the same period.

This is a textbook C5 indicator: five contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started within 16 days, with three in the same municipality. The titles name different barangays and rivers, which is expected for C5 (the rule is designed for clusters of similar-sized projects in one area, not for duplicate detection). There is no evidence of a data artifact.
