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 11-16 CONST by the same office started within 23 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible these are separate flood control projects in different barangays, each requiring its own contract.

This is a textbook C5 case: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO within 23 days, with three in the same municipality. The titles refer to different specific sites (different barangays/sections), but C5 is designed to flag clusters of near-threshold contracts in one municipality, regardless of whether the sites differ. There is no evidence of a data artifact.
