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 ST MATTHEW GEN CONTRACTOR & DEVELOPMENT CORP by the same office started within 0 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is possible that these are separate projects for different barangays that happened to be procured at the same time.

This is a textbook C5 case: three contracts, same contractor and DEO, all started on the same day, each just under the ₱50M threshold, and all in the same municipality. The titles specify different barangays, but C5 expects projects to be at different sites within the same municipality. There is no data artifact or error, and the evidence is complete.
