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: 11 contracts awarded to A C SOLIVEN CONST & GEN MERCHANDISE by the same office started within 46 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 9 in the same municipality. It is possible that the projects were split to address different sections or urgent needs in various locations within the municipality.

This is a textbook C5 indicator: 11 contracts, same contractor and DEO, all just under the ₱50M threshold, started within 46 days, with 9 in the same municipality. The titles are similar but name different sections, rivers, or barangays, as expected for C5. The code already confirmed the cluster math and thresholds. There is no evidence of a data artifact.
