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: 14 contracts awarded to 739 BUILDERS by the same office started within 62 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 5 in the same municipality. It is common for flood control projects to be distributed across multiple sites within a province, each requiring a separate contract.

Checked: October 22, 2026

This is a textbook C5 case: 14 contracts, all just under the ₱50M threshold, awarded to the same contractor and DEO within 62 days, with 5 in the same municipality. The titles clearly refer to different flood control structures in different barangays or locations, as expected for C5. The code has already confirmed the cluster math and thresholds. There is no evidence of a data artifact.
