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 possible that these are separate flood control projects planned for different sites as part of a coordinated flood mitigation program.

This is a textbook C5 case: 14 contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO within 62 days, with 5 in the same municipality. The titles and locations are all present and describe different flood control structures in various barangays and municipalities, as expected for this rule. There is no evidence of a data artifact or false positive. The indicator is genuinely unusual and meets all rule criteria.
