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 CENTERWAYS CONST AND DEVELOPMENT INC by the same office started within 112 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is common for flood mitigation projects to be distributed across several barangays within a municipality in a single year.

Checked: October 22, 2026

This is a textbook C5 case: four contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started within 112 days, and three are in the same municipality. The titles are similar but name different barangays, which is expected for C5 (the rule is about clusters in one municipality, not duplicate works). There is no data artifact or missing record.
