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: 5 contracts awarded to ALCEL CONST by the same office started within 73 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. It is common for flood control projects to be distributed across multiple barangays and rivers within a municipality, each requiring separate contracts.

Checked: October 22, 2026

This is a textbook C5 case: five contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO within 73 days, with four in the same municipality. The titles name different barangays and rivers, which is expected for C5 (the rule is designed for clusters of similar works in one area, not for duplicate detection). There is no data artifact or false positive here.
