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 DRAGON TWELVE BUILDERS & CONST SUPPLY by the same office started within 0 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. It is common for flood control projects to be split across different rivers and barangays within a district for logistical or engineering reasons.

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, all started on the same day, with three in the same municipality. The titles name different rivers/barangays, which is expected for C5 (the rule is designed for clusters of similar-sized projects in one area, not for duplicate detection). There is no data artifact or false positive here.
