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: 7 contracts awarded to DRAGON TWELVE BUILDERS & CONST SUPPLY by the same office started within 41 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. These may be separate flood control projects for different barangays and river sections, planned together for efficiency.

Checked: October 22, 2026

This is a textbook C5 case: 7 contracts, same contractor and DEO, all within 41 days, each just under the ₱50M threshold, with 4 in the same municipality. The titles show different barangays and river sections, as expected for C5 (which clusters projects in one municipality). There is no data artifact or false positive; the evidence is complete and clear.
