Indicator C3 — Duplicate or Near-Duplicate Projects

AI-verified / Na-verify ng AI Data as of October 21, 2026

Duplicate or Near-Duplicate Projects

Very similar descriptions within ~100m or identical coordinates across contracts/years.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: contracts 24AC0002 and 22AC0007 have near-identical descriptions about 165 m apart (funding years 2022, 2024; ₱36.96M, ₱45.24M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only 'Barangay' vs 'Brgy.' as a difference, which is a spelling variant and not a distinguishing marker. Both projects are for 'Construction of Flood Control along Sinait River, Barangay/Brgy. Pug-os, Sinait, Ilocos Sur', funded in different years, and are only 165 meters apart. There are no phase, package, section, or other location markers that would distinguish them as separate works. The evidence is complete and meets the rule's criteria.
