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 24AJ0049 and 22AJ0062 have near-identical descriptions about 55 m apart (funding years 2022, 2024; ₱19.20M, ₱19.59M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or covers an adjacent section not clearly labeled.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both refer to slope protection along San Juan River in Barangay/Brgy. Turac, San Carlos City, Pangasinan, and are only 55 meters apart. There are no distinguishing markers such as phase, package, section, or different sitios/barangays/structure types. The only differences are 'Structure' vs 'Works' and 'Barangay' vs 'Brgy.', which are not distinguishing per the rule. The evidence is complete and meets the rule's criteria for a plausible duplicate or overlapping project.
